How Installing Energy-Efficient Windows in Brentwood Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:

• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 152 pounds per year on average.
• Save on power bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save around $435 annually on your energy bills in Brentwood.

Estimated Cost of Window Replacement in Brentwood

When looking into window installation, each company provides varying services and costs. Let's look at some typical costs and services.

How Much Do New Windows Cost?

Typically, Brentwood homeowners can expect their window installations to range from $250 to $1,200. The average cost is at about $600. How much it will cost you depends on several factors, including the location of your home, type, number of windows, size, material and more.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Brentwood homeowners $435+ a year after replacing single-pane windows.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using 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?

Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're not sure which kind of window installation service you need, your installer should be able to help you out. Typically, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Brentwood

The EcoWatch Reviews team differs from most reviewers, as we're examining these companies through a sustainability lens. We have reviewed the best window installation companies in Brentwood mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don't have positive feedback about their service from a certain installer, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers won't always provide the most quality service. Still, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
