How To Choose a Window Company in Trumbull

An exceptional reputation is important when it comes to choosing a window provider. However, your chosen company should also match your priorities and appreciate your vision. Think about the following factors during your company search:

Window Cost by Type

When you're shopping for replacement windows, it's essential to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing economy windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The final cost of your replacement windows will hinge on the specific sizes, styles, and materials you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. If you're undecided, a window specialist can help you determine which options are ideal for your home.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage Cost
Glass Block$47-$596

Window Material Cost

Materials also help determine a window's cost. You might pick a material based on your desired look, your energy efficiency goals, and the local climate. For example, wooden 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

Other Window Replacement Costs

Your total cost for new windows will also include applicable warranty fees, 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

Browse a company's website and chat with a representative to learn more about its product and service offerings, pricing, and guarantees. Many window companies also keep online galleries that present past projects.

Ensure that the company focuses on window replacement. The more specialized training its staff has, and the longer it has been in operation, the more likely it will deliver excellent service.

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 residences. If a company performs glasswork, it must have a Glazier license from the DCP.

Types of Windows Offered

The type of window you desire should factor into your company choice. Not every installer will necessarily be familiar with the types you want. A company website will provide more about the window types it deals with, such as:

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, aluminum, fiberglass and composite.

Customer Feedback

Reading other customers' stories is one of the best ways to screen window companies in your area. Trustworthy sources for customer reviews include Yelp, Google, and Trustpilot Speak with people you know who have used the company you're interested in, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Trumbull

What are the benefits of hiring a window installer?

Replacing your windows is a big investment that greatly impacts your home's livability and energy efficiency. Hiring a reputable window contractor to manage your project ensures your windows will be the right size, operate effectively, and be properly insulated. Companies also typically include a guarantee that covers required maintenance and most future repairs.

What time of year should I replace my windows?

Window replacement can be carried out year-round. However, the installation process may be different depending on the season. Costs are often cheaper in winter when demand is off-peak. Keep in mind, however, that this could overexpose your home to the elements. Talk to a licensed window professional to determine the best climate conditions for your replacement project.

Do window installers also work with blinds and coverings?

Whether a company installs blinds ultimately depends on your state's licensing requirements and their own preferences. Many jurisdictions require window covering installers to get a unique license, and not every installer 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.
