How Installing Energy-Efficient Windows in Redmond Saves You Money

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

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Redmond, that’s about 271 pounds per year on average.
• Save money on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
• Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Redmond

Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the average costs and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

Typically, Redmond homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will make your project cost more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star estimates that switching out the windows on your Redmond home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations require 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 significant deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re unsure which kind of window installation service you should get, your installer can assist you. Typically, the decision depends 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 Redmond

In our search to make your home improvements easier and more eco-friendly in Redmond, the EcoWatch Reviews team evaluated many companies before landing on these. Along with energy efficiency, we reviewed window companies all across the state and ranked them based on the following methodology:

Service Area

Since this is a guide for Redmond, we only included companies that serve the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Redmond.

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you opt for. 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 very important review factor. If the majority of customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
