How To Choose a Window Company in Helena

Dependability is important when it comes to choosing a window provider. However, your chosen company should also align with your needs and appreciate your vision. Keep in mind the following factors during your company search:

Window Cost by Type

Replacing your windows is a substantial expense, so balancing cost with quality is important. Choosing economy windows could actually raise your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The size, material, and style of your new windows play the largest role in determining your final cost. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. A professional can help you with selecting the products that fit your needs.

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

Window TypesAverage Cost
Arched$210-$1,288
Awning$304-$846
Bay$700-$5,192
Custom$312-$865
Casement$242-$1,404
Double-hung$113-$731
Egress$208-$518
Glass Block$42-$525
Picture$182-$1,346
Single-hung$82-$1,385
Skylight$104-$1,250
Sliding$238-$1,212
Storm$49-$342
Transom$254-$531

Window Material Cost

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

Window TypesAverage Cost
Aluminum$49-$1,385
Composite$500-$1,123
Fiberglass$82-$700
Vinyl$168-$1,558
Wood$250-$1,404

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 additional costs that your project may need.

Experience and Training

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

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

Licensing and Credentials

Montana requires window installers to enroll in the Construction Contractor Registration Program instead of obtaining licensure. The law applies to any business that removes from or adds to real property, be it a home or a business. Since there's no licensing exam involved, we advise you to look into private certifications from each company you're researching.

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. Check a company's website and reviews for any of these types:

Finally, pay close attention to the framing materials that a provider uses. Each window frame material has a different life span, price point and energy efficiency level. A company will usually specify whether the windows they set up use metal, fiberglass, wood, vinyl, or composite.

Customer Feedback

Reading other customers' stories is one of the smartest ways to screen different window replacement companies. Trustworthy sources for customer reviews include the BBB, Google, and Trustpilot Ask people you know who have used the company you're evaluating, and ask a representative for professional references.
