Lockland Window Cost Calculator

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

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

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 Lockland Saves You Money

When you switch to energy-efficient windows, you may see several benefits, such as:

  • Better temperature control in your home: Residing in a very cold city like Lockland can often mean relying on your heater to keep your home cool. Energy-efficient windows can cut back on how hard your heating system needs to work to heat your home.
  • Save on electricity bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll use 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, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. 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 Lockland

Windows come in different shapes, styles and purposes, so costs and services will vary greatly based on your project. Below, we detail the average cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

On average, homeowners in Lockland can expect that most window installations will cost between $250 and $1,200, with the average cost at about $600. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.

It's important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Lockland homeowners $312+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. 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 with wood fibers encased in plastic also offer 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?

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

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation entails replacing a window without taking out the whole frame, which is generally less expensive than a full-frame installation.

If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Lockland, the choice will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Lockland

EcoWatch reviews are different from most reviews because we evaluate these companies through a sustainability lens. We have evaluated the top window installation companies in Lockland mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Lockland, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Lockland.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window 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

We analyzed trends in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, warranty, cost, professionalism and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try 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

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
