We specialize in condo caulking in Montreal!

We specialize in working with condo unions to provide quality caulking services and products tailored to their needs. Condo caulking may only be one percent of the facade, but it is an integral part of protecting 100 percent of a homeowner’s investment in a property. Although these areas represent an extremely small percentage of building construction, billions of dollars are spent repairing and replacing the building envelope. Whether it’s a townhouse or a high-rise building, it’s important to remember that sealants may be invisible, but they should never be forgotten!

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!
