"It went very well. John was very professional, pleasant, courteous and fast. He even made a trip to Home Depot to purchase faucet tube nipples to prevent future kinking, as was one of the problems with the water pressure that I didn't even realize I had. He also replaced the water valve under the sink for me because the old one was worn and could possibly leak. Absolutely pleased and I would highly recommend."

"Personable, easy to work with and good listeners. I was pleased with the installation of the tankless water heater. It was professionally done, appearance of piping was good and upon completion they left the work site clean. Advised on other plumbing projects that could be beneficial to me and I appreciated the fact that Caesar corrected a wrong installation under the sink. I definitely and highly recommend Cal-Tech to friends and anyone who needs any sort of plumbing projects done. LNT :)"

"Can not say enough positive things about this company. Usually do alot of things diy, but i would hire them any time to do plumbing. Their professionalism is way above board. Prices more than fair. Miguel is a definite asset to this company. When i have a plumbing problem i will definitely call them back. (had another company come before them that could not get the job done and suggested replacing the trap under my bathtub. My home is not on a foundation but a slab, and that means removal of my bathtub. The cost of his visit would have gone from one hundred dollars to thousands. ) Thank you Service Champions!"

"Yes. It was a tricky job failed by two prior plumbers we hired (not from Angie). Albano Plumber was very good in making the effort finding the root cause and get the job done right."

"I thought this company did a good job. They put in the furnace and it seems to work. The problem is they never got a permit for the work. Then they never got the inspection from the city. Both the permit and the inspection were part of the contract. I do not know anything about furnaces or furnace installation. Without the inspection, I do not know if the furnace was installed correctly. Is it sending carbon monoxide into our house? I must have called them 100 times in the last year to get the permit and inspection. they simply refuse. I have sent a complaint to the contractor state license board, I do not recommend this contractor."
