Rugs, Carpets and Carpeting - New carpet, now doors are dragging...

I just had some carpet installed today which I purchased at Home Depot. I got the 1/2 inch pad thinking that it would make the carpet feel nicer. However, it turns out that while I'm very happy with the way the carpet turned turned out, I can no longer open my interior doors freely. It's not impossible to open or anything, but I'm trying to sell my house, and dragging doors was not the impression I was trying to make by installing new carpet. :(

I really wish Home Depot would have warned me before I got the thick pad. I'm not a DIY'er (as I'm sure you've noticed), and the thought that the doors might drag was something that didn't occur to me.

So, now what should I do? Will the carpet get compressed over time so that I don't really need to do anything? I've done a little bit of research, and saw someone suggest using a jack plane to trim the doors down a little bit. There are 6 doors affected by the new carpet. For a non-DIY'er like myself, should I even attempt such a project? If not, how much should I expect to pay to get it done for me?

You can use a belt sander and a coarse belt if a saw spooks you.

Its a very easy job if you have the right tools and a place to set up.
As Daniel said, a belt sander is perfect. I'd rather use that than a plane.
I use my cordless circular saw if I need to take off 1/4 inch or so. Put on masking tape before you use the saw so it keeps the door from splintering.
PS: Before you take the door off, put a chunk of tape at the bottom so you remember which end to trim (I know I'm not alone on this mistake)
My experience has been that the carpet will not compact.

Thanks, I'll try that. My friend has a belt sander, and is more diy inclined than I am, so I'll see if he can help me.
Thanks for the advice!

With the belt sander, draw a line on the door showing how much to take off. Without the line, you won't know how much you have removed plus it helps the keep the sanding line uniform.

If your friend is handy I would go the skill saw route. If your dragging that badley it sounds like you may need about a 1/4 off the bottom - a lot to belt sand.

I would use a clean piece of lumber like a 1*2 of even a level with a pair of clamps on the door. you would put this on the door as a guide for the saw to get a perfect cut. ( meaasure the distance from the blade to the outside edge of the saw + the amount you want to cut off, transfer this to the door and setup your straight edge this distance from the bottom. You can also start with an 1/8 off and if that don't cut it, take another 1/8 off) Again use painters tape were the cut will be and you'll have a nice clean edge.

Measure the door up where you want it cut.

Lay a yard stick on your marks and use a razor knife to scribe and cut the top veneer on the door. This will keep it from splintering.

Then take some blue painters tape and lay the edge of the tape, right on the line you cut.

Now using the circular saw, cut the door off on your line.

You can then sand any rough cut.
