"I have always loved building - when I was as young as 8, I was building tree houses and making ever more elaborate designs. My father was a builder and I learned the various trades from him and the contractors who worked for him. Building is in my blood and is my one true professional passion. I get the most satisfaction from building homes for families to enjoy and that can continue to be enjoyed for generations to come." - John ### Services Provided - • Custom Fine Home Building (new construction) • Major Residential Remodel • Historic Renovations • Kitchens - Baths - Outdoor Living Spaces • Light Commercial Build Outs ### Areas Served - San Francisco Bay Area-Atherton - Burlingame - Cupertino - Hillsborough - Los Altos - Los Altos Hills - Los Gatos - Menlo Park - Mountain View - Monte Sereno - Palo Alto - Portola Valley - Redwood City - San Carlos - Saratoga - Stanford - Sunnyvale - Woodside ## Business Details | Field | Value | | --- | --- | | Business Name | John Mansch Construction | | Address | 201 Los Gatos-Saratoga Road \#236, San Francisco Bay Area - Los Gatos, California 95030, United States | | Website | http://www.johnmanschconstruction.com | | License Number | 747292 | | Followers on Houzz | 16 | ## Contact - **Houzz profile:** [John Mansch Construction](https://www.houzz.com/professionals/general-contractors/john-mansch-construction-pfvwus-pf~755457557) - **Website:** http://www.johnmanschconstruction.com ## Reviews **Overall rating: 5.0 out of 5 — 2 reviews** ### All 2 reviews **★★★★★ — Mamta Jain, Dec. 2015** > John did a great job with our house. He finished on time and with in budget. He remodeled our entire house grounds up. He takes his job seriously and it shows. We are very happy with the results. It has been almost 9 years since our work was finished. However he is still a phone call away to help or answer any questions. Very sincere and honest. A pleasure to work with. **★★★★★ — arbyhuff, July 2013** > John Mansch Construction built a new home for our family in Saratoga in 2009. They took our previous 1600 square foot home; preserved some existing exterior walls (per our architectural plan to comply with City of Saratoga requirements) and expanded to approximately 3300 square feet of living space. > > JMC provided an accurate and realistic bid for our project and there were no surprises. The weekly billing method based upon work completed was straight forward and John's "open book" approach was clear and set us at ease that he was as careful with our budget as we were. Throughout construction and post-construction followups, John Mansch and his staff and sub-contractors were professional, ethical, meticulous and delivered our project on-time, on-budget, and with the highest quality standards. > > John Mansch clearly has a passion for building, has years of experience, and based upon our experience with John and his company, he gained our trust and gratitude. I give him my highest recommendation. > (Saratoga Creekside Photos are listed on the site). ## Selected projects - [Los Altos Custom](https://www.houzz.com/hznb/projects/los-altos-custom-pj-vj~2032077) - Location: Los Altos, CA - Photos: 19 - [Saratoga Creekside](https://www.houzz.com/hznb/projects/saratoga-creekside-pj-vj~204041) - Location: Saratoga, CA - Photos: 15 - Description: This custom creekside home in Saratoga was transformed from approximately 1600 square feet to 3300 square feet of usable living space.
