How Installing Energy-Efficient Windows in Altamont Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to consider making the switch:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: In Altamont, you can lower your indirect greenhouse gas emissions by about 271 pounds per year after you switch to energy-efficient windows.
- Save money on power bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in Altamont
Windows come in varying styles, purposes and shapes, so costs and services will vary remarkably depending on your project. Below, we go over the typical cost and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200. How much it will cost varies depending on several factors, like number of windows, type, material, size, the location of your home and more.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — especially during the winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Altamont homeowners $523+ a year after replacing single-pane windows.
Costs will also vary based on the material you pick for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the full window, including the trim, frame and sill. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Altamont, the decision will mostly be influenced by how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Altamont
In our hunt to make your home improvements easier and more eco-friendly in Altamont, the EcoWatch Reviews team assessed many companies before deciding on these. We have evaluated the best window replacement companies in Altamont primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of parts, quality of installation, warranty, cost and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as 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, windows are a serious 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 labor rank higher with EcoWatch.
Years of Experience
Due to Altamont’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Altamont window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Altamont, OR Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost of installing a window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the types of windows?
The most common types of windows for homes are awning windows, casement windows, bay windows, picture windows, double-hung and single-hung windows, slider windows and transom windows.
When do I have to use a window installation company?
Unless you’re handy and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is generally better for replacing windows. In addition, the weather should be dry, as rain can make the installation harder.
