Project Overview & Homeowner Objectives in Zelienople & the Harmony Historic District
The charming streets of Zelienople, Harmony, and Evans City, PA boast some of the richest 19th- and early-20th-century residential architecture in Western Pennsylvania. However, renovating a pre-1978 residence near Main Street Zelienople or the Harmony Historic District requires specialized building science. In this whole-house gut renovation of an 1895 Victorian folk house, the homeowners needed to eliminate hazardous lead paint, replace active knob-and-tube wiring and corroded galvanized pipes, level a 2.5-inch center floor sag, and insulate drafty uninsulated brick-and-timber walls while preserving historic millwork proportions.
Property Profile & Pre-Renovation Challenges
Decades of piecemeal alterations had left the home with cracked horsehair plaster over wood lath, unblocked balloon-framed wall cavities that acted as vertical chimneys for winter cold drafts, a 60-amp fuse box, and multiple layers of deteriorating lead-based paint on interior window casings, baseboards, and doors.
Scope of Work & Turnkey Trade Coordination
- Certified EPA Lead-Safe demolition, HEPA air filtration, and safe debris encapsulation.
- Structural floor leveling, sistered joists, and fire-blocked closed-cell thermal insulation.
- Complete in-house electrical rewiring, plumbing repipe, and zoned HVAC installation.
EPA Lead-Safe Protocols, Structural Stabilization & Balloon-Frame Engineering
Certified Federal RRP Lead-Safe Containment
As a certified EPA Lead-Safe Firm performing comprehensive whole-home remodeling, Dependable Home Solutions isolated each floor using 6-mil polyethylene containment barriers, heavy-duty magnetic zipper doors, and commercial HEPA 99.97% negative-air scrubbers before disturbing a single square foot of painted plaster or trim. All demolition debris was misted, sealed in heavy-gauge bags, and removed safely, followed by HEPA vacuuming and wet-wipe verification.
Structural Leveling, Fire-Blocking & Closed-Cell Insulation
With the interior stripped to the rough-sawn studs, our framing crew used synchronized hydraulic jacks to lift the sagging center girder over a 10-day period, sistering 2×10 structural joists with structural construction adhesive and through-bolts. Because historic balloon framing allows air and fire to travel directly from the cellar to the attic inside open stud bays, we installed solid 2x dimensional fire-blocking at every floor line and sealed the exterior walls and sandstone foundation rim joists with 3.5 inches of closed-cell spray foam—locking out Connoquenessing valley winter winds.
In-House Mechanical Overhaul & Historic Millwork Reproduction
200-Amp Electrical Rewire, PEX-A Repipe & High-Efficiency HVAC
Having all mechanical trades in-house eliminated months of subcontractor delays. Our electricians removed every inch of brittle cloth-wrapped knob-and-tube wiring, installing a new 200-amp Square D QO panel, whole-house surge protection, and AFCI/GFCI circuits. Our plumbers replaced rusted galvanized lines and cast-iron stacks with a quiet PVC drain system and an Uponor PEX-A home-run manifold, while our HVAC crew installed a 96% AFUE two-stage furnace with custom low-profile ductwork.
Custom Millwork & Zelienople / Harmony Code Compliance
After hanging and Level-4 finishing 5/8-inch drywall, our finish carpenters replicated the home’s original 5.25-inch high-profile poplar baseboards, corner plinth blocks, and window stools—delivering historic charm backed by modern PA UCC code compliance.
