"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 were looking to remodel our kitchen or bath for a few years. We kept getting estimates from different companies and always felt the price was off or the person was not a good fit. Then, finally, we met Shai with Cal Green Remodeling. What a great guy! He is very upfront and honest about what we can expect in terms of cost and work flow. Because of his honest approach, we hired him. We felt he gave us the good and bad and how to resolve the bad as well. In the end, the process was fairly smooth, and the few hick-ups we had, for example, the city and their permit process, were well explained to us at the beginning, so we were ready. Our kitchen or bath looks amazing, and I plan to work with Cal Green Remodeling again. Thanks Shai!"

Basement Remodel questions, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

It may not come as a surprise that the kitchen is the most expensive room in the house to renovate. This is due to the expensive appliances like the range, hood, and fridge, but also because the bones of the room—like electrical and plumbing—are expensive to move or replace. While there are ways to renovate a kitchen on a budget, it will always carry a hefty price tag, even if you cut some corners.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Yes, finishing a basement is worth the money in most cases. Although the project is a relatively expensive one, finishing a basement adds usable square footage to your home and typically increases your home value. Many times, your finished basement will add value that’s equal to or greater than the cost of finishing.
