Learn More →Window & Door Caulking and Recaulking
Cracked, peeling or poorly bonded sealant can leave gaps around frames. We review the affected joints and the adjoining surfaces before confirming the work.
Window Caulking & Recaulking
We replace failed exterior sealant around window perimeters and frame-to-wall joints. The work includes removing loose material where needed, preparing the surfaces and applying a new sealant line.
- Old caulk pulling away from the frame, brick or trim
- Cracked, uneven or layered previous repairs
- One affected window or several openings on the property
Exterior Door Frame Caulking
We seal exterior joints around door frames and surrounding trim where the old caulk has cracked, separated or worn away. The scope depends on the joint condition, adjoining surfaces and access.
- Exterior entry-door frame and trim joints
- Patio-door perimeter joints where the sealant needs replacement
- Selected commercial door and storefront frame joints
Door hardware, alignment and weatherstripping problems need a separate assessment.
How We Work
Our process focuses on proper prep, full joint coverage, and a clean finished line.
Step 1
Remove old silicone and clean the joint properly
We begin by cutting out failed silicone, scraping away remaining sealant, and clearing the joint so new material is not applied over weak or contaminated surfaces. This preparation stage matters because exterior window caulking lasts longer and bonds more reliably when the gap is clean, dry, and ready for new adhesion.
Step 2
Apply new silicone evenly to fill the full gap
Once the surface is prepared, we run a controlled bead of silicone between the window frame and the surrounding brick facade. The goal is full, even joint coverage with a consistent line that seals the opening, fills the visible gap, and supports better long-term resistance to water entry and seasonal movement.
Step 3
Finish the bead for a clean and professional result
The final step is shaping and refining the silicone line so it looks straight, uniform, and visually clean along the window perimeter. A properly finished joint is not only more presentable — it also creates a more complete seal between the window and facade, which is exactly what clients want from quality exterior re-caulking work in Toronto and the GTA.
