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.

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.
