How Installing Energy-Efficient Windows in Farmington Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, such as:

  • Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated.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.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Farmington

Windows come in varying shapes and sizes, so costs and services will differ considerably. Here are the typical costs and the primary services that you’ll find from window installers.

How Much Do New Windows Cost?

Though the average cost of replacing a single window is about $600, it can range from $200 to $1,200. How much it will cost varies depending on several factors, like type, the location of your home, size, number of windows, material and more.

Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $358 a year on your energy bills in Farmington.

We recommend getting free quotes from multiple window companies to find the one that works best for your budget.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations involve replacing the entire 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 a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation means replacing a window without taking out the whole frame, which is generally cheaper than a full-frame installation.

Your window installation company will be able to advise you on the best type for your project. In Farmington, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Farmington

In our search to find the most reliable, eco-friendly window installers in Farmington, the EcoWatch team chose the above companies as the best window installation companies in the city. We have decided to evaluate the top window installers in Farmington mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you opt for. 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

Customer feedback is another super important review factor. If the majority of customers don’t have nice things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, 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. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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