What does a home inspection in Holmes include?
Bob approaches every Holmes inspection per ASHI and InterNACHI Standards of Practice. With 1920s–1950s housing stock dominant in Holmes, Bob pays particular attention to the era-specific issues that affect early to mid-20th century construction in Delaware County.
Block & Poured Foundations with Clay Laterals
1920s–1940s homes typically feature poured concrete or concrete block foundations — an improvement over stone, but still vulnerable to cracking and water intrusion after 80+ years. Bob pays special attention to clay sewer laterals common in this era, which suffer from tree root intrusion and joint separation.
Early Electrical Upgrades & Oil-to-Gas Conversions
Many homes from this era have had multiple electrical upgrades layered over original wiring — sometimes creating code violations where old and new systems connect improperly. Bob also evaluates oil-to-gas furnace conversions, checking that chimney liners, supply lines, and venting meet current safety standards.
Original Slate Roofs & Plaster-Over-Lath Moisture
Original slate and clay tile roofs from the 1920s–1940s may still be serviceable but require careful inspection for worn fasteners and deteriorating underlayment. Bob checks for plaster-over-lath moisture issues where exterior water intrusion saturates wall cavities behind intact-looking plaster surfaces.
Plaster Walls, Hardwood Floors & Early Insulation
These homes feature quality craftsmanship — hardwood floors, plaster walls, built-in cabinetry — but often lack adequate insulation by modern standards. Bob evaluates whether past insulation retrofits were done properly and checks for moisture trapped behind plaster from exterior or plumbing leaks.
How does mold testing work in Holmes?
Homes from the 1920s–1940s combine aging infrastructure with building practices that create persistent moisture pathways — clay sewer laterals, minimal foundation waterproofing, and plaster walls that mask moisture damage.
Clay sewer laterals with tree root intrusion causing backup and sub-slab moisture
Oil-to-gas conversion furnaces with condensation issues from improper chimney liner sizing
Plaster-over-lath walls that hold moisture for extended periods without visible exterior signs
Basement window wells with deteriorating drainage directing water toward foundation walls
Clear Results & Honest Recommendations
Bob walks you through exactly what the lab results mean — no jargon, no panic. All samples go to a PRO-LAB certified lab with results in 2-3 days. Mold testing starts at $275.
