There are a number of factors to consider when choosing the right window for your home. Neponset Valley Construction is a certified window contractor in MA. We provide our customers with new vinyl windows that are engineered to last with multi-chamber construction, 100% virgin vinyl for a true-white color, top of the line block and tackle balances that never need adjustment and the convenience of tilt-in sashes.

Some people fear that replacing their windows will cause the look of their house to change. This is not the case. Our professional carpenters can replace your windows with a pine or oak interior that will give you the same look and feel of an older window, with the thermal efficiency of a newer window. Being an experienced window contractor we can give your house a completely new appearance with a custom bow or bay window.

  • Tilt-in windows allow for easy cleaning.
  • Top of the line block and tackle balance systems operate smoothly and never need adjustment or lubrication.


  • Sleek design allows for maximum glass area and less bulky appearance.
