"Keep smiling was prompt and performed the work as quoted.They added a new outside wall faucet in a location near our pool so I don't have to run a mile of hose when needing to add water.Also, they had previously diagnosed why our "builder installed" recirculating hot water system did not help distribute hot water through out the house. The pipiing was installed in a poor location for gravity-feed and the builder had failed to add the pump itself.On one end of the house hot water would need to run for several minutes for it to reach the faucets.Keep Smiling corrected the piping design and installed the pump.Now we have hot water through out the house even in the longest runs in seconds!Great experience and will use for all our plumbing needs."

"Scheduling was easy and they were on time for our appointment. Price for replacing our water heater was as quoted and very reasonable compared to other local plumbing services that quoted the same job. The water heater is a name brand with a warranty. All in all, Miley Plumbing was respectful of our time, our home, and provided quality service at a reasonable price. Plus, they are just good honest people."

"The reason why I give them 5 stars is because they respond and install my water heater in Less than 24 hours. The technician who run my call show that he has knowledge about that job. When the job was done he explained how the new water heater work and what to if help is need it. He also explained and showed me the deficiency of the valves and recomended to be changed. I when ahead and take his recommdation. I took their number from the broken water heater that was installed 23 year ago. If I ever need plumbing service I will call then in a heartbeat."

"Rooter ProXpress was cordial, efficient and very professional. I hired them to remove my tank water heater and install a tankless water heater. The plumbing technician came out to evaluate the work to be done. He was very knowledgeable and said I would need an electrician. The electrician came the following day and explained in detail the work he needed to do. The following day both the electrician and the plumbing tech came together and installed the tankless water heater. I was very pleased with their work and professionalism. I will use Rooter ProXpress for future projects and highly recommend them."

"Outstanding company of real professionals. Work performed: 1. All power receptacles and switches were upgraded (new parts replaced old, wornout parts). 2. Assembled and install two (2) new customer supplied ceiling fans . 3. Provided and installed new 15A convenience 0utlet. 4. Provided and installed single pole 15A/20A arc fault breaker I have an eye for detail. Minor discrepancies leap out to me as well as minor work done well. Perhaps, twenty-two years in the military created this effect upon me. Sometimes it's a blessing and sometimes a curse as I find myself unable to accept minor, shoddy work. Example: All of the screws to the new face plates for receptacles and switches were oriented with the screwdriver slots in the vertical position. This was not done by chance by the team's three electricians but by their attention to detail and uniformity. If the small things are done perfectly, I feel it is safe to assume that all of the larger work is too. I have four more electrical projects to be accomplished and TE Certified Electricians will be my "go-to" company for these activities. I highly recommend TE Certified Electricians for your electrical projects."

"I used Greenlee to replace my water heater. They replied to my inquiry for service very quickly, even though it was after normal business hours. They were responsive and professional assisting me in determining the best solution for me. They arrived quickly and on time. Their work was fast and they did a great job of removing my old water heater and installing the new one. Everyone with whom I had contact was friendly and professional. They will be handling any future plumbing work that I have."
