How Installing Energy-Efficient Windows in Landover Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could benefit you:

• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save more on your bills.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Landover

Let’s go over the cost of window installation and the kinds of services you may need for your home.

How Much Do New Windows Cost?

On average, homeowners in Landover can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. These numbers vary depending on specific characteristics of your installation, like number of windows, material, type, the location of your home, size and more.

It’s also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Landover home translates to 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. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Asking for free quotes from several companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the full window, including the sill, frame and trim. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company will be able to help you choose what’s best for your needs. In Landover, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Landover

In our search to make your home improvements easier and more eco-friendly in Landover, EcoWatch examined dozens of companies before settling on these. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Landover area so you can find the best window installation company near you.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer in our guide to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

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