Mr. Gonzales replaced my 2 rainbird sprinklers in my garden. He tested them to my satisfaction so the spray range was very accurate. Mr. Gonzales did a great job.

He arrived on time; with all his equipment in good working order. His testing for mold was through and the lab responded quickly. I would have appreciated a bit more explanation of the report I received but the money was well spent.

Percolation Tests FAQs, answered by experts

No, an N95 mask will not protect against asbestos and many other hazardous materials, such as carbon monoxide, gas, chemical vapors, and other gases. You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, hire an asbestos abatement professional immediately and avoid the area until they arrive for the inspection.

Regulations require certified professionals for removals and disposal in compliance with local and federal guidelines, ensuring safety and legality.

Asbestos is absolutely cancerous. In fact, around 4% of all lung cancer cases are the result of asbestos exposure. This is why we recommend a full, professional removal and cleaning of any asbestos found in your home. If you are unsure whether there is any present, you should call a pro who will inspect your property.

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

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.
