How To Choose a Window Company in Danbury

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

Window Cost by Type

When it comes to upgrading your windows, value is paramount. Each window you purchase should provide unparalleled durability at a fair price point. Although high-quality replacement windows may come with a higher initial price tag, they often yield better long-term value due to their extended lifespan. The size, material, and style of your replacement 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 new skylights cost more to prepare for and install. A window expert can guide you through picking the products that fit your needs.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Arched$238-$1464
Awning$345-$961
Bay$795-$5899
Custom$353-$983
Casement$275-$1595
Double-hung$128-$830
Egress$235-$589
Glass Block$47-$596
Picture$207-$1529
Single-hung$93-$1573
Skylight$117-$1420
Sliding$270-$1376
Storm$55-$388
Transom$288-$603

Window Material Cost

You'll also need to select a window material. Homeowners usually make their selection by considering the local climate, aesthetic preferences 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 TypesAverage Cost
Aluminum$55-$1573
Composite$568-$1276
Fiberglass$93-$795
Vinyl$191-$1769
Wood$284-$1595

Other Window Replacement Costs

Ask each contractor you're considering about labor costs, warranty fees, and permit fees. This will help you get a clear picture of the overall expenses involved in the project.

Experience and Training

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

  • How long it's been in business
  • Photo galleries of completed projects
  • Official non-government 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 categorized as "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 important to find a company that has expertise with the ones you want. Look on a company's website and reviews for any of these types:

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

Customer Feedback

Reading other customers' stories is a surefire way to screen potential window companies. Read customer reviews on sites such as Google, Yelp, and Trustpilot. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Speak with people you know who have used the professional you're thinking of hiring, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Danbury

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

By hiring a professional, you don't need to worry about making measurement mistakes or not having the right tools. A window installation team is well-equipped with the right supplies and training to do the job safely and accurately. You can also get fast, informed answers to your questions and tailored guidance to maximize your new windows' potential.

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

A molding or rotting window frame points to a moisture issue. Luckily, you may not have to replace the entire window. Instead, a simple framing job could do. It's best to consult a window professional to ensure correct sealing and weatherproofing.

How can I gauge the quality of a replacement window?

One of the first metrics you'll encounter when looking at a replacement window is its U-factor. The lower this number, the better the window is at preventing extreme cold and heat from entering your home. Other numbers to look at include:
  • "visible transmittance," which measures how much light enters through the window
  • "solar heat gain coefficient," which tells you how much UV light the window absorbs and releases as heat
  • "Condensation resistance," which determines how well a window can resist moisture (the higher the number, the better)
  • "Air leakage," which measures how easy it is for air drafts to develop (the lower the number, the better)
