Custom Concepts installed new James Hardie siding and GAF roof ventilation at the gutters. New GAF roof and gutters. New Marvin windows. Replaced the deck surface with Fiberon material and the railing with AZEK material. Custom Concepts is an excellent company to work with. The owners, Danny and Mike, are clearly knowledgeable about home construction. They have installed James Hardie siding(replacing 1950 installed wood siding), replaced my roof, replaced my deck surface and railing, and install new windows. Anyone looking to use James Hardie siding should contact them for an estimate. They know what they are doing with this product. I previously have had Hardie installed on my addition and it was not installed properly. The roof, new gutters, new windows look great. In particular, the deck looks fabulous. The office team is great to work with. Everyone is very polite and they answer emails promptly. Based on other estimates that I got for the above projects, I believe they are very competitive.
