How Installing Energy-Efficient Windows in Twin Lakes Saves You Money

By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:

  • Save on energy bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $453 annually on your energy bills in Twin Lakes.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: In Twin Lakes, you can reduce your indirect greenhouse gas emissions by about 460 pounds per year when you switch to energy-efficient windows.
  • 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Twin Lakes

Windows come in various shapes and sizes, so costs and services will differ remarkably. Here are the average costs and the primary services that you'll find from window installers.

How Much Do New Windows Cost?

Although the typical to replace a single window is about $600, it can range anywhere from $200 to $1,200. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which have a higher price tag.

Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends if 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 more efficient.

What Services do Window Installers Offer?

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

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Twin Lakes, the decision will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Twin Lakes

EcoWatch reviews are different from other reviews, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve Twin Lakes so you can find the right window installation company near you.

Work Quality

When picking 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 choose. 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

Customer feedback is another very important review factor. If most customers don't have good things to say about their service from a certain company, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Twin Lakes, CO Window Replacement FAQs

How much should a window install cost?

The national average cost to install a single window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What are the types of windows?

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

What do window installation companies do?

Window installation professionals visit your home to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation.

How long does it usually take to install windows?

Each window takes around 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
