How Installing Energy-Efficient Windows in Lennox Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:

  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • Decrease your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.

Estimated Cost of Window Replacement in Lennox

When considering window installation, each company offers different services and costs. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Though the average cost of installing one window is around $600, it can range from $200 to $1,200. How much it will cost varies depending on several factors, such as material, number of windows, the location of your home, type, size and more.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Lennox homeowners $509+ per year after replacing single-pane windows.

Costs will also vary depending 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 a bit more expensive and offer good insulation. Composite frames made with 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 offer decent insulation for your home.

What Services do Window Installers Offer?

When considering window replacements, there are typically two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot or deterioration. These installations are more involved and will raise the total cost. Pocket installations are simpler and won’t carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re still trying to decide which kind of installation you need, you can ask your provider and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Lennox

In our search to make your home improvements easier and more eco-friendly in Lennox, the EcoWatch team examined dozens of companies before deciding on these. Along with energy efficiency, we reviewed window companies all across the state and ranked them based on the following methodology:

Service Area

Because this is a guide for Lennox, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Lennox.

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 ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: similar to other services, cheap window installers may not provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Lennox, CA Window Replacement FAQs

How much does window installation cost?

The national average cost to install a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the different types of windows?

There are various kinds of windows you can get for your home, such as double-hung and single-hung windows, bay windows, casement windows, slider windows, transom windows, awning windows and picture windows.

Can I install my own windows?

If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don’t have the time or skills, we recommend hiring a professional.

Should I replace my windows all at once?

If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
