Local context
Farmhouse cellars here usually have stone walls, low ceilings and dirt or patched concrete floors, and many are better kept as mechanical and storage space. Newer custom homes often have full poured basements, and sloped lots can allow walk-out lower levels with full doors and windows. Pennsylvania has some of the highest radon levels in the country, so we recommend testing before any basement is finished.
Our scope
Most Williams Township basement projects involve some of these.
Sloped lots allow full doors and windows, which makes a lower level feel like a main floor. We detail the exterior so the new openings look intentional.
We test before finishing and coordinate a mitigation system when levels call for one, with the piping planned into the finished walls.
Pressure tanks, softeners and pumps stay accessible behind finished doors or in a dedicated utility room.
A bedroom with a full bath gives visitors a private space. Any sleeping room needs a code-compliant egress window.
Some stone cellars can be finished well. Others are better improved for storage. We walk through it with you before design starts.
Our approach
We tell you honestly whether your basement is a good candidate for finishing before you spend anything on design. When it is, we plan the mechanicals, moisture control and layout together.
Questions
Yes. Radon levels are high across much of Pennsylvania, and installing a mitigation system is far simpler before the walls and ceiling are finished.
Sometimes. It depends on ceiling height, moisture and the condition of the walls. Some cellars finish well, and others are better improved as dry storage. We assess this before you commit to a design.
