Your Local Home Services Provider Since 1995

Castleworks team standing next to service vehicles

Our story begins in 1995 as Affordable Water Heaters (AWHAP) with inspired entrepreneurs including Lee and Christy Roux, Steve and Wendy Moore, Bill and Amy Tassio, David and Eliza Parker, and Danny and Kate Guiney. Each of these couples started from humble beginnings, building their family-owned and operated companies from the ground up in their various fields of expertise. Over many decades, their successful businesses provided expert plumbing, air conditioning, heating, and water heater services throughout California.

In 2020, Dubin Clark partnered with us for our next stage of growth and took on the name CastleWorks. We felt their expertise in specialty services would help guide and support our growth and expansion without compromising our reputation for high quality and excellent service.

CastleWorks has served as a leading, in-home service provider for same-day/emergency water heater replacements, gas and electric water heater repair and installation, tankless water heater installation as well as a variety of others water heater and plumbing services.

They replaced our water heater and installed some new venting and water piping. Also, new valves. Julian was great at what he did as well as being a very nice person. The... company was somewhat pricey though, as I was charged $4,287.00 for the new equipment and installation. Also, I wasn’t given an itemized receipt, although I was told I could call the company and ask for one.read more
