Marc was extremely honest and professional. He thoroughly inspected my sprinkler system after I was concerned about saturated soil and possible water leaks. Unlike others who tried to upsell unnecessary repairs, Marc determined there was no leak and explained that limited sun exposure was delaying the soil from drying. He didn’t charge me anything and saved me from unnecessary repairs. Highly recommend Marc if you want someone trustworthy and knowledgeable.

Details: Residential • No sprinkler system maintenance needed

Marcelo did an amazing job replacing old and broken pipes. He also corrected some issues that were created by a prior person who installed a drip line. He is not the cheapest but really knows what he is doing and takes the time to do the job correctly.

Details: Residential • Sprinkler head is broken

Marc was fantastic. MCS Building did an excellent job on our irrigation system. Marc replaced some sprinkler heads, fixed a few leaks, and installed a new timer as well as a few other things. He is very skilled and professional. The pricing seems extremely fair, and I plan to use him for future work. Highly recommend!!

Details: Residential • System won't turn on • No water to one area of sprinkler heads • Timer does not work • Timer needs to be reprogrammed • Spring activation - system needs to be reactivated
