How Installing Energy-Efficient Windows in Alameda Saves You Money

When you switch to energy-efficient windows, you may see some benefits, including:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
• Save on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of residential energy use. Installing energy-efficient windows can help reduce that number, which helps you save $531 a year on your bills.

Estimated Cost of Window Replacement in Alameda

Each window installation company offers varying services and has varying price points depending on several factors.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. This is because window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $531 a year on your energy bills in Alameda.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the total window. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: it’s not uncommon for homeowners to 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 while leaving the existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re unsure which type of window installation service you need, your installer should be able to advise you. Typically, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.
