Top 5 Window & Door Repair Companies in Toronto & the GTA
Every year, the team at Revitalize Windows & Doors connects with hundreds of homeowners, contractors, and property managers across Toronto and the GTA — all with one thing in common: they need reliable window and door repair. Because so many of them turn to this site for our honest take on the industry, we get asked the same question pretty often: “Who else do you recommend for window and door repairs in the area?”
We’ve never been the type to dodge that question. So here’s a straightforward list of other companies with a solid track record for window and door repairs in Toronto and the GTA.
Before we get into the list, it’s worth framing why that information matters. After years of working in this industry and talking to hundreds of clients across the GTA, we’ve learned that most people don’t know what to look for when vetting a window or door repair company. They know something’s broken and they need it fixed. What they don’t always know is that the right company depends entirely on what’s broken, where they live, and whether the job calls for a specialist or a generalist.
The window and door repair industry in Toronto is also far less regulated than most homeowners assume. There’s no licensing body that governs who can hang out a shingle and take your call. That means the burden of doing basic due diligence — confirming insurance, checking service scope, understanding what a warranty actually covers — falls entirely on the consumer. That’s the context we’re bringing to this list — not to steer you toward or away from anyone, but to make sure you know what each company actually does and what questions to ask before you book.
1. Windowfix
Founded: 2007 Service Area: Mississauga, Oakville, Burlington, Milton, and the wider GTA
Windowfix was founded by Keith Childerhose and Sarah Taylor in 2007 and has been operating out of Mississauga for close to two decades. Their listed services include window hardware repair — cranks, hinges, and locks — along with foggy glass replacement and cracked glass replacement in both residential and commercial settings.
Their website states that they offer a 10-year warranty against seal failure on glass replacements installed in vinyl-framed windows. They describe their approach as providing efficient, quality, and friendly service, and they position themselves specifically as a repair company rather than a window replacement business.
From an industry standpoint, what matters here is the distinction between a repair-focused company and a replacement-focused one. In our experience working across the GTA, one of the most common frustrations homeowners run into is being told they need a full window replacement when only the hardware or glass unit has failed. A company that lists repair as its primary service — and backs that with a decade-long warranty — is offering something structurally different from a company whose revenue model depends on selling new units. Understanding that difference before you pick up the phone is half the battle.
2. Window Restoration Experts
Founded: Family-owned, serving the GTA from North York Service Area: Markham, Vaughan, Richmond Hill, Whitby, Newmarket, and surrounding GTA
Window Restoration Experts describes itself on its website as a fully insured, WSIB-certified, family-owned business based in North York. Their listed services include wood window restoration, window hardware repair, caulking, resealing, screen replacement, and full window replacement when required. They also advertise serving residential, commercial, and industrial high-rise properties.
Their stated philosophy, as described on their site, is that many homeowners are told to replace windows that could be repaired or restored at a fraction of the cost. They position diagnostics and restoration as the first step in their process, with replacement as a last resort rather than a default.
WSIB certification is worth understanding in this context. Any company sending a technician to work at height — on a ladder, on a scaffold, near glass — should carry WSIB coverage. It protects the worker, and it protects the homeowner from liability if something goes wrong on the job. It’s one of the first things we tell anyone to verify before signing a contract with any contractor, in this industry or otherwise.
The specific mention of high-rise and industrial properties in their service description also indicates a company set up with the logistics, insurance, and equipment to handle jobs beyond a standard single-family home — a meaningful distinction if you’re a property manager coordinating repairs across multiple units.
3. Jay’s Glass
Founded: Established, operating 24/7 Service Area: Full GTA, based near Yonge & Eglinton, Toronto
Jay’s Glass is based in the Yonge and Eglinton area of Toronto and advertises 24/7 emergency service across the GTA. Their listed services include cracked thermal glass unit replacement, foggy window pane replacement, broken glass replacement, and broken window part repair, in both residential and commercial settings including storefronts.
Their website offers free quotes and lists the option to send a photo of the damage by text for an immediate estimate — a process that speaks to a company structured around fast turnaround. They describe their service as fast and affordable, with a clear emphasis on glass-specific repairs rather than full window replacement.
Here’s what matters practically: thermal glass unit replacement and full window replacement are two very different things, and the price difference is significant. A failed seal or cracked pane in an otherwise functional window frame is a glass problem, not a window problem. A company whose service list leads with glass replacement rather than window sales is answering a different question — and usually a cheaper one. Knowing that distinction before you call anyone saves you from paying for more than you need.
The 24/7 service offering also has a specific practical use case. Broken glass in an occupied home or business is not something most people can or should leave overnight. A company that has built its operations around emergency response — including after-hours and weekend calls — exists precisely for those situations.
4. WeFix Windows & Doors
Service Area: Greater Toronto Area
WeFix Windows & Doors offers window and door repair services across the Greater Toronto Area, covering the everyday issues homeowners and property managers deal with most — hardware that’s stopped working, drafts coming through the frame, and glass-related repairs that don’t require a full window replacement.
What stands out about WeFix is their straightforward focus on repair. In an industry where a lot of companies lead with replacement, a business positioned around fixing what’s already there fills a real need for homeowners who want a practical, cost-effective solution without the pressure of a sales conversation.
As with any contractor you’re considering for the first time, we’d always recommend a quick conversation before booking — confirming they’re insured, understanding what their warranty covers on parts and labour, and making sure their service scope lines up with your specific job. That’s good practice regardless of which company you call, and any reputable operation will welcome those questions without hesitation.
5. PM Glass
Founded: 1993 Service Area: Scarborough, Toronto, North York, Etobicoke, Markham, Vaughan, Ajax-Pickering, and the wider GTA
PM Glass has been operating out of Scarborough since 1993, making them the longest-running company on this list. They describe themselves as a family-owned and operated business focused on fast response times, consistent work quality, and customer satisfaction.
Their listed services include 24/7 emergency glass replacement, safety and tempered glass, thermal glass units, patio door repair, patio door screens, mirrored walls, frameless shower glass, vinyl glass window repair, foggy glass repair, and storefront repair. They also explicitly advertise insurance-approved emergency service — meaning they are set up to work directly within the insurance claim process, not just alongside it.
Over thirty years in operation represents something concrete in this industry: exposure to how building codes, glass standards, and insurance requirements have evolved, and the operational experience to work within all of them. That’s not an opinion — it’s a function of time in the field. A company founded in 1993 has seen product lines come and go, watched energy efficiency standards change, and navigated shifts in how insurance companies handle emergency glass claims. That institutional depth shows up in the specificity of their service list — piano hinges, foggy glass condensation repair, storefront security restoration — details that reflect experience with a wide range of real jobs rather than a generic service menu.
The insurance-approved designation is also practically significant. Filing a glass replacement claim through your home or business insurance involves documentation, timelines, and approvals that not every contractor knows how to navigate. A company that explicitly positions itself to handle insurance-approved emergency work has built that process into how it operates — which means less back-and-forth for the homeowner at an already stressful time.
A Few Questions We Get Asked Often
How do I know if I need a repair or a full replacement?
In most cases, the frame and the glass are two separate problems. If your frame is structurally sound, a hardware repair or glass unit replacement is almost always the right first step. Full window replacement becomes the conversation when the frame itself is damaged, rotted, or warped beyond what a repair can address. Any reputable company should be able to tell you which situation you’re in before quoting.
What should I ask before hiring a window repair company?
Four things: Are you insured? Are you WSIB-certified? How long have you been operating? And what does your warranty cover on parts and labour? A company that answers all four clearly and specifically is a company that stands behind its work.
Why does it matter whether a company specializes in repair versus replacement?
It matters because their incentives are different. A company whose primary revenue comes from selling new windows has a financial reason to recommend replacement. A company whose business model is built around repair has a financial reason to fix what’s already there. Neither is inherently dishonest — but knowing which type of company you’re talking to helps you understand the advice you’re getting.
Does the age of a company matter?
Longevity in this industry matters in a specific way: it means the company has navigated enough jobs, enough product changes, and enough customer situations to have developed real processes. A company that has been operating for fifteen or thirty years has handled problems that a newer company hasn’t encountered yet. That experience tends to show up in how efficiently a job gets done and how the company handles it when something doesn’t go to plan. It also tends to show up in how clearly a company can explain what they’re doing and why — which is usually the clearest signal of all.
