Allstate Home Improvement Services: Quality Replacement Windows and Expert Installation

Windows
Allstate H.I. offers window replacement services in Smithtown and the rest of Long Island. Trust the Allstate H.I. crew to help you find the best windows for your home and install them according to the highest industry standards, all at a reasonable value.

Is It Time to Replace Your Windows?

Timing is the secret to getting the biggest bang for your window replacement buck. You’ll know it’s time for you to get new windows when:

  • They’re visibly damaged.
  • They’re difficult to open or close.
  • They’re letting in drafts or outside noise.
  • They’re difficult to clean.
  • They’re hurting your home’s curb appeal.

It’s also a good idea to get your windows replaced if you want a more energy-efficient home, if you’re thinking of putting your home up for sale, or if you can see visible signs of UV damage in your carpet, furniture, and window treatments.

Beauty. Functionality. Value.

At Allstate H.I., we only install windows that are engineered to perform. We carry products from top U.S. manufacturers, all protected by the industry’s best warranties. Our inventory offers a variety of glass packages and a wide range of decorative options. Window styles include:

  • Single and double-hung windows
  • Sliding windows
  • Casement and awning windows
  • Bay and bow windows
  • Picture windows
  • And more!

Whatever your price range, our sales representatives will guide you through the selection process and help you make an informed choice about your windows. No high-pressure sales tactics; just plain old service.

Give the Allstate H.I. team the chance to earn your business. You’ll be glad you did!
