How Installing Energy-Efficient Windows in Mount Rainier Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could benefit you:

  • Save money on energy bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $283 annually on your energy bills in Mount Rainier.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • More efficient energy use in your home: Because the winters can get very cold in Mount Rainier, homeowners usually rely on their heater during that time. Energy-efficient windows reduce the amount of heat that is lost through your windows, which makes it easier to keep your house warm.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Mount Rainier

Let's take a look at the cost of replacing your windows and the types of services you may need for your home.

How Much Do New Windows Cost?

According to our market research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. How much it will cost you is based on several factors, like type, material, the location of your home, number of windows, size and more.

It's also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your Mount Rainier home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Something else that affects the overall cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two types of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations are simpler and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Mount Rainier, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Mount Rainier

In our search to find the most reliable, eco-friendly window installers in Mount Rainier, the EcoWatch team chose the above companies as the best window installation companies in the city. We've decided to assess the best window installers in Mount Rainier primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Mount Rainier, we gave more points to companies that cover the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Mount Rainier.

Work Quality

When choosing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive things to say about their experience with a certain installer, it won't be featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Mount Rainier, MD Window Replacement FAQs

How much does window installation cost?

The national average cost of installing one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is generally influenced by the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What kind of window is the best for energy efficiency?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

Can I install my own windows?

Even though you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window replacement company can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

Should I replace my windows all at once?

If you're upgrading your windows to save on your energy bills, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are damaged or leaky, you can replace just those.
