How Installing Energy-Efficient Windows in Hillsborough Saves You Money
There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 206 pounds per year on average.
- Save on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- 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.
Estimated Cost of Window Replacement in Hillsborough
When researching window installation, each company offers different services and costs. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
Typically, Hillsborough homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at about $600. These estimates vary depending on specific characteristics of your installation, like material, size, number of windows, type, the location of your home and more.
Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $308 a year on your energy bills in Hillsborough.
Asking for free quotes from multiple providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step of a replacement is to think about whether you want a full-frame or pocket installation.
A full-frame installation is a replacement of the full window. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
Your window installation company can recommend the best type for your project. In Hillsborough, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Hillsborough
EcoWatch reviews are different from most reviews since we evaluate these companies through a sustainability lens. We have assessed the top window installation companies in Hillsborough primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Hillsborough 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 on this list to make sure its contractors 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 nice feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.
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 providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Hillsborough’s climate, homeowners need to be wary of low efficiency, water damage and rot. 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.
