Expert glass installation solutions for modern and luxurious homes.
Most companies fix the break but ignore the seal. We specialise in precision home glass installation for indoor and outdoor areas with airtight integrity, eliminating drafts and preventing future fogging for good.
Beyond aesthetics, we prioritise structural integrity. Every project features our signature precision-fit technology and a reinforced seal guarantee, ensuring your custom glass remains leak-proof, crystal clear, and securely anchored for years.
Heir Glass designs and installs frameless, heavy-tempered glass enclosures tailored to your bathroom’s layout. Our moisture-tight sealing technology ensures a leak-proof finish that highlights your stonework while offering effortless, spot-free maintenance.
Transform your staircase with our ultra-clear glass railing systems. At Heir Glass, we specialise in standoff and base-shoe mounts that provide structural safety without blocking light, creating a seamless, high-end look for modern homes.
Enhance your deck or balcony with weather-resistant, wind-shielding glass panels. We use corrosion-proof hardware and safety-laminated glass to provide unobstructed views of your landscape while meeting all local Ontario building codes.
From floor-to-ceiling gym mirrors to elegant vanity features, we provide precision-cut glass with polished or bevelled edges. At Heir Glass, our expert mounting ensures a perfectly flush fit against any wall, even in older homes.
We build sophisticated home office partitions and sound-dampening glass walls. Our team installs custom-sized pivot or sliding doors that maximise natural light while providing the privacy and acoustic separation you need.
Frameless glass maximises natural light and open views to make any bathroom feel larger.

Most standard replacements, such as updating insulated units, can be completed in 1–2 hours once the glass is fabricated. For custom projects like frameless showers or railings, we provide a specific timeline following the initial design and measurement phase.
Yes. If your glass is cloudy or has moisture between the panes, we can often perform a glass-only replacement. This restores your thermal seal and visibility while keeping your existing frames intact, saving you high costs.
Absolutely. Heir Glass offers a Lifetime Seal Guarantee on our insulated glass units. This covers you against seal failure and moisture buildup, ensuring your windows remain clear and energy-efficient for as long as you own your home.
Yes. We use heavy-duty tempered safety glass that is significantly stronger than standard glass. In the rare event of a break, it crumbles into small, blunt pieces rather than sharp shards, making it the safest choice for busy families.
For interior railings, permits are usually not required for simple replacements. However, for exterior decks or major structural changes, a permit from the City of Markham may be necessary to ensure building code compliance. We can help guide you through this process.
Low-Emissivity (Low-E) glass has a microscopic coating that reflects heat. In Markham’s cold winters, it keeps heat inside; during humid GTA summers, it blocks solar heat from entering, drastically reducing your monthly energy bills.
Maintenance is simple. We recommend using a microfiber cloth and a non-ammonia glass cleaner. For shower doors, using a squeegee after each use prevents mineral buildup from Markham's hard water, keeping the glass like-new for years.
Yes. We prioritise urgent glass replacement needs for windows or doors that pose a security risk. Our team focuses on efficient, high-end installations to ensure your Markham home remains secure and aesthetically flawless.
