Family owned business with over 22 years of experience -Remodeling - General - Remodeling - Kitchen & Bathroom - full home remodels - room additions - ADU's - Full Roof replacement -
"Would not recommend them to anyone. We had the worst experience with these guys. Scope of project: kitchen complete remodel, replacing carpet flooring with vinyl tile flooring , redo electrical for kitchen area only cost: 100K+ what went to plan: - kitchen demo - made one nice dry wall - setting up and framing of the kitchen area what went wrong: - communication/scheduling : we would never be told ahead of time when work was being done. Sometimes there would be days stretches where no one showed up and then guys would show up randomly on a Sunday morning. At the start of the project we told them we were going to move into the back half of the house, so just have that clean. We moved into trash and debris everywhere. They also saw a vinyl strap , strapped to our tree, tied to our neighbor's fence (it was there keeping the fence up as the tree was leaning into the neighbors fence). In their brilliance, they decided to cut the strap and use it for themselves. How did we know? we found it on our roof, used to tie some electrical conduit. Who the heck does that?! We should've cut ties at that point, it was just the start...if we only knew. But we gave them the benefit of the doubt...but things kept going wrong. - Kitchen cabinet install was not leveled, we end up telling them to not bother coming back and we installed the whole kitchen ourselves (re-leveling the base cabinets, putting on the hardware, installing the cabinet doors. - broke several custom panels (to their credit, they did pay for the reorder) but we ended up installing it ourselves , which we were never offered refund the labor. - the kitchen counter was not leveled, we also had to redo it ourselves in order for the independent countertop guys to install it. - cut hole for electrical switch too big, huge gap now in our org Eichler panel that is not repairable unless we replace the whole wall. - cut hole in wood beam ceiling too big for ceiling vent even though they had the manufacturer's specifications. tried to fix it, but it looks terrible. - lied and said they had experience installing lux vinyl tile. They didn't. The flooring , which is supposed to be new, looks like flooring that has been there for years and hadn't been replaced. It was discolored, uneven, not leveled, and not even lined up. How can you mess up lining up squares? Our sales person Joe ,came and made excuses after excuses , telling us " no one can install it better than them" , that this is the "best" we'll get. I cannot believe he could look us in the face and say that. We ended up requesting 1500 back, though for us to reorder redo the tiles for the kitchen will be 3K+. - as a last F you to us, they gave us the bill for the permit fees which includes a 3% of project cost recycling deposit that is 100% refundable if they just do the paperwork and let the city know where they recycled the demolition material. Our kitchen project was 80K and so it was $2400. Guess what, they "never heard of this" and have no proof of where they recycled the material and so cannot get the refund. I have no idea where they dumped the material.....and we're out 2400. The best thing about this project is finishing and NEVER having to deal with them again."

"Oscar and his team came highly recommended from a friend whom he previously did work for. he was always quick to respond to my questions leading up to the job, and gave me a quote which he stood by. i hired Oscar's team to replace a 17 year old water heater. His team was professional, efficient, and arrived to do the job done on time and finished earlier than expected. also, he offered a very fair price for the replacement that was much less than any one of the other businesses i received a quote from. i wouldn't hesitate to use him and his team in the future for jobs like this or remodeling. it's great to support small businesses like his.

"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 leak repair services FAQs
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.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
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.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
