Many benefits of replacing your windows

  • Fewer drafts: Single-pane windows are often drafty and they are the least energy efficient. New windows are built better to reduce drafts and greatly improve the comfort of your home year round.
  • Less maintenance: Old painted windows require regular maintenance. New windows made from vinyl or a composite are not only durable, they're also maintenance-free, never need to be painted and are easier to clean.
  • Reduced noise: New windows can not only reduce the amount of sound entering your home from outside, but they can also reduce the amount of noise that comes out of your house.
  • Energy savings: Replacing your old, drafty single-pane windows with ENERGY STAR® qualified energy-efficient windows can save you as much as $500 annually on heating and cooling costs.
  • Added security: Most new windows are tested for forced entry and are designed with multiple locks to improve the safety.
  • Enhanced curb appeal: New windows can improve your home's appearance - inside and out. There are many window styles and trim styles available to compliment the architecture of your home and your personal style. If you're thinking about putting your home on the market, new windows are a good selling point.

Vinyl windows in a variety of styles

We know that choosing the right styles and material for your windows is just as important as the installation. That's why Sentry Windows and Doors offers a wide array of different windows styles including double-hung, casement, bay & bow, picture, sliding windows and more!

Sunrise Restorations Window Systems

Restorations Innovative Window Systems from Sunrise Windows offer a unique narrow-line window design emulates the look of traditional windows. To make this narrow line window strong, energy efficient, and maintenance free, we married PVC with Fiberglass and created a material called FiberCore - an all-new way of making a window. The internal core of the extrusion is made of a pultruded core of fiberglass, because it's stronger than PVC, metal or wood, and is extremely thermally efficient.
