How Installing Energy-Efficient Windows in Brentwood Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, such as:
- Save money on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- 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.
- Reduce your carbon footprint: Because 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 Brentwood
Windows come in varying styles, purposes and shapes, so costs and services will differ tremendously depending on your project. Below, we go over the average cost and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
On average, homeowners in Brentwood can anticipate that most window installations will cost between $250 and $1,200, with the average cost sitting at around $600. This is because of the fact that window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Brentwood homeowners $579+ a year after replacing single-pane windows.
Another factor that influences the overall cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the trim, frame and sill. Full-frame installations are necessary 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 increase the total cost. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
If you’re still trying to decide which type of installation to get, you can talk to your installer and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Brentwood
In our hunt to find the most reliable, eco-friendly window installers in Brentwood, the EcoWatch Reviews team evaluated many companies before deciding on these. Along with energy efficiency, we analyzed several window installers in Brentwood and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Brentwood area so you can find the right window installation company near you.
Work Quality
When installing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, quality of parts, quality of installation, warranty, cost and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Brentwood’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Brentwood window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Brentwood, CA Window Replacement FAQs
How much does window installation cost?
The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, depending on several factors. The price is typically influenced by the location of your property, the type and material of the window and the size of the window.

The most common kinds of windows for homes are double-hung and single-hung windows, awning windows, transom windows, casement windows, slider windows, bay windows and picture windows.
Do I really need to use a window installation company?
You should use a window installation company whenever you need to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it’s best left to the professionals.
How do you know it’s time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that have to be installed.
