How To Choose a Window Company in Stamford

With Stamford's large population, you're sure to find a reputable replacement window company that suits your values and preferences. As you reach out to companies, keep the following factors in mind:

Window Cost by Type

Replacing your windows is a major investment, so balancing cost with performance is vital. Choosing budget windows could actually raise your overall cost, since they come with a reduced lifespan and more intensive maintenance needs. The material, style, and size of your replacement windows have the greatest impact on 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 provider can help you determine which options are best for your home.

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

Materials also help determine a window's cost. You might select a material based on your energy efficiency goals, your desired look, and the local climate. For example, wood windows 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$55-$1573
Composite$568-$1276
Fiberglass$93-$795
Vinyl$191-$1769
Wood$284-$1595

Other Window Replacement Costs

Ask each contractor you're evaluating 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

Browse a company's website and contact a representative to learn more about its product and service offerings, pricing, and warranties. Many window companies also keep online photo galleries that highlight past projects.

Ensure that the company focuses on window replacement. The more specific training its staff has, and the longer it has been in operation, the more likely it will provide excellent 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 residences. If a company performs glasswork, it must have a Glazier license from the DCP.

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's essential to find a company that is experienced with the ones you want. Search 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 different price points, life spans, and energy performance capabilities. Common materials include composite, vinyl, fiberglass, wood and aluminum.

Customer Feedback

Reading other customers' stories is one of the best ways to screen different window companies. Trustworthy sources for customer reviews include the BBB, Yelp, and Google 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 Stamford

How could new windows help my energy efficiency?

In Stamford specifically, most homeowners using efficient windows lower their carbon emissions by 150 pounds each year. That amounts to $440 of annual savings.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By investing in new, more efficient windows, you can enhance your home's energy efficiency and minimize your electricity bills.

How frequently should I upgrade or replace my windows?

Windows don't last forever, and most vinyl models are constructed to serve your home for around two decades. Over time, weatherproofing materials weaken, framing shifts, and window coatings deteriorate. These changes result in condensation, air leaks, energy loss, and other expensive problems necessitating repair or replacement.

How do replacement windows differ from new construction windows?

New construction windows are specifically designed for fresh builds and significant renovation projects. Most, but not all, have a vinyl "nailing fin" that extends from the frame and secures the window to the house's sheathing. On the other hand, replacement windows (sometimes called "retrofit windows") don't have their own nailing fin. Instead, they're crafted to use the existing sheaths.
