How To Choose a Window Company in Middletown

It's essential to find a window installer that aligns with your unique values, needs, and preferences. Consider the following areas during your hunt:

Window Cost by Type

Replacing your windows is a significant undertaking, so balancing cost with performance is important. Choosing economy windows could actually raise your overall cost, due to their reduced lifespan and more intensive maintenance needs. The age of your home, in addition to the styles, sizes, and materials of windows you select, can influence pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. A window expert can help you with choosing the options that fit your requirements.

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
Glass Block$42-$534

Window Material Cost

Materials also help determine a window's cost. You might choose 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

Ask each window installer you're considering about labor costs, warranty fees, and permit fees. This will help you understand the total costs involved in the project.

Experience and Training

The longer a window installer has been operating, the better its workmanship will likely be. Contact a company representative to learn more about its public and private credentials, experience, and guarantees. Company websites often keep photo galleries where you can see previous work technicians have done.

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 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 several replacement window types you can choose from, and it's essential to find a company that specializes in the ones you want. Browse a company's website and reviews for any of these types:

Equally important to your desired windows' shape is their framing. Ask your window provider if it offers the frame material you want, such as aluminum, composite, wood, vinyl, or fiberglass.

Customer Feedback

One of the best ways to screen a company is to check what other customers have said about their experiences. Read customer reviews on sites such as Yelp, Google, 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 a company you're interested in, and ask a representative for a copy of its reference list.

Frequently Asked Questions About Window Replacement in Middletown

What are the benefits of hiring a window installer?

Replacing your windows is an important investment that greatly impacts your home's livability and energy efficiency. Hiring a professional window company to manage your project ensures your windows will be properly installed, perform optimally, and be well-sealed. Companies also typically include a warranty that covers required maintenance and most future repairs.

Are there tax incentives for installing energy-efficient windows?

Yes. No matter where you're located, you can claim a federal tax credit of up to $3,200 per year on up to 30% of your window replacement's cost. Additionally, most state and some local authorities offer financial incentives of their own. We recommend consulting your local energy department for specific information about tax incentives available in your area.

Is it better to replace all my windows at once, or just a few at a time?

To form a window replacement strategy, consider your budget, home improvement goals, and energy efficiency targets. A step-by-step replacement helps you save money and focus on the windows that need the most attention, but you'll also notice smaller gains in efficiency. A complete window replacement will cost more up front, but you'll see a more noticeable energy efficiency improvement.
