The exterior “envelope” of your building depends on caulking or sealants to fill the gaps and joints and protect your building exterior against water and air penetration. While sealants are a small detail on your building exterior, their deterioration and failure can lead to large problems, including water ingress and building damage.
We can help protect your building. Our sealant renewal projects include removal and replacement of sealants on metal, concrete and wood building components on strata apartments, townhomes, and high-rises. Often we replace sealant in conjunction with other work on the building such as concrete restoration, painting, waterproofing, or balcony membranes.
We’re experienced at applying single and two-component polyurethane sealants, as well as the installation of Dow Corning’s 123 silicon-seal strip system. Our knowledge and commitment to customer service means that we can complete your sealant renewal project efficiently and cost-effectively.
The exterior “envelope” of your building depends on sealants (sometimes referred to as caulking) to fill the gaps and joints and protect your building exterior against water and air penetration. While sealants are a small detail on your building exterior, their deterioration and failure can lead to larger problems, including water ingress, thermal leakage, and building damage.
A sealant or caulking joint bonds together two substrates – for example, an aluminum window frame to a concrete wall, or the “cold joint” between two concrete panels – in order to block the movement of water or air through the building envelope. As the different components of the structure expand and contract (due to changes in season and temperature), the sealant needs to remain flexible and move along with them.
Over time, sealant loses its flexibility and adhesive properties. A single-component urethane sealant will typically last 10-20 years, depending on a number of factors – including its environment, the amount of movement it experiences, and how much sunlight exposure it receives.
Joint sealants, like other building envelope components, do not have an unlimited service life. If sealant joints are permitted to deteriorate or fail, the building envelope will be compromised, leading to water ingress, heat/cooling loss, and further building deterioration.
It may be worthwhile to consult a building consultant or envelope engineer to determine your building sealant repair needs. We can also visit your building and provide some advice based on our visual review.

Staff were always very friendly and helpful. Very accommodating and flexible. Kevin and crew were fantastic. Justin was fantastic. Remdal did a great job! March 2023
The crew has been all smiles, accommodating, polite, friendly, and clearly communicative. The crew was very conscious of locking doors, leaving everything tidy and tucked away. Communication with Kaveh, Staven, Jeff, Nima, and the whole crew has been FANTASTIC! The guys have been great to deal with and it is much appreciated. December 2022
The Remdal employees were a pleasure to deal with & adhered to all our stringent safety policies. As the work was on all Canada line stations, it was essential that the site was clean, tidy & safe for public to enter. Very professional in all aspects. I would certainly recommend Remdal to any client & retain their services for any future projects. January 2023
From the beginning the Remdal Crew were polite, clean, efficient, and professional. Great team! We had bi-weekly meetings and any questions that arose outside of those meetings were answered promptly. Great job! The building looks so much better, and your flexibility to look at issues outside of scope, was appreciated. The Remdal Team worked hard to complete the job on time. As you know we had options when it came to awarding the project. Remdal was our clear first choice once we read through their proposal. December 2022
