A replacement window installation in Grasonville

We install replacement windows that improve energy savings, comfort, curb appeal, security, and require low maintenance!

Are the windows in your house more than 20 years old? Are you uncomfortably cold during the winter when you're standing by a window? If your windows have insulated (double-pane) glass, is there condensation between the panes? Are your windows made of wood that requires painting? Do you have trouble opening, closing or locking your windows?

If you answered "yes— to any of these questions, you might be a candidate for replacement windows.

Get the best in beauty and energy-saving. From initial window measurements to final installation, our skilled installers make sure your new windows look beautiful and perform perfectly.

Installing replacement windows is a major investment, but it's an improvement that homeowners appreciate for numerous reasons.

Here are the major benefits of installing replacement windows:

  • Energy savings. If you replace old single-pane windows with ENERGY STARâ„¢ replacement windows, it's possible to save around $500 per year on heating and cooling costs, according to the Dept. of Energy. Savings will be greatest in the northern regions with cold winters.
  • Comfort and convenience. Instead of staying clear of drafty old windows, you can move your furniture closer to the view outside. Since your new windows will be easy to operate, you'll use them more often to enjoy natural ventilation.
  • Curb appeal. New windows can really transform a home's appearance. You'll appreciate this benefit while you're in the house and when it's time to sell.
  • Low maintenance. While old-fashioned wood windows required regular painting and even re-glazing, today's top-quality replacement windows are made from materials (vinyl, fiberglass and aluminum) that are super-durable and maintenance-free.
  • More security. The solid, secure locking action on new windows is a big improvement over older window locks.

It's worth explaining that a replacement window is designed and sized to fit inside the frame (jamb) of an existing window.

If the existing window sill, side and head jambs are in good condition, this frame can remain in place. Only the sash units (which contain the glass) are removed, and the replacement window unit is installed in the resulting opening.

Testimonial by Gerald and Robin from Selbyville, DE

We had been taking about needing to upgrade insulation, and immediately we noticed less draft and the heat pump working less.
