How To Choose a Window Company in Stamford

With Stamford's sheer size, you're sure to find a trustworthy window replacement company that aligns with your values and preferences. As you contact companies, keep the following factors in mind:

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 high-quality and durable window. Although top-of-the-line windows may come with a higher initial price tag, they often yield better long-term value due to their increased lifespan. The age of your home, together with the sizes, materials, and styles of windows you opt for, can impact pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. If you're undecided, a window specialist 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
Arched$239-$1,464
Awning$345-$962
Bay$796-$5,901
Custom$354-$983
Casement$275-$1,595
Double-hung$129-$830
Egress$236-$589
Glass Block$47-$597
Picture$207-$1,530
Single-hung$94-$1,574
Skylight$118-$1,421
Sliding$271-$1,377
Storm$56-$389
Transom$288-$603

Window Material Cost

Materials also help determine a window's cost. You might pick a material based on your desired look, the local climate, and your energy efficiency goals. For example, windows made of wood can give your home an organic design without breaking the bank, but you'll have to invest more toward maintenance. Aluminum and composite windows cost more up-front, but they're incredibly durable against the elements, so you'll spend far less on maintenance.

Window TypesAverage Cost
Aluminum$56-$1,574
Composite$568-$1,276
Fiberglass$94-$796
Vinyl$191-$1,770
Wood$284-$1,595

Other Window Replacement Costs

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

Experience and Training

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

  • How long it's been serving the Stamford area
  • Photo galleries of completed projects
  • Private accreditations 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 restrictions on what jobs they can perform. Most residential window installers are considered "minor contractors" and can only work on single and multi-family dwellings. 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 specializes in the ones you want. Look on a company's website and reviews for any of these types:

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

Customer Feedback

Perhaps the best way to evaluate window companies for your job is to see what previous customers have said about them. Read customer reviews on sites such as Yelp, Trustpilot, and Google. 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.
