Whitby's trusted choice for replacing failed window thermal units and maintaining heavy-duty commercial door hardware.
Lake Ontario humidity causes window seals to fail, leading to foggy glass. We replace the insulated glass unit (IGU) while preserving your valuable frames.
For historic homes in Downtown Whitby, we retrofit modern energy-efficient glass into older frames and replace vintage window cranks and hardware.
A stuck patio door is a major frustration. We replace crushed or rusted rollers with premium steel assemblies, making heavy glass glide effortlessly.
We also realign front entry doors that have shifted due to settling in newer Brooklin builds, adjusting hinges so deadbolts lock smoothly.
Strong winds off Lake Ontario push cold air through degraded seals. We remove cracked exterior caulking and apply premium sealants.
Replacing flattened weatherstripping on doors and windows is the fastest way to improve comfort and protect your homeโs energy efficiency.
Upgrade your homeโs aesthetic and security with premium handlesets, deadbolts, and properly adjusted multi-point locks.
For businesses in Whitby, we repair commercial aluminum door closers, pivots, and panic bars to ensure reliable access.
We supply and install custom replacement glass for shattered patio doors, decorative sidelites, and commercial storefront windows.
All installations meet strict building codes, using safety-tempered or laminated glass to keep your property secure.
Accidents or severe lake storms can break glass and expose your property. Our Whitby emergency team is available 24/7.
We board up the damage securely, clean up the hazard, and immediately process the order for your permanent replacement glass.

Advice shaped by higher traffic entries, condo exposures and emergency securing calls we handle in Whitby.
Whitby homes closer to the waterfront often collect more moisture on south-facing glass, especially after freeze-thaw cycles. If you notice repeat condensation or staining around the stops, we can inspect the seal package and replace only the failed unit before the sash starts to deteriorate.
For busy shops in Whitby, a door that slams or refuses to close fully wastes heat and leaves a bad impression on customers. We carry heavy-duty commercial hydraulic closers and can tune the sweep and latch speeds properly for the storefront.
Many Whitby homeowners are surprised to learn they do not need to replace every window just because a few have turned foggy. By replacing only the failed insulated glass units, we restore clarity and efficiency for a fraction of a full-house replacement.
From Brooklin subdivisions to Port Whitby commercial centers, we are your local specialists. We specialize in full-scale window replacements and intricate commercial door closer repairs. Our transparent pricing and meticulous cleanup make us the go-to choice for property managers and homeowners alike.
Whitbyโs blend of lakefront exposure, historic districts, and new sprawl dictates our repair strategies.
Historic homes require delicate wood frame adjustments and specialized glass retrofitting to maintain their original aesthetic.
Rapidly built subdivisions in Brooklin often see foundation shifts, causing entry doors to misalign and stick against their frames.
Homes closer to the lake deal with high moisture, which accelerates thermal seal failure and rusts standard patio door rollers.
Properties facing the lake suffer from severe wind washing. Premium caulking and draft-stopping are essential for winter comfort.
