"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."

The work was performed quickly and skillfully, with great results. They also turned the double door leading into that room into a single door, creating more space in the room. Concurrently, in the guest bathroom, the old tub was removed, and a beautiful walk-in tiled shower was installed, along with a window with a fantastic view.

FAQs for basement remodel projects in Union City, CA
Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:
Replacing insulation
Replacing carpet or other flooring
Adding heating and cooling
Adjusting or adding walls and doors
Altering or adding plumbing elements
If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:
Painting walls yourself versus including in the cost of the remodel
Installing light fixtures yourself
Choosing prefabricated fixtures, like cabinets, over custom ones
Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
