There is a version of this job that involves selling as many replacement units as possible, and a version that involves fixing what is fixable. Windows & Doors London has always worked the second way across London, handling door repair, window installation, and access control systems as the situation actually demands.
The result is a smaller invoice more often than not, and a customer who calls us again when something bigger goes wrong.
Plenty of units have years left in them. We tell you which yours are.
Emergency work is dispatched the same day, including evenings and weekends.
The written quote is the ceiling, not the opening bid.
Parts and labour both covered, with a clear term rather than vague reassurance.
Replacement is rarely about looks alone. These are the four returns that make the spending worth it.
Heat escaping through old glazing and gapped frames is the single largest avoidable loss in most older properties.
Few upgrades survive a home inspection as visibly as new windows and doors, and few carry as much of their cost through to the price.
Older frames soften, older locks wear, and both fail quietly. New units restore the resistance the opening was meant to have.
Tighter seals cut both noise and draft, which makes rooms usable that had quietly stopped being comfortable.
Most door faults are alignment rather than damage, and replacing the door fixes nothing if the frame moved. Property owners in London use Windows & Doors London for door repair, covering diagnosis, hinges, latches, frames, and weather seals.
Swapping a door without addressing the threshold and seals just moves the draught somewhere else. Property owners in London use Windows & Doors London for door replacement, covering measurement, removal, fitting, thresholds, and weather seals.
Putting a door where none existed means framing, headers, and finishes, not just the door itself. Property owners in London use Windows & Doors London for new door installation, covering framing, headers, fitting, trim, and making good.
Most windows written off as needing replacement need hardware and seals instead. Homeowners in London use Windows & Doors London for window repair, covering hinges, handles, gaskets, glazing units, and honest replacement advice.
Replacement is worth it when the frame has gone; before that it is usually money spent early. Homeowners in London use Windows & Doors London for window replacement, covering survey, removal, fitting, insulation, sealing, and finishing.
Cutting a new opening is structural work before it is glazing work, and the lintel comes first. Property owners in London use Windows & Doors London for new window installation, covering lintels, opening formation, fitting, and making good.

The part you never see and the part that matters most. It is why the frame is still square in fifteen years rather than bowed at the middle.

Quality products, dependable service, and results that last — here is what sets our team apart.
We had four windows replaced at our house near Lambeth. Windows & Doors London measured accurately, fitted square, and the trim looks like it was always there.
Our back door around Old South had dropped so far it scraped the tile. They rehung it on new hinges and adjusted the frame. No more mark on the floor.
The sliding door at our condo over by Huron Heights had come off the track twice. They fitted a proper roller set and it has not moved since.
Our commercial entrance just off Stoneybrook needed a panic bar replacing to pass inspection. Done overnight and the certificate paperwork was sorted for us.
A key snapped in the lock at our place out toward Byron. The technician extracted it, serviced the cylinder, and cut two spares on the spot.
The picture window at our home near Masonville was fogging badly. New sealed unit fitted and the difference in the room temperature was noticeable immediately.
Our storm door around Old North would blow open in any real wind. They fitted a heavier closer with a wind chain and that was the end of it.
The deadbolt on our front door over by Wortley Village never lined up with the strike. Turns out the frame had moved. They corrected it rather than filing the plate.
Our shopfront glass just off Oakridge needed replacing after a break-in. Same-day board-up, then toughened glass in within forty eight hours.
The casement windows at our place out toward White Oaks had stiff handles throughout. All serviced in one visit for less than I expected one to cost.

Most standard vinyl windows in London 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 London 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 London 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 London 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 London 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 London 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 London 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.
