WindowsServices by E&K Contracting

Drafty, inefficient windows are one of the biggest sources of energy loss in older homes. E&K Contracting specializes in replacement window installation that dramatically improves your home's comfort, appearance, and energy efficiency. Whether you're replacing a single failed window or every window in your home, we deliver expert installation with minimal disruption.

We offer a comprehensive selection of vinyl and composite replacement windows from trusted manufacturers, including double-hung, casement, picture, slider, and specialty shapes. Our windows feature Low-E glass, argon gas fills, and insulated frames that meet or exceed ENERGY STAR requirements for Pennsylvania's climate.

Our installation teams are meticulous — every window is leveled, shimmed, insulated, and sealed to prevent air and water infiltration. We respect your home and your schedule, protecting interior floors and walls during installation and cleaning up completely before we leave.

Frequently Asked Questions

Common questions about our windows services.

How much can new windows reduce my energy bills?+
Homes with older single-pane windows can see energy bill reductions of 15–40% after replacing with ENERGY STAR qualified double-pane windows. The savings depend on your home's current windows, insulation, and heating/cooling system.
How long does window replacement take?+
A typical full-home window replacement for an average-sized home (10–15 windows) is usually completed in 1–2 days. Individual windows can be replaced in just a few hours.
Do I need to be home during window installation?+
Yes, we ask that a homeowner or authorized adult be present during the installation so we can confirm window placement and operation meets your expectations.
What's the warranty on replacement windows?+
Most of our window products come with lifetime limited warranties covering glass failure, manufacturing defects, and frame issues. We'll review the specific warranty terms during your estimate.
Can you match windows to my home's existing style?+
Absolutely. We carry windows in dozens of colors, grid patterns, and configurations to match historic, traditional, and contemporary homes throughout Bucks and Lehigh counties.
Is there an ENERGY STAR tax credit for new windows?+
Yes. Federal tax credits may be available for qualifying ENERGY STAR windows. We can help identify which products qualify and provide the documentation you'll need for your tax return.
