How Installing Energy-Efficient Windows in Port Townsend Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, including:

• Save money on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $379 annually on your energy bills in Port Townsend.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
• Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 271 pounds.

Estimated Cost of Window Replacement in Port Townsend

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

How Much Do New Windows Cost?

Though the typical cost to install a single window is about $600, it can range anywhere from $200 to $1,200. These numbers are based on specific characteristics of your installation, such as type, number of windows, the location of your home, material, size and more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

We advise requesting free quotes from multiple window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

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

A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which raise the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window within the old frame. So, instead of removing the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re not sure which type of window installation service you need, your installer can assist you. In general, the decision is based on 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 Port Townsend

In our search to find the most reliable, eco-friendly window installers in Port Townsend, the EcoWatch Reviews team assessed dozens of companies before landing on these. We have decided to review the best window installation companies in Port Townsend mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Port Townsend area so you can find the right 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 company on this list to ensure its technicians are well-qualified and that the company has gotten tons 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 service from a certain company, you won’t see it featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

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