Brookside Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Brookside, DE using our customized window cost calculator.

Estimated Window Cost:

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Brookside Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change 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 fade less because of their ability to filter out harmful UV rays.
  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
  • Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Brookside, that’s about 299 pounds per year on average.

Estimated Cost of Window Replacement in Brookside

When considering window installation, each company offers varying services and costs. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

According to our market research, the average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. How much it will cost is based on several factors, including material, number of windows, size, type, the location of your home and more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material you choose for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using 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 provide decent insulation for your home.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. 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 Brookside, the decision will mostly be influenced by the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Brookside

In our hunt to find the most reliable, eco-friendly window installers in Brookside, the EcoWatch Reviews team examined many companies before deciding on these. Along with energy efficiency, we reviewed several window installers in Brookside and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Brookside area so you can find the best window installation company near you.

Work Quality

When selecting new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher 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 the majority of customers don’t have nice 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 want to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. 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.

Brookside, DE Window Replacement FAQs

What is the typical cost to install new windows in a home?

The typical cost of replacing a window can range between $450 and $650. There are several factors that influence the cost, including your property’s location, how energy-efficient the windows are, local labor costs, styles and sizes of windows, the materials used in designing the windows and the number of windows.

Which kind of window should I get?

A window’s energy efficiency is affected by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

When do I have to use a window installation company?

Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.

How long does window installation usually take?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed during a typical 8-hour work day.
