How Installing Energy-Efficient Windows in East Renton Highlands Saves You Money

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

• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky.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 real estate value.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In East Renton Highlands, that’s about 271 pounds per year on average.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in East Renton Highlands

Each window installation company provides varying services and has different prices depending on several factors.

How Much Do New Windows Cost?

On average, East Renton Highlands homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at around $600. Costs will differ considerably based on the number of windows you need, the current condition of your home, your location and the quality of your products. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.

It’s also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star estimates that upgrading the windows on your East Renton Highlands home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

What Services do Window Installers Offer?

When it comes to window replacements, there are typically two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the entire 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 damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in East Renton Highlands

In our hunt to find the most reliable, eco-friendly window installers in East Renton Highlands, the EcoWatch team evaluated dozens of companies before landing on these. Along with energy efficiency, we analyzed 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 a wide variety of states and cities 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 featured in our guide to make sure its contractors 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 good things to say about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as 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 considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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