Door, Window & Lock Services in Oakville

A typical eight to ten window home is one to two days on site, and a single entry door is a half day. We take out, fit and seal one opening at a time rather than stripping the whole house at once, so your home is never standing open and you can carry on around us. Custom sizes and special-order glass add 3 to 6 weeks before the install day, and you get that date when you order rather than when you chase us for it.

No. Windows & Doors Oakville measures and quotes at no cost and with nothing attached to it. A full house takes about 45 minutes: we check every opening, look at the frames and sills for rot or water damage, and tell you what genuinely needs replacing against what has years left in it. The written quote reaches you the same week, itemised opening by opening rather than as a single number.

Every window we fit meets or beats the ENERGY STAR requirement for this climate zone, with low-E coated, argon-filled sealed units as the standard rather than an upgrade you pay extra for. On a Oakville home replacing single pane or failed double glazing, most people notice the difference first in the draughts and the cold spots near the glass rather than on the bill. If your existing windows are still sound we will say so.

Our installation workmanship carries a 10 year warranty and Windows & Doors Oakville honours it regardless of which of our crews did the original fitting. The windows themselves keep their manufacturer warranty, which on the sealed units and vinyl frames runs 20 years to lifetime depending on the line you pick. If a seal fails inside that period we handle the claim with the manufacturer ourselves instead of handing you a phone number.

Yes, and we do it right through the Oakville winter. Each opening is out, in and sealed inside about an hour, so the house never drops more than a degree or two, and we work one room at a time with the rest of the home closed off. The foams and sealants we use are rated for cold weather installation. If the temperature or the wind makes it genuinely unsafe we move your date rather than push through it.

We remove and dispose of every old window and door, vacuum the work area and haul the debris away the same day — that is included, not a line added at the end. A straight replacement in an existing opening needs no permit in most Oakville municipalities. If the project changes the size of an opening or cuts a new one then a permit is required, and we prepare the drawings and file the application for you.

Windows & Doors Oakville carries full liability insurance and WSIB coverage, and we will send the certificates before any work starts if you would like them on file. Our own installers do the work — booked jobs are never passed to a subcontracted crew you have never met — and the person who quoted your job is there on the day. They walk every opening with you before packing up and show you how each new unit operates and locks.
