Before you hire in Columbus Township

Mid-century and newer systems

Most homes here date from 1992 or later. Original furnaces, water heaters and roofs from that era are well past their service life, so replacement planning matters more than repair.

Michigan basements

Freeze-thaw cycles and clay soils make foundation cracks and wet basements common across Metro Detroit. Foundation and sump pump checks belong on every spring list.

Permits: check with the Columbus Township building department before work starts.

Air Sealing in Columbus Township: FAQ

It depends on house size and age, how many leaks there are and how easy they are to reach, testing, materials, and whether it is bundled with insulation work.
Usually yes. Older homes often have large hidden leaks at the attic floor and basement rim joists, and sealing them reduces drafts and helps new insulation perform.
A tighter house needs working exhaust fans and properly venting appliances. A careful contractor checks combustion safety and ventilation after sealing.
