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 Delaware Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, such as:
- Better temperature control in your home: Energy-efficient windows can lower how hard your heating system needs to work to heat your home.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save $298 a year on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Delaware
Each window installer provides varying services and has different price points based on several factors.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range from $200 to $1,200. These figures vary depending on specific characteristics of your installation, like material, number of windows, size, the location of your home, type and more.
Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $298 a year on your energy bills in Delaware.
Asking for free quotes from several installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first step when planning a window installation is to clarify whether you need a full-frame or pocket installation.
Full-frame installations entail replacing the full window, including the sill, trim and frame. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. Full-frame installations are more involved and will raise overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.
Your window installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Delaware
In our hunt to make your home improvements easier and more eco-friendly in Delaware, EcoWatch landed on the above companies as the top window installation companies in the city. We've decided to evaluate the top window installers in Delaware mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Delaware so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company featured on this list to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have positive feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try 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
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
Due to Delaware's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Delaware window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Delaware, OH Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost of installing a window is around $600 but can range between $200 and $1,200, depending on several factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window should I get?
A window's energy efficiency is affected by a variety 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.
When do I need to use a window installation company?
Unless you're handy and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The process of installing windows 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.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows together is the only way to gain that benefit. However, if you have only one or two windows that are broken or leaky, you can replace just those.
