Local context
Split-levels and bi-levels have partly above-grade lower levels, many already finished decades ago with paneling and older carpet. Colonials and larger homes from the 1990s onward usually have full poured basements with sump pumps, ready to be finished from scratch. Radon is common across the Lehigh Valley, so we recommend testing before finishing any basement.
Our scope
Most Bethlehem Township basement projects include some of these.
We remove dated paneling, add insulation and below-grade flooring and rework lighting so the space feels like part of the house.
Full basements allow family rooms, offices, gyms and guest rooms. We plan the layout around beams, ductwork and the sump.
We test first and coordinate a mitigation system when needed, with the piping planned into the finished walls.
Dedicated circuits, good lighting and durable flooring make a lower level work for daily use.
Our approach
We design lower levels to match the quality of the rest of the house, with the same trim, lighting and flooring standards upstairs and down.
Questions
If the work involves new framing, electrical or plumbing, yes. Cosmetic updates such as flooring and paint usually do not. We confirm the requirements for your project with the township.
It should stay accessible and, ideally, have a battery backup. We frame an access panel or closet around it so it can be serviced without damaging finished walls.
