Carlisle’s historic streets, thriving arts scene, and easy access to I-81 make it one of the most desirable places to live in the Cumberland Valley. Whether you dream of a ground-up estate on rolling acreage or a sympathetic remodel of a century-old downtown townhouse, WSL Incorporated turns vision into reality with true design-build precision, transparent pricing, and craftsmanship refined over thirty years in Central Pennsylvania.
Why Carlisle Homeowners Trust WSL Incorporated
Local Knowledge, Regional Muscle
We know Carlisle limestone, Cumberland clay, and the temperature swings that test building envelopes four seasons a year. Our in-house architects, estimators, interior designers, and superintendents collaborate daily so your project sails smoothly through borough permits, historic-district reviews, and HOA approvals.
Award-Winning Craftsmanship
Our work has been featured on regional Parade of Homes tours and praised by clients from Mechanicsburg to Hershey. Every trim joint, energy-efficient window, and smart-home system is installed by crews who treat your investment like their own.
Transparent Process & Pricing
One contract, one schedule, one accountable point of contact. The WSL six-phase roadmap—Discovery, Concept Design, Fixed-Price Proposal, Permitting & Selections, Construction, and Lifetime Care—keeps surprises out of your project and in your rear-yard entertaining space where they belong.
Future-Focused Performance
From insulated concrete forms to solar-ready roofplans, our builds consistently test 40-50 percent tighter than code-minimum homes. That keeps utility bills low and interiors comfortable, summer through blizzard.
Building in Carlisle: What to Expect
Lot selection & zoning: From wooded acreage in South Middleton Township to in-town infill lots, we handle due diligence—easements, setbacks, utility stubs, and municipal water-tap fees.
Historic approval: If your property lies in the Old Town Historic District, our design team prepares elevation drawings and material lists that satisfy the Carlisle Historic Architecture Review Board while preserving modern performance.
Energy code & green upgrades: Carlisle’s 30-degree January lows and humid July highs demand robust insulation, advanced HVAC, proper humidity control, and solar-orientation design. We specify 2 × 6 walls with spray-foam or exterior ZIP-R sheathing, triple-pane windows, and heat-pump water heaters to meet or beat current IECC guidelines.
Timeline:
- Custom home: 8–12 months from contract to keys.
- Major remodel or addition: 4–6 months, depending on structural changes and material lead times.
