Recommended Customer Reviews

Terra Nova Engineering is a 5-Star Business!!!! Sheila replaced and certified our sewer lateral in Richmond without a hitch. We live out of state and were overwhelmingly impressed with Terra Nova's quick response, competitive price(including City fees) and professionalism. Bonus: locally owned business. Highly recommend!!!

Terra Nova is a well run engineering and sewer construction company. They designed and implemented TWO sewer laterals for me. They beat the quotes from other companies. One job was over 30 feet long and relatively complicated, and they did it well. Even with unexpected problems coming up, they didn't increase the price.
They also understand city rules, permits and regulations. They even called me months later to remind me to get my city credit refund check!
If you have to fix or upgrade your sewer lateral in the Bay Area, just call these guys - they are the best in the business!

I Highly Recommend Terra Nova Engineering!
Superb Service - Shelia was very helpful with excellent knowledge and a Great Attitude.

I received an estimate from Terra Nova for a sewer lateral replacement in Berkeley. I ended up going with another company because I also wanted to get some other plumbing done, but I wanted to leave a positive review because I had a great experience with them.
Sheila was responsive, nice, and clearly knew her way around Berkeley's regulations and compliance requirements.
The estimate was detailed and informative, and the quoted price was very competitive. They also do free estimates, which should be standard for uncomplicated sewer laterals. Beware the places that charge $150+ for a camera inspection just to get an estimate.
If you need a sewer lateral replacement in the East Bay, Terra Nova should be on your short list.

Needed to replace my sewer lateral. I went with Terra Nova because
1) Excellent communication
2) Very competitive bid
3) Local to my city
Am very happy I did so. The work was completed quickly, on-time, with no damage to surroundings. All area was left clean. Highly recommend.

They did a great job on my trenchless sewer lateral replacement. Very low price excellent service. I am leaving this review because I stumbled on this when I was looking for the phone number to give it to a coworker who needs his lateral replaced. Sheila and Mirko do great work and are a pleasure to work with.

Awesome company, awesome service! Terra Nova communicated well with me, and replaced the sewer lateral beautifully and the asphalt on the street (a steep grade) looks superior to my neighbor across the street who went with a cheaper company and had to have the work done twice!
I recommend them highly!

Sheila and her team recently completed a sewer lateral replacement at my property in Richmond. Sheila has excellent knowledge on underground utility repair. She responded to all my inquires professionally and in a timely manner. She provided all the information I needed for claiming a city-owned tree damaged case. Her fees for the job was adequate and worth for the quality of service.
One thing I especially want to endorse was their professionalism in working in a difficult environment. Unfortunately, I have a hostile neighbor complaining about the job; he was harassing the team and even called the police in trying to stop the job. However, it was not a problem because the team had the city permit in place. The construction staff was not discouraged by the harassment, and dealt with it in a professional way. They continued the work under safety and completed on time, and to satisfactory.
I highly recommend this business if you are looking for a qualified contractor to resolve plumbing issues in the Richmond area.

I met the owners of Terra Nova Engineering, Sheila and Mirko, in May of 2007 at my open house. The sellers of this Richmond Annex duplex had already hired them to do their sewer lateral work. My sellers researched all the geographically desirable companies and were very happy with their work and the price. I had to try them myself. They exceeded my expectations!! I had been using several other companies for the previous 20 years and had no idea what customer service was all about until I worked with Sheila and Mirko. They are very professional. They are also very connected with the officials of the local municipalities which cuts through all the red tape, respectful, competitive with their pricing, punctual, organized, hold my clients hands through the process of getting their bond money and offer a senior citizen discount. Their crew is friendly and approachable. I recommend them to all my clients. What can I say? They are the BEST OF THE BEST!

Terra Nova Engineering just completed a sewer lateral replacement at my home in Oakland. We knew the lateral wasn't compliant when we purchased the home back in December. We had 5 different contractors/plumbing companies come out and give us bids. We were referred to Terra Nova by a neighbor who had them perform sewer lateral work a few years ago and were very satisfied with their work. Together with a competitive bid and our neighbor's referral we chose to go ahead with Terra Nova. Great communication before, during, and after the job as Sheila confirmed start date and provided updates via email and phone during the work. Our job was far from a normal scope of work as our main line connection was 13 ft deep in our backyard. Mirko and his crew worked for 16 hours the first day to ensure that we would have our sewer hooked back up that same day. They finished the job about halfway through the second day. Very polite non-smoking crew who also did a great job restoring our backyard to it's pre-construction state.
Would definitely recommend using Mirko, Sheila and the team at Terra Nova Engineering for your sewer lateral compliance needs.
