"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."

"Ybarra Professional Builders did 2 big plumbing projects on my house and property. Not only did they install a brand-new main water line to replace the old leaking galvanized steel pipe, but they also re-piped my house's plumbing as it was also made from that same rusting out galvanized steel. I also had some other major work done by them at the same time (tree removal and sprinkler repair) but since Home Advisor asked for a specific type of project for this review, I will only review the plumbing projects. Vlad was the project manager for all of these projects. He coordinated all of the sub-contractors' work and got the projects done in a timely manner. There were none of the time issues that I had heard about with other contractors, such as waiting weeks between one phase of a project to get the next one started-after one phase was done, the next phase would begin with no more than a day or two in between. He was very pleasant and very patient with my many questions and concerns and kept me up-to-date with what was happening. The project that I most dreaded, the house plumbing re-piping, was not as bad as I thought it would be, to my great relief. All of the people who I dealt with at Ybarra were pleasant and professional, from the sub-contractors to the office staff. I think the quality of the work performed was very good. In the additional clean-up phase, the holes in the drywall where the plumbing had been re-piped were patched and painted, and the concrete where the driveway had to be cut to replace the main water line was re-poured. This portion of the project was available as an additional cost, but the workmanship was very good. I had heard and read many horror stories about dealing with contractors so working with this group was a pleasant surprise. Thank you, Vlad."

"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 FAQs, answered by experts

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.

The ideal depth of a septic drain field is 18 to 36 inches below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.

If your well pump is running continuously (meaning without turning off or stopping), it's a sign that your well pump is starting to break down. The length of time your well pump should cycle is dependent on many factors, like the tank size, pressure setting, and even the amount of water in your well. Generally, your well pump should cycle, or go from running to not running every few minutes.
