12 Best Window Companies Burlington, Ontario

Whether you're in a home close to the lake or further inland in Burlington, replacing your drafty windows is one of the highest ROI investments you can make for comfort and long-term value. Given Burlington's weather, meaning cold winters, humid summers, and the freeze-thaw cycles that come with an Ontario climate, the windows you choose need to be built for this specific region.

This guide rounds up 12 window companies Burlington homeowners can rely on. We'll walk through what each one does well, what past customers have flagged, and what to think about before picking up the phone.

What Burlington Homeowners Should Think About First

Before you start comparing quotes and having your windows replaced, here are a few things to keep in mind.

1. Manufacturer vs. Installer

Some companies design, build, and install their own products. Others source windows from external manufacturers and handle the installation side. Buying directly from the manufacturer usually means lower prices, faster service on defective units, and cleaner warranty accountability. When something goes wrong, there's no finger-pointing between a manufacturer and an installer.

2. Energy Efficiency for Burlington's Climate

Window replacements must comply with energy efficiency ratings and local climate needs. The right glass package can make a measurable difference in how warm your house stays in winter and how cool it stays in summer.

Look for double or triple glazing, Low-E coatings, argon or krypton gas fills between panes, and ENERGY STAR certification. Nowadays, most local companies in Burlington offer this, but the key is to work with a company that can customize them depending on your home’s specific needs.

3. Window Style and What Fits Your Home

If you’re planning to replace all the windows, work with a company that offers multiple window styles, as well as custom sizes. This way, you can choose based on your preferences and needs without being constrained by a limited number of window types. Plus, you can also save some money when you’re replacing all the windows at the same time.

4. Doors, While You're at It

Most of the companies on this list also offer other high-quality products like entry doors and patio doors. If your front door is letting in cold air or your patio door sticks in winter, you can bundle door and window work in a single project, which often saves money on labour and finishes everything at once. Your home's curb appeal will get a significant boost if you update doors and windows together.

5. Installation Quality Matters as Much as the Product

It’s usually best to work with a company that offers window installation services as well and has its own installation teams. If the window is installed carelessly, without proper sealing, flashing, or insulation around the frame, it can leak air, collect moisture, and fail years before it should. Also, ask if the company offers both installation methods: full-frame replacement and retrofit installation.

6. Free Quotes and Transparent Pricing

Most window companies in Burlington offer a free in-home consultation with estimates that break down the final window replacement cost. It’s best to get more than one. If a company gives you a quote that doesn't break down material, labour, disposal, and any trim or carpentry work separately, it’s worth asking for more details before committing. Vague pricing and time-limited discount pressure are both signals worth paying attention to.

7. Warranty

A big number on a warranty card doesn't mean much if the coverage is riddled with conditions. What specifically is covered: frame, glass unit, hardware, labour? Is it transferable to a new owner if you sell? How is a claim actually handled? In other words, make sure the company you choose offers a comprehensive warranty with clear terms.

12 Window Companies Serving Burlington

We’ve selected 12 companies for window replacement in Burlington (arranged in no particular order) based on their product offering, their longevity in the window market, and client satisfaction. Here’s a quick overview of the most important details, which we’ll discuss more about below:

1. Magic Windows and Doors

Magic has spent over 40 years building and installing windows for homeowners across Southern Ontario, with Burlington firmly within its service area. What makes Magic different from other companies on this list is that we took window technology to another level.

All our products are manufactured with the Magic proprietary Hybrid Fusion Frame, which combines vinyl with aluminum and steel reinforcement, giving the frame considerably more structural rigidity than a hollow vinyl alternative without adding bulk to the sightlines. Moreover, the Magic Parallex hardware replaces the traditional crank mechanism on casement windows with a simpler push-and-swing motion.

And alongside windows, Magic also offers exterior doors, including front door replacements and patio door replacements (e.g., sliding doors and French doors).

Noteworthy highlights:

• Designs, manufactures, and installs its own products with no third-party manufacturer involved
• Hybrid Fusion Frame combining vinyl, aluminum, and steel for a structurally reinforced yet slim frame for more natural light
• Parallex push-to-open hardware replacing hand-crank mechanisms on casement windows for easy cleaning
• Deeper glass cavities allowing more argon gas fill for stronger insulation
• 40-year warranty backing all window units
• Multi-point locking systems for enhanced home security
• Retractable Slide'N'Hide screens that fully disappear when not needed
• Optional integrated solar shades and thermal blinds to reduce heat gain
• Hi-Flo drainage channels to clear water and discourage insects

Important considerations:

• Magic's in-house technology and long warranty terms put them at a higher price point than budget window lines.

2. Dayside Windows and Doors

Dayside has a history in Burlington that goes all the way back to 1959. Their current manufacturing facility in Brantford handles the full production of every window and door they sell, including custom shapes, condo units, and replacement windows for standard residential homes across southwestern Ontario.

Burlington customers who've reviewed Dayside online consistently single out the expert installation teams for professionalism and thoroughness. Their sales approach centres on helping homeowners choose the right product across multiple variables, like style, energy performance, and cost, rather than steering everyone toward the same solution.

Noteworthy highlights:

• Founded in Burlington in 1959, one of the oldest names on this list
• Full range of high-quality windows and doors
• Tilt-and-turn windows available
• Durable Roto hardware
• Seamless quick-release screen
• ENERGY STAR certified windows

Important considerations:

• Some customers reported delayed delivery timelines that pushed back their project start dates beyond what was initially discussed.

3. West Windows & Doors

West Windows & Doors has been operating out of Burlington as a family-owned company with over four decades of experience. They’re installing vinyl windows made by Strassburger, as well as Marvin wood and fiberglass windows, giving Burlington homeowners access to solid product lines at a competitive price point.

Their team has built a strong reputation for walking homeowners through the energy rebate programs available in Ontario to help offset the window replacement cost.

Plus, the company has a showroom at 2462 Industrial St, Burlington, where you can speak to one of their sales representatives directly.

Noteworthy highlights:

• All installations performed by West's own teams
• Owner-supervised jobs across Burlington and surrounding communities
• Works with Strassburger and Marvin windows
• Multiple frame material choices: vinyl, wood, fiberglass
• Multiple window styles available, including corner windows, tilt-and-turn windows, specialty windows

Important considerations:

4. Everest Windows & Doors Inc.

Everest Windows & Doors has been operating as a full-service manufacturer and installer for more than a decade. They've racked up six consecutive HomeStars Best of Awards and over 300 five-star Google reviews, which speaks to consistent execution across a large number of projects.

Their product lineup includes the full range of residential styles, casement, awning, sliding, picture, bay, and bow windows, as well as entry doors, patio doors, and storm doors. They also often have various packages that benefit many homeowners. For example, they currently offer one free patio door for 10 installed windows, a free patio door with mini blinds for 14+ installed windows, and free basement windows if you replace all the windows in your house. (Check their website regularly, as these promotions change frequently).

Noteworthy highlights:

• ENERGY STAR certified, Ontario-manufactured windows and doors
• Six consecutive HomeStars Best of Awards
• Full range of window and door styles, including bay windows, bow windows, and custom shapes

• Flexible financing options

• 7/8” insulated thermal dual-seal glass with Quanex Super spacer
• Shadow groove cleaned corners

Important considerations:

• Some customers reported post-installation communication delays.

5. Euro Star Windows & Doors

Euro Star has been in business since 1992. The company specializes in European-style tilt-and-turn window systems, a style that's far less common in Canadian window companies but offers real practical advantages, including the possibility to tilt the top of the sash inward for ventilation while it stays locked at the bottom for security.

Their triple-pane systems with Low-E coatings and argon fills achieve U-factors as low as 0.22, which can translate into significant reductions in energy bills. Every unit is tested for multi-point locking and weatherseal performance before leaving for installation.

Noteworthy highlights:

• Specializes in European tilt-and-turn, casement, bifold, and lift-slide window systems
• Possibility to use invisible hinges
• Vinyl and aluminum windows available
• ENERGY STAR certified
• Multi-point locking hardware
• Stainless steel hinges

Important considerations:

• European tilt-and-turn systems are less familiar to most Ontario homeowners and can feel different from the casement or slider windows they're replacing. It’s best to visit a showroom to confirm how they operate.

6. Linton Window & Door

Linton has been a fixture in southwestern Ontario since 1974. Burlington falls within their service area, and they've completed a substantial number of Burlington-area projects to strong customer satisfaction.

Rather than manufacturing in-house, Linton carefully selects manufacturers and product lines, primarily North Star windows, along with Vinylbilt and Southfield. 

Noteworthy highlights:

• Family-owned and operated since 1974

• ENERGY STAR windows
• Super Spacer technology
• Fusion-welded corners

Important considerations:

• Linton is a dealer, not a direct manufacturer. This means that product availability depends on the supplier. Make sure to confirm product availability and schedule the installation process early on.

7. EcoTech Windows & Doors

EcoTech has been running installations across Ontario, including Burlington and the surrounding regions, for over two decades. Their UPVC window frames use a 26-chamber construction, and their EcoSmart product line is built to meet the NAFS-22 performance standard, which is one of the more demanding benchmarks for Canadian window products.

One practical feature that stands out: EcoTech's corner-driver locking mechanism produces an audible click when the window is properly sealed, which takes the guesswork out of whether it's actually locked and weatherproof.

Noteworthy highlights:

• 26-chamber UPVC frame construction with thick-wall profiles
• EcoSmart line meeting the high standards of NAFS-22 performance
• Audible corner-driver locking confirmation on each window
• Over two decades of experience serving Ontario, Burlington included, homeowners
• Multiple Top Choice Awards and HomeStars recognitions

8. Centennial Windows & Doors

Centennial was founded in London, Ontario, 45 years ago and has completed over 500,000 window and door installations over the years. The company makes its own windows and doors, uses factory-trained installation employees exclusively, and backs its work with a no-fine-print lifetime warranty.

They also have sales sometimes. At the moment, for example, you can save $500 per window & door for the company’s 45th anniversary.

Noteworthy highlights:

9. Canadian Choice Windows & Doors

Canadian Choice has been one of Ontario's larger window manufacturers for decades, producing everything in-house and assigning a dedicated project manager to each job.

Their DraftLOCK™ series stands out for performance. Moreover, their TrueCrankless casement windows open up to 180 degrees, making upper-floor cleaning considerably more manageable.

Noteworthy highlights:

• In-house manufacturing facility with province-wide installation coverage
• DraftLOCK™ series for improving your home's energy efficiency
• TrueCrankless windows opening up to 180 degrees for easier maintenance
• 25-year transferable warranty on all product lines
• 40+ customization options

Important considerations:

• Since Canadian Choice is a multi-region manufacturer operating across Ontario, some Burlington customers reported longer waits on post-installation service calls.

10. Nordik Windows and Doors

Nordik now ranks among the fastest-growing window and door companies in Canada. The company backs every installation with its "No-Bull" 25-year warranty.

Their RevoCell® material, a microcellular PVC, is stronger and better insulated than hollow vinyl frames at a comparable price. Some of their products carry ENERGY STAR Most Efficient certification in standard double-pane configuration. 

Noteworthy highlights:

• RevoCell® microcellular PVC frame, stronger and better insulated than hollow vinyl
• ENERGY STAR Most Efficient certification in double-pane configuration
• 25-year "No-Bull" warranty covering product, window installation, and service

11. Clera Windows + Doors

Clera has been manufacturing windows and doors since 1978. Their factory-direct structure eliminates the dealer layer entirely, so Burlington homeowners pay the manufacturer's price. Clera's window lineup includes casement, awning, tilt, and slider styles in a wide range of frame colours and glass configurations.

One technical detail worth noting: Clera uses wet-glazed frame and sash construction, which means the glass is sealed into the frame using a continuous bead of sealant rather than dry-set glazing tape. That method produces better resistance to water and wind infiltration.

Noteworthy highlights:

• Manufacturing since 1978
• Factory-direct pricing with no dealer intermediary
• Wet-glazed construction for improved water and wind resistance
• Customizable casement, awning, tilt, and slider styles across a wide colour range
• Vinyl and wood windows available
• Super Spacer technology.

Important considerations:

• Some customers reported communication issues and delays.

12. Pollard Windows and Doors

Pollard has been manufacturing top-quality windows and doors in Burlington since 1948, being one of the oldest window manufacturers in Ontario. That local production base means shorter supply chains, faster service on warranty claims, and a direct relationship between the manufacturer and the installer, since Pollard handles both.

The Pollard window lines include: Advantage Line (low-maintenance vinyl replacement windows), Advantage Plus (premium windows awarded the ENERGY STAR Most Efficient mark in 2025), and Liberty Collection (wood-clad vinyl windows).

Noteworthy highlights:

• Manufacturing windows and doors in Burlington since 1948

How long does it take to replace a window in Burlington?

Window installation is usually completed in one day in Burlington, but the timeline depends on installation complexity.

How do I choose the right replacement windows for my home?

Start by considering your home's age, your budget, and your energy-efficiency goals. Look for windows with Low-E glass, argon gas fills, quality hardware, and strong warranties. It's also important to choose a reputable company that provides professional installation, as even high-quality windows can perform poorly if they're installed incorrectly.

Do Burlington window companies offer financing?

Yes, many window companies serving Burlington offer financing options that let homeowners spread the cost over monthly payments. Financing programs vary by company, so compare interest rates, promotional offers, repayment terms, and any applicable fees before deciding.

Can replacement windows increase my home's value?

How can I tell if my windows need replacing?

Common signs include drafts, condensation between glass panes, difficulty opening or closing windows, rising energy bills, rotting frames, water leaks, and outside noise becoming more noticeable. If your windows are over 20 years old and showing several of these signs, replacement is often the better long-term solution.
