How Installing Energy-Efficient Windows in Ellicott City 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 switch are the following:
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Save money on electricity bills: After you switch to 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.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Ellicott City
Each window installation company provides various services and has different costs depending on several factors.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range from $200 to $1,200. How much it will cost is based on several factors, like size, type, number of windows, material, the location of your home and more.
Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
When it comes to window installations, there are typically two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations involve 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 a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're not sure which kind of window installation service you need, your installer can advise you. In general, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Ellicott City
In our hunt to make your home improvements easier and more eco-friendly in Ellicott City, the EcoWatch team assessed dozens of companies before landing on these. Along with energy efficiency, we reviewed several window installers in Ellicott City and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Ellicott City so you can find a quality window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, quality of parts, cost, warranty, professionalism and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Ellicott City's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Ellicott City window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Ellicott City, MD Window Replacement FAQs
What is the typical cost to replace windows?
The typical cost of installing one window can range between $450 and $650. There are several factors that influence the price, such as the number of windows, your property's location, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows and local labor costs.
Which kind of window should I get?
A window's energy efficiency depends on a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
Can you install your own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year is a good time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
How often do you need to replace windows?
Windows generally last about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them checked by an expert to determine if they need any repairs or replacements.
