That varies tremendously depending on where you are located and the difficulty of the job. You've given no details, so no one can give you a number that will be helpful or reliable. It's like asking, "How much to remodel my bathroom?"

It's probably safe to say the door swap is in the range of $500-$5000, but I doubt that that is very helpful to you. My suggestion is to get at least three contractors to bid, and that will give you the best idea for your locale and situation.

I'm not sure why you'd buy a replacement door and then look for an installer as opposed to having a contractor price changing the door for you and let him get his own materials. I don't think you'll save any money by buying the door yourself.

Anyway, as kudzu said, someone needs to take a look at your particular situation to give you a realistic estimate.

If it helps, I had my cheap hollow luan doors replaced with solid pine 6-panel doors. It was time and materials. 6-doors ended up costing me ~$300/door. He bought blank doors and had to fit/install hinges and hardware to hang in the existing frames.

The details are that my architect ordered the wrong door. She moved and is no longer part of the project. Now, I have a french door where I want a solid slab door. My contractor told me it would cost an additional $600 to switch doors. I thought a typical french door that is the same size, brand and from the same company would be more expensive than a slab door. I was confused as to why it would be an additional $600. I was hoping to get some insight as to how much it would typically cost to switch out a door. I have no experience in this subject and was hoping people here might be able to help. I don't know what the name of the door or company or any other information about it or I'd have posted it.

It's not clear what's going on. Are you saying that the French door is already installed, or it's in the plans for your new build but isn't actually installed yet? Or is the $600 the labor charge for swapping out an already installed door?

There is a brand new, fully functioning french door in my home. If I were to get all my money back for the french door, and if I already own a slab door that is the perfect size and from the same manufacturer, how much should I expect to be charged for the removal of the french door and the hanging of the slab door?

so the contractor's price is $600 to change out the the door and he leaves you the french door. If you're implying that the contractor should change the door for free (or give you a credit for swapping doors) because the slab door is likely less expensive than the french door...it doesn't work that way.

I don't know what the trim detail is around the door but it sounds like removal of the french door and installation of the slab door might well be a $600 job. Does the price include all trim/paint/hardware installation, so you've got a brand new, fully functioning slab door when the job is through? Even more reason why $600 might be reasonable.

Of course you get to keep the new french door and can do with it what you please.

HTH and good luck.

Be aware that there is no such thing as easily swapping out one door for another and expecting the replacement to fit properly just because it's from the same manufacturer and the same size. Every door installation requires adjustments due to small but significant differences in hinge placement and actual (vs. nominal) size. In fact it's often easier to install a door from scratch than it is to remove an existing door, adjust or tear out and replace the existing jamb, and do the new installation. Depending on the specific situation, $600 might be a bargain.

Thank you Joseph Corlett and others. I appreciate your straight to the point response.

rob-

I understand where you are coming from. If you haven't installed doors yourself it's entirely logical to assume it should be easy and cheap to swap two "identically-sized" doors. I hope you are now comfortable that your contractor is not trying to take advantage of you. Good luck with your project.

It's not driving several screws and tacking on trim. Proper caulking makes it not so easy to carefully remove your French door when you're hoping to sell it as almost new. And the opening has to be cleaned so the new door can be correctly sealed. I'd check with the yard that supplies your door for people they know who install these doors. That could save you a bit and alert a number of guys to the fact of your available French door for one of their future jobs. Those are popular so it should go at a fair but discounted price.
