We recently had two skylights, original to our 24 year old home, replaced by Skylights Unlimited. We were very impressed. Dennis explained all the options to us and didn't up-sell. The work was done promptly. The installers were on time and couldn't have been more helpful. The work was completed in a day as promised, with everything cleaned up and all the waste removed. They also provided photos of the finished installation, since we were unlikely to venture onto the roof to check, which seemed very thoughtful. The price was very competitive (given other estimates we received), but the service and care taken went to the next level. We wouldn't hesitate to use them again. Highly recommended.

Living in a semi detached and having the bathroom on the adjoining wall meant no natural light for the bathroom. Skylights unlimited provided options (skylight vs suntunnel), cost and timing. Plus they had lots of good reviews. Everyone was timely and very pleasant to deal with. The crew was respectful and tidy. I love the light that the 14 tunnel brings into the room. Great job all around.

Better job done than my photography, but I think you get the idea.

I called this company for repairing a broken sun tunnel.
The owner of the company inspected the site.Gave me the repair options,cost,advantages,disadvantages in each case.
I a few week,after I agree the work to be performed,they sent a fantastic crew to do the job.
The did it fast,very clean,covered the carpets and floors.
The work done,left the sun tunnel installation better than the original contractor installation.
Price was very competitive.
Very pleased with the work performed.

Great workmanship and professional (and entertaining) site crew. Superb install fit and finish with a unique trapazoidal skylight tunnel design, optimizing a challenging existing roof/ceiling arrangement. Estimated work schedule and cost met expectations.
Highly recommended service.

Dennis got back to us very quickly. Estimated 3 weeks to install but were able to do in 2. Arrived when promised. 3 major rain storms since installation and no leaks. Skylight very energy efficient.

When it comes to natural light coming in from the roof I gotta go with Denis and the crew at Skylights Unlimited Markham every time.

The keep it tight and get it right.

My experience is excellent from point of inspection to point of completion. Everyone was respectful, and professional.
They understood their trade and were able to educate.
They showed up on time and worked hard.
I would definitely have them back to do more work if necessary - like when the remaining 2 skylights need to be changed.

Had a Velux venting skylight installed in my master bathroom by Skylights Unlimited. Pretty much everything about this install was about as perfect as it could possibly be. Denis and the office were excellent at returning calls and emails in a timely fashion. They made useful recommendations up front and answered all my questions throughout the process. Ed, my lead installer was both entertaining and extremely knowledgeable. The installers came on time, were courteous, clean, and gave me confidence that they knew what they were doing. They have been doing these for decades and it shows. Although my skylight was a simple single install, I’d trust these guys on the most complex job. The finished product looks amazing. Based on reviews, they also stand behind their work after the initial install. Do your research as I did....you will find that Skylights unlimited in the premier skylight installer in the GTA. Thanks Denis & team.

As soon as I met Dennis I knew I was in good hands. He explained exactly what the crew was going to do and how they were going to do it. He answered all my questions and the quote was competitive.

The crew arrived on time and made a very difficult installation look easy. They were clean, organized and very professional.

We were referred to Skylights Unlimited from a longtime friend in Toronto who were in the process of having a skylight installed by them. Months later, we decided to replace our old skylight which couldn't be repaired, and called SU in the middle of the winter, before the pandemic hit. We got a good explanation of what was happening, a fair quote, left a small deposit, and waited to be scheduled. Then the pandemic hit. We waited patiently for them to call, and they did at the first opportunity to do the work. They did all the work outside, maintained social distance, told us how long it would take, and did the job well and on time. We've been totally happy throughout the process. We wouldn't hesitate to recommend them to anyone needing this done.
