How Installing Energy-Efficient Windows in McLean Saves You Money

There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 376 pounds.
• Save on electricity bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $359 annually on your energy bills in McLean.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

What Services do Window Installers Offer?

In regard to window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the frame, sill and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot. Because these installations are more involved, they will raise the total cost. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re not sure which type of window installation service you need, your installer can advise you. Generally, the choice is based on 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 McLean

The EcoWatch Reviews team differs from other reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:

Service Area

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

Work Quality

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

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a hefty investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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