How To Choose a Window Company in Glastonbury

It's crucial to find a window installer that aligns with your specific values, needs, and preferences. Consider the following traits during your search:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with value is important. Although premium windows may cost more upfront, they often provide better long-term value due to their increased lifespan. The age of your home, as well as the sizes, materials, and styles of replacement windows you choose, can influence pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. It's recommended to speak with a trusted window installer to determine your most suitable options.

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
Arched$240-$1473
Awning$347-$967
Bay$800-$5937
Custom$356-$989
Casement$277-$1605
Double-hung$129-$835
Egress$237-$592
Glass Block$47-$600
Picture$208-$1539
Single-hung$94-$1583
Skylight$118-$1429
Sliding$272-$1385
Storm$56-$391
Transom$290-$606

Window Material Cost

You'll also need to pick a window material. Homeowners usually base their decision on aesthetic preferences, the local climate and energy efficiency objectives. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less 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 TypesAverage Cost
Aluminum$56-$1583
Composite$571-$1284
Fiberglass$94-$800
Vinyl$192-$1781
Wood$285-$1605

Other Window Replacement Costs

Ask each contractor you're evaluating about warranty fees, labor costs, and permit fees. This will help you get a better picture of the financial commitment involved in the project.

Experience and Training

Choose a provider that focuses on window repair and installation, and look for this information on its website:

  • How many years it's been operating
  • Photo galleries of projects its crews completed
  • Private credentials attesting to its workmanship
The more experience a company has, the better its service and workmanship.

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 limitations 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

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

Finally, pay close attention to the materials that a window company uses. Each window frame material has a different life span, price point and energy efficiency level. A company will usually specify whether the windows they place use vinyl, wood, composite, fiberglass, or metal.

Customer Feedback

One of the simplest ways to evaluate a company is to see what other customers have said about their experiences. Trustworthy sources for customer reviews include Google, the BBB, and Yelp 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 Glastonbury

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

Window replacement is an important purchase that greatly impacts your home's livability and energy efficiency. Hiring a skilled window installer to manage your project ensures your windows will fit correctly, operate effectively, and be properly insulated. Companies also typically include a guarantee that addresses required maintenance and most future repairs.

What should I do if a window is molding or has rot?

A molding or rotting window frame points to a moisture issue. You likely won't have to replace the entire window. Instead, a simple framing job could do. It's recommended to consult a window expert to ensure a proper seal.

Do window installers also work with blinds and coverings?

Whether a company can sell and install blinds ultimately depends on your state's licensing requirements and their own preferences. Many jurisdictions require window covering installers to get a separate license, and not every professional will carry one. If you'd like blinds with your new windows, inquire with a company representative if its crews can handle the measuring, cutting, and mounting. If a company can't install blinds, they could refer you to another company or subcontract the work.
