When to Replace Your Windows

Even the highest quality windows don’t last forever. Watch for these signs that indicate it’s time to replace your windows:

  • The frames are rotten: Wood windows are especially susceptible to rotting if you don’t maintain them properly. Rotten frames are unsightly and can cause mold problems.
  • The 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. Regardless, if your windows don’t work, their days are numbered.
  • Your energy bills are rising: 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 higher than you would like, replacement windows will certainly help.
  • 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with a different aesthetic or operating style: When the time comes for a home makeover, your windows may simply be too outdated to stay.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 them gives you the chance to install larger, more stately windows that operate the way you prefer.

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that vinyl windows are susceptible to yellowing and cracking in the sun, your sources aren’t wrong – they’re simply outdated.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!

Benefits of Replacement Vinyl Windows

With various window materials to choose from, what makes vinyl the right choice for your DC-area home? Consider everything you get when you opt for vinyl windows:

  • 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 efficiency: 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.
