I’m not one to throw money at just any home improvement project, but when it comes to windows, I’ve found a gem in Mathews Brothers. These windows aren’t just functional; they’re a game-changer for energy efficiency, durability, and style.
After installing them in my own home, I can confidently say they’re worth every penny. Whether you’re upgrading for aesthetics, slashing energy bills, or just tired of drafty old windows, Mathews Brothers delivers.
Let me walk you through my experience, the pros, the not-so-great parts, maintenance tips, and how they stack up against the competition—you’ll see why I’m hooked.
My Experience With Mathews Brothers Windows

When I decided to replace the creaky, drafty windows in my New England home, I wanted something that could stand up to brutal winters and salty coastal air.
Mathews Brothers, a Maine-based company with a legacy stretching back to 1854, caught my attention.
I went with their Sanford Hills triple-pane vinyl windows, hoping they’d deliver on energy efficiency and durability without breaking the bank. Spoiler alert: they did.
The process started with a visit from a local dealer, who was refreshingly straightforward—no pushy sales tactics, just facts about window ratings and customization options. I chose a mix of double-hung and casement windows to match my home’s traditional vibe.
Installation was a breeze, thanks to the pre-applied J-channel on the Sanford Hills line, which made the windows rigid and easy to fit. The crew had them in within a day, and I was impressed by how square and true they sat—no wavy frames or air leaks here.
Living with these windows for over a year now, I’ve noticed a real difference. My heating bills dropped noticeably last winter, and the house feels quieter, even with a busy road nearby. The triple-pane glass is a beast at blocking noise and keeping the cold out.
I also love the tilt-in feature for cleaning—popping the sash in and wiping it down takes minutes. One small hiccup: the visible light transmittance (VLT) is a bit lower than I’d hoped, so rooms feel slightly dimmer on cloudy days. But honestly, the energy savings and sturdy build make it a minor trade-off.
Mathews Brothers has earned my trust, and I’m excited to share why.
Pros of Mathews Brothers Windows
- Energy Efficiency That Saves You Money

Let’s talk about keeping your wallet happy.
Mathews Brothers windows, especially their Sanford Hills triple-pane models, are designed with energy efficiency in mind.
With U-factors as low as 0.19, these windows are like a thermal blanket for your home.
In my case, I saw a 15% drop in my heating costs last winter, which adds up fast. The Duralite warm-edge spacers and optional low-E coatings trap heat in during winter and keep it out in summer.
If you’re in a cold climate like me, you’ll appreciate how these windows make your home feel cozy without cranking the thermostat.
- Durability Built for the Long Haul
These windows are tough as nails. Made in Belfast, Maine, Mathews Brothers uses high-quality vinyl that resists warping, cracking, or fading, even in harsh coastal conditions.
My home gets battered by salty air and freezing winds, but after a year, the frames still look brand new—no peeling or discoloration. The Sanford Hills line, with its beefy 1¾-inch sash members, feels solid, not flimsy like some cheaper vinyl windows I’ve seen.
Plus, their Limited Lifetime Warranty (including five years of labor) gives me peace of mind that they’ll stand behind their product if anything goes wrong.
- Easy Installation and Customization
I’m no contractor, but I could tell the installation process was smooth. The pre-applied J-channel and compression seal weatherstripping made it easy for the crew to get a tight, leak-free fit.
Mathews Brothers offers both replacement and new construction lines, so whether you’re retrofitting an old home or building new, they’ve got you covered.
You can also customize with exterior paint colors or a wood-like laminate interior for that classic look without the upkeep. I went with a crisp white exterior to match my home’s colonial style, and it’s spot-on.
- Low Maintenance, High Convenience
One of my favorite things?
These windows are practically maintenance-free. The vinyl frames don’t need painting or staining, unlike wood windows that demand constant care. Cleaning is a snap—tilt the sash in, wipe it down, and you’re done.
The integral finger lift on the sash makes opening and closing smooth, even for someone like me who’s not exactly a bodybuilder. The hardware feels sturdy, and the locking mechanisms are some of the best I’ve used—no janky latches here.
- Made in America with a Legacy of Quality
There’s something satisfying about supporting a company that’s been crafting windows since 1854. Mathews Brothers is America’s oldest window manufacturer, and their Maine roots shine through in their attention to detail.
Knowing my windows were made locally by folks who understand New England’s weather felt like a win. Their reputation for quality is backed by builders I’ve talked to, who rave about the consistent performance and reliable customer service.
Not-So-Good Parts of Mathews Brothers Windows
- Lower Visible Light Transmittance

Okay, let’s be real—nothing’s perfect.
One thing I noticed is that the triple-pane windows have a lower visible light transmittance (VLT) of around 0.4.
This means less natural light filters into the room compared to some double-pane options.
On gloomy days, my living room feels a tad dimmer than it did with my old windows. It’s not a dealbreaker, especially since the energy savings are worth it, but if you’re obsessed with bright, airy spaces, you might want to discuss glass options with your dealer to find a balance.
- Limited Distribution Network
Mathews Brothers doesn’t sell directly to consumers, which can be a hassle. You have to go through their network of dealers in New England and parts of New York.
For me, finding a local dealer was easy, but if you’re outside their distribution area, you’re out of luck. I wish they’d expand their reach or offer a direct-to-consumer option for folks who want to skip the middleman. It’s not a huge issue, but it’s something to consider if you’re not in their region.
- Higher Upfront Cost
These windows aren’t the cheapest on the market. The Sanford Hills triple-pane models I chose were pricier than some budget vinyl options, like those from Window World. For a full home replacement (10 windows), I spent around $12,000, including installation.
While the energy savings and durability justify the cost over time, it’s a big upfront investment. If your budget is tight, you might need to prioritize which windows to upgrade first or explore their more affordable Spencer Walcott line.
- Potential for Condensation in Humid Climates
In my humid New England summers, I noticed some condensation on the interior glass during early mornings. This isn’t a flaw in the windows themselves—my home’s tight construction and high humidity are the culprits.
However, if you live in a humid area and don’t have great ventilation, you might see this too. It’s manageable with a dehumidifier, but it’s worth noting if you’re in a similar climate.
Maintenance Tips For Mathews Brothers Windows
- Keep the Tracks Clean

To keep your windows gliding smoothly, give the tracks a quick clean every few months.
I use a vacuum with a brush attachment to suck up dust and debris, then wipe the tracks with a damp cloth and mild soap.
Avoid harsh chemicals—they can damage the vinyl.
For my double-hung windows, I check the tilt latches and sash tracks to ensure nothing’s gunked up.
A clean track means less wear on the hardware and a smoother operation.
- Inspect Weatherstripping Annually
The compression seal weatherstripping on Mathews Brothers windows is top-notch, but it’s not invincible. Once a year, I inspect the weatherstripping around the frame for any signs of wear or gaps.
If you notice air leaks or fraying, contact your dealer for a replacement—it’s usually covered under warranty. A quick wipe with a silicone-based lubricant keeps the weatherstripping supple and prevents it from drying out.
- Clean the Glass Properly
Cleaning the glass is straightforward but requires a little care. I use a mix of water and a splash of vinegar (about 1:10 ratio) with a microfiber cloth to avoid streaks. Never use abrasive pads or ammonia-based cleaners—they can scratch the low-E coating.
For my tilt-in windows, I clean both sides every season, which takes about 10 minutes per window. If you’re dealing with stubborn spots, a drop of dish soap does the trick.
- Check for Condensation and Ventilate
If you notice condensation, like I did, it’s a sign your home might be too humid. I run a dehumidifier in the summer to keep humidity below 50%, which solves the problem. Make sure your home has good ventilation—crack a window or use exhaust fans when cooking or showering.
This not only prevents condensation but also extends the life of your windows by reducing moisture stress on the seals.
- Lubricate Hardware Sparingly
The locking mechanisms and hinges on Mathews Brothers windows are built to last, but a little TLC goes a long way. I apply a small amount of silicone spray lubricant to the hinges and latches once a year. Don’t overdo it—too much lubricant can attract dirt.
A quick spray, wipe off the excess, and you’re good to go. This keeps everything moving smoothly without sticking.
Comparing Mathews Brothers To Other Brands
I’ve looked into other window brands to see how Mathews Brothers holds up, focusing on LockTight Windows, Vector Windows, and Thermo-Tech Windows.
Each has its strengths, but here’s how they compare head-to-head with Mathews Brothers, based on my experience and research from chatting with homeowners and contractors.
- Mathews Brothers Vs. LockTight Windows

LockTight Windows, known for their aluminum-clad wood and vinyl options, are a solid choice if you’re after a sleek, modern look.
Their StormBreaker Plus line is built for hurricane-prone areas, with impact-resistant glass that’s tougher than Mathews Brothers’ standard offerings.
However, LockTight’s vinyl windows, like their EcoShield series, have a U-factor around 0.25, which isn’t as efficient as Mathews Brothers’ Sanford Hills triple-pane models at 0.19. I noticed LockTight’s frames feel less robust—some users report slight warping after a few years in harsh climates.
Mathews Brothers’ vinyl is thicker, and their Limited Lifetime Warranty (including five years of labor) beats LockTight’s 10-year limited warranty. For coastal New England homes like mine, Mathews Brothers’ durability and energy efficiency win out, though LockTight’s impact resistance is a plus in storm-heavy regions.
- Mathews Brothers Vs. Vector Windows

Vector Windows, based in Ohio, focuses on affordable vinyl windows with a strong emphasis on customization.
Their Z-250 series offers a wide range of colors and grid patterns, which is great if you’re picky about aesthetics.
I found their double-pane windows decent, with U-factors around 0.27, but they don’t match the energy savings of Mathews Brothers’ triple-pane options.
Vector’s installation process is straightforward, but their frames aren’t as rigid as Mathews Brothers’ Sanford Hills, which uses a pre-applied J-channel for a tighter fit.
Vector’s warranty is solid—lifetime on vinyl and glass—but doesn’t include labor, unlike Mathews Brothers’ five-year labor coverage. If you’re on a budget and want style, Vector’s a contender, but Mathews Brothers offers better long-term performance and lower maintenance for my needs.
- Mathews Brothers Vs. Thermo-Tech Windows

Thermo-Tech Windows, another vinyl-focused brand, prides itself on energy efficiency with their Classic Comfort line, boasting U-factors as low as 0.22.
That’s close to Mathews Brothers’ 0.19, but Thermo-Tech’s double-pane standard models don’t insulate as well as Mathews Brothers’ triple-pane Sanford Hills.
I also found Thermo-Tech’s hardware less user-friendly—their latches feel clunky compared to Mathews Brothers’ smooth, integral finger lifts.
Thermo-Tech’s windows are cheaper, with a full home replacement costing around $8,000-$10,000 versus Mathews Brothers’ $12,000, but their 15-year warranty feels skimpy next to Mathews Brothers’ lifetime coverage.
For cold climates, Mathews Brothers’ superior insulation and sturdier build make it the better pick, though Thermo-Tech is a good budget-friendly alternative.
Mathews Brothers stands out for its balance of energy efficiency, durability, and low maintenance, tailored to New England’s tough conditions. LockTight shines in storm resistance, Vector in customization, and Thermo-Tech in affordability, but Mathews Brothers’ robust vinyl, stellar warranty, and local expertise make it my top choice for long-term value.
