How Installing Energy-Efficient Windows in Lochearn Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:

  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
  • Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 249 pounds.

Estimated Cost of Window Replacement in Lochearn

Windows come in all shapes and sizes, so costs and services will differ considerably. Here are the typical costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

Generally, homeowners in Lochearn can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. These amounts vary depending on specific characteristics of your installation, such as size, material, the location of your home, number of windows, type and more.

It’s also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that switching out the windows on your Lochearn home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material you pick for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive 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 step of an installation is to decide whether you need a full-frame or pocket installation.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without taking out the complete frame, which tends to be cheaper than a full-frame installation.

Your window replacement company should be able to help you figure out what’s best for your needs. In Lochearn, the decision will mostly depend on the age of your home and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Lochearn

In our hunt to make your home improvements easier and more eco-friendly in Lochearn, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed several window installers in Lochearn and ranked them using the following methodology:

Service Area

Because this is a guide for Lochearn, we only included companies that serve the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Lochearn.

Work Quality

When selecting new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have nice things to say about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as 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 installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Lochearn’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Lochearn window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Lochearn, MD Window Replacement FAQs

How much does a window install cost?

The average cost of installing a single window ranges from $450 to $650. There are a variety of factors that influence the price, including styles and sizes of windows, how energy-efficient the windows are, local labor costs, the materials used in designing the windows, your property’s location and the number of windows.

Which kind of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

Can I install my own windows?

If you’re handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don’t have the time or skills, we recommend hiring a professional.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, it’s most likely time to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
