What does a home inspection in Wallingford include?

Bob approaches every Wallingford inspection per ASHI and InterNACHI Standards of Practice. With 1900s–1950s housing stock dominant in Wallingford, 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 Wallingford?

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.

What are common issues in Wallingford homes?

Based on 20+ years inspecting early to mid-20th century homes in Delaware County, these are the issues Bob finds most often in Wallingford's 1900s–1950s housing stock:

  • Clay sewer laterals with tree root intrusion and bellied sections
  • Layered electrical upgrades with code violations at old/new connections
  • Oil-to-gas furnace conversions with improper chimney liner sizing
  • Original slate or clay tile roofs reaching end of useful life
  • Plaster-over-lath moisture damage hidden behind intact-looking walls
  • Inadequate insulation and single-pane windows driving high energy costs
