How Installing Energy-Efficient Windows in Westminster Saves You Money

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

  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
  • 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Save money on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
  • Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 460 pounds.

Estimated Cost of Window Replacement in Westminster

Let's take a look at the cost of replacing your windows and the types of services offered by installers.

How Much Do New Windows Cost?

On average, Westminster homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will add extra costs to your project.

It's important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Westminster homeowners $375+ a year when replacing single-pane windows.

Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the full window, including the sill, trim and frame. Pocket installations (or retrofits) entail 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 likely need a full-frame installation instead.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Westminster, the decision will mostly depend on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Westminster

In our search to make your home improvements easier and more eco-friendly in Westminster, the EcoWatch team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Westminster and assigned rankings based on the following methodology:

Service Area

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

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends 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 reflects the quality of services across nearly every category, including warranty, professionalism, quality of parts, quality of installation, cost and more.

Cost

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

Warranty

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

Years of Experience

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

Westminster, CO Window Replacement FAQs

How much does a window install cost?

The national average cost to replace a single window is about $600 but can range between $200 and $1,200, depending on several factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What kind of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

Can you install your own windows?

If you're handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don't have the time or experience, we recommend hiring a professional.

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

Even though you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, it shouldn't be raining, since rain can make the installation harder.

When is it time to replace your windows?

Windows usually last 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.
