Balcony restoration: What condominium building owners should expect during construction

Building and Structural Restoration Balconies

How to minimize disruption and keep residents informed during a balcony restoration project

Balcony restoration represents both a challenge and an opportunity for condominium communities. It’s an important investment in the performance of the building, but it’s more than likely that its activities will disrupt existing residents.

Balcony restoration happens directly outside residents’ homes. They unwillingly live on the front lines of construction activities – dust and vibrations from jackhammering, interruptions from inspections and measurement taking and swing stages going up and down the wall past their units, become part of their new reality. There may be moments when progress isn’t obvious from the outside, leaving those residents frustrated.

The best way to stave off those frustrations is with effective planning, communication and expectation setting for residents.

Before construction begins

By the time a contractor is awarded the project, owners and tenants have usually seen engineers inspecting balconies and know repairs are coming. Once the tender closes, many expect construction to begin immediately.

However, there’s often a delay before crews arrive on site as contracts are finalized, permits are attainted, shop drawings reviewed and materials ordered.

Residents want to understand where the project stands, when work is expected to start and what they’ll need to do before construction begins.

By the time a contractor is awarded the project, owners and tenants have usually seen engineers inspecting balconies and know repairs are coming.

Preparing for the balcony restoration

One of the first steps in any condominium balcony restoration project is clearing the balconies.

Management needs to communicate when items like furniture, planters, flooring and other personal belongings need to be removed before work begins. This may be a simple task for some residents, while others may need extra time, or even assistance. Communicating these requirements early helps avoid delays once construction starts.

Once the balconies are cleared, access will be restricted until the work is complete, a necessity for everyone’s safety. This needs to be clearly communicated with a post on balcony doors.

Why construction seems to stop and start

Resident expectations of project progress may not align with the realities of a given project.

Balcony restoration is carried out in phases. First comes demolition and removal of guards, followed by inspections to confirm repair areas are properly prepared. Concrete repairs require curing time before waterproofing can begin, and waterproofing must cure before new guards can be installed.

Additionally, every phase needs to go through an inspection before the next one can begin. During those gaps between active construction work, residents may see this as progress being stalled, though this isn’t the case. Clear communication about project phasing can ease tensions that may arise from any misunderstandings.

Expect interruptions, like noise and weather delays

The most common resident complaints during balcony restoration arise because of noise and delays.

Concrete removal creates vibration that can be felt in neighbouring units, and the sound can travel farther than people expect. Providing residents with advance notice of noisy work helps them plan around it.

Weather also plays a bigger role than many people realize. Concrete can’t be poured in the rain. Waterproofing can’t be applied to wet surfaces. Extreme heat may shorten workdays.

It can look like nothing is happening, but often, the pros are simply waiting for the right conditions to move forward.

101 Kathleen Street: Restoring balconies of occupied units

It’s a point of pride that Pretium Engineering minimizes disruption while residents remain in place using clear, proactive communication throughout multifamily construction projects.

In the case of 101 Kathleen Street in Whitby, our team provided building enclosure consulting for the restoration of a six-storey, 120-unit condominium that was constructed in 1979.

The project included balcony concrete repairs and waterproofing, replacement of aging metal picket guards with modern aluminum and tinted glass guard systems, and an EIFS retrofit designed to improve building aesthetics and the thermal performance of the exterior wall and window assemblies.

It’s a point of pride that Pretium Engineering minimizes disruption while residents remain in place using clear, proactive communication throughout multifamily construction projects.

Because the building remained fully occupied throughout construction, careful coordination was critical. Our team collaborated with the contractor to phase the work, communicate milestones and manage resident expectations. By establishing clear communication channels from project outset and providing regular updates, we minimized both disruptions and impacts on residents.

The completed restoration delivered safer, more functional balconies, enhanced the building’s appearance and reduced energy costs by improving the overall performance of the building envelope.

Opening the balconies

To ensure everyone’s safety, balconies will be reopened in phases, once inspections have been completed and any deficiencies have been addressed.

While residents are naturally eager to get their outdoor space back, it’s better to wait for contractor confirmation than to promise a reopening date that may change.

The goal of balcony restoration is twofold: to revive a valued building amenity while causing as little disruption as possible. When technical expertise is matched with thoughtful planning and proactive communication, the result is a project that protects both the building and the resident experience.

Why Roof Performance and Resilience Matters More Than Ever in the Climate-Change Era

Building and Structural Restoration

Prioritizing Roof Performance Over Secondary Uses is Key for Structures Enduring Through Climate Change

Climate change is reshaping how buildings, and their roofs, perform.

The decisions engineers/consultants, institutional and commercial building owners, and property managers make today regarding both new construction and retrofits will directly impact a structure’s ability to withstand climate-related risks into the future.

Roofs are a building’s first line of defence against the elements, and they must be constructed to withstand higher wind loads, heavier rainfall, and more frequent freeze-thaw cycles. As a result, roof resilience is rapidly becoming a critical risk management and asset protection issue.

This creates a design tension, as ancillary roof uses become more popular. Building designers and project teams are often pressured to prioritize secondary roof uses or cost savings over long-term roof performance.

Green/vegetated roofs, solar photovoltaic arrays, water retention systems, communications infrastructure, and rooftop amenity spaces all add value by mitigating climate impacts, supporting sustainability goals, and creating functional spaces.

However, these benefits come with increased roof loads and long-term performance risks if roof systems are not designed with resilience top of mind.

The Argument for Prioritizing Roof Performance

Roofs must perform over the long term, remaining securely in place, preventing leaks during high winds and heavy precipitation, and maintaining occupant comfort. When roof systems fall short of these objectives, the resulting failures are often expensive and disruptive to fix.

An article in Canadian Architect calls for building codes to “get with the times” as climate risks intensify.

While essential, the codes establish minimum life-safety standards rather than focusing on durability, energy performance, or resilience. Roofs designed to code minimums may meet compliance requirements but could still underperform in real-world climate conditions.

It begs the question – do we need higher standards for building codes as the climate crisis worsens to better incorporate resilience in buildings?

For example, a voluntary standard exists for wind and drainage for commercial roofs in CSA A123.26, Performance Requirements for Climate Resilience of Low Slope Membrane Roofing Systems, setting the stage for designers to meet future climate changes.

Even when a design concept is sound and up to code, value engineering often targets roofing systems for cost reductions, meaning that materials could be downgraded, assemblies altered, and performance characteristics diminished. In the age of climate change, this could lead to faster wear and tear on the roofing components that range from small fixes to catastrophic damage.

This practice must change so that enduring roof system performance is top of mind in both new construction and roof retrofit projects.

When roof performance is prioritized first, ancillary uses can succeed without compromising its performance or the building envelope.

Balancing Roof Performance with Ancillary Uses

Ancillary roof uses add extra environmental, social, and economic value to commercial and institutional buildings, but these uses must be integrated into a long-term roof performance strategy, not layered on as an afterthought. Roofs overburdened with inadequate drainage, insufficient wind resistance, or minimal insulation are far more likely to fail.

Mitigating competing priorities requires informed decision-making, supported by qualified roof consultants and performance-driven standards that anticipate future climate conditions, energy costs, and technological advancements.

When roof performance is prioritized first, ancillary uses can succeed without compromising its performance or the building envelope.

Institutional and commercial roofs are increasingly central to climate resilience strategies, and the choices engineers, designers, building owners, and property managers make today about design standards, materials, insulation levels, and maintenance will be tested throughout the structure’s lifespan.

Those who prioritize resilient, high-performing roof systems now will be better positioned to protect their property, maintain operations, and successfully adapt their building to a shifting climate in the long run.

Building Envelope Investigations: Finding the Source of Leaks and Moisture Issues

Building and Structural Restoration

How Engineers Manage Water Intrusion to Prevent the Need for Major Building Repairs

The impacts of water on the building envelope are often insidious in nature – what starts as just a small gap in sealant, poorly detailed flashing, or a hairline crack likely won’t stay that way for long.

Whether it enters after damage from a torrential storm or via a gradual leak, moisture will slowly compromise building materials over time. Once this damage is visible, the underlying issue may have spread well beyond its original source, turning a once simple repair into a much larger and more expensive problem.

It’s a pattern Pretium engineers specializing in building and structural restoration see time and time again during building envelope investigations.

Luckily, water damage isn’t inevitable. We have strategies for designing, inspecting and maintaining building envelopes and moisture barriers in ways that dramatically reduce the risk of long-term deterioration and structure-wide damage.

Design buildings assuming water will want to get in

Water doesn’t always behave the way we expect. It doesn’t play by the rules of gravity and just drip down – in its various forms, water can move horizontally along structural members, rise through capillary action, wick through porous materials and follow concealed pathways.

That’s why successful building envelope design starts with the assumption that water will eventually find a way in.

Rather than relying on a single barrier to keep a building dry forever, resilient building envelopes use multiple strategies to keep interiors dry.

Use multiple means of resistance and layers of defence

No single building envelope component can completely keep water leaks at bay.

Flashings, drainage planes, air and water barriers, rainscreens, sealants, and carefully detailed transitions all work in tandem to protect buildings from moisture intrusion.

This layered approach creates redundancy throughout the assembly, so if one component becomes compromised, others will continue to protect more vulnerable building materials. While water typically follows the path of least resistance, that path can shift with wind pressure, temperature, building movement, and changes in material properties.

Once moisture reaches the building structure, the impacts will vary by material. Wood can rot, steel can corrode, freeze-thaw cycles can accelerate deterioration and prolonged dampness will create ideal conditions for mould growth.

Inspect defense layers often to monitor for potential water issues

Even the best-designed building envelope requires regular attention as components age, drainage paths get blocked, and buildings shift over time, creating new opportunities for water intrusion.

That’s why routine inspections are essential. At minimum, buildings should be reviewed once a year, ideally before and/or after winter, when freeze–thaw cycles and snow loads tend to expose vulnerabilities or accelerate existing wear.

If an inspection identifies signs of a leak, or if occupants report recurring leaks, it’s important to complete a full building envelope investigation. Identifying the true source of a leak early can significantly reduce the extent and cost of future repairs.

There’s a saying in building science that “the devil is in the details,” and nowhere is that more evident than during a leak investigation. Water rarely behaves in a straightforward way once it enters an assembly, often travelling along hidden interfaces and structural elements before revealing itself. Being able to think like water can help engineers uncover the source of a leak so they can recommend repairs.

Carry out building envelope repairs without delay

Once moisture enters a building assembly, deterioration can continue until the problem is addressed, weakening materials, spreading damage to adjacent components, and escalating repair costs.

Addressing deficiencies as soon as they’re identified is one of the most effective ways to protect both the building envelope and the long-term value of the asset.

Water will always look for a way in, but with thoughtful design, multiple layers of defence, routine inspections and timely repairs, building owners can prevent existing minor moisture issues from ballooning into major building failures.

Financial Resilience Through Reserve Fund Studies

Assessment and Capital Planning

Partner with Qualified Building Consultants to Strengthen Your Reserve Fund Planning

For condominium owners and board members in Ontario, a Reserve Fund Study (RFS) is about more than just financial forecasting; it is a legislated requirement and a cornerstone of responsible building management. Properly conducted, it provides the roadmap for sustaining your property’s long-term financial health while protecting owners from unexpected costs.

What is a Reserve Fund?

A condominium’s reserve fund is a dedicated account used exclusively for major repairs and replacements of common building elements. Each unit owner contributes through their monthly condo fees, creating a collective financial safety net.

By engaging a qualified consultant with expertise in both financial forecasting and building science, condominium corporations can ensure that their RFS is accurate, comprehensive, and tailored to their building’s unique needs. This protects the property and gives peace of mind to every owner.

What Does a Reserve Fund Study Include?

A Reserve Fund Study covers all major common condominium elements, including roofing systems, windows, cladding, elevators, HVAC, electrical, plumbing and parking structures. Each component is assessed for its current condition relative to its expected life cycle and projected repair and replacement costs are prepared.

In addition to the physical condition assessment of the building elements, condo corporation’s governing documents, financial records, and various legal agreements are also reviewed. This information is combined into a 30-year financial plan that accounts for inflation and potential market volatility, allowing boards to budget and plan strategically.

This planning approach helps minimize the risk of Special Assessments and Emergency Loans. This can protect the owners from sudden financial shocks and high borrowing costs for urgent and essential repairs.

Reserve Fund Studies are legally required for every condominium corporation.

Legal Requirements in Ontario

Under Section 94 of the Ontario Condominium Act, 1998, Reserve Fund Studies are legally required for every condominium corporation, whether they are residential, commercial, industrial or mixed-use.

There are 3 classes of RFS:

  • Class 1: A comprehensive baseline study which includes a physical inspection of the property, document review to verify corporation records, and interviews with the corporation’s representatives.
  • Class 2: An update to Class 1 study which includes a site visit and is completed every six years.
  • Class 3: A study without a site visit to update financial forecasts, which must be completed every three years between Class 2 updates.

Regardless of the class, all studies must be carried out by qualified professionals, such as licensed engineers or other regulated building professionals.

Why Reserve Fund Studies Matter

Beyond legal compliance, a well-planned RFS offers significant benefits:

  • Stable condo fees: By balancing adequacy and affordability, corporations can meet long-term obligations without overburdening owners in the present.
  • Enhanced property value: A healthy reserve fund improves a condominium’s marketability, appealing to buyers, lenders, and insurers.
  • Stronger community trust: Transparent planning fosters accountability, ensuring boards act in the best interest of owners.

The Pretium Advantage

At Pretium Engineering, we combine our engineers’ and technologists’ expertise across service areas to deliver Reserve Fund Studies that are both technically rigorous and financially precise. This multidisciplinary approach to RFS ensures that projections remain realistic and funding plans are sustainable. We also work directly with the Property Managers and the Boards to ensure our recommended plan aligns with their goals.

Conclusion

A Reserve Fund Study is not just a regulatory requirement; it is a vital planning tool that safeguards your property, your investment, and your community. By partnering with experienced professionals like Pretium, condominium corporations can confidently prepare for the future and ensure financial stability for decades to come.

Multi-Disciplinary Engineering Teams: Why It’s Always Better When We’re Working Together

Energy and Carbon Reduction

How a Multi-Disciplinary Engineering Team Helps Deliver Successful Projects

When a building owner sets ambitious goals—like cutting energy consumption by more than 50% and reducing greenhouse gas emissions by 85%—those results don’t happen by chance. They require a team of specialists, like a multi-disciplinary engineering team, working side by side, who can tackle every angle of a complex retrofit in-house.

The Power of a Multi-Disciplinary Engineering Team

At Pretium Engineering, we bring mechanical, electrical, structural, building envelope, and energy modelling expertise under one roof. This breadth of capability makes us a true one-stop shop for engineering needs—whether it’s restoration, deep energy retrofits, or new construction.

Instead of juggling multiple firms and consultants, our clients benefit from seamless collaboration. When our teams work together from the outset, we’re able to:

  1. Streamline Project Delivery
    With all disciplines in-house, communication is direct and ongoing. This avoids the delays of coordinating across external consultants and keeps projects moving smoothly from concept to construction.
  2. Reduce Surprises and Extra Costs
    Our engineers share a common understanding of the project scope, so design conflicts are resolved early—before they lead to costly change orders during construction.
  3. Deliver Better Long-Term Performance
    By coordinating envelope and mechanical solutions alongside structural and electrical considerations, we design strategies that improve durability, optimize efficiency, and meet evolving performance standards such as Passive House, B19, and Energy and Water Reporting and Benchmarking requirements.

Simply put, our multi-disciplinary engineering team’s approach means fewer gaps, fewer headaches, and better outcomes.

Case Study: 71 Sanford Avenue, Hamilton

A strong example of Pretium’s multi-disciplinary approach is the deep energy retrofit underway at 71 Sanford Avenue North.

A strong example of Pretium’s multi-disciplinary approach is the deep energy retrofit underway at 71 Sanford Avenue North, a six-storey, 57-unit non-profit housing complex built in 1993. In addition to the residential units (six one-bedroom and 51 two-bedroom suites), the ground floor includes 10 assisted-living rooms leased and operated by others. The building’s total area is approximately 69,500 ft² (6,450 m²), excluding the underground parking garage. Major mechanical systems—including heating boilers, domestic hot water boilers, and a make-up air unit—are housed in a rooftop penthouse, with additional mechanical and electrical spaces located in the basement.

For this project, our team began with a detailed review of all drawings and design documents. Using the IES Virtual Environment software platform, our in-house energy modellers developed a comprehensive whole-building energy model to evaluate a range of energy conservation measures (ECMs). The goal was to identify a package of measures that would achieve the Canada Greener Affordable Housing (CGAH) program requirements: a 70% reduction in site energy use and an 80% reduction in GHG emissions, relative to pre-retrofit performance.

Once a compliant retrofit package was established, Pretium prepared full design and bid documents for the proposed measures. Our role continues beyond design: we are now providing contract administration and construction review services for the construction/implementation of all scopes, ensuring quality and performance are maintained from concept to completion.

Building Better Together

Deep energy retrofits are some of the most technically challenging projects in our industry. Success depends on collaboration across disciplines and a unified strategy from start to finish.

At Pretium, we don’t just coordinate between specialties—we integrate them under one roof. This gives our clients peace of mind, knowing they have a single, multi-disciplinary engineering team managing their project with the technical depth, problem-solving capacity, and accountability needed to deliver exceptional results.

Because in the end, it’s always better when we’re working together.
