Find the Right Window For Your Climate and Budget

There are several options for windows, and each comes at a different price point.

The most popular materials for windows include:

  • Wood – The most expensive of these three materials, wooden windows also require the most maintenance and upkeep. Since wood can be prone to rotting, it has a shorter lifespan than synthetic materials.
  • Vinyl – The most popular window material on the market, vinyl replacement windows are affordable, colorful, and durable.
  • Fiberglass – Fiberglass and composite windows can be treated to look like wood. Why not opt for the real thing? Fiberglass window options are the most durable material on this list and are slightly less expensive than a wooden frame.

Besides the material, other factors that will affect the installation cost of your windows include:

  • Brand
  • Window size
  • Glass type
  • Finish

Beyond the upfront window glass replacement cost, it’s important to consider how their glass type and finish will affect your utility bills in the long term. Replacing your windows can save you up to 15% on energy bills—but only if you select the right materials for your area.

Glass Type and Energy Efficiency
When you’re home window shopping, you’ll notice they have labels with several inscrutable numbers.

To make the right purchase, get familiar with the following factors:

  • U-factor – This number describes how readily the window absorbs non-solar heat. If you live in a cooler environment (or one with cold winters), you’ll want to make sure your heat won’t readily pass through your windows back out into the world! Look for a low U-factor. Conversely, if you live in the desert, a high U-factor could help keep your home cool.
  • SHGC – The solar heat gain coefficient (SHGC) rating describes how much a window absorbs solar heat. If you live in a hot environment, look for windows with a lower number so that your house doesn’t cook on long summer days.
  • Finish – Your windows’ glazing also affects its energy efficiency. Windows with 3-coat Low-E are better for hot environments, while windows with 2-coat Low-E can help keep your home toasty in cooler climes.

Keep in mind that you may need more than one kind of window type in your home. If your south-facing living room heats up in the sun, it will need different windows than your shady second-floor office.

Replace When The Weather Is Nice

Once you’ve selected the right windows for the job, it’s time to contact a professional window installer! If your go-to contractor is booked up for months, you may be tempted to wait until his calendar opens up in January.

But unless you live in Miami, this isn’t the best idea.

While replacing windows can be a quick and straightforward process, your home will be exposed to the elements for anywhere from a couple of hours to a couple of days. In rainy or cold weather, this can risk damage to the rest of your property, not to mention sky-high heating bills.

Many people wait until spring to replace their windows. But the right time for your project is any month when it’s comfortable inside your home without turning on the heat or AC.

If You Want, Go Window-By-Window

No one said that you have to replace all your windows at once. If it’s not in your budget or you don’t want to turn your kids’ bedrooms upside down, feel free to extend the process for as long as you need.

Try one of the following methods:

  • Start by replacing the windows that face the road to give your house a fresh new face
  • Replace the windows in the rooms you use most frequently (bedroom, kitchen)
  • Replace standard-sized windows first, saving expensive custom sizes for later

The first step is getting started. Once you see the benefits of a brand-new window, you can make a decision about when you want to replace the next.

Installation Matters

When installation day comes, it’s important to work with a trustworthy local professional.

Beyond getting a fair price and tidy work product, your window’s installation will affect you for years to come.

  • Windows that are not properly installed may let in moisture, drafts, or noise
  • As a result, you’ll experience higher energy bills
  • Your windows may also have a shorter lifespan

Prepare Your Home

Hopefully, you’ve found a licensed and bonded professional to install your windows.

What do you have to do to prepare your home for their visit?

  • Remove curtains, blinds, and curtain rods
  • Take paintings and art off the adjoining walls
  • Notify your alarm company of the work and disarm any relevant alarms
  • Roll up or remove rugs
  • Move your furniture three feet away from the wall and cover with a dropcloth
  • Place valuables in unaffected rooms

Then, let the professionals take it away. It’s only a matter of time until you’re enjoying your beautiful new windows!

Check the Warranty on Your New Windows

How long will your windows last?

When you’re purchasing your windows, make sure that they come with a warranty. This will give you a sense of how long your new windows might last. Be aware that some low-cost windows come with lifetime warranties. While the manufacturer may replace a faulty window, you’ll have to pay for the labor!

To extend your windows’ lifespan, perform basic upkeep tasks:

  • Clean your interior windows monthly
  • Power wash exterior windows yearly
  • Resealing or repaint wooden frames as needed

Keep your eye on your new windows for any issues like moisture, foggy glass, or difficulty opening. If you notice a problem while your window is still under warranty, get in touch with your window manufacturer.
