When to Replace Your Windows

Even the highest quality windows don’t last forever. Vinyl replacement windows are an attractive, high quality, cost-effective option. Learn more about the benefits of vinyl windows here.Replacement Windows

Don’t know if your windows need replacement? Watch for these signs:

  • Rotten Frames: Wood windows are especially susceptible to rotting if you don’t maintain them properly. Rotten frames are unsightly and can cause mold problems.
  • Windows don’t work: Perhaps your windows stick when you try to open them, or they’re too loose and continually slide closed. Maybe the frames are warped, so your windows don’t open at all. All of these functionality issues indicate it’s time to get new windows!
  • Rising energy bills: Old, rattling, single-pane windows were inefficient from day one. Even double-pane windows can become drafty and inefficient if the seal between the panes breaks. Either way, if your energy bills are more expensive than you would like, replacement windows will certainly help lower your energy bills.
  • You want windows with a different aesthetic or operating style: When the time comes for a home makeover, your windows may simply be too outdated to stay. Replacing your windows gives you the chance to install different styles that operate the way you prefer.

At Certified Incorporated, we install two top brands of windows:

Atrium is located in a state-of-the-art manufacturing facility in Welcome, NC. They manufacture premium residential vinyl windows and patio doors for distributor customers located predominantly throughout the eastern half of the U.S., serving both new construction and replacement/remodel applications.

Benefits of Replacement Vinyl Windows

With various window materials to choose from, what makes vinyl the right choice for your Maryland, Washington, DC or Virginia-area home? Consider everything you get with vinyl window replacements:New Window Installation in Living Room

  • Low cost: Vinyl is usually the lowest-cost window material you can find, making it more affordable than fiberglass, aluminum, and wood windows.
  • Low maintenance: Unlike wood, which requires occasional sanding and staining, vinyl is virtually maintenance-free.
  • Durability: Vinyl doesn’t rot, chip, discolor, peel, or sag, even with direct exposure to the harsh elements. This means you can expect vinyl replacement windows to last 20 years or more.
  • Energy efficient: Vinyl is a natural insulator, making it a great window frame material. Paired with efficient glass, vinyl window frames can compete with the efficiency ratings of any other window.

History of Vinyl Windows

Vinyl is one of the most popular window materials available today. It was first introduced in Germany in the 1950s as a replacement for wood and aluminum windows, which were in short supply following WWII. The low-cost material migrated to the US in the 1960s, and it has only grown in popularity since.

Early vinyl windows weren’t without problems. If you’ve heard that vinyl windows are susceptible to yellowing and cracking in the sun, your sources aren’t wrong – they’re simply outdated. Today’s extruded vinyl windows have color going all the way through. You may not be able to paint vinyl windows without voiding the warranty, but you can expect whatever color you choose to last!
