"Our landscaping in Menlo Park needed a complete refresh. The team replaced thirsty plants with drought-tolerant options that still provide plenty of color and curb appeal. We're using much less water without sacrificing appearance."

"Mike was called to clear an untimely (let alone super nasty) clog and backup in my home's sewer system around 11:30 PM on a Saturday night. It was a stormy night and he was out quickly to take care of the clearing of the (yuk) debris and digging out of a secondary driveway drain that was filled with other debris left by a construction crew doing some work on my driveway. Mike cleared out the drain area and the overflow area too. 5 stars all the way!!"

Septic Tanks questions, answered by experts

It is not normal to smell your septic outside and indicates a problem such as an unsealed manhole or access lid, a clogged septic line, a faulty vent stack, or the need for a septic tank pumping. If sewage is leaking from your septic system, it can be hazardous to you, your family, pets, and the surrounding environment. You can troubleshoot the issue yourself, or contact a septic tank pro who can resolve the issue quickly.

The bacteria already present in your septic system should be enough to break down solids in a properly maintained septic tank. However, if you’re in a DIY mood, you can try adding (well-mashed) rotten tomatoes to help the good bacteria fulfill their duty. Just make sure you give them a couple hours to work after flushing them down.

Ensuring you have adequate space for your engineered septic system is crucial. You’ll need to reserve approximately 900 square feet for a three-bedroom home’s system. However, the type of soil you have, soil absorption rate, the size of your home, climate, and local zoning code will impact the actual amount of space you need.

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product. 

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.
