"Declan and his team were extremely professional. Communication was great . The quality of their work was top notch. Originally Pro Build was contracted to replace only the deck boards and stair structure. After demolition it was clear to me that most of the deck structure would need to be replaced. The cost of the additional work was fair and reasonable. I am very pleased with the entire experience. The finished deck is now very well built and looks great. I would hire them again without hesitation."

With over 40 years combined experience, we provide complete Basement remodeling and finishing services with Free estimates and no-nonsense pricing. We will give you the Basement you've always wanted by transforming your previously unfinished Basement into a usable and comfortable living area you can be proud of. We are known for constant communication and on-site project management.

"Our experience with Basic Basements was great from start to finish. Gail, the scheduling coordinator, was very responsive and helpful every step of the way keeping us informed about what work was going to be done next. John, our project manager, was great and made sure all the work was completed efficiently and on time. The work crews coming in and out were outstanding. They were very respectful of our home, worked nonstop until the work was finished, and did an excellent job cleaning up every day. The biggest, and only, headache we encountered was waiting for inspections from our town, which is completely out of Basic Basements' control. We are very pleased and would 100% use them again."
