You could not ask for a harder-working, more conscientious, or more honest "old school" gentleman. He does not deal in contracts but in mutual trust and reliability. His word is his bond. The only "negative" thing that I can say about him is that he sometimes spreads himself too thinly by never wanting to say "No" to anyone, so you may have to wait for awhile to get your job done, although I'm sure that if you specified when it needed to be accomplished you would be satisfied. Jim Carlson and his son are highly experienced, very courteous and professional, and work very hard and persistently. James Carlson and Son removed our old septic system (which had started to leak due to our water-treatment back-washing into the septic system), and installed a new state-of-the-art system. He also installed a new dry-well for the water treatment back-wash, separate from the septic system. He covered everything with new, screened topsoil, re=seeded the yard, and covered it with hay. Then he paved the parking area with chipped asphalt. He cleaned everything up so that he left our yard looking better than when he arrived. He has a good working relationship with both state and local health and building authorities. He got all the permits, and had all the inspections, without any problems. If you need a septic system repaired or replaced, or need any excavating work done, I would highly recommend James Carlson and Son. We will use him again in a flash.
