Can I do this myself?

Yes.  Anyone can do this for his or herself.  It's going to take some guts, some tools, and a lot of time, but you can do it.  We always recommend having a professional handle it, but don't be afraid to give it a shot. 

We have a Do-It-Yourself Guide that has a lot of useful information.

We also have a Tool Rental Service to help you get the tools you'll need to pull this off.
