Bathroom remodeling in New Hampshire often means a small bath in a cold corner of an older house, or a camp bath that was never meant for daily winter use. Village capes have one bath over a stone foundation. Lakes houses hide the plumbing in a crawl that freezes. Mountain houses add the problem of a long vent through a deep roof. Say whether you are fixing a leak or making a seasonal room livable.
Plaster or dry board, a fan that dumps into the attic, and a floor that bounces are ordinary. Tile that sounds hollow has let go. A window in the shower is a rot path, faster on the Seacoast where the wall is already wet from weather. The ceiling below, or the crawl below, tells you if the pan has failed. Look there before you describe the job as new fixtures only.
Moving the toilet in a camp floor can mean joists you can see from underneath and a septic system you must not overwhelm or break. Keeping the fixtures in place is often the right scope. A tub on a narrow stair in an older village house is a problem on day one. Heat in the room matters. A bath on an outside wall with no radiator will freeze the line you just moved into the cold bay.
Well water leaves stains and odd pressure. A remodel that closes a galvanized branch will look finished until the wall weeps. Septic fields and old tanks in the yard limit what you add. Mention them. If this is the only bath, the house still has to function at night. That limit sets the schedule more than the finish does.
Give the town, the kind of house, and what is under the floor. A soft spot, a slow drain, or a fan that goes nowhere belongs in the call. Say if the building is a camp you are converting to all-year use. Call the number on this page.
