What we promise, we deliver.
No marketing jargon. Just 4 concrete commitments you can verify at every service call.
1-year written warranty
Every service is covered by a 1-year warranty on parts and labor. No 'verbal warranty' here — you leave with a signed document.
Fixed price before service
The quote you sign is the final price. No surprises, no hidden fees, no 'oh by the way we also need to change this'. We discuss everything upfront.
Same technician, always
No anonymous subcontractors. The technician who diagnoses is the one who comes to your home. He knows your file, he knows your door.
Repair before replacing
We do not sell new doors. Our job is repair. If we can fix your problem for $200 instead of selling you a $4,000 door, we do it. That is our ethic.
What our clients really say
No AI-generated reviews. No fake accounts. Here are real testimonials from Montrealers who called us.
"My 1987 patio door would not open without a sumo-worthy battle. The technician changed the rollers in 40 minutes, showed me the worn part, and explained why the track was deformed. Honest, fast, and he took the time to answer my worried-grandmother questions. 5 well-deserved stars."
"I contacted 4 companies before them. Two never showed up to appointments. A third tried to sell me a new door for $4,200. DFPRO changed the thermos for $340 tax included. My view of the maple tree is clear again. Thanks for respecting the budget."
"Video diagnosis Sunday evening at 8 PM. Response at 8:28 PM. Service Tuesday morning. The door now glides like new, and I saved $180 compared to another company's quote. The Swiss knowledge of waterproofing is felt in the quality of the work."
"Good job on the roller repair and weatherstrip replacement. The technician went slightly over the 30-minute scheduled time, but he did a full door inspection and found a track issue we had not seen. I prefer someone meticulous to someone rushed."
"First experience with a repairman who explains IN FRENCH what he is doing. My English-speaking partner and I both understood the problem. The 1-year warranty is reassuring, especially knowing how unforgiving the Montreal winter is on doors."
"I have lived in Brossard for 6 years and called 3 different companies for my patio door. This is the first time the problem does not come back after 6 months. The Belgian waterproofing experience shows: no more drafts, no more fog between the panes. It is definitively fixed."
