Tom did an amazing job installing our windows. He has done many other repairs at our home as well. He is very thorough and completed the project ahead of schedule. He is courteous and very respectful. We would hire Tom again for any of our house repairs or upgrades.

I ended up hiring them for all of my remodel projects and most likely they will also run my whole house project. They are very responsive, flexible, reasonably priced, communicative and did I say flexible. Highly recommend.

There were a couple of scheduling glitches, and the carpenter had a bit of an attitude issue, but we ended up with a very nice looking final product. Tom came out for the finish-up work and made sure everything was satisfactory. He had suggested a wood/iron combo railing system when he did the estimate, and boy do we like it! It looks just great. Even though Tom was very busy, he clearly cares that all his customers are happy, small job or large.

They fixed our fence and helped us throw our gutter back on the house. Most of the other contractors didn't even call us back! Thanks so much!

Tom came out for a free speedy estimate and was able to tell us within a day what our fencing project would cost us. He was very kind and kept in mind our budget. His crew was out within a few days, promptly disposed of our old materials and have speedily(2 days!) installed 50 feet of gorgeous new fence. Very happy and will definitely hire again.
