We had a lot of root infiltration in our sewer lateral so it had to be completely replaced all the way out into the main city line in the street. They were great to work with.

The whole team was really nice to have around and cared about doing the job right. Thank you Diamond D!

I several years ago contacted this company to clean the roof of my house. They did an excellent…read morejob. Later on I needed some plumbing work done, I made several calls to their company but never heard back. Two days ago I contacted them again for a plumbing issue. The man on the phone asked if yesterday afternoon or today (9:30 am) would be better. I said today would be fine. 9:30 am came and went. I made several calls to two different numbers yet I was never able to contact them or get a call back. This interaction has proven that even though they did an excellent first job, it is a waste of time trying to contact them again. As much as I hate to do it, I am forced to rate this business as a one star due to a lack of communication and a less than decent effort to return my calls. If you can get them out to your house you will get great results. The trick is, getting them there to do the work. I won't make the mistake of contacting them again.
