How Installing Energy-Efficient Windows in Shoreline Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to think about making the switch:

• Save on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $366 annually on your energy bills in Shoreline.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
• Reduce your carbon footprint: In Shoreline, you can reduce your indirect greenhouse gas emissions by about 271 pounds per year once you install energy-efficient windows.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Shoreline

Let’s go over the cost of updating your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. These amounts vary depending on specific characteristics of your installation, including type, material, number of windows, size, the location of your home and more.

With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially during the winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Shoreline homeowners $366+ per year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer 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.

Full-frame installations entail replacing the complete window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has considerable damage or rot. Because these installations are more involved, they will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to help you choose what’s best for your needs. In Shoreline, the decision will mostly be based on how old your home is and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional check your frames and window sills.

Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their service from a certain company, you won’t see it featured on EcoWatch.

This one is a give-and-take: similar to most services, cheap window installation companies won’t always provide the most quality service. Still, we want to make sure 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 serious investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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