The installation of the new faucets and plumbing assembly was perfect. They supplied all of the necessary parts except the faucets. They were very considerate, wearing overshoes to prevent tracking dirt on the floors. They were prompt. They arrived at the appointed time and they were courteous and professional. They cleaned up the mess that occurred while installing the new plumbing. They honored the Angie's List Groupon deal and deducted the specified amount from the total bill. They explained the cost of the service prior to beginning the job and they used high quality parts on the under sink plumbing and provided the new drain assemblies. After they left, we discovered a slight problem with the leaky shower that they had repaired. When we turned the shower from the faucet to the shower, only about half of the water was diverted to the shower. Apparently, one of the replacement parts had a flaw which prevented the full diversion of the water to the shower head. They returned the next day, took everything apart, reassembled it and determined that a replacement part is needed. They ordered the new part and are scheduled to replace it tomorrow. As stated above, the work comes with a guarantee and they have been very responsive in resolving the problem. Wilbur's did everything that they could to resolve the problem with the shower diverter but unfortunately the company that manufactured the original plumbing was sold to another company and that company's replacement part does not work properly in the old original plumbing. Wilbur (owner of the company) became involved and contacted several companies to try to obtain a replacement part that worked properly. He sent out his technician twice to try new parts. Wilbur called us personally to give us updates while he was searching for the replacement part. Although the problem was not resolved 100%, the most recent replacement part diverts almost all of the water now instead of just diverting half of the water. There is a small trickle that does not get diverted. The only possible 100% resolution would be to pull ot all of the old original plumbing and replace the whole shower plumibing assembly. That would involve tearing out a bedroom wall. We have opted to just live with the small trickle instead of tearing up a a wall. In my opinion, Wilber and his technicians did everything humanly possible to try to satisfy us. These people genuinely take pride in their work and they care about doing a good job. I should also note that the leak issue was resolved 100% on the original service call.
