I fully recommend the service of Demolex to anyone looking for insulation work. The upgrade that was done for me went above and beyond. The price was reasonable and in my opinion you can not find a better contractor to do your insulation work.

Advice, price and timeline were fair – exceeded our expectations in fact. Sergey from Demolex worked hard to stay within our budget – he was more concerned at keeping the price reasonable than we were! If you have soundproofing and insulation needs Demolex gets our recommendation for sure.

This is the first time that I have posted an on-line review of work done for me by a contractor. I’m doing so on the BBB website because previous reviews submitted to the BBB web-site were the deciding factor in my choosing Demolex General Contracting to upgrade my home’s insulation. Demolex’s representative, Surgey, fulfilled all of his commitments relating to the job. And the cost of the job was within the quote even though he blew in more insulation than required by the quote. Surgey was punctual, courteous and conscientious. He took obvious pride in doing a professional job. He didn’t leave until ensuring that I was totally satisfied. I can, without hesitation, recommend Demolex.

Demolex installed blown insulation in my attic and soundproofing between some open walls. They provided great service. The job site was kept clean, the staff were super knowledgeable. The price was fair — great work!

We had cellulose insulation blown into our attic by Sergey and his assistant. The job was completed efficiently and there was virtually no mess left behind. I would definitely recommend Demolex to anyone requiring insulation services.

We contacted Demolex to provide a competitive quote for the removal of old insulation in our attic space this last September. The business owner came over the next day and provided very thorough insight to the job and cleanup. His quote was very fair and his professionalism made Demolex the obvious choice for us. The job was done on time and the crew left our home perfectly clean. Our contractor on site observed the Demolex work and promptly requested quotes for other homes they were working on.

A routine re paint of our children’s room had us remove all the furniture from the room… Then we felt the floor… Cold… Very cold…. And drafts with air coming up and through the newly laid laminate we installed last summer. How could there be cold air through a floor? This turned a weekend paint job into a demolition. Removing the laminate and then cutting open the subfloor we were shocked that no insulation or vapour barrier was ever installed in the home when it was built in ’78…. With three children who need their bedrooms, we took action. Of course it’s Saturday…. Having a 4′ hole in the floor of each room for the next few days was not an option. A quick search of insulation companies brought up many operators specializing in the installation / specialization of blown in cellulose… All with answering services or office times beginning Monday. Calling Demolex we were surprised to get an answer on the third ring by the contractor himself. He was available to discuss the situation immediately and provided insight, his cell # for directions to our home and provided an estimate based on his questions determining our needs. Within three hours he arrived to our home, prepared with all the materials and equipment required. Two hours later he was complete. The job wasn’t a big one in the grand picture and having the holes / floor open already helped. The cellulose not only insulated the home but provided a much needed noise reduction between our children’s bedrooms and our living room/kitchen below. The contractor also provided the option of bringing help for the job, or asking if we would be the help to reduce our costs. Thinking ourselves DIY amateurs we elected to help. The company was knowledgeable, educational and provided insights into the best way to reinstall our flooring for maximum benefit. As far as we were concerned we should have been charged for all of the above! Demolex is a professional, personable, experienced company that worked with us (not advising or telling us what needed to happen with our home) and educated us every step of the way. It’s rare to recommend a contractor now-a-days, we recommend Demolex to anyone whom needs a job done (and done 100%) in a pinch! We will be using them again once we get to the master bedroom too! Wonder if he knows a great drywall contractor too with the same professionalism?! Thank you
