We had the pleasure of having Neal Gosselin at our home to replace the Masonite siding that had been on the house way too long. What he started out was plain just plain awful what he left behind is very close to a work of art. The house looks absolutely wonderful. Neal is a true professional. He made a point of explaining what was going on when asked and did so in English. He was very responsive to our needs, like for hose reels and the back door awning. I'm seriously hopeful we can get him back next year for a couple of doors. We had 5 different contractors give us quotes. Neal was the one that sealed the deal and I'm very happy.

Neil, Conrad and Matthew went well above and beyond what was expected of them. They did an amazing job with siding our home. They where friendly and worked in a timely manner. Everyday they cleaned up as if the job was done which was impressive. The attention to detail is what really hit home with me. It is always the little things that mean the most and the finishing touches with the light fixtures and the numbers on the house is what made the house a home to us. I would highly recommend them to anyone. Thanks guys we really appreciate you making our house a home.

Imagine doing business with a firm that arrives on time, finishes when promised, and does quality work! That's my experience with Gosselin. Plus, there was no non-sense with the price. The quote was it, period. Got three quotes and theirs was the lowest. They installed windows and doors and did some sliding repair. Combined with excellent products and superb installation, Gosselin represented a great value. Neil and Conrad are honest guys. I recommend Gosselin, highly.

Neil was fantastic from start to finish. He walked us through the entire process from the different types of siding and accessories as well as the color options. We initially had him in for a quote and were unable to do the work - we called him almost 2 years later and were able to just pick up where we left off. We made changes along the way - adding windows, a new front door and siding for a couple of out buildings - he got everything we wanted and got the job done when he said he would.
Besides making our house look absolutely fabulous, Neil and his crew were all super friendly and wonderful. We were sad when the job was done and we weren't going to see them on a daily basis! I would highly recommend hiring C Gosselin Siding for any home improvements and siding you need.
