I would like to finish my basement and I would like to talk to someone about the process and the pricing please. Thank you
Project Location: Portsmouth, NH
We have an unfinished basement with a lot of potential. We'd like to have the walls sealed and possibly have the ceiling finished. Our goal is a super organized tool room, a nice clean exercise area, and storage space. We're working on getting it cleaned up and we'd love to find someone who can do this project soon.

We have a dated, semi-finished basement that we would like to finish and divide into a few rooms - family room, office, and possibly add 3/4 bathroom. The basement doesn't take on water (that we know of), but it does run very humid in the summer. We are exploring our options and would like to move forward with the project soon.

We live in a 100 year old home with a damp/wet basement. It's a small space but we'd like to finish it and add a bathroom.
Project Location: Portsmouth, NH
We are looking to add a a master bedroom to our home. We had considered doing a renovation upstairs combining two bedrooms and putting on an addition to replace the absorbed bedroom but we are now thinking it might make more sense to add a bedroom and bath in the basement. We have a partially finished basement. We'd like to make it officially finished and add a bedroom and bathroom down there. Thanks!
