How Installing Energy-Efficient Windows in Uniondale Saves You Money

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

  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
  • Save on energy bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save about $283 annually on your energy bills in Uniondale.
  • Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 307 pounds per year on average.
  • Protect your investment: If you have an older home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Uniondale

Each window replacement company provides varying services and has different prices based on several factors.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will add extra costs to your project.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Uniondale homeowners $283+ per year after replacing single-pane windows.

Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with 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 provide decent insulation for your home.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail replacing a 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 unsure which kind of window installation service you need, your installer should be able to help you out. In general, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Uniondale

EcoWatch differs from other reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Uniondale and assigned rankings using the following methodology:

Service Area

Because this is a guide for Uniondale, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Uniondale.

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers higher marks 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, 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 professionalism, quality of parts, quality of installation, cost, warranty and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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

Uniondale, NY Window Replacement FAQs

How much should window installation cost?

The national average cost to replace one window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is generally influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What are the different kinds of windows?

The most common types of windows for homes are slider windows, bay windows, transom windows, awning windows, casement windows, double-hung and single-hung windows and picture windows.

Do I really need to use a window installation company?

Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complex and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.

When is the best time of year to replace windows?

Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on energy costs, replacing all of the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
