Frequently Asked Questions

Do you remove the old caulking first?

Yes, absolutely. We cut out and scrape away the old, failed sealant to ensure the new material adheres directly to the building surface for a watertight bond.

How long does the new caulking last?

We use high-performance polyurethane or silicone sealants rated for 15-20 years. These materials are flexible, meaning they won't crack when your home expands and contracts during Toronto's freeze-thaw cycles.

Can you match the color of my window frames?

Yes. We carry a wide range of professional sealant colors (white, black, beige, brown, grey) to match your aluminum, vinyl, or wood frames perfectly for a seamless look.

Area to Cover

Why is a Technical Visit necessary?

Exterior caulking isn't just about applying new product; it's about preparation and access. Applying new caulk over old, dirty sealant guarantees failure within months. Our Window & Door Exterior Caulking & Sealing assessment checks the condition of the substrate for rot, measures the gap width (to see if "backer rod" filler is needed), and determines the safest access method for second-story windows.
