How Installing Energy-Efficient Windows in Lafayette Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could help you:

  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Better temperature control in your home: When you reside in a place like Lafayette where the summers can get quite hot, you usually need to rely on your air conditioner to keep your house cool. Energy-efficient windows can cut back on how much cool air is lost through your windows when cooling your home.
  • Save money on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $457 annually on your energy bills in Lafayette.

Estimated Cost of Window Replacement in Lafayette

Windows come in various purposes, shapes and styles, so costs and services will vary greatly based on several factors. Below, we detail the average cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

According to our market research, the national average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost varies based on several factors, such as number of windows, material, type, size, the location of your home and more.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Lafayette homeowners $457+ each year after replacing single-pane windows.

Another factor that influences the total cost is the material you select for your frame. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning an installation is to decide whether you should get a full-frame or pocket installation.

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window replacement company will be able to help you understand what's best for your needs. In Lafayette, the decision will mostly be based on how old your home is and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Lafayette

EcoWatch is different from other reviewers, as we look at these companies through a sustainability lens. We've assessed the best window installation companies in Lafayette mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can reduce your energy 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 installation companies that serve a wide variety of states and cities so you can find the best 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 of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive feedback about their experience with a certain window installation company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Lafayette's climate, homeowners will want to mitigate rot, low efficiency and water damage. 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 typical cost of installing a single window can range between $450 and $650. There are several factors that affect how much it costs, including the materials used in designing the windows, how energy-efficient the windows are, your property's location, the number of windows, local labor costs and styles and sizes of windows.

What are the types of windows?

The most common types of windows for homes include: awning windows, picture windows, casement windows, slider windows, double-hung and single-hung windows, transom windows and bay windows.

When do I have to use a window installation company?

Unless you're handy and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer alternative.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation harder.
