Montclair Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Montclair, CA 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 Montclair Saves You Money

By switching to energy-efficient windows, you and your family can benefit in several ways, including:

  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging 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 property if you decide to sell.
  • Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Montclair

Windows come in different shapes and sizes, so costs and services will vary greatly. Here are the typical costs and services that you can find from window installers.

How Much Do New Windows Cost?

Typically, Montclair homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. Costs will vary significantly based on the number of windows you need, your location, the quality of your products and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.

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

How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether 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?

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

Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your installers will replace the entire window, including the trim, sill and frame. A pocket installation entails installing a new window within the existing frame. This means instead of taking out the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still debating which kind of installation you should get, you can consult with your installer and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Montclair

In our search to make your home improvements easier and more eco-friendly in Montclair, the EcoWatch team chose the above companies as the best window installation companies in the city. We’ve evaluated the top window replacement companies in Montclair mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured in our guide to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good feedback about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Montclair, CA Window Replacement FAQs

How much does window installation cost?

The national average cost of replacing one window is around $600 but can range between $200 and $1,200, based on several factors. The price is generally dependent on the size of the window, the type and material of the window and the location of your property. Also, keep in mind 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 kinds of windows?

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

When do I have to use a window installation company?

Unless you have experience with home improvement projects and have all the necessary tools to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.

Should I replace all my windows at once?

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