Estimated Cost of Window Replacement in Mandeville

Each window installer offers varying services and has different costs based on several factors.

How Much Do New Windows Cost?

Although the average cost to install a single window is about $600, it can range anywhere from $200 to $1,200. This is because window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, such as 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 installing a new window without replacing the frame. So, instead of taking out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which kind of window installation service you need, your installer should be able to assist you. Typically, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Mandeville, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Mandeville.

Work Quality

We’re willing to bet that you’re looking for a company to do a great 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 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 most customers don’t have positive feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Due to Mandeville’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Mandeville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
