How Installing Energy-Efficient Windows in Wellington Saves You Money

There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Wellington, that’s about 460 pounds per year on average.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Wellington

Let’s go over the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

Generally, Wellington homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at about $600. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $522 a year on your energy bills in Wellington.

How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

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 usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your professionals will replace the whole window, including the trim, sill and frame. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company can recommend the best type for your project. In Wellington, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Wellington

EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. We have assessed the top window installers in Wellington mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty 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 right window installation company near you.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured on this list to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of installation, cost, warranty, quality of parts and more.

Cost

This one is a give-and-take: as with most services, cheap window installers won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Wellington, CO Window Replacement FAQs

How much does window installation cost?

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

What are the most common types of replacement windows?

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

Can I replace my own windows?

Even though you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

Should I replace all my windows at once?

If you want to get more efficient windows and save money on your energy bills, replacing all your windows at once is the only way to gain that benefit. On the other hand, if you have only a few windows that are broken or drafty, you can replace just those.

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 be a two-day job — or more — if you need to have a lot of windows installed.
