How Installing Energy-Efficient Windows in Milpitas Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, including:

• Save money on electricity bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, the switch can help you save around $671 annually on your energy bills in Milpitas.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
• 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 due to their ability to filter out damaging UV rays.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.

Estimated Cost of Window Replacement in Milpitas

Let's take a look at the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

On average, Milpitas homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at around $600. How much it will cost you varies based on several factors, such as the location of your home, size, material, type, number of windows and more.

It's also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Milpitas home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Something else that affects the total cost is the material of the frame you pick. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Milpitas, the choice will mostly depend on how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Milpitas

EcoWatch reviews are different from other reviews since we evaluate these companies through a sustainability lens. We've assessed the top window installers in Milpitas mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Milpitas, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Milpitas.

Work Quality

When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have positive things to say about their experience with a certain installer, 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 the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Milpitas' climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Milpitas window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
