Very professional and numerous team for large-scale work. Special thanks to Audrey who was able to listen to me and offer me a new date for work, despite a long vacation. Congratulations also for the ease and clarity of requests for estimates, for the transparency of estimates, as well as for the guarantee of work superior to other caulking companies. I highly recommend Calfeutrage MJM & Fils.

The MJM team were outstanding.From the initial estimate to the finished product.MJM were professional and polite and did not talk down to me. They took the time to explain what they were doing and did what they said they would do.They use top of the line product and when they are done clean up after themselves so you wouldn't even known they were there.I highly recommend MJM.Don't mess around this is the protection of your investment get MJM to do your caulking.MJM made caulking my home, a nice, easy painless experience.

Fantastic company!!! They are very professional, knowledgable and punctual. I can say without a doubt that this company by far is my best experience with any company that I have ever dealt with. I would highly recommend MJM et fils services! I am completely satisfied and will refer them to my friends. They are truly a team that works hand in hand. There was no clean up after they did it all.

The whole team was amazing. Came on time and did their work.Out of all the companies I called 4 companies and all told me send them picture we will send you a estimation. 4 companies later no call back no text no email. Calfeutrage mjm et fils being my 5th company I called. They answered the phone, texted, emails.told me step by step what they would do and kept me in the loop the whole time. Customer service and quality of work is their motto. Would recommend again!
