"It went great. I got four quotes, they were the 2nd best price, but close enough to the best that I picked them because they do the work themselves and I'd been in touch with the owner Jose and I liked him. He was very involved, came over during the day to make sure everything was going well. I liked the workers, they were very polite, helpful, and very skilled and competent. I realized one small issue the next day (I wanted the bath spout moved), and they sent someone the next day to fix, no problem. Overall a great experience and I highly recommend."

"They recommended a good solution for the occasional shallow flooding in the garage (installing a sump pump) They started soon after we submitted the request and they did a good job. Most importantly, the pump kept the garage dry through our seemingly endless rains this winter. There are 2 reasons I rate the job with 4 stars rather than 5. (1) The job did not pass the city’s inspection and a critical connection had to be reconfigured (after which it passed) and (2) there was some weirdness around payment on the last day of the actual work (before the inspection) in which the crew seemed unwilling to leave without a check and then were slowly driving around the neighborhood afterwards. When I brought this up with my contact at the company, he denied that the van was theirs (which it definitely was) and didn’t really explain or defuse the bad feeling this created. But … they did a good job and in this day and age that’s really important and can’t be taken for granted. I recommend this company with the suggestion that paperwork, permitting, terms of payment etc should be clearly settled in advance."

Septic system installations and replacements FAQs

A septic tank typically lasts 15 to 20 years, depending on the materials used, maintenance frequency, and soil conditions. Regular inspections, proper pumping, and careful water usage can extend its lifespan. Professional maintenance ensures your system remains efficient and helps prevent premature failure.

Your septic tank should be pumped every three to five years. In fact, the recommended interval for pumping is every three to five years, as this schedule effectively prevents the buildup of solids and maintains the system's performance. Factors such as household size, water usage, and the capacity of the tank can influence this interval. Adhering to a regular pumping schedule minimizes risks of backups and system overload, ensuring efficient operation and longevity of your septic system.

Your septic system shows signs of failing when you detect noticeable odors and unusual moisture or overly green patches in your yard. In essence, clear indications such as unpleasant smells, gurgling noises from the plumbing, and areas of excessive vegetation or saturation signal that the system may be compromised. Additional symptoms include slow drainage and standing water near the drain field. These warning signs require immediate professional evaluation to prevent severe damage or environmental hazards.
