How To Choose a Window Company in Windsor

Each window company has unique offerings and approaches. To ease the company search, keep these factors in mind:

Window Cost by Type

Replacing your windows is a major investment, so balancing cost with long life is vital. Although high-quality windows may come with a higher initial price tag, they often provide better long-term value due to their longer lifespan. The size, material, and style 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. If you're unsure, a window specialist can help you decide which options are best for your home.

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$43-$553

Window Material Cost

Window prices also vary based on material. Each option offers unique advantages depending on your climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, aluminum and composites look sleek and stay strong against the elements, so they tend to cost more.

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. Make sure to discuss each of these factors with a sales representative before committing to a window company.

Experience and Training

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

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

Licensing and Credentials

Colorado's contractor licensing requirements are distinct among states. There is no single regulatory body that licenses window companies, but they might still need licenses from local authorities in which they operate. Both Denver and Colorado Springs license window installers, treating them as either general contractors or building contractors. For other areas, check with your local government.

Types of Windows Offered

The type of window you want should factor into your company choice. Not every installation crew will necessarily be familiar with the window brand you want. A company website will tell more about the varieties of windows it works with, such as:

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

Customer Feedback

Reading other customers' stories is a great way to screen window companies in your area. Read customer reviews on sites such as Trustpilot, Google, and Yelp. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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 Windsor

Why should I hire a professional to install or replace my windows?

By working with a professional, you don't need to worry about making measurement mistakes or lacking the right tools. A window installation crew is well-equipped with the right tools and training to do the job safely and accurately. You can also get fast, informed answers to your questions and tailored help to make the most of your new windows

I've heard there are tax credits for energy-efficient windows. How much could I save?

Ultimately, the tax incentives you can claim depend on the scope of your window replacement and where you are. You can claim 30% of the value of new efficient windows as a federal tax credit, up to $3,200 per year, until 2032. We also encourage you to get in touch with your city or county government for more information on credits and incentives specific to your area.

My window screen tore. How should I fix it?

It depends on the tear size and where it's located on your window. You can usually repair small tears yourself using a special kit. Some window companies will supply you with one when they replace your windows, or you can purchase one for $5–10 from a local hardware store. Larger tears, or those located at the edge of a window, usually need professional assistance.
