"I really needed my outside faucet replaced, it was not working properly and was very hard to turn off, to prevent leaking. I called Excalibur Plumbing and they sent Curtis out to fix my issue. He was very friendly, courteous and easy to work with. I use this faucet a lot in the summer time to water my flower bed and my yard. It's now working better than ever! Thanks Curtis!"

"Just had a/c system replaced a couple of days before and the employees from that company were more concerned with leaving their work area clean. Price seemed rather high."

"Two young men arrived, identified themselves well, brought the parts needed as requested and got right to work. They were efficient and professional and answered all our questions clearly while progressing with the work. They shut down the house water and worked efficiently to complete the job. They removed the old spout and valve, inspected and repaired the old plumbing located behind the old fixtures, and installed chromed plated fixtures that met our expectations splendidly. We were given the cost for the parts and for the time it took to install and we paid with a check on the spot for the service rendered. Everything was well organized and executed. We would suggest them to anyone."

"Justine from Prostar was very knowledgeable and professional. She gave us great price options and followed up after the installation to be sure we were happy. They were on time and did a great job! The technician thoroughly explained what they were doing and how long it would take. We had several quotes/options, but Prostar Water definitely provided the best product and service for the money!"

"I had a water heater fail on a Sunday morning. I submitted a request and got a response in less than a minute. The person was extremely helpful and we arranged an install only a few hours later. I couldn't be happier with the service and attention to detail. *This review was migrated from an affiliated account on Angi with an original submission date of 2/18/2021."

"We had a leak in the wall between the large bathroom & my study. The original contractor disappeared on us. When we alerted on Angies list (home advisor) we got calls from 3 businesses & met with all 3. We chose Canco Construction. They quickly began the build back in the two rooms damaged from the water leak. We are very pleased with the work done. They worked with us to achieve what we wanted from the job. The pack up, furniture removal & replacement was carefully done. Every time I walk into one of those rooms I smile at the beauty of the. repair. Thank you .Kenny,Tony & crews."

"Jeff was great. We had two other roofing companies make repairs on a leak, and it was not fixed by them. When Jeff came out, he was able to spot a possible problem area right away. The person who did the actual repairs was very thorough. He did find an issue and corrected that problem, did an overall check of the rest of the roof, and corrected some other areas. We were pleased with the company overall."
