Unisson Groupe caught our eye with their claim of crafting each window individually – now that’s attention to detail. It’s believable too. Their 100% UPVC windows are not only visually stunning but also technically sound. 

They use advanced technology and materials in the manufacturing and installation process. For instance, their triple-glazed windows feature a unique “Super Spacer” insulating glass spacer that boosts energy efficiency and durability. 

When we visited, they showed us a ton of different styles, from traditional casement windows to elegant bay windows. Plus, they can even create custom shapes.

Of course, we had to chat with some of their customers while we were there. What stood out was how happy they were with Unisson’s free estimates. They felt like the whole process was transparent and straightforward. 

We also love that they use 100% lead-free materials and recycle whenever possible. It’s good to see a company that cares about the environment.

Delivers attentive and responsive customer service

“We were referred to Unisson Groupe by several satisfied friends and initially engaged their services in 2021 for window and entry door replacements. This year, we chose them again to complete the rest of our window replacements. Our recommendation for Unisson Groupe is based on several factors: their attentive sales staff who readily address inquiries, the evident quality of their window products showcased at their office, the skilled installation team, and their responsive approach to addressing any post-installation issues. Overall, we confidently recommend Unisson Groupe for their professional service and quality products.”

Factory Direct definitely caught our attention with their wide array of window styles and materials. They aren’t a one-size-fits-all kind of company, and we love that they cater to different needs and preferences. 

We were honestly blown away by the variety of window options they offer. From uPVC to hybrid and aluminium windows, there’s something for everyone. 

Their windows are not only energy-efficient but also low-maintenance. They feature innovations like triple glass and low-E Glass to improve insulation and reduce energy costs. 

We were also impressed with their competitive pricing. They manage to keep costs down without skimping on quality. Plus, they offer free estimates within a 100-mile radius, which makes it easy and convenient to get started.

We also have to give them credit for their participation in the Greener Homes initiative. This program helps customers qualify for rebates on energy-efficient windows, which is a fantastic bonus. 

They also don’t just stop at windows. They offer a comprehensive range of services, including window and door installation, patio door installation, and garage door replacement. 

Honours installation dates as promised

“It was my first time buying from Factory Direct and I am very satisfied with my experience with them. We had 4 windows and 3 steel doors and a patio door installed. Starting with Tony Semeraro, the sales rep who guided us with our project. He was very knowledgeable and kept his word on the date of the installation. Max and his crew came to do the installation. They were amazing, starting with making sure to cover the floors and the furniture. You could tell they love their job. They made sure of every little detail and after the work was done they vacuumed and cleaned up completely. They made sure we were completely satisfied before leaving. Thank you to the team at Factory Direct, especially Tony and Max, I would recommend them if you are looking for windows and doors, they have excellent prices.”

Works efficiently and maintains cleanliness

“I highly recommend FactoryDirect because they did an outstanding job. It all started with Sasha’s excellent presentation, followed by Sveta’s detailed estimation. Despite the numerous changes I requested, Sveta always remained pleasant and provided great service. Eugene measured my windows accurately, and Anthony and his crew were exceptional. They worked efficiently, cleaned up after themselves, and were punctual and friendly. Their teamwork was like a well-oiled Swiss watch. I’m truly grateful for their incredible work. The pricing was also unbeatable after comparing with others. Do yourself a favour and choose FactoryDirect Windows and doors. It’s a company I trust, and I will definitely recommend them to my family and friends.”

When we checked out Selcan, we could see why they’ve been in business for over 30 years. They’ve nailed the art of window and door installation, offering a wide array of services including garage door products and exterior accents like shutters and railings. 

One of the coolest features? Their virtual home design service, where you can preview stunning before-and-after images of your remodel.

We like that they use Energy Star-certified windows and doors that not only slash energy costs but also look great. Plus, the lifetime warranty on many of their products and a 10-year installation guarantee provide a lot of reassurance.

We also love that they offer financing options, which makes it easier to spread out the cost of those high-quality upgrades over time.

Employs a friendly and professional installation team

“We just had all our windows and doors replaced by Selcan. From beginning to end the service was excellent. Mario took the time to give us all the information we needed. And the installation process went perfectly. The group of men that came were friendly and very professional. I would definitely recommend Selcan to my family and friends.  A BIG THANK YOU!!!!!!”

We stumbled upon Basco during our research, and honestly, we were surprised by what we found. They might be a newer company compared to some of the big names out there, but don’t let that fool you – these guys are doing some seriously innovative stuff.

Their RENEW service blew us away. Instead of shelling out tons of cash for brand-new windows, they can restore your existing ones to like-new condition. It’s a win-win: you save money and help the environment at the same time. 

We were also amazed by their extensive list of services. Whether your windows are foggy, have broken parts, or need a good caulking, these folks can help you.

Plus, their extensive inventory of parts and mechanisms means any repair or upgrade is swift and seamless.

We also loved their user-friendly online platform. It makes requesting quotes, scheduling services, and exploring tailored solutions incredibly easy. 

Measures windows professionally and knowledgeably

“I had a large window over the staircase replaced- the company explained everything from the first call. The man who came to measure was professional and knowledgeable. The two men who came for the installation were efficient, super clean and came on time as arranged. I am extremely pleased with the service and product!”

Remains helpful and responsive during the pandemic

“I’m very happy with the level of service this business provided. At the beginning of the pandemic, I didn’t know how I would be able to replace the glass in all my windows. This work was needed desperately and there weren’t many options available. Basco was very helpful and responsive to my needs and was able to pull off the installation within the government restrictions. Nice group of people, I would recommend them to anyone who asks.”

When we checked out Alumalco, it was easy to see why they’re a favourite for European-style aluminium windows and doors. They have an impressive lineup, from large lift-and-slide doors to bifold systems and modern windows that can transform any home’s look and feel.

We had a chance to chat with the folks at Alumalco, and let’s just say they’re a passionate bunch. They’re all about pushing the boundaries of design and innovation.

We geeked out over their tilt-and-turn windows (seriously, the engineering on those things is mind-blowing) and their insanely efficient insulated folding doors.

They also don’t make you jump through hoops to get information. Their website is a breeze to navigate, and they offer free online quotes – no pressure, just information.

You can even schedule a virtual consultation to get all your questions answered without having to leave the comfort of your home. 

Makes new homes even more special

“We had Alumalco windows and sliding doors installed in our newly built house, and we are absolutely thrilled with both the quality of the windows and the exceptional service provided. From the initial consultation to the final installation, the team at Alumalco was professional, knowledgeable and incredibly helpful. The installation crew was efficient and worked diligently, ensuring every window was installed to perfection. The windows have added a beautiful and modern touch to our house, and also offer excellent insulation, significantly improving the energy efficiency of the house. What truly impressed us was the follow-up by Anthony, the owner of the company, who checked in to ensure everything was perfect and addressed any minor adjustments promptly. I highly recommend Alumalco for anyone in need of high quality windows and exceptional service. Thank you Alumalco for making our new home even more special.”

Handles large windows that other companies couldn’t

“Terrific service from start to finish.  I did a major renovation of my home which lasted several months. I reached out to  10 windows companies and Alumalco came out as my #1 pick (7 of the companies couldn’t do the large windows I wanted regardless).  Alumalco was one of the few companies that I dealt with during my renovations which was flawless from beginning to end.  No headaches, no surprises, a very professional team, highly recommended.  I expect to see Alumalco tags on my neighbour’s windows very soon once they see the job they did at my house.”
