I owe a special thanks to Martin & Daniel for doing a thorough inspection of plumbing work done by a fraudulent company! They assured me the work was done properly & water leak was fixed. Martin completed other tests that showed no water leaks! I will definitely call Plumbing Plus in...

Was here when promised. Listened intently to problem and verified information. Went right to work on fixing. I have 6 valves and knew which one was the "problem one," tested, retested, and we gave it a try. Water came out first try. Made a couple quick trips to check and another test for wire...

The contractor said he would find a plumber to do the test and the repair on the toilet and the drain as well as replace all the angle stops at a reasonable price (which later I found out the quote was not that reasonable). He never returned my calls for the job.

The first go-around was not productive. The rep lost professional creditability when he couldn't find a leak that would justify 3 times the water usage. I called back in a few days, and the assistant on the phones was really understanding, helpful, knowledgeable, and a really committed problem...

Went very well. They were very informative when I called them. We have small guest house that we wanted tested. The guy who came out was very polite and took care of business. Just like they promised, they had the results back to me in two days. I would recommend them to anyone.

I needed anti siphon valves replaced. The tech came in on time for an estimate. Based on the estimate I decided to just have them repair the valves rather than replacing them altogether. So he opened up the valve tops and replaced gaskets. After that they tested with water running and the leak...

Percolation Tests questions, answered by experts

Knob and tube wiring is an older type of electrical wiring that's no longer used and generally not considered safe. However, some homes still have it, or may have a knob and tube wiring system that was incorrectly modified or rigged to work with a modern electrical system. Knob and tube wiring may contain asbestos insulation, but the only way to know is to have the material professionally tested.

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

If you have an older electrical system with fraying wires and other signs of damage, removal may be the best course of action. When asbestos begins to break down, it's more likely to become airborne, increasing the risk of health issues when it's inhaled.

However, if the system is in good condition and doesn't have visible signs of wear or damage, leaving it alone may be the safest course of action. An asbestos abatement and removal professional can help you determine the best way to proceed.

When learning how to test for asbestos in a popcorn ceiling, you have an option for a DIY job or to hire a professional tester. You can purchase a kit at a hardware store and use personal protective equipment while doing the test. If you don’t want to risk any potential exposure to asbestos, hire a professional asbestos testing company instead.

Homes built before the 1990s may contain asbestos, but the only way to be sure is to have your home tested. Hire an asbestos testing and removal service to determine whether you have the hazardous material in your home and the best process for removing or sealing it.
