"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."

Addition to existing structure building services FAQs

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
