Albert Nahman Services was founded in 1981 and has been serving Berkeley, CA and it surrounding areas in all their plumbing and HVAC needs. Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

Thank you for choosing H K & S Plumbing Co.! We are committed to providing quality workmanship and superior customer service to all of our existing, and future, clients. We strive to maintain our reputation as a high quality, service oriented company. No job is too big or too small. Call today!

"We had broken underground pipes that flooded ours and attached neighbors houses. We have a shared meter, with neighbors having their own shutoff, we did not. After 3 quotes, we felt most confident in Harry. He installed a shutoff valve for us, and now neighbors and us are not dependent on each other’s water. He then isolated and replaced the damaged pipes. He was able to do this without further damage to the house. He came in less than verbal quote and never tried to upsell, which was an issue with one of the other companies. We are very happy with Harry’s work, would highly recommend him."

Percolation Tests questions, answered by experts

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. 

Asbestos was most commonly produced and integrated into building products from the 1920s to the late 1980s. In reality, asbestos use should have ceased much sooner because asbestos was linked to cancer in studies produced as early as the 1950s. You can even extend that number past the 1980s due to stockpiled materials and because some countries treat asbestos use differently. It may also be found more in commercial applications than residential.

The presence of asbestos fibers in siding is a critical health concern, as they can be inhaled and lead to severe respiratory issues. Even if asbestos siding appears to be in good condition, it may become a danger if it deteriorates over time or is disturbed during a renovation project, as this can release airborne fibers. Exposure to these fibers is linked to life-threatening diseases like asbestosis, mesothelioma, and lung cancer.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.
