Tips to Help You Choose the Best Window Installation Contractor in Nassau County

Windows are one of the most important elements of your Bayville, NY home. Not only do they filter natural light into your house and let you take in the outdoor views, but windows are a source of much-needed fresh air and play an important role in the efficiency of your home. Add to all of these things the fact that windows have a big impact on the curb appeal of your Nassau County property, and it’s easy to see why they’re so important. 

Since windows are such a vital part of your house, it’s safe to say that if you’re planning on installing new ones, you want to make sure that they are expertly installed. When you’re looking for a window replacement contractor, you’re going to find a lot of different companies to choose from. How can you narrow down the options and ensure that the window installation contractor you choose is the very best? When you’re comparing window contractors, consider the following key criteria and you’ll be able to find a company that you can rely on to install beautiful, efficient, and functional windows that you’ll be able to enjoy for years to come.


Cost is one of the most important factors Bayville, NY homeowners take into consideration when they’re looking for a window installation contractor, and that’s totally understandable. Replacement windows can be costly, so you want to be sure that you choose a contractor who charges rates that are within your budget. With that said, however, while it may be tempting to choose a window contractor that charges the lowest price, if a quote seems too good to be true, it probably is. Do you know the old saying “you get what you pay for”? Well, it certainly applies to replacement windows. If a contractor charges super-low rates, it’s likely that they’ll do subpar work, they use poor-quality windows or both. When it comes to your windows, you shouldn’t settle for anything less than the best.

Windows have a huge impact on the efficiency of your Bayville, NY home and if they’re inefficient, your utility bills will go up. While the window installation contractor may have charged a really low rate, in the end, you could actually end up paying the same – if not more – than you would have for a contractor who expertly installs premium-quality windows. Paying more to have your windows installed may actually end up paying off in the long run.

Materials and Glass

It goes without saying, but you want to be sure that the window installation contractor you choose offers high-quality windows made of durable materials. Ask prospective contractors what type of windows they use, including the casing materials, the glass, and the manufacturers.

Vinyl, fiberglass, and wood are the three most common materials used for window casings, but keep in mind that not all manufacturers use these materials in the same way. For example, some manufacturers that offer wood casings only offer hollow, not solid, and of course, if solid wood is what you’re looking for, you’ll want to be sure that the contractor you choose offers that option. 

In regard to glass, there are so many different kinds available, including safety laminated, insulated, tinted, float, tempered, and even low-emissivity (low-E). The type of glass that will work best for you really depends on your specific needs. Speak with each window installation contractor you meet with to find out the different types of glass they offer and if they carry an option that will best meet your needs.

Window Style

When you’re choosing a window contractor, you also want to be sure that they offer styles that will suit your taste. Windows come in an assortment of styles. Some of the different options include single sash, sliding single slash, double-hung, casement, bay, bow, awning, and fixed. The style you choose, of course, depends on your specific preference, the design of your Bayville, NY house, and how you want to use the window.

With that said, make sure to ask about the different styles each window contractor you meet with offers and take a look at their inventory. Obviously, if a window installer doesn’t offer the specific style you’re looking for, then you’ll want to look for a contractor who does.


Your windows are only as good as the company that installs them. It doesn’t matter if you select the highest-end windows from the best manufacturer, if a contractor doesn’t properly install them, you’re going to end up having problems. For that reason, it’s important to find out what type of credentials each window replacement contractor offers, as credentials are a direct reflection of the quality of craftsmanship you can expect. Are they licensed and certified? Are they affiliated with any professional organizations? Are their employees professionally trained? How many years have they been in business?

You want to choose a window contractor that has ample knowledge and experience, so make sure you check credentials before hiring. You’ll want to find out if they’re fully insured, too.
