Trusted With the Doors and Windows of Newmarket
A property is only as secure as its weakest opening. Windows & Doors Newmarket makes sure that opening is not yours, working across Newmarket on entry doors, sliding patio units, sash and casement windows, commercial glazing, and access control systems.
Residential or commercial, the process is the same: inspect, explain, quote, then do the work exactly as described.
Security Checked on Every Visit
While we are there we test the locks, frames, and strike plates, whether or not that was the reason we came.
Same-Day Slots Held Open
We keep capacity in the schedule for urgent calls rather than booking every hour weeks ahead.
One Price, Explained
Every line on the quote gets a plain-English reason. If you do not want a line, it comes off.
Parts With a Paper Trail
We note what was fitted and where, so future service is not a guessing game.
The Return on New Windows and Doors
Four measurable improvements, all of which start the day the installation is finished.
Efficiency You Can Measure
Low-emissivity coatings and inert gas fills reflect heat back inside instead of letting it pass through the glass.
Equity You Keep
Window and door replacement remains one of the most reliably recovered renovation costs at the point of sale.
Protection That Holds Up
Modern materials shrug off the rot, warping, and swelling that turn an older frame into a weak point.
Steadier Indoor Temperatures
Rooms stop swinging between too cold and too warm, because the envelope finally holds what the system produces.

Windows Specified for the Weather We Actually Get
Reinforced Against Movement
A galvanised steel core handles the expansion and contraction that comes with wide temperature swings, so the frame does not distort over the years.

What Our Clients Report Back
The front door at our place near Glenway would only lock if you leaned on it. Windows & Doors Newmarket corrected the frame alignment and it locks with one finger now.
Our bedroom windows around Armitage were fogged and draughty. Both replaced in one visit and the room is noticeably warmer.
A break-in attempt damaged the rear door at our shop over by Bristol-London. Secured the same night, reinforced frame and new lock fitted the next day.
The sliding door at our place just off Gorham-College Manor was grinding along the track. Rollers replaced and the track cleared. Silent again.
I managed to lock my keys in the house out toward Huron Heights twice in a month. They were quick both times and did not charge me more the second time.
We replaced our old entry door at the house near Stonehaven with an insulated one. The draught in the hallway has completely disappeared.
Our unit around Summerhill Estates needed keypad entry for cleaners and contractors. Set up so we can issue and cancel codes without calling anyone.
The storm door over by Central Newmarket had a closer that had given up entirely. New closer, adjusted properly, and it shuts gently now.
Our stairwell window just off Woodland Hill was cracked from top to bottom. Replaced within days and the new glass is a better spec than the old.
The back door lock out toward Quaker Hill had worn out. Replaced with a properly rated cylinder and rekeyed to match the front. One key now.

Straight Answers to Common Questions
Most standard vinyl windows in Newmarket 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 Newmarket 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 Newmarket 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 Newmarket 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 Newmarket 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 Newmarket 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 Newmarket 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.
