We heard from many Calgary homeowners that Norden Seal is the way to go for reliable window upgrades, so we checked them out.

First off, we love how everything Norden Sea does is customized—they don’t just offer a handful of standard-issue windows and doors.

The team showed us their extensive options, and the fact that all their products are made here in Canada (and are actually Energy Star certified for our climate) did give us some peace of mind.

It’s also worth noting that their windows are lead-free vinyl, so they stay looking new and hold up against Canadian winters. 

It’s also super helpful that they carry three types of installations—retrofit if you just want a swap, full-frame if you need a fresh start, and stud-to-stud aluminum for trickier renos.

Another thing we love is their free estimate and lifetime warranty. This just proved to us that they are confident in their work—and who doesn’t want less maintenance down the line?

On the flip side, some customers mentioned follow-ups can be slow if your project’s not moving forward quickly—you might need to give them a second call if things stall.

Top-tier quality and thorough installation

“Couldn’t be more grateful to the NordenSeal windows and doors team in Calgary. They did am absolutely phenomenal job with the replacement and installation of 6 windows in my home. Install was all day in one day, and they even did an amazing job cleaning up after themselves, great customer service!

The quality of the windows are top tier, immediately feel the difference and the way the windows open you can tell its extremely high quality. Would highly recommend them to anyone looking to get their windowsand/or doors done in Calgary!”

I really appreciated how much pride they take in their work and how responsive they were to every question I had. I highly recommend Norden Seal to anyone looking for reliable, high -quality windows and doors.”

Window Mart’s showrooms stand out with their extensive and well-organized selection of uPVC vinyl window styles and finishes—all laid out side by side, which makes comparing your options so much easier.

Everything here is customizable, so if you’re looking for more than just the typical sizes or standard designs, they’ve got you covered.

When it comes to credibility, Window Mart checks nearly every box. Their team is ACA, ECA, and CSA certified, and they back their work with a $5 million liability insurance policy plus WCB coverage.

Their warranty packages impressed us too, with some going up to 25 years. People we spoke with highlighted how their flexible financing actually helped and that booking a free estimate was straightforward.

Of course, nothing’s perfect—a few folks mentioned that the crew didn’t always leave the place spotless or that an install here and there needed some touch-ups. But the upside is that Window Mart was quick to respond and resolve any problems. 

Detail-oriented service

“We are very pleased that we went with Window Mart for our new windows and doors. We had 11 windows, the front entry door, and the sliding patio door that needed to be replaced. We decided to go with Window Mart because Andrei was very helpful and explained everything about the manufacture and the efficiency of the windows in detail. He was very friendly and took the time to work with us on the best windows and doors for our needs. Our front door was not a standard size and Andrei Gave us a great solution. The technicians that came and did the installation were very efficient and professional. They were very precise on installing the new windows and doors, and made sure everything was clean before they left. The quality of the windows and doors exceeded our expectations. The reduction in outside noise is very noticeable.”

Professional team

“I ordered new windows from WindowMart and I’m absolutely thrilled with the result! The installation team — Maksym, Oleksiy, Taras, and Denys — arrived right on time and completed a fantastic job in just a few hours.👌

The guys were extremely professional, polite, and careful. The installation went smoothly without any issues, and they cleaned up all the debris afterwards, leaving everything neat and tidy.

I’m really glad I chose WindowMart. Highly recommended! 👏”

Ecoline’s Calgary warehouse has the whole lineup—classic vinyl windows, some surprisingly sleek steel and fibreglass doors, and all the styles you’d expect, like casement, slider, and bay, to name a few.

Everything’s triple-pane if you want max energy savings, and every single option is Energy Star and NAFS-22 certified.

We love that Ecoline doesn’t hand you off to random subcontractors—they actually do everything, start to finish, with their own crew. Plus, they’re big on following CSA standards and WCB coverage, which felt reassuring.

Their warranty game is top tier too: 25 years on product and labour, plus that direct price guarantee (no middleman, no upcharges).

The folks we talked to kept bringing up how clear Ecoline is on timeline, install expectations, and even how to get those juicy government rebates on upgrades.

However, the showroom is popular, so if you’re in at a busy time, the staff might get pulled in a few directions. We weren’t left ignored, but you’ll notice the wait when it gets crowded.

High-quality windows

“Matt and his staff did our beautiful windows and install our storm door we purchased from a different store.  They patiently did those for couple of days while too cold outside.  They were beautifully and perfectly done.  Our house look so much newer with those new windows installed.”

– Fannie Cortiguerra, Google Review

Polite service with attention to detail

“Awesome  service !!Matt and is crew  did a awesome job clean,polites and answer all  my question!!  Matt  showed me all the lock systemes on  all windows and doors

Even with the  some rain ,they waited for it to pass and completed the job!! They also replace f piece of siding around doors     that was worned off!!”

GreenFox Windows & Doors does pretty much everything in-house, from manufacturing each window to getting its own crew to install it. This means you won’t be bouncing between different companies!

With them, you’ll be spoiled for choice. Whether you need a classic bay window, something funky and custom-shaped, or just want to pick a colour that’s not “safe” beige, they make it happen.

They’re also obsessed with streamlining everything—getting a quote, launching into a free in-home consultation, and then booking an install—it all feels super painless.

They make a big deal out of their lifetime, fully transferable warranty that even covers workmanship, and honestly, that’s a huge peace-of-mind boost. People we spoke to highlighted this and added that GreenFox doesn’t do any hard-sell thing.

The caveat? If you need aftercare, brace yourself. More than a couple of customers told us it took ages to get responses, if at all, once the job was finished.

Smooth installation

“We were very happy with Greenfox from start to finish.  When we got our quote, everything was explained to us.  The install went seamlessly & they were very friendly, and clean.  The windows look great & is a huge improvement.  We are looking forward to seeing the difference,  in the winter, with warmth.  We highly recommend Greenfox!”

Meticulous installers

“Mike Dansiuk and his colleague were by far the best installers! They were fun and polite and explained everything with ease for us as the customer. They were clean and meticulous and we would love to have them come back to finish the rest of our installs! Our animals loved them too!”

We’ll admit, we kind of geek out over companies that double down on local know-how, which is why Window Seal West made such a good impression on us. Here, they offer Canadian-made, energy-efficient stuff that’s clearly built with Alberta winters in mind.

We love that their lineup covers all the basics (vinyl windows, entry doors, and patio sliders) but without that cookie-cutter vibe. Everything is pretty customizable, too!

Everyone in the team was super approachable and quick to break down the details, from materials to warranty. What stands out? It’s their 25-year warranty and the free, no-pressure estimate!

They’re also one of the few places that’ll talk you through financing with zero awkwardness. Most of the folks we heard from said their installations are fast (some even got urgent repairs the same day). 

As a heads-up: we’d suggest giving your new windows a really good look once they’re in, since a handful of folks noticed installation measurements were off around the frames.

Professional sales

“We had a fantastic experience with Windows Seal West from start to finish. The entire team was professional, but we want to give a special shout-out to Oleysa and Antony’s Installation Team for their outstanding service. They made the sales process was professional and easy. The installation was seamless the crew was outstanding. The quality of work is top-notch, and the team’s attention to detail really stood out. We are thrilled with the results and highly recommend them to anyone looking for window services!”
