Obsta was at my home in June of this year -,2016. An apprentice-I assume- did the work under the supervision of another plumber.. I had reported 2 faucet fixtures that were leaking and issues with the drain stoppers not holding water.I was told the kitchen faucet needed to be replaced, but went ahead and let them install new turn off valves in the kitchen due to their age and condition. Later I purchased a new faucet on my own..They replaced a flapper in a bathroom that is seldom used- charged $85 for that. Bathroom sink cold water faucet was leaking. They needed to replace it with a cartridge-something I was not familiar with.They did not have the cartridge in their truck so they left and returned with 2 new cartridges and installed them. The cost of the cartridges was excessive. I could have purchased 2 new fixtures for what I was charged for those 2 parts, and I feel that I should have been advised of that before they left to purchase the correct part. They adjusted the two drain stoppers-one wasn't attached at all the the second was too low. That took 5 minutes, but unfortunately they didn't ask me to try them and check the speed of drainage, so now both are on the slowest setting possible and take forever to drain, so made the problem even worse. That evening I noticed that the cold water faucet that had a new cartridge was still leaking, so I called and they returned the next day and tightened it-no charge.The pricing for this amount of work,I felt was extremely high, so I will not use them again or recommend them.
