Heating and Plumbing for Berkeley's Older Homes
Berkeley's older homes are some of the most distinctive in the East Bay. Craftsman bungalows in Elmwood and Thousand Oaks, brown shingles tucked into the Claremont Hills, stucco Mediterraneans in South Berkeley, and the older homes of Kensington, each with its own construction era and its own set of mechanical quirks. A lot of these houses are still running original hydronic systems that haven't had a specialist's hands on them in decades.
- Hydronic heating, boilers, and radiators
- Whole-house plumbing repair and repipes

What Our Neighbors Are Saying
We've worked with Mniska on the boiler/radiators in our new home and couldn't be happier with Mniska's attention to detail and communication. We cannot recommend his services more and look forward to a long term relationship with him over the years.
Afterglow heating provided us with thoughtful advice regarding our plans for radiant floor heat that saved us a ton of headache. They provide exceptional service with impeccable attention to detail. Highly recommended!
Mniska approaches projects with care, intensive attention to detail, and a laser focus on his clients' wants and needs--he's the definition of a consummate pro. Highest recommendation.
Mniska is a pleasure to work with- he is professional, knowledgeable, respectful, honest and caring. He helped me think through a plumbing issue with my shower and ways to save money with the repairs. He cares about providing quality work and approaches his clients with kindness and patience. I highly recommend!
Mniska installed our system about seven years ago. It's been problem free and very efficient.
It was great having Mniska make the required repairs to my washing machine, hot and cold water lines and fixing a new draining pan for the washing machine. He was excellent to deal with, fair price, and accomplished all the work in a quick and expedient manner. Highly recommended!
