How To Choose a Window Company in Kalispell

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

Window Cost by Type

Replacing your windows is a significant investment, so balancing cost with long life is vital. Although premium windows may cost more upfront, they often yield better long-term value due to their longer lifespan. The material, size, and style of your replacement 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 undecided, a window company can help you figure out which options are best for your home.

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

Window TypesAverage Cost
Arched$216-$1,322
Awning$312-$868
Bay$718-$5,329
Custom$320-$888
Casement$249-$1,441
Double-hung$116-$750
Egress$213-$532
Glass Block$43-$539
Picture$187-$1,382
Single-hung$84-$1,421
Skylight$107-$1,283
Sliding$245-$1,243
Storm$51-$351
Transom$261-$545

Window Material Cost

Materials also help determine a window's cost. You might pick a material based on your energy efficiency goals, your desired look, and the local climate. For example, windows made of wood 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
Aluminum$51-$1,421
Composite$513-$1,153
Fiberglass$84-$718
Vinyl$173-$1,599
Wood$257-$1,441

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 extra expenses that your project may need.

Experience and Training

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

Licensing and Credentials

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

Types of Windows Offered

No two window contractors offer the same window types and materials. Find one that focuses on the type you want for your home.

Also, check the style of window framing materials a company works with. Each material has different price points, life spans, and energy performance capabilities. Common materials include wood, vinyl, fiberglass, aluminum and composite.

Customer Feedback

Perhaps the best way to prescreen window companies for your job is to find out what previous customers have said about them. Trustworthy sources for customer reviews include Google, the BBB, and Yelp 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.
