At Fentec, installation isn’t just a service — it’s what we do best. We’re certified general contractors who focus solely on windows and doors. No flooring, no drywall, no distractions. Just expert installations done with precision, care, and lasting results. We serve the Greater Montreal area with a full range of services tailored to residential and light commercial projects. Whether you’re a homeowner refreshing outdated windows or a contractor managing a multi-unit build, our process is clean, efficient, and built around your peace of mind.

Window Installation

All materials. All brands. All configurations. Installed with care. From traditional sliders to high-performance tilt-and-turn windows, we install every type of window with the same attention to detail. Our team is trained to handle basic upgrades, oversized glass units, and everything in between.

What we install:

Already have your windows? We’ll install them — no matter the brand and origin

We install all types of windows with expert technique and attention to detail. From sliders to triple-pane tilt-and-turns, every installation follows our proven method.
We use proper levelling, membranes, shims, insulation foam, and sealant protocols — all in accordance with CSA-A440 standards — to ensure your windows are energy-efficient, weather-tight, and built to last.

Door Installation

Entry doors, patio doors, interior or oversized — we’ve got it covered. Your doors are more than functional — they protect your home, shape first impressions, and define comfort. At Fentec, we treat every door like it matters.

What we install:

Whether it’s a renovation or a new build, we manage everything from measurements to finishing trim.

We follow strict installation protocols — including proper leveling, weatherproofing, insulation, and sealant application — in line with CSA-A440 standards where applicable, to ensure long-term performance and durability.

Complex & Oversized Installations

Big glass? Tight timelines? Hard-to-access walls? Bring it on.

We’re fully equipped for complex jobs — and not every installer is. Whether you need a massive triple-pane window lifted by crane, or you’re dealing with a tight opening in an old masonry wall, we have the training, gear, and experience to make it happen.
