Pauline Di La Fonte

I worked with JBC back in August because I wanted to make some small changes to my kitchen. It wasn't a full renovation since I already liked my kitchen and it's in great condition, but the cabinets just weren't my style anymore. I had painted them before, but this time I wanted to install new ones. I was in love with these cabinets that have glass doors and open upward. I showed them my idea and they showed me the available models - thank God one was exactly what I wanted! They installed them and I was blown away by how much it updated my kitchen. It's been a few months now and I haven't had any issues at all. Everything is really high quality.

A few years ago, my husband hired JBC for a flooring project and fumigation, we were impressed with their professionalism. Recently he had them in mind for our latest project, it was a bit bigger we needed a brick retaining wall and a full fence installation. The retaining wall was needed to help prevent soil erosion on our property and the fence was replaced both to update the design and because the old one was worn out. Just like the last time, they did everything perfectly, from planning to execution and the results look fantastic. Now I understand why my husband always wants to work with this company.

A few months ago part of our house got flooded after a pipe burst, it was really a nightmare I didn’t even want to think about it anymore. The drywall and carpet in several rooms were completely ruined, the guest bedroom, living room, study, even the garage. We contacted JBC to help us fix everything, my wife and I were honestly desperate at that point. They removed all the damaged drywall and replaced it, then installed new carpet. I decided to go with a different color, it used to be beige but now it’s light gray, it looks so much nicer. What I liked most is that they worked fast but didn’t cut corners. We didn’t have a single problem working with them, everything went smoothly, I can’t thank them enough
