How Installing Energy-Efficient Windows in Hillsborough Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, including:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Save money on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll require less energy to heat or cool your home.
- Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Hillsborough
Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
Even though the average to replace one window is about $600, it can range from $200 to $1,200. These estimates vary depending on the specifics of your installation, like material, size, the location of your home, type, number of windows and more.
Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $652 a year on your energy bills in Hillsborough.
Getting free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first step of a replacement is to decide whether you should get a full-frame or pocket installation.
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation involves installing a new window within the old frame. So, instead of taking out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which type of window installation service you should get, your installer can assist you. In general, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Hillsborough
In our hunt to find the most reliable, eco-friendly window installers in Hillsborough, the EcoWatch Reviews team examined many companies before settling on these. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
Because this is a guide for Hillsborough, we only included companies that serve the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Hillsborough.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company in our guide 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
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Hillsborough's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Hillsborough window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Hillsborough, CA Window Replacement FAQs
How much should a window install cost?
The typical cost to install one window ranges between $450 and $650. There are many factors that influence how much it costs, which include how energy-efficient the windows are, the number of windows, styles and sizes of windows, the materials used in designing the windows, your property's location and local labor costs.
What are the most common types of replacement windows?
The most common kinds of windows for homes include: picture windows, slider windows, transom windows, bay windows, double-hung and single-hung windows, awning windows and casement windows.
Can you replace your own windows?
Even though it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How long does it generally take to install windows?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
Should I replace my windows all at the same time?
If you're upgrading your windows because of energy-efficiency, replacing all your windows at the same time is the only way to gain that benefit. On the other hand, if you have just one or two windows that are broken or leaky, you can replace just those.
