For a standard-sized home in Cornwall, a full window replacement typically ranges from $8,000 to $20,000, depending on the number of windows, materials (vinyl, wood, fiberglass), and energy efficiency features. Pennsylvania's climate, with its cold winters and humid summers, makes investing in ENERGY STAR® certified windows with low-E glass and argon gas fills highly recommended for long-term savings on heating and cooling bills. Always get 3-4 detailed, written estimates from local, licensed installers to compare.
Yes, Cornwall homeowners must comply with the Pennsylvania Uniform Construction Code (UCC). While a simple like-for-like window replacement often doesn't require a permit, any structural change to the opening, or work on historic properties, likely will. It's crucial to hire a contractor familiar with Lebanon County and Cornwall Borough permit processes who will handle this for you, ensuring compliance with state energy conservation and safety codes.
