They were very good at steering us away from mistakes, but also at working with our specific style, budget and timeline. > > 5 stars overall, but I want to give a little detail on the things that went particular well or that were a little bumpy: > > Carpentry work: Excellent, on time, high quality. Great repair to old closets, install new doors, replace or repair a bunch of termite-damaged beams and wood, replace lots of paneling and more. This made a huge difference in the house! > > Earthquake safety: We had them open up the walls, add new shear panels, and bolt the foundation much more securely than it had been. Excellent work. > > Insulation: They added additional insulation in many of the walls (Eichlers are notorious energy inefficient by default), and helped us make choices around improving efficiency in general. > > Roof: They subcontracted most of this work. The price was better than other estimates we got, and it looks pretty good up there. No concerns. > > Electrical: They subcontracted to Serge Jullia, who always does excellent work. They coordinated with him quite well. There was a lot of electrical work. > > Bathrooms: We didn't fully remodel the bathrooms, but Keycon made them much nicer with the addition of tile floor, grout repair, sink replacements etc. > > Plumbing: They did some of the basic plumbing, but I had to bring in a separate contractor for the more complicated work. > > HVAC: We asked to have a ductless A/C installed with two head units. They subcontracted the work. This took much longer than expected, and the subcontractor had to return a few times to fix leaks or loud noises in the head unit. The second head unit still needs to be installed (it was backordered). The end result for the first head unit has been good, and the price was fine. > > Garage door: We installed a new garage door for better sealing against rodents and such. Keycon subcontracted with Econo Doormaster, and they did a very good job, though it was a little more expensive than we had initially expected. > > Coordination with other subcontractors: We had other contractors do painting and glass work, and Keycon coordinated quite well with them as needed. > > We will definitely choose Keycon again the next time we need a general contractor. **★★★★★ — Bay Stone Depot, May 2018** > We have worked with Keycon several times and have found them to be professional and responsible. They are attentive to their customers and operate at a higher level. We hope to continue our relationship with them and very proud to be associated with their level of quality. **★★★★★ — Marlene Perl, Dec. 2013** > I wanted a master bathroom remodeled. Working with Ron Key's recommended design specialist, we accomplished everything I wanted incorporated into my newly designed room. I consider it a splendid addition to my home. Ron, his crew and his sub-contractors were always respectful, pleasant, prompt and very competent. My bathroom now has heated floor, heated towel bar, Kohler combination bidet/toilet with heated seat and remote control, a roomy shower with river rock floor to assure non slip surface, built in marble seat, shower heads on the Grohe wall panel plus a hand-held shower head that hangs on the same panel, custom made counter and flush drawers and cabinets that provide an appliance outlet and storage for a hair dryer, built in hamper and sufficient storage for towels, make-up, assorted bathroom items, eg. soaps, lotions, bathroom tissue, etc. and, very importantly, lots of mirrors both over the counter and baseboard to ceiling adjacent to the counter. Great for checking overall appearance and, incidentally, add dimension to the room. Ron also pointed out the importance of having grab bars installed in the shower for safety. I appreciated that. ## Selected projects - [Playful Open Concept - Sunnyvale](https://www.houzz.com/hznb/projects/playful-open-concept-sunnyvale-pj-vj~7875913) - Location: Not specified - Photos: 9 - [Sunnyvale Modern Kitchen](https://www.houzz.com/hznb/projects/sunnyvale-modern-kitchen-pj-vj~1513477) - Location: Not specified - Photos: 6 - [San Jose Modern](https://www.houzz.com/hznb/projects/san-jose-modern-pj-vj~1513396) - Location: Not specified - Photos: 8 - [Sunnyvale Modern Bath](https://www.houzz.com/hznb/projects/sunnyvale-modern-bath-pj-vj~1513384) - Location: Not specified - Photos: 4 - [San Mateo Modern Kitchen](https://www.houzz.com/hznb/projects/san-mateo-modern-kitchen-pj-vj~1513323) - Location: Not specified - Photos: 6 - [San Mateo Modern Bath](https://www.houzz.com/hznb/projects/san-mateo-modern-bath-pj-vj~1513318) - Location: Not specified - Photos: 8 - [Palo Alto 2 Eichler Kitchen Remodel](https://www.houzz.com/hznb/projects/palo-alto-2-eichler-kitchen-remodel-pj-vj~1513304) - Location: Not specified - Photos: 7 - [Palo Alto \| Eichler \| Kitchen & Bath Remodel](https://www.houzz.com/hznb/projects/palo-alto-eichler-kitchen-and-bath-remodel-pj-vj~164588) - Location: Not specified - Photos: 4 - Description: kitchen - [Palo Alto \| Eichler \| Kitchen Remodel](https://www.houzz.com/hznb/projects/palo-alto-eichler-kitchen-remodel-pj-vj~164595) - Location: Not specified - Photos: 3 - [Cupertino \| Eichler \| Kitchen & Exterior Paint](https://www.houzz.com/hznb/projects/cupertino-eichler-kitchen-and-exterior-paint-pj-vj~164574) - Location: Not specified - Photos: 9 - [Sunnyvale \| Eichler \| Kitchen Remodel](https://www.houzz.com/hznb/projects/sunnyvale-eichler-kitchen-remodel-pj-vj~164594) - Location: Not specified - Photos: 5 - [Palo Alto \| Eichler \| Proposed Whole House Remodel](https://www.houzz.com/hznb/projects/palo-alto-eichler-proposed-whole-house-remodel-pj-vj~151028) - Location: Not specified - Photos: 10 - Description: Proposed whole house remodel+addition to an early Anshen+Allen designed Eichler in Palo Alto, CA - [Palo Alto \| Eichler \| 2nd Story Addition](https://www.houzz.com/hznb/projects/palo-alto-eichler-2nd-story-addition-pj-vj~152233) - Location: Palo Alto, CA - Photos: 9 - Description: Whole house remodel + 2nd story addition - [Sunnyvale \| Eichler \| Carport and Kitchen Remodel](https://www.houzz.com/hznb/projects/sunnyvale-eichler-carport-and-kitchen-remodel-pj-vj~151896) - Location: Sunnyvale, CA - Photos: 6 - Description: Converted the existing 1 car garage and carport into a 2 car garage.
