Before you hire in South Lyon

Mid-century and newer systems

Most homes here date from 1991 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 South Lyon building department before work starts.

How to compare blower door testing quotes

  • Ask whether the test is a single measurement or includes leak finding.
  • Ask whether they check gas appliances for safe venting first.
  • Confirm the report format you need for code, a rebate or a sale.
  • Ask about BPI or RESNET credentials and when the equipment was calibrated.
  • If they also sell air sealing, ask for a free or included retest.

Cost depends on home size, whether it is a standalone test or part of a full energy audit, whether a test out after air sealing is included, combustion safety checks, and whether a utility or rebate program covers part of it. Someone also needs to be home to give access.
