Glen Rock Is Our Home — We Know These Homes
Insulation and Home Performance Services in Glen Rock
We offer the full range of insulation and home performance services for Glen Rock-area homeowners. Every project starts with a diagnostic assessment, so our recommendations are based on your specific home rather than assumptions.
Attic Insulation
Glen Rock's older homes, particularly the 19th-century worker housing along Argyle Avenue, Valley Street, and Junior Street, tend to have significant attic insulation deficiencies. We install blown-in fiberglass, cellulose, batt, spray foam, and mineral wool to bring your attic to the correct R-value for Pennsylvania's climate, and we always air-seal before adding insulation.
Wall Insulation
Many of Glen Rock's historic homes were built without wall insulation or with materials that have long since degraded. The dense, semi-detached worker housing along Argyle Avenue and the older homes on Cottage and Glen Avenues are common candidates for wall insulation upgrades. We inject insulation using minimally invasive methods that do not require opening walls or removing drywall.
Crawl Space Insulation
Older homes throughout Glen Rock, including many of the properties on the hillside streets and in the historic district, have vented crawl spaces that allow moisture and cold air to affect the living space above. We insulate and encapsulate crawl spaces to seal out moisture, stabilize floor temperatures, and reduce energy loss from below. It is one of the most impactful upgrades available in older Pennsylvania construction.
Basement Insulation
Rim joist and basement wall insulation reduces cold drafts at floor level and improves comfort on the floors above. Glen Rock's older homes, many of which have stone or brick foundations, benefit consistently from this upgrade. It is a cost-effective project that pairs well with attic and air sealing work.
Air Sealing
Air sealing is the most important step in any home performance project, and it is the one most contractors skip. We include it in every job because properly sealed air gaps are what allow insulation to perform as designed. Glen Rock's older construction, with its plaster walls and knob-and-tube-era framing, often has significant air leakage that a blower door test makes visible.
Home Energy Audits
A blower door test and thermal imaging scan tell us exactly where your home is losing energy. Audits start at $100-$150, are often rebate-eligible through PPL or UGI, and let us give you specific recommendations instead of general ones. For Glen Rock homeowners in older homes, the results are almost always illuminating.
