Window repair and installation in Buffalo


Home windows play an important part in interior insulation and exterior appearance. They last anywhere from 15 - 30 years or more before showing signs of wear and tear, at which point you should consider home window repair or replacement in Buffalo.

If you live in an older home in neighborhoods like Elmwood Village, Parkside or West Village, you’re more likely to need window repair or replacement. If you feel drafts nearby windows, hear more outside noise than usual, have trouble operating your windows, notice flooring or furniture starting to fade or are suddenly seeing an increase in spending on heating or cooling, your windows likely need attention.

Some home window conditions are repairable. If you need replacement, two of the most common options are full-frame replacement windows or replacement window inserts. Full-frame replacement windows are necessary if you need new exterior framing, allowing you to choose a new style or size. Replacement window inserts fit into existing frames and maintain your current style, size, trims and siding.

Some of the factors to consider when choosing your window type include:

  • Energy efficiency: Efficient windows will keep heat out in the summer and inside in the winter, reducing your energy costs year-round. ENERGY STAR-certified windows lower energy bills by an average of 12 percent nationwide. Replacement windows with an NFRC label help you compare measures like U-Factor, Solar Heat Gain Coefficient, Visible Transmittance and Air Leakage.
  • Window style: Changing window style? There are lots of types. Common options include double-hung, awning, casement, sliding, picture and bay/bow. Each operates differently and has distinct appearance and ventilation characteristics.
  • Materials: Framing materials are usually wood, aluminum, vinyl or composite. They differ in their ability to stop heat transfer and their durability and maintenance requirements.
  • Glass style: Multiple panes of glass, safety glazings and sound reduction are all available with replacement windows in Buffalo.

How much does window replacement cost in Buffalo?

Buffalo residents spend, on average, $300 - $1,000 for home window replacement per window. The exact amount you pay depends on several variables:

  • Window style: Double-hung windows are common and the most affordable of popular home window styles. Bay and bow windows and highly customized windows are the most expensive.
  • Materials: Wood and fiberglass cost more than aluminum or vinyl.
  • Energy-efficiency options: Expect to pay more for triple-pane windows and other efficiency options, like low-emissivity coating.
  • Window size: Larger, more expansive windows increase material costs and take more time to install, adding to cost.

How to choose a window installer in Buffalo

Buffalo has a large number of home window repair and home window replacement companies. If you are purchasing replacement windows, look for a business that both sells the windows installs them. Verify it has a contractor license on the City of Buffalo website. Buffalo law requires anyone in the home improvement business to be licensed and insured for general liability.

As you search for a contractor, ask these questions:

  • How much experience does the contractor have installing windows in Buffalo?
  • Can the contractor provide a list of references?
  • Does the contractor provide a free, in-home consultation and guaranteed price quote?
  • How does the installation process work? How long will it take? How are installers trained, and are they certified by any professional organizations?
  • Are the windows and installation covered by a long-lasting warranty?

Get at least three estimates before starting home window repair or home window replacement in Buffalo. The contractor should be familiar with permitting requirements in the City of Buffalo and Erie County and whether you need one before work begins.
