"We were out of town when we had a plumbing leak at our rental property. I contacted Aurelio and he diagnosed the problem, had to go to Home Depot and purchase a new faucet for us and quickly installed it. He was courteous and communicated all along the way. I definitely would use Aurelio again and highly recommend him."

"I was very pleased with this project from beginning to the end. The project took a couple days as expected. The crew was friendly yet professional. Ozzie and Felix took the time to explain and answer any questions I had. They bent over backwards to make everything right. Im so happy with the finished product, would definitely recommend Jacuzzi for bath remodel."

"Tech was able to tell me what the error code meant but did not want me to order part until testing with volt meter. Diag appointment with volt meter did not cost extra. Tech gave me part numbers and it fixed the problem."

"Perez Plumbing installed a new faucet in my mom‘s kitchen sink. The work was done perfectly in a timely manner and Jesus. The owner took the time to do some extra things that weren’t even in the contract. I highly recommend this Contractor."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

Percolation Tests questions, answered by experts

Professional testing is advisable to ensure safety regulations are met, and accurate results are obtained using certified methods.

While asbestos can’t be directly absorbed through the skin—the fibers are too big—skin contact can still produce symptoms. Contact dermatitis can flare up in sensitive individuals but in most cases, the danger from asbestos comes from inhaling the fibers, or dust, that is produced when asbestos is disturbed. If you touch asbestos by accident, immediately wash yourself and your clothes.

Testing is crucial to identify harmful asbestos fibers common in building materials from older properties, ensuring safe environments and health.

Unlike some home problems, such as water damage or pest infestations, asbestos can be very difficult to spot. Asbestos is a mineral in the form of microscopic fibers and was previously used in building materials for its bonding and fireproofing abilities. Insulation, roof shingles, ceiling tiles, floor tiles, pipe wrappings, soundproofing materials, and textured paint features like popcorn ceilings are common sources of asbestos, particularly in homes built before 1980.

Age is perhaps the biggest indicator of asbestos, as legislation passed in the 1970s labeled asbestos as dangerous and regulated its use in building materials. Signs of age in the form of wear and tear or material degradation are also indicators that asbestos fibers may be leaking into the air, but ultimately, it’s difficult to detect with the naked eye. If you have reason to suspect asbestos in your home, it’s best to hire a certified asbestos inspector.

Unfortunately, home inspections do not check for asbestos because of the liability factor involved. That’s why you should hire a trained professional with specialized equipment to test for it. 

They will inspect all areas of the home and take samples of various materials to test. Opting for an asbestos inspection can prevent the risk of exposure to this hazardous material and save on costly repairs that may be required.
