Stop drafts, water leaks, and energy loss with professional weather sealing solutions. Our premium weatherstripping and threshold seals protect your garage from harsh Ontario winters, humid summers, and everything in between.

Watch for these warning signs that your weather seals need immediate replacement.
Feel cold air entering around door edges even when closed. Temperature differences of 10Β°C+ between garage and outdoors indicate seal failure.
Puddles forming after rain or snow melt under the door. Water infiltration damages stored items and promotes dangerous mold growth.
Heating costs increasing due to poor garage insulation. An unsealed garage can increase home heating costs by 15-30% during winter months.
Daylight visible around door edges, cracked rubber seals, or compressed weatherstripping that no longer springs back to shape.
If you notice any of these issues, your weather seals are compromised and costing you money every day. Our technicians can assess and fix the problem in a single visit.
Proper sealing can reduce heat loss by up to 71%, saving GTA homeowners $200-400 annually on heating costs.
Our seals keep moisture out, preserving your garage contents and indoor air quality.
Compression seals dampen street noise, traffic sounds, and neighborhood activity.
Tight seals prevent mice, insects, leaves, and snow from entering your garage. Keep your space clean and prevent the damage rodents cause to wiring and insulation.
An unsealed garage door can allow up to 10,000 cubic feet of cold air infiltration per day during winter monthsβequivalent to leaving a window open 24/7.
Our weatherproofing solutions are specifically selected to withstand the unique challenges of Canadian weather patterns across Mississauga, Toronto, and the GTA.
With temperatures dropping to -30Β°C, inferior seals crack and fail. Our EPDM rubber maintains flexibility to -50Β°C and resists ice adhesion.
July humidity levels cause cheap vinyl to warp and lose shape. Our UV-stabilized materials resist swelling and maintain compression seal year-round.
Ontario's frequent temperature fluctuations create expansion stress. Our aluminum retainers and flexible seals accommodate movement without tearing.
Proper installation is critical for effective sealing. Our meticulous approach ensures lasting performance.
We measure gaps at multiple points, identifying uneven concrete, warped panels, and structural issues.
Old sealant and debris removed. Surfaces cleaned and treated for proper adhesion.
Materials cut and fitted on-site for your specific door dimensions and irregularities.
Seal compression verified using smoke tests. Door operation checked for binding.
Why we refuse to use cheap hardware store products that fail within months.

When garage door weather stripping fails causing drafts, pest intrusion, and noise transmission, Vertex provides complete EPDM rubber and vinyl seal replacement for sectional, roll-up, and carriage-house door configurations.
We install bottom astragal seals, kerf-style side seals, threshold ramps, jamb seals, and header seals that block GTA ice dams, wind-driven precipitation, and airborne contaminants while dramatically improving insulation value.
Frame deterioration and rust damage become visible during seal removal. Professional compression-fit installation lasts years versus DIY attempts developing gaps within months.Β
Energy savings typically pay for complete service within first winter through eliminated air infiltration and enhanced thermal performance.
