"Very pushy Project Managers gave us the creeps. We felt threatened, that if we did the work w/out permits that they would report us. They kept on touting their great s/w for project tracking. So spooked with didn't want them in the house again. In fact, they brag about their military training that helps them manage projects . Perhaps that's how they strategically coerce people...my wife and I certainly felt threatened and wanted nothing further to do with them. Not surprised that Yelp has posted a notice of suspicious reviews."

"A few years ago we did a simple remodel of two bathrooms in Menlo Park with FVR. By the time we finished the project we just wanted these folks out of the house. After a few years I felt it was necessary to share our negative experience and how poorly much of the work has held up. Specific issues; 1. Substandard workmanship: a. Heating vent under the house was left unconnected--I was heating our crawlspace and not the bathroom for 6 months. This went undetected until I went under the house for something else! b. Looking in my attic, the electrical work to hookup the bathroom fan is clearly not up to code--junction box is not closed and there are multiple exposed wire splices. c. Gang box for the newly installed light switch is clearly not level and out of square. 2. Numerous examples with low quality finish carpentry: a. Gouge on a newly installed sliding door from the aluminum frame--supposedly fixed then recurred. b. Spackle and paste used to patch the casing around the door frame where it contacts the bathroom tile--looks terrible c. A supposedly 'straight' wall that was rebuilt by FVR, clearly bulges with an obvious curve in the baseboard. d. Sloppy work on the plumbing cover plates for one toilet--half smeared with paint and not attached to the wall properly. 3. Low quality of painting: a. Two slightly different colors of white used in one bathroom with sloppy caulking around the trim. b. Numerous blotches of paint on hardwood floors around the hallway baseboard--the kind that would be easily have been avoided by using masking tape. 4. Sloppy personnel and poor cleanliness: a. Folks were working while we were on vacation, and we came home late in the evening to find construction debris scattered in our front yard including razor blades, paint on our front walk (where stains can still be seen). b. For a year afterwards we found trash (food wrappers & empty bottles) behind the bushes or buried in the shrubs. c. I saw workers 'free handing' a circular saw for trim and baseboard--where one guy would hold the boards and another would use the circular saw. For sure not a safe or effective option--just glad nobody was hurt at our house by these substandard practices. Nobody could be bothered to bring a jobsite saw. I will add that we pointed out most of these issues to the company reps while they were happening-- most responses 'Just an honest mistake' and/or 'We will send somebody over to fix that'. At a certain point you stop trusting anyone from the company and just want these 'less-than-competent' folks out of the house. The customer shouldn't have to check all these details--especially about heating/plumbing/electrical work. Would not ever trust this company again to touch our house."

"We recently had our house remodeled by Bark and Build. The work included kitchen, interior painting and refinishing the hardwood floor. When we first met Mike, we knew we are in good hands. He listened carefully of what we wanted, attended to all the details before he provided us with a fair estimate. Mike cares about our house. He suggested us to complete the re-wiring of the electrical which was not in our plan but was much needed. We had a very good experience during the entire project. Mike and Miki’s dedication to make their customers happy was incredible. Unforeseen issues happened and they were quick to resolve them. The results of the work met our expectation. It was such a great pleasure to work with both of them!"

"Ken and his crew built me 2 beautiful bamboo decks. One large and one small. They also replaced all the plywood and siding on the back of my house. Our upper deck, which is the larger one has a water drainage system so we can have a living space underneath. The lower deck, which is the smaller one is flanked by concrete planter boxes and looks awesome! Despite last winters heavy storms, they got the job done quickly and efficiently."

FAQs for addition to existing structure building service projects in Santa Cruz, CA

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
