"Maurice (the owner) was extremely poor with communication. If he was so super busy, he should not not demonstrated interest in the project I needed to have done. Maurice came out on Friday June 19th at 3 pm and stayed for about two hours. He told me there's a cost of $45/hour over the phone at no more than $100 for the initial visit. After he removed the baseboard, cut the wall and diagnosed the problem, I paid $120 for the service. I didn't question it because I was extremely appreciative that he figured out the problem so quickly. I had every intent at that point to hire him not only to fix the water damage done and install a new shower door, but I also requested that he send me an estimate for new flooring on the ENTIRE top floor of my house. He is an alum from the university I graduated and currently work at. I really thought I was in good hands. He said he'll send me an estimate in a couple of days. On the following Monday (6/15) I followed up with an email to include a bid for a custom made door since I was expecting the estimate within a day or two. I heard nothing from Maurice all week. I sent a text AND email on Saturday June 20th at about 9 am and finally heard from him at 2:24 pm with an apology as well as an estimate. The estimate was a bit over my budget so after some dialogue via text messaging, I realize I need to prioritize the work and we both agreed installing the door and mold removal would be the priorities. He agreed to send me an adjusted estimate and schedule to begin the work on Monday June 22. I never hear from Maurice (granted Sunday was Father's Day). On Monday (6/22) at 11:46 am I sent a text AND email. Heard nothing. At 3:30 pm, I followed up with another text to schedule something since I had already cleared my calendar that day to get the work started. Heard nothing. Finally, I get an email with an adjusted estimate in which he doubled the cost for the mold removal. I felt extremely disrespected by Maurice. I lost the $120 I initially paid and have now inherited a hole in my bedroom wall. Again, if you're so busy, please don't accept additional jobs and show your lack of professionalism!"

Pacific Rim Cleaning and Restoration provides extensive water damage restoration for any and all possible scenarios. From full sewage cleanup in crawl spaces to hot water heater blow outs in mechanical rooms. Anytime water is not where it is supposed to be, call us and we can help. DBA Pacific Rim CR LLC

"Pacific Rim CR was extremely responsive when it came to mitigating water damage. They ran tests, removed flooring and dry wall that had been compromised, and dried us out quickly. However, they were not very professional or polite when it came to communicating with our insurance. They also offer reconstruction from the damage. Our experience with the reconstruction portion was terrible. The company was unresponsive for weeks and took months to provide a quote. We had told them twice that we only wanted the damaged area repaired, but they sent an inflated quote to repair the entire downstairs by ripping up all wood floors and replacing them along with drywall, base boards, and paint. They also were extremely dishonest and told us that they spoke with our insurance adjuster and got the inflated quote approved. When we told them we spoke to our adjuster and the quote was not approved as he was on holiday, they then changed their story to say the adjuster's supervisor approved. Again we spoke to our adjuster and this was not true. During this entire interaction, they continued to push us to reconstruct an entire downstairs of 1,500 sq. ft. when the damaged area was only 15 sq ft."

Mold Testing and Remediation questions, answered by experts

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.

In some cases, black stains on brick are caused by organic substances like algae and mold. However, it's more likely that the black spots you're noticing on your bricks come from carbon from vehicle exhaust or soot. Black stains can usually be removed by scrubbing the brick with a brush and masonry cleaner or power washing.

In most cases, it's not worth the risk of buying a home with mold. You should carefully weigh the pros and cons before making a decision—and there are far more drawbacks than benefits. For one, buying a house with mold opens you up to health risks since mold can cause respiratory and allergic reactions. If the mold is widespread throughout the home, the cost to completely remove it, make necessary repairs, and prevent it from returning is often not worth the cost savings of buying a mold-infested home for a bargain.

Both mildew and mold come from fungi. One of the main differences is that mildew’s texture is dry and powdery, whereas mold is fuzzy and slimy. In addition, mildew isn’t very thick, while mold looks three-dimensional. Also, mildew is typically light in color, whereas mold comes in various shades, including green and black.

Toxic black mold on wood appears as dark green or black patches. It often has a slimy or wet texture and may spread across the surface in a spotty pattern. The affected wood might appear discolored, soft, and damp. Identifying black mold early is crucial because it can cause severe health problems when its spores are released into the air. Prompt remediation is necessary to prevent further damage and health risks.
