Work Requests From Portsmouth, NH
Vicinity of Concord Way in Portsmouth
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.
Vicinity of Taft Road in Portsmouth
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!
