How To Choose a Window Company in Riverhead

An exceptional reputation is essential when it comes to choosing a window provider. However, your chosen company should also align with your priorities and respect your vision. Consider the following factors during your company search:

Window Cost by Type

When it comes to window replacement, cost-effectiveness is most important. Each window you buy should offer top-notch durability at a reasonable price point. Choosing cheap windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The age of your home, in addition to the styles, sizes, and materials of replacement windows you choose, can affect pricing. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. If you're undecided, a window company can help you decide which options are most suitable for your home.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage Cost
Glass Block$49-$621

Window Material Cost

You'll also need to choose a window material. Homeowners usually choose a material based on the local climate, energy efficiency objectives and aesthetic preferences. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows up-front, but you'll need to invest in regular maintenance to prevent the frame from warping and wear. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window TypesAverage Cost

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to factor in the cost of installation, guarantees, and any other additional costs that your project may entail.

Experience and Training

Browse a company's website and chat with a representative to learn more about its product and service offerings, pricing, and warranties. Many window companies also keep online galleries that exhibit past projects.

Ensure that the company focuses on window replacement. The more dedicated instruction its staff has, and the longer it has been in business, the more likely it will provide high-quality workmanship.

Licensing and Credentials

New York's state government doesn't issue contracting licenses for window installers, but this doesn't stop local governments from intervening and creating their own licenses. For example, to place windows in New York City, a company must secure a Home Improvement Contractor License by passing exams and sustainability audits.

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's important to find a company that has expertise with the ones you want. Browse a company's website and reviews for any of these types:

Also, check the style of window framing materials a company works with. Each material has different price points, life spans, and energy performance capabilities. Common materials include fiberglass, vinyl, composite, wood and aluminum.

Customer Feedback

One of the best ways to vet a company is to read what other customers have written about their experiences. Trustworthy sources for customer reviews include Trustpilot, Yelp, and the BBB Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.
