What Homeowners are Saying…

I love my old “Canadienne” house, but my energy bills were so high that I thought about selling it. A friend has recommended me your services and I thank him for it. You have managed to greatly improve the insulation, my heating costs have fallen by 30%. I’m keeping my house and it’s thanks to you.

M. TREVILLON - LAVAL

I met with several companies before making my choice and I know that with you I made the right one. You have kept your promises. My insulation is much better, the price was respected, your guys worked neatly. I am fully satisfied, thank you to all your team.

M. NADEAU - MASCOUCHE

I have done business with LG4 insulation to improve the insulation of my basement and I am fully satisfied with the experience. They gave me good advice, the work was done to perfection and I got a great deal. If I still need this type of service I will not hesitate for a second, I will do business with them for sure.

MME JULIEN, LAVAL

We have a 50s house and I had never worried about whether it was contaminated with asbestos. Your specialists took samples and confirmed that we had zonolite insulation. Your team intervened quickly and in less than 48 hours the decontamination was completed. I sleep better now that this problem is solved, thank you!

M. ET MME SURPRENANT - REPENTIGNY

How simple it is with you, what happiness! Only one call and one of your guys came to us. He looked at everything to offer us solutions to solve our neighbour’s noise problems from above. We don’t hear footsteps anymore, or their conversations and we are no longer obliged to listen to the same channel as they do, so we don’t  go crazy. I now have the pleasure of relaxing in my couch to hear only my life. A big thank you, it was fast and very effective, it was worth it.

M. RODRIGUE - SAINTE-THÉRÈSE

Certifications and Attestations

When it comes time to choose a qualified contractor, make sure you make the right choice. If the price is too good to be true, it may well be that the contractor is not qualified or has no legal certification. Savings that will only bring into question the proper decontamination of your home if you happen to sell it.
