"I had an emergency situation. The main waterline to the house was blocked. I called Chris around 8:30 AM and he responded straight away.. he assessed the situation, took care of permits and completed the work by mid afternoon. We have water restored, and a huge blockage removed from our main waterline. He was very professional, courteous, I would highly recommend this company."

"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

New or Failing System we perform perk and have Design Engineers we work with your particular project. Demolition of any Building and removal of debris. We do not perform septic pump outs.

"Septic tanks were left exposed, site was a mess, and vent pipe was not at the required height. We talked with him a month before we anticipated water connection, so he knew our timelines. We attempted to contact him every day for a week to schedule final inspection after water was connected, but got no response. It took two emails from the city for him to sign the certificate of compliance."

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.
