"We had a sudden sewage back up into our home. I called C&G and they responded right away. They were very respectful and helpful. Though the problem was far more extensive than originally thought, C&G completed the repairs quickly. I will not call anyone else for plumbing services. The owner is very professional and knowledgeable."

"Our plumbing was shot. We hadn't been able to flush tp or run the shower and laundry at the same time in years. All the other quotes were so high we couldn't afford to fix the plumbing. Our last quote was Mike and we couldn't believe how reasonable his quote was. Literally several thousands under the competition. After he was under our house he found that we had several more pipe rot and breaks than we thought. He showed us the pipes. Mike was reasonable again with the price. He installed an entirely new system for thousands less than the others. He went about it in a smarter way too. After he was finished we found more problems outside the house. He fixed that too! He answered all our questions. He has patience. He worked with our budget. I plan on using him in the future and would recommend to anyone."

"This was a tough decision for me to spend a lot of money to fix my seeer line. But the people at Mother Modern made me glad I did this, that I chose them. Tyler was top notch and Jerry was the best plumber I have ever hired and the excavation crew were the best."

"The installation itself went well, and the additional items promised were received. We negotiated for more items since we didn't need an additional RO filter. NOW here is the BUT. We do have satisfactory whole house basic filtration, BUT it adjusts the pH the wrong way for us. Sales person tested water but I don't think she was used to seeing high pH like we have out here. We really needed a different solution to take care of that, but that wasn't suggested. So our water is even softer now. This keeps us from being satisfied with what is a good product otherwise. Last periodic servicing January 2017, satisfactorily performed."

"Stuart HVAC, LLC Was amazing.  Stuart's knowledge, professionalism and attention to detail saved me time and money.  The man really knows his AC and heating.  He did so well on my air-conditioning system replacement that I had him come back out and replace my hot water heater.  All of which are working perfectly! 
I would recommend him to anyone who is seeking an honest, hardworking and skilled person in this area.
Regards,
Leslie

"Checked the entire house and water heater.? We discussed the water in depth, it would need to be replaced in the next year and it was 10 years old, at the end of it's life.? Adjusted all toilets and installed two new flappers, so the toilets don't run constantly and saves water.? Checked the shower and replaced the shower head.? We were entirely satisfied with the service."

"The services and work that Francisco Albaran offers to his clients is outstanding, extremely professional, respectful and friendly! I had a problem with my water heater and my plumbing in one of my showers. He was able to fix it and complete it thoroughly, which other companies couldn't and seemed like a big problem, he was able to do it! The service was quick, easy and inexpensive. You can't go wrong with it! Highly recommended !!"
