How Installing Energy-Efficient Windows in Riverhead Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to think about making the switch:
- Better temperature control in your home: When you live in a city like Riverhead where the summers can be quite hot, you usually need to depend on your air conditioner to keep your house cool. Energy-efficient windows can cut back on how hard your AC needs to work to cool your home.
- 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.
- Better temperature control in your home: When you reside in a city like Riverhead where the winters can be very cold, you often have to depend on your heater to keep your home warm. Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Riverhead, that's about 307 pounds per year on average.
Estimated Cost of Window Replacement in Riverhead
Let's go over the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Typically, homeowners in Riverhead can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. How much it will cost you is based on several factors, including type, material, size, the location of your home, number of windows and more.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $215 a year on your energy bills in Riverhead.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations are simpler and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
Your window installation company will be able to help you understand what's best for your needs. In Riverhead, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Riverhead
In our search to find the most reliable, eco-friendly window installers in Riverhead, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
Because this is a guide for Riverhead, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Riverhead.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured on this list to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good things to say about their service from a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Riverhead's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Riverhead window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Can I install my own windows?
If you're handy and know how to replace a window, you may be able to install your own windows. However, if you don't have the time or skills, we don't recommend trying it.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, the weather should be dry, since rain can make the installation harder.
