Jacob did a gutter and moisture level system installation. Shawn worked on the gutter installation.Both were very respectful of limiting the mess and dirt involved in installing such systems. Jacob made an extra effort to be sure that the moisture level system, installed in the attic, did not come in contact with anything in the attic, like a wood beam, that would cause vibration noise when it was working. Jacob left the inside of the house as clean as possible. Shawn installed the gutters so that they are up on the house to stay. All the outdoor trash from the job was picked up and removed.Barron repaired a large crack that was on the foundation. It looks much, much better and was ground down to an even level so I can install replacement tile. He also left the house as clean as could be in the circumstances.I would recommend them to others for the same type of work. They all explained what they did and what to expect. No one was EVER rude or lost their patience with my questions.The reason I gave a 4 was because the administrative staff was not very responsive. I was having 3 different jobs performed over 3 days and no one could seem to tell me, or even bother to get back with me, about which day what was going to be done. I also had trouble finding out what time in the morning the employees would show up for the job.
