4 Reasons Why DIY Window Caulking Often Fails

Caulking DIY jobs fail fast. If the caulking is not done right then you might get leaks, drafts and even mold.

Mississauga weather changes a lot so proper window sealing is very important. Let’s look at four common DIY mistakes and how to get perfect window sealing in Mississauga.

  1. Using the wrong caulk

Many DIYers grab the first tube they see but the wrong caulk will not last. Cheap acrylic caulk cracks and peels in bad weather. Silicone or polyurethane caulk stays strong in rain and snow. Use high-quality exterior caulk that’s made for windows.

  1. Not cleaning the surface first

Caulk needs a clean surface to stick. New seal will not last if there is dirt, dust, or old caulk. Scrape off old caulk and cleaning with rubbing alcohol.

  1. Applying thick or thin messy lines

Too much caulk makes a big mess and too little will not seal properly. If you cannot apply an even bead of caulk then leave it to the experts. They have steady hands and the right tools to avoid weak or messy caulk lines.

  1. Caulking in bad weather

Mississauga has cold winters and humid summers. If you caulk on a rainy, cold or hot day then it will not dry properly. A dry mild day is the best for caulking so always check the weather before you start caulking.
