How To Choose a Window Company in Bristol

Dependability is essential when it comes to choosing a window installer. However, your chosen company should also match your needs and appreciate your vision. Keep in mind the following factors during your company search:

Window Cost by Type

When you're shopping for new windows, it's crucial to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Although high-quality windows may come with a higher initial price tag, they often provide better long-term value due to their extended lifespan. The overall cost of your window replacement will depend on the particular materials, styles, and sizes you need. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. An expert can help you with choosing the options that fit your requirements.

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

Window TypesAverage Cost
Glass Block$47-$600

Window Material Cost

Window prices also vary based on material. Each option offers different benefits depending on your climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, so they tend to cost more.

Window TypesAverage Cost

Other Window Replacement Costs

Your total cost for window replacement will also include warranty fees (if applicable), permit-related costs (if required), and labor. Be sure to discuss each of these aspects with a sales representative before committing to a window company.

Experience and Training

The longer a window provider has been operating, the better its workmanship will likely be. Call a company representative to learn more about its guarantees, public and private credentials, and experience. Company websites often keep photo galleries where you can see previous work technicians have done.

Licensing and Credentials

While Connecticut doesn't require contractors to carry licenses, they must still register with the state's Department of Consumer Protection (DCP), and there are still restrictions on what jobs they can perform. Most residential window installers are considered "minor contractors" and can only work on single and multi-family houses. If a company performs glasswork, it must have a Glazier license from the DCP.

Types of Windows Offered

No two businesses offer the same window designs and materials. Find one that focuses on the type you want for your home.

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Equally important to your desired windows' shape is their framing. Ask your window provider if it offers the frame material you want, such as composite, aluminum, fiberglass, vinyl, or wood.

Customer Feedback

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

Frequently Asked Questions About Window Replacement in Bristol

What are the benefits of hiring a window installer?

By hiring an expert, you don't need to worry about making measurement mistakes or lacking the right tools. A window installation crew is well-equipped with the right tools and knowledge to do the job safely and precisely. You can also get fast, informed answers to your questions and personalized assistance to make the most of your new windows

Are there tax incentives for installing energy-efficient windows?

Yes. No matter where you're located, you can claim a federal tax credit of up to $3,200 per year on up to 30% of your window replacement's cost. Additionally, most state and some local governments offer tax breaks of their own. We recommend checking with your local government for specific information about tax incentives available in your area.

Do window companies have guarantees or warranties for their work?

We strongly recommend choosing a window company that backs their work with a guarantee for your protection. These plans usually cover material flaws, manufacturer defects, and workmanship errors for a short time after installation. Check the warranty details with a window company before hiring it.
