  • "Mizen did a project for us on the front steps of our Victorian and we couldn't have been more pleased with the experience. We chose to go with them based on their professionalism and communication, and in the end we knew we'd made the right choice. Our overall expectations were truly exceeded by this team.""

    — Molly P

  • "We hired Mizen to do an almost complete remodel of our home. Their prices were extremely fair and they stayed within budget. No surprises along the way. They are very transparent with any problems that arise and always had options for us to choose from to continue moving forward. They are also a great group of guys. There work is top notch and l'd highly recommend working with them!"

    — Phillip

  • "Ciaran and his crew from Mizen are absolutely top-notch. We hired them for a complex, multi-unit renovation of our beloved 1920's era flats in the city. This involved everything from foundation and seismic work to full demolition and rebuilding of every aspect of the home. For one of the units this meant restoring complicated curved ceilings and original gumwood trim - done to perfection. Mizen's communication, craftsmanship, timeliness, and value surpassed our expectations. We enthusiastically recommend them to you for your next building project."

  • "These guys are very professional and 100% trustworthy. Their prices are fair and their work is great. Did I mention that they are trustworthy? In a city full of contractors that make the majority of their money by extorting their customers with ridiculous change orders and $100/hr subcontractors, Ciaran and Mark are a welcome addition. l've been burned by unscrupulous contractors in the past and will be using these guys from now on."

    — Raymond F

  • "We hired Ciaran and Mark for a small but complicated renovation of our 1906 home. They were great! Trustworthy, responsive, and quality contractors, that came in on time and on budget. I work with a lot of builders and these are some the best that I have come across in 10 years of construction. There team is also great. We were home with 2 young kids for a portion of the renovation and Mizen accommodated for us perfectly making it a much easier and low stress environment. Would highly recommend them."

  • "I can't say enough about Ciaran and his Irish crew. We had a 10 experience with this customer experience oriented team. We went through a full home remodel in Noe Valley. Ciaran was focused on making sure we stayed on time, within budget and that we were completely satisfied. I would highly recommend Mizen! These guys are amazing and fun to work with."

    — Glo G.

  • "I've worked with a lot of contractors on various remodeling and home repair projects over the last few years, and Ciaran and Mark from Mizen are some of the best l've met. An awesome experience from start to finish. I was truly impressed with the quality of the work and we absolutely love our new front steps. Without question, we'll be using these guys for all of our general contracting needs going forward."
