How Installing Energy-Efficient Windows in North Potomac Saves You Money

There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

  • Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in North Potomac

Each window replacement company offers varying services and has different prices depending on a few factors.

How Much Do New Windows Cost?

On average, homeowners in North Potomac can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. How much it will cost depends on several factors, including number of windows, type, size, material, the location of your home and more.

Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $294 a year on your energy bills in North Potomac.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step when considering a window replacement is to figure out whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the full window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot or deterioration. These installations are more involved and will increase overall costs. Pocket installations are on the simpler end and won’t cost as much, as 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 unsure which window installation service you need, your installer can assist you. In general, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in North Potomac

EcoWatch is different from most reviewers, as we’re examining these companies through a sustainability lens. We’ve evaluated the top window installers in North Potomac mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve North Potomac so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company included in our guide to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, cost, warranty, quality of installation, quality of parts and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

Because of North Potomac’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of North Potomac window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

North Potomac, MD Window Replacement FAQs

What is the typical cost to replace windows in a home?

The national average cost of replacing a window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is typically dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window is the best?

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

What do window installers do?

Window installation professionals go to your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.

What time of year is a good time to replace my windows?

Though you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, it shouldn’t be raining, because rain can make the installation more difficult.

How do you know it’s time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
