Doors That Close and Windows That Seal, Right Across Mississauga
Two things should be true of every opening in a building: it should close without a fight, and it should keep the weather where it belongs. Windows & Doors Mississauga restores both for properties across Mississauga through door repair, window installation, glass replacement, and locksmith services.
You will get a clear explanation of what failed and why, which usually costs less to fix than most people expect.
Explanations You Can Follow
No jargon and no vague warnings. We show you the worn part and what it is doing to the rest.
Emergency Cover That Answers
Our after-hours line reaches a technician, not a message service that calls back on Monday.
Firm Pricing From the Outset
The estimate is a commitment. Extra work needs your approval before it happens.
Warranty That Means Something
A guarantee is only useful if someone answers when you use it. Ours is honoured without argument.
Why an Upgrade Pays for Itself
Replacement windows and doors are one of the few home improvements that keep returning money after the work is finished.
Lower Running Costs
Every degree your heating no longer has to replace is money that stays with you. Modern glazing keeps a lot of them.
A Better Appraisal
New openings read as a maintained property, and maintained properties consistently appraise and sell above the alternative.
Real Physical Security
Modern hardware resists forcing in ways that a worn latch on a softened frame simply cannot.
Less Noise, Fewer Draughts
A continuous seal around the sash is what stops both, and it is exactly what an aged unit has lost.
Full-Service Work in Mississauga
Door Repair
Most door faults are alignment rather than damage, and replacing the door fixes nothing if the frame moved. Property owners in Mississauga use Windows & Doors Mississauga for door repair, covering diagnosis, hinges, latches, frames, and weather seals.
Door Replacement
Swapping a door without addressing the threshold and seals just moves the draught somewhere else. Property owners in Mississauga use Windows & Doors Mississauga for door replacement, covering measurement, removal, fitting, thresholds, and weather seals.
New Door Installation
Putting a door where none existed means framing, headers, and finishes, not just the door itself. Property owners in Mississauga use Windows & Doors Mississauga for new door installation, covering framing, headers, fitting, trim, and making good.
Window Repair
Most windows written off as needing replacement need hardware and seals instead. Homeowners in Mississauga use Windows & Doors Mississauga for window repair, covering hinges, handles, gaskets, glazing units, and honest replacement advice.
Window Replacement
Replacement is worth it when the frame has gone; before that it is usually money spent early. Homeowners in Mississauga use Windows & Doors Mississauga for window replacement, covering survey, removal, fitting, insulation, sealing, and finishing.
New Window Installation
Cutting a new opening is structural work before it is glazing work, and the lintel comes first. Property owners in Mississauga use Windows & Doors Mississauga for new window installation, covering lintels, opening formation, fitting, and making good.

What the Neighbours Say
Our front door near Port Credit needed a shoulder to close. The frame had moved. Windows & Doors Mississauga corrected it properly instead of planing the door.
The upstairs windows around Streetsville would not stay open. New restrictors and serviced hinges, and they work as they should now.
Someone put a brick through the front glass at our shop over by Clarkson. Made safe within the hour and replaced with laminated glass.
The patio door at our house just off Lorne Park had a lock that never quite engaged. Adjusted the keeper and it locks solidly every time.
I was locked out of my place out toward Meadowvale in the rain. Fast response, non-destructive entry, and a spare key before he left.
We replaced six windows at our home near Erin Mills. Every one measured on site, fitted square, and sealed properly at the perimeter.
Our unit around Cooksville needed controlled entry for a shared entrance. Installed neatly and explained clearly so we can manage it ourselves.
The storm door over by Malton had a closer that slammed hard enough to shake the frame. Reset and it closes softly now.
Our side window just off Applewood had a cracked pane letting in cold air. Replaced quickly with a properly sealed unit.
The back deadbolt out toward Churchill Meadows would only turn halfway. Cylinder stripped, cleaned, and repinned. Perfect ever since.

Questions We Get Asked Most
Most standard vinyl windows in Mississauga land between $650 and $1,400 installed, and the three things that move the number are the size of the opening, whether it is a slider or a casement, and the glass package you choose. A bay or bow window is its own quote and usually runs $2,200 to $4,500. We measure every opening and price it as its own line, so you can see exactly what adding or dropping one does to the total.
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 Mississauga 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 Mississauga 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 Mississauga 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 Mississauga 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 Mississauga 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 Mississauga 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.
