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 Bolton restores both for properties across Bolton 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.
No jargon and no vague warnings. We show you the worn part and what it is doing to the rest.
Our after-hours line reaches a technician, not a message service that calls back on Monday.
The estimate is a commitment. Extra work needs your approval before it happens.
A guarantee is only useful if someone answers when you use it. Ours is honoured without argument.
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 Bolton use Windows & Doors Bolton 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 Bolton use Windows & Doors Bolton 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 Bolton use Windows & Doors Bolton 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 Bolton use Windows & Doors Bolton 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 Bolton use Windows & Doors Bolton 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 Bolton use Windows & Doors Bolton for new window installation, covering lintels, opening formation, fitting, and making good.

A galvanised steel core handles the expansion and contraction that comes with wide temperature swings, so the frame does not distort over the years.

Quality products, dependable service, and results that last — here is what sets our team apart.
The front door at our place near Albion Hills would only lock if you leaned on it. Windows & Doors Bolton corrected the frame alignment and it locks with one finger now.
Our bedroom windows around Palgrave 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 Sandhill. Secured the same night, reinforced frame and new lock fitted the next day.
The sliding door at our place just off Macville was grinding along the track. Rollers replaced and the track cleared. Silent again.
I managed to lock my keys in the house out toward Caledon East 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 Tullamore with an insulated one. The draught in the hallway has completely disappeared.
Our unit around North Hill needed keypad entry for cleaners and contractors. Set up so we can issue and cancel codes without calling anyone.
The storm door over by South Hill had a closer that had given up entirely. New closer, adjusted properly, and it shuts gently now.
Our stairwell window just off Bolton Village 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 Downtown Bolton had worn out. Replaced with a properly rated cylinder and rekeyed to match the front. One key now.

Most standard vinyl windows in Bolton 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 Bolton 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 Bolton 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 Bolton 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 Bolton 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 Bolton 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 Bolton 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.
