How Installing Energy-Efficient Windows in St. Helens Saves You Money
There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Save money on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: In St. Helens, you can cut your indirect greenhouse gas emissions by about 271 pounds per year after you install energy-efficient windows.
Estimated Cost of Window Replacement in St. Helens
Windows come in different styles, shapes and purposes, so costs and services will differ considerably depending on several factors. Below, we describe the average cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
Though the average cost to replace one window is around $600, it can range anywhere from $200 to $1,200. But prices vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will make your project cost more.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material you choose for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more involved and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.
If you’re not sure which kind of window installation service you need, your installer should be able to advise you. Typically, the choice is influenced by 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 St. Helens
EcoWatch differs from most reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for St. Helens, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in St. Helens.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, quality of parts, quality of installation, professionalism, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
