How Installing Energy-Efficient Windows in St Clair Saves You Money

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

• Protect your valuables from fading: When you upgrade to energy-efficient windows with 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• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
• Save on power bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in St Clair

Windows come in varying shapes, purposes and styles, so costs and services will vary considerably depending on several factors. Below, we detail the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

According to our market research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. How much it will cost you depends on several factors, like type, the location of your home, number of windows, size, material and more.

It's important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save St Clair homeowners $374+ a year when replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, 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 provide 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?

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

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the whole window, including the sill, trim and frame. A pocket installation involves replacing a window without replacing the frame. So, instead of taking out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're still trying to decide which kind of installation you need, you can ask your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in St Clair

EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. We have evaluated the top window installers in St Clair mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for St Clair, 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 St Clair.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company on this list to ensure its contractors are well-qualified and that the company has gotten lots 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 experience with a certain window installation company, it won't be featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we gave higher scores 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 have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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