"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"These people are competent but their ethics are highly questionable. I posted a job description on yelp and tendered offers from many plumbers John's Plumbing replied and agreed to do the work for a specified price. The work consisted of two parts. After they had done the first, they told me it was best to wait until the bathroom wall was tiled before doing the second and assured me they would return. After tiling was complete and I requested they come and finish the work they surprisingly told me it would cost another $500. Miscommunications can of course occur but in this case the scope of work was given to them in detail and clearly included both parts. This is not only highly unprofessional but outright dishonest. While they may be competent I would advise people to consider choosing another company for their plumbing needs that has a higher ethical standard."

I am the homeowners caretaker and son, over 2yrs ago these SCAMMERS took $14000 from my dad to fix a clogged toilet ! ! ! I just found this out. They saw an easy target and ripped my dad off. Instead of snaking and pitting a camera down the toilet, they tore up the front yard. THEY DIDNT REPLACE ANYTHING ! They removed 1 of 2 Darin pipes. IDK why. THE IDIOTS also cut the discharge pipe for the pool [Expletive removed] U MORONS ! They then found a WATER LEAK under the driveway. WHY ARE YOU LOOkiNG FOR A WATER LEAK ! We wanted a toilet unclogged. The workers were [Expletive removed] and didn't even check to see if the clogg was fixed. BEWARE THEY SCAM THE ELDERLY ! ! The toilet never worked after all that. The other toilet is upstairs and is hard for my elderly parents to use. These guys are thrives, everyone contact them and ask why they treat our seniors like this.

"Very well. Ron, the technician arrived promptly. He did say that he may not be able to solve the problem on his home because the drain pipe was bigger than what he was equipped for, but he ended up managing with the smaller machine that he had. Next time, I would recommend verifying the pipe size with the client beforehand, but no harm done and problem solved! The company was very professional and efficient."

Percolation Tests questions, answered by experts

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

Asbestos siding is harmful as it can produce fibers that, once inhaled into your respiratory system, may cause mesothelioma, other lung cancers, and a dangerous scarring of the lung tissue called asbestosis. You can contain the siding within a series of barriers, but it is our recommendation that you hire a professional to remove any asbestos in your house. Its presence can permanently alter your health and the value of your property by as much as 10% or more.

Since DIY asbestos removal isn’t the best option to save money, there are other steps that you can take to help cut costs when dealing with this project. After speaking with your asbestos removal expert, discuss if encapsulation is an option. If it is, you can save between 15% to 25% on overall project costs over demolition and disposal. In addition, when speaking with your professional, discuss if there are any tax credits available for your removal project. Finally, check with your homeowner’s insurance to see if any removal costs might be covered. However, be aware that this is usually only applicable if the asbestos is due to a covered incident, like a tree falling into your roof.  

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. 

Because of the danger of inhaling asbestos fibers, figuring out through testing whether your popcorn ceiling contains asbestos is definitely worth it. If the popcorn ceiling texture has asbestos, remove it as soon as possible to keep your family safe. Any home built in or before the 1980s that has popcorn ceilings could have asbestos, necessitating testing. Asbestos carries several health risks for people who inhale it, including the increased chance of developing lung cancer in the future.
