How Installing Energy-Efficient Windows in Lafayette Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to consider making the switch:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Lafayette, that’s about 460 pounds per year on average.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Lafayette

When looking into window installation, each company offers different services and costs. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Although the average cost to install one window is around $600, it can range anywhere from $200 to $1,200. How much it will cost depends on several factors, like the location of your home, material, type, number of windows, size and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Lafayette home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Something else that affects the overall cost is the material of the frame you pick. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

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

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which kind of installation you should get, you can talk to your provider and get their recommendation. The choice mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Lafayette

In our hunt to make your home improvements easier and more eco-friendly in Lafayette, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

Since this is a guide for Lafayette, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Lafayette.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company 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 might be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of installation, warranty, quality of parts, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies won’t always provide the highest quality service. On the other hand, 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

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

Years of Experience

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

Lafayette, CO Window Replacement FAQs

How much should a window install cost?

The average cost to replace one window ranges between $450 and $650. There are many factors that affect the price, such as the number of windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are, your property’s location and the materials used in designing the windows.

What are the different types of windows?

There are several different kinds of windows you can get for your home, including casement windows, double-hung and single-hung windows, awning windows, bay windows, transom windows, picture windows and slider windows.

When should I use a window installation company?

You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a involved process that can be difficult and time-consuming, so it’s best handled by the professionals.

What time of year is a good time to replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.

How long does window installation generally take?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.
