If you're thinking about replacing doors in your Maine home, you're probably wondering what you're going to pay. I get it—door replacement isn't exactly cheap, and prices vary all over the place depending on what you're looking for. I've been in the home services industry for years, and I've noticed that folks in Portland, Lewiston, Bangor, and South Portland often ask the same questions about door costs.
The truth is, door prices in Maine depend on a bunch of factors. Are we talking about a basic interior door or a high-end exterior entrance? Is this a standard size, or do you need something custom? Are you dealing with a historic home that needs matching woodwork? These things matter, and they matter a lot when it comes to your final bill.
Let me break down what you're actually looking at in 2025, because I want you to go into this with your eyes open and your wallet prepared.
Interior doors are generally the most affordable option. If you're just looking to replace a bedroom door or a closet door, you're looking at pretty reasonable pricing. A standard hollow-core interior door runs between $75 and $200 for the door itself. If you want something nicer—maybe a solid wood door or something with some style to it—you're bumping that up to $200 to $400.
Now, here's where people get surprised: the installation. Labor costs for hanging a single interior door in Maine typically run $150 to $300. If you need the frame replaced or your door opening is in rough shape, tack on another $100 to $200.
So a basic interior door replacement in South Portland? You're probably looking at $300 to $600 total, maybe a bit more if there are complications. In smaller markets like some areas of Lewiston, you might find slightly lower labor rates, but honestly, the differences aren't huge.
Exterior doors are a different animal entirely. These aren't just about looks—they're protecting your home from Maine weather, which is no joke. Energy efficiency matters here, and that's going to hit your wallet.
A basic exterior door (like a standard entry door) runs $300 to $800 for the door unit itself. But here's the thing: most people don't want a "basic" exterior door. You want something that keeps the cold out during our brutal winters. Quality options with good insulation ratings run $800 to $1,500. Premium doors—think fiberglass, steel with insulated cores, or solid wood with proper weatherproofing—can easily hit $1,500 to $2,500.
Installation for an exterior door is more involved than interior work. You're looking at $300 to $500 in labor, sometimes more if your current door frame needs replacing or if there's water damage (which happens in Maine more often than we'd like). If the frame needs work, budget another $200 to $400.
A quality exterior door replacement in Portland or Bangor will run you $1,200 to $2,500 total. If you're doing multiple doors or need custom sizing, you could be looking at $3,000 or more.
Storm doors are popular here in Maine because, well, we need them. A decent storm door costs $200 to $500, with installation running another $100 to $200. They're a smart investment if you want extra protection against our weather without completely replacing your main door.
French doors? Patio doors? Sliding glass doors? These specialty options are pricier. You're typically looking at $600 to $2,000 for the unit, plus $300 to $500 for installation. In places like South Portland where people are doing more modern renovations, these are becoming popular, but they're definitely a premium choice.
If you need a custom door—maybe you've got a historic home and need matching woodwork, or your opening is an unusual size—prepare to spend $2,000 to $5,000 or more. These projects take time, and that's reflected in the price.
Several things will change what you actually pay. First, the condition of your existing frame. If you've got rot, water damage, or structural issues, installation gets complicated and expensive. Second, your choice of materials. Wood costs more than hollow-core, and fiberglass costs more than wood. Third, your location—rural areas around Lewiston sometimes have higher labor costs because contractors have further to travel, but urban areas like Portland and Bangor might have slightly more competition keeping prices down.
Seasonal timing matters too. Winter isn't the best time to replace exterior doors in Maine, and contractors know it. You might find better pricing in off-season.
How long does door installation take?
A single interior door usually takes 1-2 hours. An exterior door with frame replacement can take 4-6 hours or a full day depending on what's going on behind the scenes.
Should I replace the frame too?
If your current frame is solid and not damaged, you can often keep it. But if there's any rot, damage, or if the frame isn't square, replacing it is worth the extra cost. A damaged frame will cause problems down the road.
What's the best time to replace doors in Maine?
Spring through early fall is ideal. You want dry conditions for installation and to avoid emergency situations during winter when contractors are slammed.
