Thinking about opening up your home? Know the wall first.

Get the free Load-Bearing Wall Checklist. A one-page guide to tell whether a wall is holding your house up, what a proper open-concept job includes, and the questions to ask before anyone cuts.

Hi, I am Lior Mazor. I run Hillstar Construction, and I build and remodel homes in the San Fernando Valley.

Almost everyone who wants open concept starts with "I just want to take out this one wall." The honest first question is whether that wall is carrying your house, because the answer changes everything about the job. So I put the way I read a wall onto a single page you can use before you spend a dollar.

What is on it:

• The clues that tell a load-bearing wall from a plain partition
• A quick two-column check so you can get a first read yourself
• What a complete wall-removal job actually includes, beam, posts, load path and all
• The exact questions to ask a contractor before anyone starts cutting
• The right order of operations, from reading the wall to finishing the room
• How to verify the licence of whoever you hire

It is free, it is written for homeowners rather than for contractors, and it is short enough to actually use.
