Project Overview & Homeowner Objectives in Zelienople & Harmony

Homeowners across Zelienople, Harmony, and Evans City, PA face two very different wall and ceiling challenges: historic pre-1940 residences near Main Street Zelienople and the Harmony Historic District with sagging, spider-webbed horsehair plaster over wood lath, and newer homes where harsh grazing sunlight from large windows exposes every poorly taped drywall butt-joint and nail pop. In this comprehensive interior surface restoration of a 1915 colonial, our clients wanted to stabilize failing downstairs plaster ceilings, replace water-damaged upstairs walls after a plumbing leak, soundproof a home office, and achieve a glass-smooth Level 5 drywall finish without coating their home in fine white dust.

Property Profile & Pre-Renovation Challenges

Previous patch jobs had left heavy, mismatched swirl textures on the ceilings, peeling corner bead, and plaster keys that had detached from the wood lath—creating a risk of ceiling collapse. Furthermore, pre-1978 painted plaster requires certified EPA Lead-Safe containment before cutting or scraping.

Scope of Work & Turnkey Trade Coordination

• Certified EPA Lead-Safe containment, HEPA air scrubbing, and removal of damaged plaster and lath.
• In-house electrical junction box updates and plumbing pipe insulation inside opened wall and ceiling cavities before board hang.
• Acoustic Rockwool insulation, structural plaster pinning, 5/8-inch drywall hanging, and Level 5 drywall finishing.

EPA Lead-Safe Containment, In-House Mechanical Checks & Acoustic Hanging

Checking Hidden Plumbing & Wiring While Walls Are Open

The advantage of hiring a full-scope general contractor for drywall and plaster work is what happens while the studs and joists are exposed. After erecting 6-mil poly containment barriers and running HEPA air scrubbers under our EPA Lead-Safe Certified Firm protocol, our crew removed the water-damaged ceiling. Before hanging new board, our in-house licensed plumbers replaced the leaking copper elbow that caused the damage and insulated cold-water lines against summer sweat, while our electricians secured buried splice boxes and installed airtight IC recessed LED housings.

Plaster Key Stabilization & 5/8-Inch Sag-Resistant Hanging

In the historic dining room where the original plaster was salvageable, we drilled conditioner holes along structural cracks and fastened perforated plaster washers into the wood lath to pull the sagging plaster back tight before embedding fiberglass mesh tape in high-strength USG Durabond 45 setting compound. In the stripped rooms, we packed the interior walls and ceiling joists with 3-inch Rockwool Safe’n’Sound mineral wool for acoustic privacy, then glued and screwed 5/8-inch sag-resistant drywall using floating perimeter clips at roof trusses so winter Western PA truss-uplift never cracks the ceiling corners.

ASTM C840 Level 5 Skim-Coating & Dust-Free HEPA Sanding

Eliminating Joint Flashing Under Grazing Natural Light

Under standard Level 4 drywall finishing, the porosity difference between bare drywall paper and taped mud joints causes visible “flashing” bands beneath satin paint and large windows. To achieve a true ASTM C840 Level 5 finish, our finishers applied a tight, continuous knife and roller skim-coat of joint compound across 100% of the wall and ceiling surface. Using Festool Planex vacuum sanders hooked directly to HEPA dust extractors—guided by high-lumen raking inspection lights—we delivered mirror-flat walls with zero airborne dust migration into the rest of the home.
