How To Choose a Window Company in Brentwood

It's important to find a window company that meets your specific values, needs, and preferences. Consider the following points during your hunt:

Window Cost by Type

When it comes to replacing your windows, value is paramount. Each window you purchase should deliver unparalleled durability at an affordable price point. Although premium windows may come with a higher initial price tag, they often provide better long-term value due to their increased lifespan. The material, style, and size of your new windows are the most significant factors in your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. If you're unsure, a window specialist can help you determine which options are best for your home.

In this table, you can find cost data for the most common residential window types to determine how much you might pay.

Window Types Average Cost
Arched $248-$1525
Awning $359-$1001
Bay $828-$6147
Custom $368-$1024
Casement $286-$1661
Double-hung $133-$865
Egress $245-$613
Glass Block $49-$621
Picture $215-$1593
Single-hung $97-$1639
Skylight $122-$1479
Sliding $282-$1434
Storm $58-$405
Transom $300-$628

Window Material Cost

You'll also need to pick a window material. Homeowners often choose a material based on aesthetic preferences, the local climate and energy efficiency objectives. 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 wear and warping. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window Types Average Cost
Aluminum $58-$1639
Composite $591-$1329
Fiberglass $97-$828
Vinyl $199-$1844
Wood $295-$1661

Other Window Replacement Costs

Ask each contractor you're considering about warranty fees, labor costs, and permit fees. This will help you understand the financial commitment involved in the project.

Experience and Training

The longer a window installer has served your area, the better its workmanship will likely be. Contact a company representative to learn more about its guarantees, public and private credentials, and experience. Company websites often keep photo galleries demonstrating previous work technicians have done.

Licensing and Credentials

New York's state government doesn't issue contracting licenses for window installers, but this doesn't stop local governments from stepping in and setting up their own licenses. For example, to put in windows in New York City, a company must obtain a Home Improvement Contractor License by passing exams and environmental audits.

Types of Windows Offered

The kind of window you desire should influence your company choice. Not every contractor will necessarily be familiar with the types you want. A company website will tell more about the kinds of windows it focuses on, such as:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Also, check the type of window framing materials a company works with. Each material has varying price points, life spans, and energy performance capabilities. Common materials include fiberglass, aluminum, wood, composite and vinyl.

Customer Feedback

Perhaps the best way to prescreen window companies for your job is to find out what previous customers have said about them. You can find customer reviews on websites like the BBB, Yelp, Google, and Trustpilot. 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.

Frequently Asked Questions About Window Replacement in Brentwood

Why should I hire a professional to install or replace my windows?

Window replacement is a substantial purchase that greatly impacts your home's comfort and energy efficiency. Hiring a reputable window contractor to supervise your project ensures your windows will be properly installed, perform optimally, and be well-sealed. Companies also typically include a warranty that addresses required maintenance and most future repairs.

What is the maintenance schedule for an average window, and how long will it last?

Refer to your warranty information to best understand how long your windows are meant to last. Most residential windows have life spans of 15–20 years. Check your windows for damage, leaking, and poor performance to determine whether you need a replacement.

How long does a window replacement job take?

The length of a window replacement project depends on several factors. It usually takes up to a month for the contractor to receive your windows from the manufacturer. The installation process itself often takes around an hour per window. However, larger windows or more complex installations may require additional time.
