How To Choose a Window Company in Decatur

Reliability is essential when it comes to choosing a window installer. However, your chosen company should also suit your priorities and respect your vision. Consider the following factors during your company search:

Window Cost by Type

When you're shopping for new windows, it's essential to remember that there's more to cost than just purchase price. You want a window with top-notch quality and durability. Choosing economy windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The style, size, and material of your new windows are the most significant factors in your final cost. 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. It's advisable to speak with a reliable installer to figure out your most suitable options.

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-$532

Window Material Cost

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

Other Window Replacement Costs

Your contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to factor in the cost of labor, guarantees, and any other supplemental fees that your project may entail.

Experience and Training

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

  • How long it's been in business
  • Photo galleries of completed projects
  • Privately-issued accreditations attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

Alabama requires window installation businesses earning more than $50,000 on residential work to have a license. The state's Licensing Board for General Contractors establishes guidelines and oversees exams.

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's vital to find a company that specializes in the ones you want. Look on a company's website and reviews for any of these types:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Also, check the kind of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include fiberglass, wood, composite, aluminum and vinyl.

Customer Feedback

Reading other customers' stories is an excellent way to screen different window companies. You can find customer reviews on websites like the BBB, Yelp, Google, and Trustpilot. Talk to 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 Decatur

What are the benefits of hiring a window installer?

By working with an expert, you don't need to worry about measurement missteps or lacking the right tools. A window installation crew is well-equipped with the right supplies and knowledge to do the job safely and precisely. You can also get fast, informed answers to your questions and personalized 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. You likely won't have to replace the entire window. Instead, a simple framing job could do. It's recommended to consult a window professional to ensure adequate sealing and weatherproofing.

My window screen tore. How should I fix it?

It depends on the size of the tear and its location on your window. You can usually address small tears yourself using a special kit. Some window providers will supply you with one when they install your windows, or you can buy one for $5–10 from a home improvement store. Bigger tears, or those located at the edge of a window, usually need professional repair.
