Historic Federal Hill Home — Complete Repipe
Preserving historic architectural integrity while completely modernizing water delivery requires scientific diagnostics. Our master technicians deployed non-destructive acoustic sensors behind 100-year-old lath and plaster walls.

Upfront Fair QuotesFailure Analysis & Structural Threat
A 1920s Federal Hill row home with 100% galvanized steel pipes. Internal corrosion had reduced water pressure by 70% and was leaching heavy rust and lead particles into the potable water supply.
Engineering Diagnostics & Execution
Full 3-day PEX-A expansion repipe. Acoustic pipe mapping identified 14 hidden branch points without opening plaster walls unnecessarily. All historical fixtures retained original positions. Post-repipe water lead testing was 100% clear on day 4.
Technical Specifications & Methodology
- Type: PEX-A Cross-linked Polyethylene with ASTM F1960 cold-expansion fittings
- Pressure baseline before: 18 PSI at second-floor bathroom fixtures
- Restored hydrostatic dynamic pressure: 58 PSI continuous across all 3 levels
- Lead and particulate level: 0.000 mg/L verified via EPA-certified laboratory test
Governing Codes & Scientific Standards
Complete home repiping can be executed in historic properties with zero aesthetic damage through strategic manifold placement and non-invasive acoustic routing.
