"Our potfiller kitchen faucet began to leak at the wall. Great reviews on Yelp and Nextdoor prompted us to contact Plumbtree Plumbing. Their online appointment facility was very easy to use; an appointment was secured for the same afternoon. A very professional, courteous, and personable plumber, Bruce, diagnosed the problem and made an expert repair for a reasonable cost. We were very pleased. Bruce was genuinely concerned about our home's plumbing. Without any sales pressure at all, he and his equally expert associate, Matthew, made an inspection of our water pipes and discovered three issues: 1) the "water shutoff valve" at the base of the house was actually a gas shutoff valve!, and 2) a number of our water pipes were galvanized pipe instead of the desired/required copper pipe. While under the house, Matthew spotted issue # 3) and photographed it: one of our heating ducts had become disconnected, thus pumping hot air into the crawlspace! So, we are having Plumbtree Pumping come back to make a thorough estimate to correct items 1) and 2). (And our HVAC people will fix item 3)!) Please strongly consider using Plumbtree Plumbing for all your plumbing needs!"

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."

TJ's Plumbing has been in business for over 10 years we specialize in residential and commercial Plumbing systems. We pride ourselves on the quality work we provide, while delivering great customer service! Call -or- click to schedule your estimate today!

"Though I am happy with the final result, I feel that TJ did a bit of a bait and switch. The person who showed up, Felipe, was from a different company. "TJ" quoted me $900 for the job and $300 to move washer and dryer to access the main valves. That's $1,200. In the end, washer and dryer were not moved. But I did ask them to replace a faucet cartridge in my bathtub, which they did. But before that, Felipe had managed to turn off the water to my unit without moving washer and dryer. He then had to cut into drywall to locate the outbound pipes, but made a mistake. The next cut he made found the water pipes but these were the wrong pipes. An emergency water shutoff to the building was required. In the end, the bill was for $1,800. They did not take credit card. No receipt was given to itemize work done. These guys, from Moor Plumbing Solutions, did work hard and got the job done but there was a serious lack of transparency from the very beginning, not to mention a near disaster."

Percolation Tests questions, answered by experts

Since the EPA partially banned asbestos use in 1989, it is not commonly used in siding in the United States. Many other countries, such as Iceland, Canada, and Denmark, also have bans on asbestos. However, asbestos siding is still present in homes built before the late 1980s. Remember, the only surefire way to know if your home or siding contains asbestos is to have it lab-tested by a professional. 

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 microscopic asbestos fibers do not cause eye irritation, throat irritation, or lung irritation. If you are inhaling fibers, you will not know it. This lack of immediate symptoms is one of the reasons why asbestos is so dangerous. You cannot know for certain if you are inhaling fibers, which is why you must wear safety gear if you could have any chance of an exposure while working.

Asbestos can be found in many building materials, especially if the materials were installed more than 20 years ago. Asbestos-containing materials (ACM) can include:

  • Acoustic ceiling tiles

  • Furnace insulation

  • Home appliances

  • Fire-retardant clothing

  • Cement pipe

  • Pipe insulation

  • Wall and ceiling insulation

  • Vehicle brake pads

  • Vinyl flooring

  • Sprayed acoustic ceilings

  • Stove insulation

  • Patching compounds

  • Textured paints

  • Roofing shingles

  • Siding

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.
