Question 1

How much does window replacement cost in Pennsylvania?

Accepted Answer

Window replacement in Pennsylvania typically costs $400–$1,200 per window installed, depending on size, style, and material. Double-hung vinyl windows average $450–$700 each. Premium fiberglass or wood-clad windows run $800–$1,500 each. A typical home with 15–20 windows costs $8,000–$20,000 for a full replacement. Energy-efficient windows may qualify for federal tax credits of up to $600/year.

Question 2

How long do replacement windows take to install?

Accepted Answer

Most window replacements are completed in 1–3 days for an average home. We typically install 5–8 windows per day. Your home stays secure throughout — we never leave openings unprotected overnight. Custom-sized or specialty windows (bay, bow, picture) may have 4–8 week lead times for manufacturing before installation day.

Question 3

What windows are most energy efficient for PA homes?

Accepted Answer

For Pennsylvania's climate, look for ENERGY STAR-certified windows with U-factor of 0.30 or lower and Solar Heat Gain Coefficient (SHGC) of 0.25–0.40. Double-pane windows with argon gas fill and Low-E glass are standard. Triple-pane windows offer better insulation but cost 25–35% more. We help you balance energy savings with budget to find the right fit.

Question 4

Do I need permits for window replacement in Pennsylvania?

Accepted Answer

Most Pennsylvania municipalities require permits when replacing windows, especially if changing the size of the opening or altering the structural framing. A like-for-like replacement in the same opening may not require a permit in some townships, but it varies. In Allentown, Bethlehem, and Easton, permits are generally required. We confirm requirements for your municipality and handle all permit applications and inspections.

Question 5

What's the difference between vinyl, fiberglass, and wood windows?

Accepted Answer

Vinyl windows are the most affordable ($450–$700 installed) and virtually maintenance-free, but color options are limited. Fiberglass windows ($700–$1,200) are stronger, expand/contract less with temperature changes, and can be painted. Wood-clad windows ($800–$1,500) offer the most traditional interior appearance with weather-resistant exterior cladding. For most Pennsylvania homes, vinyl or fiberglass offers the best performance-to-cost ratio.

Question 6

Will new windows reduce my energy bills?

Accepted Answer

Yes — replacing single-pane or older double-pane windows with modern ENERGY STAR units typically saves $150–$500 per year on heating and cooling costs. Pennsylvania's cold winters mean the insulation improvement is significant. Homes with original 1970s–1990s windows see the biggest savings. We can estimate your specific savings based on your current window type and home size during a free consultation.

Question 7

What window styles are best for Pennsylvania homes?

Accepted Answer

Double-hung windows are the most popular in Pennsylvania — both sashes tilt in for easy cleaning. Casement windows (crank-out) provide the best seal against air infiltration, ideal for the Lehigh Valley's windy winters. Picture windows maximize views and light. Sliding windows work well for wider openings. Bay and bow windows add dimension and value to living rooms. We help match window styles to your home's architecture and your functional needs.

Question 8

What warranty do replacement windows come with?

Accepted Answer

Window warranties vary by manufacturer. Andersen offers a 20-year glass warranty and 10-year non-glass. Pella provides limited lifetime on vinyl and wood. Marvin offers a 20-year limited warranty. We install windows from top manufacturers and our labor warranty covers installation workmanship for 5 years. We register all manufacturer warranties on your behalf and provide warranty documentation at project completion.
