He laid out a plan of attack to repair / replace our foundation along with new footings, drainage inside and out and two new pumps. He was in constant communication with us. Martin Cruz and his crew came in and stabilized our house until the official work started. Once the building permit was in place, Marin Cruz and his crew went to work. They did a great job of leveling out house, putting in new footings, drainage, and two new sump pumps. Outside they grated out the yard, new top soil, grass seed, and covered with straw. Martin Cruz answered every question we had. We couldn't ask for better!

In the two emails and two texts I received from them with appointment details there was no after hours line or way to contact them at all.

tl;dr - Avoid this company at all costs unless you want to risk having your home damaged for work…read morethat could charitably be considered low quality. "More like the Home Destroyer" is what another contractor stated once they saw the work that was done in our home by The Basement Transformer also know as The Home Transformer. I will admit that they are very slick salesmen, able to sell you on promises of all the great work they will do to completely transform your space, and they seem to be the exclusive distributors of several products that are waterproof for finishing areas of a home that may get wet. In fact, we spoke to John after we suffered a devastating flood that destroyed the ground floor of our home, and requires extensive work to make it usable again. They came in and assessed the issues and presented some solutions. As we weren't quite sure what our final plans would be, we figured we would stat with getting a cement floor poured. First up was the demolition work, which took much longer than was expected, largely due to scheduling issues they were having because they "had so much work" and were short staffed. The people who had been doing the work even ended up quitting the company even though we had been told they had been working with them for years. They did a lot of unnecessary demolition such as taking down the upper cabinets from our former kitchen, which suffered no damage, likely to justify charging us nearly $10k for a job that other contractors told us they would have been able to do for a quarter of the price. Then came the floor, which was so poorly poured that I'd have been better off doing the work myself. The floor poured is so uneven that I can't put down a 4' level anywhere on the floor where I don't get a big gap under it. Beyond that it seems they didn't even screed several sections, and they left behind swirl marks in sections where they did screed. While that would be bad enough, they later tried to "fix" the poor work they did by grinding the swirls out. However, when doing that work, they failed to isolate the work area, and we ended up getting a massive cloud of silica dust that was so thick it set of smoke detectors two floors up from where they were working. All of our belongings were covered in silica dust that we're still dealing a year and a half after the fact, creating a situation that might have played a role in a really bad cough I developed. What really set these guys apart was just how rude and nasty they got when we were trying to come to a resolution with them for the damage they did to our home and it's belongings, claiming that the issues were our fault because "we had too much stuff" or implying that we were having money troubles. The solutions they did offer were entirely inadequate at addressing the issues they created, and they stopped communicating with us once we told them how much it would cost for them to properly clean up the mess they created. Orange County doesn't have licensing for contractors which is probably the only reason they are able to continue to do business. If you're thinking of doing business with this company, ask yourself if the risk of damage is worth it.

Overall terrible experience - from trying to get an itemized bill for insurance (3 versions, still not itemized. Gave up asking.) They demo'd walls and all window treatments (we did not ask for and I cried), dumped a full truckload of gravel in our driveway - a year later - we still don't have access to our full driveway (after moving half of what was left behind!). Not one spot of the 700sq feet floor is level. There are ripples big enough to trip over, so they decided to SAND DOWN the CEMENT ripples, but FAILED TO PUT UP ANY BARRIERS - NO PLASTIC. SILICA COATED THREE (3) floors of our living area. I had them stop work when our smoke detectors started going off on the 3rd floor. I was outside clueless. My partner called me because his phone was going off saying there was a smoke condition. I walked inside to a ball of dust. I called John from outside immediately... because no one but 2 workers were here and there was a language barrier. "Some dust is to be expected." I replied quite confused and upset at his lack of understanding...as we had b waiting 4 months for the sanding. It was a big day for us. A useable floor. I replied to John with a bit more urgency and pictures. Many pictures... "This isn't some". John said it was safe to enter. And knowing better I said, "No. You don't understand, you need to get over here immediately." I called my partner, told him John said it was safe to enter? My partner and his coworkers in construction said to vacate, get the pets, computers, etc... because it's toxic. I sat in the car with 3 pets, took a business meeting in the car, and then demanded they clean and put us in a hotel. Reluctantly, they did. Still continuing to refused to give us their insurance information... They hired local cleaners to spot clean, but refused a deep clean. Cleaners didn't even mop floors. 8 hours isn't enough time to clean a toxic silica mess. $20k concrete floor Unfinished and not functional Partner needed a nebulizer (thank God, no kids here) Work Started 1 year 7 months ago Work Stopped Multiple Times - excuses always they same -people quit/fired, -out of state meetings, -multiple excuse (at least four (4) times) of 'too busy with other clients' *while they had our money* They stopped working completely after silica dust fiasco with no remed, leaving us without a usable floor, spending an additional $1,500 in air quality testing, health hazard, pollution inside, and now a fully wrecked 3 floor house, everything we saved from the flood instead was made exponentially worse.

Last October or so, we had a huge rain (not this much), and our basement got soaked. we lost a lot of memories that we foolishly stored in the basement. Anyway, we reached out to a couple of well-known basement guys to permanently fix it. We stumbled upon United Waterproofing.. Matt, Jason, and their team came over within a day, impressively quick, and offered us multiple options. Within a few weeks, we got the French drain installed, and since then, we have had no issues with the basement. I thought of sharing this shout-out with a local small business. If anyone needs help with the basement, you can rely on these guys.
