How To Choose a Window Company in Denver

With Denver's large population, you're sure to find a dependable window company that suits your values and preferences. As you make calls, keep the following factors in mind:

Window Cost by Type

When it comes to replacing your windows, cost-effectiveness is key. Each window you purchase should offer top-notch durability at a reasonable price point. Although top-of-the-line windows may be more expensive to buy, they often provide better long-term value due to their extended lifespan. The size, style, and material of your new windows are the most significant factors in 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. A professional can guide you through choosing the products that fit your preferences.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Glass Block$44-$565

Window Material Cost

Window prices also vary based on material. Each option provides 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 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 installation, guarantees, and any other supplemental fees that your project may require.

Experience and Training

The longer a window provider has been operating, the better its workmanship will likely be. Talk with a company representative to learn more about its public and private credentials, guarantees, and experience. Company websites often keep photo galleries demonstrating previous work technicians have done.

Licensing and Credentials

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

Types of Windows Offered

No two businesses offer the same window designs and materials. Look for one that's an expert in the type you want for your home.

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Finally, pay close attention to the materials that an installer uses. Each frame material has a different energy efficiency level, price point and life span. A company will usually specify whether the windows they place use wood, metal, fiberglass, composite, or vinyl.

Customer Feedback

One of the simplest ways to screen a company is to see what other customers have written about their experiences. You can find customer reviews on websites like Google, the BBB, Trustpilot, and Yelp. Talk to people you know who have used the company you'd like to hire, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Denver

What are the benefits of hiring a window installer?

By hiring a professional, you don't need to worry about making measurement mistakes or not having the right tools. A window installation team is well-equipped with the right supplies and skills to do the job safely and precisely. You can also get fast, informed answers to your questions and personalized help to maximize your new windows' potential.

Are there tax incentives for installing energy-efficient windows?

Ultimately, the tax incentives you can claim are determined by the scope of your window replacement and the community you live in. 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 speak with your city or county government for more information on credits and incentives specific to your area.

How important are guarantees and extended support packages?

Window companies often provide assurances for their work. Each typically addresses issues with workmanship and materials for a specified period of time. It's essential to verify the details of the guarantee with a window company before signing a contract.
