The Science of Sealing: Why Caulking Matters in Ottawa
Window caulking is not merely an aesthetic choice; it is a critical component of your home's structural health. In Ottawa's distinct climate zone, building materials expand and contract significantly. If your caulking is rigid, cracked, or outdated, this movement creates micro-gaps.
These gaps lead to three major issues:
- Thermal Bridging & Energy Loss: Air leakage accounts for up to 30% of a home's energy loss. Proper sealing stops cold drafts in winter and keeps humidity out in summer, lowering your HVAC load.
- Water Infiltration & Mold: Even small cracks can allow water to wick into your wall assembly. Over time, this causes wood rot, insulation damage, and mold growth that can affect air quality.
- Pest Intrusion: Unsealed gaps are open invitations for ants, spiders, and other pests seeking warmth during the cooler months.
Our Specialized Caulking Services
Window Caulking
Proper window caulking is crucial for maintaining the energy efficiency and weatherproofing of your property. Our team uses high-quality silicone and polyurethane materials to seal gaps and cracks, creating a flexible barrier that moves with your home.
Exterior Caulking
Exterior caulking protects your property from the harsh Ottawa weather. Our Ottawa exterior caulking services cover siding, trim, doors, and vents, ensuring that your entire building envelope is defended against the elements.
Commercial Caulking
We offer specialized caulking services for commercial properties. From high-rise control joints to storefront glazing, our team understands the unique needs of commercial buildings and provides tailored solutions to ensure longevity.
Our 8-Step Professional Caulking Process
Quality caulking is 80% preparation and 20% application. Many DIY attempts fail because they skip the critical preparation stages. Here is the rigorous process we follow to ensure a bond that lasts 15+ years:
- Site Inspection & Assessment We begin by inspecting all windows, doors, and penetrations to identify failure points and choose the correct sealant for your specific substrate (brick, stucco, vinyl, or wood).
- Old Sealant Removal We do not caulk over old caulk. We mechanically remove the old, degraded sealant to expose the original frame and siding surfaces.
- Debris Cleaning Using brushes and air blowers, we remove dust, mildew, and loose particles. A clean surface is vital for chemical adhesion.
- Solvent Wipe We apply an industrial-grade solvent to strip away remaining oils, oxidation, or silicone residue, ensuring a sterile bonding surface.
- Backer Rod Installation For gaps wider than 1/4 inch, we insert a closed-cell foam backer rod. This prevents "three-point adhesion" (which causes tearing) and provides insulation depth.
- Sealant Application Using professional-grade bulk guns, we apply a generous, continuous bead of commercial-grade sealant (typically high-modulus silicone or polyurethane).
- Professional Tooling This is the "art" of caulking. We tool (smooth) the bead using specialized spatulas to press the material into the gap, eliminating air pockets and creating an aesthetically pleasing, concave finish.
- Final Cleanup & Inspection We clean up all debris and perform a final walk-around to ensure every inch is sealed to our high standards.
Material Selection: Choosing the Right Sealant
Not all caulks are created equal. Hardware store acrylic latex often cracks within two winters. We exclusively use industrial-grade sealants tailored to your home's needs.
| Material Type | Best Used For | Lifespan | Key Advantage |
|---|---|---|---|
| 100% Silicone | Glass, Metal, Non-porous surfaces | 20+ Years | Extreme UV resistance and permanent flexibility; does not shrink. |
| Polyurethane | Concrete, Brick, Wood (Porous) | 10-20 Years | Superior adhesion to masonry; paintable (unlike silicone). |
| Hybrid Polymer | High-movement joints | 15+ Years | Combines the strength of polyurethane with the weathering of silicone. |
| Acrylic Latex | Interiors only | 5-10 Years | Easy cleanup and low odor, but poor freeze/thaw resistance for exteriors. |
*Note: Our technicians will select the specific compound based on your home's cladding material (e.g., Brick vs. Vinyl Siding) to ensure chemical compatibility.

Frequently Asked Questions About Window Caulking
The ideal season for exterior caulking in Ottawa is between late spring and early autumn (May to October). Surfaces need to be dry and temperatures should generally be above 5°C (40°F) for the sealant to cure properly, though we utilize specialized low-temperature sealants for emergency repairs.
Look for these signs: dried, cracked, or shrinking caulk; drafts felt around the window frame; high energy bills; or visible gaps between the window frame and the siding/brick. If the caulk is peeling off in strips, it has lost its adhesion and needs immediate replacement.
No. Applying new caulk over old caulk is a temporary band-aid solution that rarely lasts. The new layer will not adhere to the dirty, oxidized surface of the old layer. For a lasting seal, the old material must be fully removed and the surface cleaned.
According to energy efficiency studies, sealing air leaks can reduce heating and cooling costs by an average of 15% to 20%. In a climate like Ottawa's, this return on investment is often realized within 2 to 3 years.
