Replacement windows can make your home quieter, less drafty, and more attractive. Though new windows are touted as ways to save money on your energy bills, this is misleading, as it could take years to recoup the investment. Still, new windows are easier to clean than old windows, can reduce your carbon footprint, and increase your home’s resale value.

Signs that you may need to replace your windows include high energy bills, drafts in your home, difficulty opening or closing windows, glass that’s cold to the touch on double-paned windows, or windows in such a state of disrepair that mending them is impossible. Know beforehand which windows need to be replaced, and consider a wide range of brands and window types. Sitting on an estimate can also help you negotiate a better deal.

Before settling on a company, consider all the options, and attempt to obtain at least five estimates from both local companies and franchised or corporate operations. Keep in mind that you’re not just shopping for the windows themselves, but also for the installation. Ask the company if they have liability insurance, worker’s compensation insurance, what their workmanship warranty is like, and whether the contractor is licensed by your state or city.

Important things to look out for in the final contract include the payment options and terms, a right-to-rescind clause establishing a time period in which you can cancel the contract with no penalties, scheduling, compliance with local codes and ordinances, manufacturer’s warranty specifications, daily cleanup, and a preliminary inspection with the job supervisor.

One intangible factor to look for when searching for a replacement window provider is the quality of the services it provide.

Assistance from a professional contractor for example can be a big help in making sound structural decisions. Excellent after services such as troubleshooting, claims and maintenance should also be high in your priorities.

Window Types


A company that provides a wide variety of window types and brands gives property owners more choices in terms of replacement windows. Some companies have an all-in-one –roof service that goes from designing to manufacturing replacement windows. This is a great option especially for homes with personalized window styles and are looking to upgrade or replace windows.

Energy Efficiency


Installing energy efficient replacement windows does not only help save you on your next energy bill but this also adds to the overall value of your home. Replacement windows with the energy star logo are guaranteed to be highly efficient in saving energy costs. Some of these also come with a noise reduction feature that can be invaluable especially in a busy neighborhood.

Like any other consumer, a major factor in deciding which replacement window provider to select depends on how much it’s going to cost you. Some of the factors that go into the price includes the materials used, window type and functionality (energy efficient, security window, noise proof) among others. While this could be different for each consumer there are factors such as professional consultation or installation fees to consider. Search for added value items such as warranty or free maintenance services to help you get a more accurate picture of not only how much the initial purchase is going to cost you but its overall costs over time.

Although broken glass is an item that is not frequently covered under warranties, some replacement window providers offer this but with limitations. Leaks and broken seals for example are commonly covered under warranties but be sure to discuss this with the company. A lifetime warranty is a clear indication of the company’s confidence in its product and the service it provides.
