What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the complete window, including the sill, trim and frame. A pocket installation involves replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

If you’re still trying to decide which kind of installation to get, you can talk to your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Great Falls

EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Great Falls area so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, warranty, cost, quality of installation, professionalism and more.

Cost

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

Warranty

As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven 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.
