Review 1
Al was great, had time to pass by the same day I called him. Came over, did a thorough look and addressed my issue with a missing load bearing wall that caused my ceiling/roof to sink and crack. Recommended a great contractor that installed a new header and patched up my ceiling. Now I can rest easy at night.

Thanks Al,
I have more Almond Joys if you still need more.
