How Installing Energy-Efficient Windows in Lanham Saves You Money

By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $283 annually on your energy bills in Lanham.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 249 pounds.

Estimated Cost of Window Replacement in Lanham

When considering window installation, each company provides varying services and prices. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

Generally, Lanham homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost is based on several factors, like material, the location of your home, type, size, number of windows and more.

Whether or not you opt for 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 $283 a year on your energy bills in Lanham.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services companies offer: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window replacement company should be able to help you figure out what’s best for your needs. In Lanham, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s good to have a professional assess your frames and window sills.
