How Installing Energy-Efficient Windows in Welby Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:

  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: In Welby, you can cut your indirect greenhouse gas emissions by about 460 pounds per year when you install energy-efficient windows.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
  • Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you need less energy.

Estimated Cost of Window Replacement in Welby

When looking into window installation, each company provides different services and costs. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range from $200 to $1,200. Costs will vary considerably depending on your location, the current condition of your home, the quality of your products and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.

It’s also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Welby home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We recommend getting free quotes from multiple window installers to find the one that works best for you.

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 necessary when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the entire window, including the frame, trim and sill. A pocket installation involves replacing a window within the old frame. So, instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which window installation service you should get, your installer can advise you. In general, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

We have evaluated the best window replacement companies in Welby 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 lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers 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 the best window installation company near you.

Work Quality

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

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 service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window companies may not provide the highest quality service. Still, 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. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Welby, CO Window Replacement FAQs

What is the average cost to install windows?

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

What are the most common types of replacement windows?

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

Can I install my own windows?

If you’re handy and know how to replace a window, you may be able to install your own windows. But if you don’t have the time or know-how, we recommend hiring a professional.

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

While you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, it shouldn’t be raining, because rain can make the installation harder.

When is it time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
