How To Choose a Window Company in Missoula

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

Window Cost by Type

When you're shopping for new windows, it's crucial to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing cheap windows could actually raise your overall cost, due to their shorter lifespan and more intensive maintenance needs. The age of your home, together with the styles, sizes, and materials of windows you opt for, can impact pricing. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. It's advisable to speak with a reliable window installer to figure out your ideal options.

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

Window TypesAverage Cost
Arched$211-$1297
Awning$305-$852
Bay$704-$5228
Custom$313-$871
Casement$243-$1413
Double-hung$113-$735
Egress$209-$522
Glass Block$41-$529
Picture$183-$1355
Single-hung$82-$1394
Skylight$104-$1258
Sliding$240-$1219
Storm$49-$344
Transom$255-$534

Window Material Cost

Materials also help determine a window's cost. You might choose 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$49-$1394
Composite$503-$1130
Fiberglass$82-$704
Vinyl$169-$1568
Wood$251-$1413

Other Window Replacement Costs

Your total cost for window replacement will also include applicable warranty fees, permit-related costs (if required), and labor. Be sure to discuss each of these aspects with an estimator before committing to a window company.

Experience and Training

Select a company that focuses on window replacement and installation, and look for this information on its website:

  • The number of years it's been in business
  • Photo galleries of completed projects
  • Official non-government credentials attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

Montana requires window professionals to enroll in the Construction Contractor Registration Program instead of getting licensure. 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 explore private certifications from each company you're considering.

Types of Windows Offered

There are many replacement window types you can choose from, and it's vital to find a company that is experienced with the ones you want. Browse a company's website and reviews for any of these types:

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

Customer Feedback

Reading other customers' stories is an excellent way to screen window companies in your area. Trustworthy sources for customer reviews include Google, Yelp, and Trustpilot 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.

Frequently Asked Questions About Window Replacement in Missoula

How could new windows help my energy efficiency?

In Missoula specifically, most homeowners using efficient windows reduce their carbon emissions by 320 pounds annually. This means they save $430 on their annual electricity costs.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By upgrading to new, more efficient windows, you can boost your home's energy efficiency and minimize your electricity bills.

Do I need a building permit to replace my home's windows?

Whether you need a building permit to replace your windows varies on your local building codes and regulations. Some towns require permits for window replacement projects, especially those involving structural changes or alterations to the window openings. We recommend you check with your local building department or contact a professional before beginning any window replacement work.

My window screen tore. How should I fix it?

Most broken screens are very simple to fix. For small tears, some window service providers might give you a repair kit that use strong adhesive patches. If your installer doesn't include a kit, you can buy one for about $5–$10 at a home improvement store.

You might need to get a new screen for large tears or those along the edges of the window. A window installer you trust can get the job done at a reasonable cost.
