Maintaining a healthy building envelope is one of the most important things you can do for your condominium, whether it’s a townhome or a high-rise. It’s estimated that 90 per cent of air and water leakage occurs at just one per cent of a building’s sealant locations, which are vulnerable sites like terminations, transitions, and penetrations. So it’s crucial to ensure that this one per cent is properly sealed.

Exterior sealants are an essential part of a building envelope, but they are often not well understood or maintained. This is because they are out of sight and, therefore, out of mind. This is especially true for high-rise condominiums, where much of the sealant is not visible from the ground.

Caulking and sealants are important for protecting a building from water damage, but they need to be replaced every 12 to 20 years. If a condominium doesn’t have a regular replacement schedule, the caulking and sealants may degrade and cause water damage.

In short, a sealant replacement project can be a big undertaking. But with the right planning and execution, it can also be a smooth and successful one. Here are essential tips to get you started:

Check the Caulking

Inspect the caulking around windows, doors, and other openings. If cracks or gaps are present, water may be able to enter the building. 

Confirm Possible Over-Beading

To determine if a site needs to have all of the old sealant removed or if over-beading is an option, you need to determine if the site has been over-beaded before. If it has, then complete removal is required. If not, then over-beading on failing to caulk is an economical option.

Use a Top-Quality Sealant

The type of sealant in use will determine how long it will last. If an inferior product is used, it will not last as long.

Ensure Team Coordination

It is vital to ensure that everyone involved in the project understands the proposed sealant system and any potential limitations. This will help to avoid any issues during or after the project.

Choosing a Contractor

It’s crucial to find a contractor who is qualified and trustworthy to do your sealant replacement. The contractor’s warranty will only cover a small part of the sealant’s expected lifespan, so it’s crucial to find someone reliable. 

Make sure also to ask to see the contractor’s health and safety plan. High-rise sealant replacement projects require specialised health and safety expertise and management.

Don’t choose a contractor based on price alone–you may end up paying more in the long run if they don’t do a good job. Sealant systems should last 12 to 20 years, so choose one that will save you money in the long term, not just the short term.

Conclusion

Sealants are a small but important part of building construction. They help keep water and other elements out of a building, protecting the structure from damage.

Replacing exterior sealants is an integral part of maintaining your home. Doing so can prevent water damage, drafts, and energy loss. When choosing a sealant, be sure to pick one that is weather-resistant and compatible with your home’s material. With a bit of research, you can find the perfect sealant for your needs.
