"John and Derek went ABOVE AND BEYOND with our bathroom renovation! Their attention to detail and quality work really shows! John did EXACTLY what he said he was going to do. They got the job done before Christmas! Very rarely do people exceed my and my wife's expectations. Custom Valley Construction did exceed all our expectations. We are looking forward to hiring them to build a 3 car garage and attached casita in the new year. I highly recommend them for any construction project. Thank you!"

"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day. There was a deadline for installing this part before tenants arrive. They did not care, would not m"

"My fireplace decided to go into alarm mode during the HEAT of the summer! Even though their technicians were BUSY helping people with cooling issues, they made time to squeeze me in.

"I have been a faithful customer of Grassi’s for 5+ years. They’ve installed 3 systems for me and serviced 4. I am a small business owner in town and don’t take negative reviews lightly. As of today, Grassi has lost me as a loyal customer. Over the past 6 months we’ve had consistent issues with a couple systems (5+ call outs to 2 properties). To their credit, since the units are under warranty they say they will warranty the parts. Even still we are at $1,700+ costs thus far. Today, our tenant was cold and turned on the heater. It is 60 degrees outside. Grassi is charging for another callout as the units that they worked on within the month threw another code. Their technician, Cody, called us and told us that this is an operator error, blaming our tenant for their machine malfunction, as these are “not designed to heat when the temperature outside is above 60”. These are the only heat source for the house as recommended and installed by Grassi. What is our tenant supposed to do? I don’t believe this is an engineering issue as I have more faith in Carrier (the brand installed) or my tenant, who deserves to be comfortable. My take is that this was either poorly installed or poorly recommended. When asking more questions Cody, the technician, told us that we knew nothing about refrigeration and hung up on us."

"Great! Scott did a quality job and was very easy to work with. The best part was that he was very clear in his pricing, itemizing every invoice and reviewing it with us before every payment that was due."
