20 Best Window Companies in Daly City, CA (2025 Reviews)

How Installing Energy-Efficient Windows in Daly City Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:

• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
• Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save money on electricity bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save about $440 annually on your energy bills in Daly City.

Estimated Cost of Window Replacement in Daly City

Windows come in various purposes, shapes and styles, so costs and services will vary considerably based on your project. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

Typically, Daly City homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. Costs will differ significantly depending on the number of windows you need, the quality of your products, the current condition of your home and your location. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.

It’s also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Daly City home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by switching to energy-efficient windows depends 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 expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step of a window replacement is to clarify whether you need a full-frame or pocket installation.

Full-frame installations entail replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has significant deterioration. Because these installations are more involved, they will increase the total cost. A pocket installation involves replacing a window within the old frame. This means instead of tearing out the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Daly City, the choice will mostly depend on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Daly City

EcoWatch reviews differ from most reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

Because this is a guide for Daly City, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Daly City.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, cost, quality of parts, quality of installation, professionalism and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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