How Installing Energy-Efficient Windows in Middletown Saves You Money

When you switch to energy-efficient windows, you may see several perks, including:

  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • More efficient energy usage in your household: Because the winters can get very cold in Middletown, homeowners often depend on their heater a lot. Energy-efficient windows lower how much heat is lost through your windows, which makes it easier to keep your house warm.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on power bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll require less energy to heat or cool your home.

Estimated Cost of Window Replacement in Middletown

Each window installation company offers various services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

On average, homeowners in Middletown can expect that most window installations will range from $250 to $1,200, with the average cost at about $600. But costs will vary significantly depending on the current condition of your home, your location, the quality of your products and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.

Whether or not you want to install 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 $294 a year on your energy bills in Middletown.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from 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?

There are typically two kinds of window installation services: full-frame and pocket installations.

Full-frame installations require replacing the whole 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 a great amount of rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

Your window installation company should be able to help you figure out what's best for your needs. In Middletown, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Middletown

The EcoWatch Reviews team differs from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Middletown and ranked them using the following methodology:

Service Area

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

Work Quality

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

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don't have good feedback about their service from a certain company, it won't be featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

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

Middletown, MD Window Replacement FAQs

What is the average cost to replace windows?

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

What are the most common kinds of replacement windows?

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

When should I use a window installation company?

Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, the weather should be dry, because rain can make the installation harder.
