Mahamat is a cheerful and high professional contractor. He answered my message for assistance within 5 minutes and came the next day right on time. He spent a good 30 minutes surveying the problem (the racoons were making a huge racket) and came back with photos and a highly detailed estimate that showed both the minimum needed to solve the problem and the maximum work needed to bar all possible entry point in the future. He explained the problem and used the pictures to illustrate what he planned to do. He has been in business for 12 years, so we accepted his lifetime warranty and were also impressed by other recommendation on Homestars.
He worked for half an hour longer than he estimated and actually lowered the price when some things proved solvable in more reasonable ways. I found him incredibly polite, knowledgeable, concerned with our issue, and--this is unusual in many contractors--proud of what he does and eager to do it well. I would highly recommend him to anyone.
