Window caulking is installed in new windows, to keep the elements out. Over time, with house settling, this joint is often broken and a failed caulking seal allows water into your home, as well as air and heat (and cooling) loss, costing you money, and risking the integrity of your home and your windows.

At WindowFix.ca, we offer full exterior window caulking services that are second to none. Our qualified professional caulking technicians first remove all the original exterior caulking (where appropriate), and then they prep the surface and fill in any obvious voids in the space with foam backer rod prior to caulking in a commercial grade sealant. We tool the caulking to a neat and clean finish, to ensure a full strength bond. All caulking projects come with our 10 year labour warranty and the material is warrantied for 20 years.

With new caulking, your windows will be properly sealed from the elements.  Many of our clients comment on how much quieter (and warmer in winter) their home is after having their caulking replaced.  The new caulking (along with the additional insulation that we provide in behind the window frames) significantly reduces excess moisture that appears on windows during extreme cold temperatures as well.
