How Installing Energy-Efficient Windows in Lafayette Saves You Money

There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • 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 on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save $457 a year on your bills.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Lafayette

Windows come in different purposes, styles and shapes, so costs and services will vary remarkably depending on several factors. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

According to our market research, the typical cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost is based on several factors, including number of windows, material, the location of your home, size, type and more.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $457 a year on your energy bills in Lafayette.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer 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?

In general, there are two types of window installation services you can get: full-frame and pocket installations.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, 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 find the most reliable, eco-friendly window installers in Lafayette, EcoWatch examined many companies before settling on these. Along with energy efficiency, we evaluated several window installers in Lafayette and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Lafayette so you can find the right window installation company near you.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, quality of parts, warranty, professionalism, quality of installation and more.

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 points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a considerable investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Lafayette, CO Window Replacement FAQs

What is the average cost to replace windows?

The national average cost of installing one window is around $600 but can range between $200 and $1,200, based on several factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

There are several different types of windows you can get for your house, such as double-hung and single-hung windows, picture windows, transom windows, slider windows, awning windows, bay windows and casement windows.

Do I really have to use a window installation company?

You should use a window installation professional whenever you want to upgrade your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best handled by the professionals.

When is the best time of year to replace windows?

Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure 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 it usually take to install windows?

Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
