So you're looking to replace some doors in your Montana home, and you want to know what you're actually going to pay. Fair question. Door prices can vary wildly depending on what you're getting, where you live in the state, and who's installing them. I've put together this guide to give you real numbers based on what homeowners are actually spending across Montana right now.
Whether you're in Billings dealing with those brutal winters, Missoula where people care about aesthetics, Great Falls with its unpredictable weather, or Bozeman where everything costs a bit more, your door costs will shift based on local labor rates and material availability.
Let's start with what most people care about: your front door. This is the door people see first, and it needs to handle Montana's temperature swings.
A standard entry door in Montana runs you between $800 and $2,500 installed. That breaks down roughly like this:
In Billings, where contractors are competitive and there's solid labor availability, you might save a few hundred bucks on the installation side. Missoula and Bozeman tend to run about 10-15% higher because there's more demand and fewer contractors willing to work in winter months.
Pro tip: If your door frame is in bad shape, add another $200-$400 to replace it. Montana weather does a number on frames, especially on the north side of homes.
Interior doors are significantly cheaper, but people often underestimate how many they need to budget for.
A single interior door installation costs between $150 and $500 installed. Here's what that looks like:
If you're replacing doors throughout a home in Great Falls or anywhere else in Montana, interior doors add up. A typical house might have 8-12 interior doors. You're potentially looking at $1,200-$4,200 just for interior doors if you're doing a whole-home refresh.
Patio doors are another common upgrade, especially in Bozeman and Missoula where people want nice views of the outdoors.
Expect to pay $1,500 to $4,500 installed for a standard sliding glass patio door:
Montana winters mean you really want good insulation on these, so don't cheap out. The difference between a $1,200 and $2,200 patio door is usually better insulation, which saves you money on heating.
Garage doors are their own beast, and they're often overlooked until something breaks.
A new garage door in Montana costs $800 to $3,500 installed:
In all four major Montana cities, garage door prices are pretty consistent because they're standardized products. What changes is the opener cost and installation complexity.
Beyond the basic door type, several things will change your final bill:
Weather sealing: Montana homes need proper weatherstripping and sealing. That's an extra $100-$300 per door entrance.
Insulation value: Fiberglass and insulated steel doors cost more but pay for themselves in heating bills over 5-10 years.
Installation difficulty: If your door frame needs work or the opening isn't square, installation costs jump. Great Falls and Billings contractors typically charge $400-$600 for problem installations.
Hardware: Locks, handles, and hinges can add $50-$300 depending on quality.
A well-installed, quality door should last 20-30 years. Cheaper doors might need replacement in 10-15 years, especially if exposed to direct sun or harsh weather.
Not always, but if it's rotted, warped, or damaged, you should. Frames run $200-$400 to replace. It's worth doing it right the first time rather than dealing with air leaks later.
Steel and fiberglass with insulation cores are better. They don't warp like wood and have better thermal properties. Vinyl is fine for interior doors but upgrade to steel or fiberglass for exterior doors.
