Excavation Contractors Portola Valley

I would highly recommend Geobear as they are very knowledgeable and honest! We had foundation cracks at our home, Gene provided us with great feedback to understand the cause and remedy. They went above and beyond for us, after studying the situation and giving their opinion, they helped us to choose another solution provider to fix the issue. Who does that in todays world. Most companies would lie just to get the job. Greatly appreciate all their help in honesty!

~ JW Haga

I am giving GeoBear (Gene) five stars because of their knowledge, professionalism and responsiveness, I didn’t have to wait weeks for an appointment unlike other companies to get a professional opinion an assessment of my house. Gene, was very methodical with his reading on the equipment that he brought, Gene took the time to educate us and explained why he doesn’t think that the house has any foundation issues, it is quite refreshing to have someone as knowledgeable and honest as Gene is. I would highly recommend any consern homeowner out there to contact Geobear for their house foundation questions. Thanks again Gene for taking the time and for your quick response and especially for giving us peace of mind!!

~ Carlos Ramirez

I am extremely grateful for the time and knowledge that Gene gave when coming to my home and assessing if I had foundational damage. He showed up on time, took detailed data and was able to share his expert knowledge. He was also so friendly and went out of his way to bring me peace of mind. I would highly recommend Geobear to anyone who has concerns about their home’s foundation.

~ Vikki Dunsmore

Brought our slab back up 1 1/4 inches. Definitely the least evasive way to fix a slab. Will definitely recommend if I ever get the opportunity.

~ Cody Woods

Recently, my house has a foundation/settlement problem and Geobear offered me their highly effective and cost-effecient geopolymer injection technique that fixed the issue. Traditional methods will take weeks using highly labor intensive procedures to tackle the same problem. Geopolymer is a new science that works well. If you have encountered the same problem like me, I highly recommend you to talk with Gene and his team. You will get honest and expert opinions from them, and most importantly, it will save you tons of time, money and energy.

~ DPW

We bought our house in December and we knew it had foundation issues. The traditional method of repairing our issue was extremely costly. We looked around for different quotes and it was a scary experience. When we stumbled across Geobear, we were pleasantly surprised with their professionalism and transparency. I am very satisfied with Gene’s (president of the company) open communication and availability for questions. The process took 3 days and we couldn’t be more happy with the experience.

~ Grant Tinnes

Geobear was a fantastic partner and provider in working to stabilize our home/foundation. Can’t recommend them enough. We unfortunately had what many homeowners hope to never have, foundation issues. We noticed a couple new drywall cracks. We looked at a lot of different options and we were overwhelmed with the price for many. In google searching and reading up on different methods, I discovered Geobear as an alternative to helical piers. They’re relatively new in the residential space here, but are the more “standard” solution in the EU & UK. That gave me peace of mind. We even found another issue as part of the prep for the project which was not something they could remedy, but they were super helpful with their own time of helping me kind figure out what was happening. Great customer service.

Alex and his proficient team successfully removed and excavated the septic tank, ensuring a thorough cleanup. Their expertise and knowledge make them highly recommended for any excavation projects. I wholeheartedly endorse them for their outstanding workmanship and professionalism.

A fantastic company with a thoughtful owner provided detailed written and verbal explanations for their high-quality work, including driveway pavement, backyard cleanup, and obtaining necessary permits. Their excellent service at a reasonable price ensures I'll hire them again. Many thanks to Alexis for their great work and thoughtfulness.

~ Chao F.

For top-notch pool removal services, Alexis and his team are unmatched. Their professionalism, meticulousness, and high-quality work make them the ideal choice. Alexis is well-versed in city requirements and permits, ensuring compliance. Despite unexpected storms, the team efficiently protected the pool area and restored it afterwards. Highly recommend their exceptional work.

~ Sunny L.

My realtor recommended an inspection of the sewer line before purchasing my home. There were some issues with the sewer and Abraham came out more than once to complete the inspection as there were two accesses (one was hidden). This impressed my realtor (not easy) so I hired them to replace an old line. They did an excellent job and showed up and finished on time and charged exactly what the estimate was.

~ Jennifer McDonald

They were timely and friendly.

~ Susan Evans

Great job on time feedback solid work

~ Piper Cory

Abraham and his team did an amazing job for us. They started the job right away. 2 days in the job is completed. Abraham is very professional and nice person. Good Job!

~ Linda Delfino

Abraham and his team did a great job with our plumbing when we bought our new home, and Abraham recently came to the rescue to help with an unrelated leak. He is always professional, friendly, and helpful.

~ Rachel Ray

I always use US Trenchless. They get the work done a really good company!

~ Angel Dimitropoulos

I would highly recommend US Trenchless. I called on Wednesday, May 1st, and Abraham had two awesome guys, Carlos and Wyatt, at my house at 8:30 on Thursday morning. They had to dig and trench so much that they needed to come back on Friday to finish. Not only did they do an amazing job repairing the issue, but they did an amazing job cleaning up after they finished the job.

~ charlotte Renovich

Great and professional

~ marissa vigil

Abraham was incredibly responsive- quick to answer text messages and pick up the phone. They gave a true and accurate estimate for work that was needed. They delivered on everything that they promised.

~ Judy R.

Abraham did a sewer inspection at a house we were buying, and we ended up working with them on a trenchless sewer line replacement and also underground drainage lines. They were not the lowest bid, but the crew dug by hand with shovels (no trenching machine or excavator), so they were able to be careful of other underground stuff. They also hand compacted and leveled the soil afterwards.

~ Dave Parker

Abraham did a great job. He presented us with a very fair estimate and explained the work that was going to be done in great detail. He was here every day the job was going on. We had 70 year old water and sewer lines replaced and a new clean out installed near the house. Carlos and Wyatt were very careful in digging the holes and took great care to protect the remaining pavers and brick. After both the water and sewer lines were pulled they did a great job putting everything back. You’d never know that anyone was there. I would highly recommend them!

~ Randall Wheless

Quick and easy process! Thanks!

~ Alexandros (Alex)

My go to for sewer inspections and repairs! The owner is great to work with! I appreciate their website and how easy it is to order inspections. Reports and estimates have been clear and fair.

~ Jamie Martin

Excellent abf fast service! They were able to get me in a week earlier than expected too!

~ Deanna Montgomery

As a Realtor, I rely on the expert opinion of the vendors who do my inspections. Not only are the inspections detailed and easy to understand, US Trenchless has the highest standards of their employees. I have had the pleasure of working with Abraham on several occasions. He is polite, detailed in his inspection, knowledgeable and has the greatest customer service in the industy. In addtion to Abraham, the whole staff is friendly and easy to do business with. From the moment of the receptionist answering the phone to the delivery of a quality inspection - I recommend US Trenchless.

~ Matthew Phelan

Abraham gave me the best quote. They finished in 3 days with inspection. This was one of my smoothest jobs. They replaced an orangeburg drain from the building to the city. It kept on clogging so I finally decided to replace it. They also helped me contact the city to follow up with the city's drain,.

~ Tuan Tran

US Trenchless was the best value among the three estimates obtained. The cost estimate was the amount paid. They completed the work on time, passed inspection, and exceeded expectations.

~ Eduardo

Good company to deal with. I would use them again.

~ chris

They did a great job at one of our Roseville rental properties replacing the sewer line. Abraham was very professional and courteous and finished the job in 2 days while we were on vacation! Great price for a great job!!

~ Pat Shearer

US Trenchless did a great job and made the overall process of scheduling, inspecting and reporting on condition of our sewer line easy. Thank you Shannon in the office and Abraham for your assistance and service. Top notch!

~ Jim Brenner (JB)

Abraham came for a free estimate, was very professional and gave me some useful information. It turns out I didn’t need their service. As a senior, I very much appreciated his service.

~ Sherry Wynne

I have used US Trenchless's services on more than one occasion for different properties. The reason I continue to use their services is their professionalism, honesty and integrity. They explain everything to you, provide a report and video so you can see what they are explaining. When calling with any sort of questions, they help you immediately, and are very friendly.

~ Nicole Chuck

Abraham and all crew involved including Francisco and Wyatt were very professional and went above and beyond in helping us with our new home. From inspections to repairs their work is quality and they back up what they do. They even came back to check on and help us with repairs that they were not directly responsible for. Abraham is very kind and personable and helped us through everything we needed in a very timely manner. If their work costs more than others, it is very much worth it and the warranty they put on their work can let anyone feel at ease for choosing this company, they will stand by what they do.

~ Justin Johnson

Abraham from US trenchless is a very personal and professional person who took great care in explaining everything about my sewer line. I would recommend Abraham to anyone who has a need to check their sewer lines! Thank you so much in sending Abraham to my home US Trenchless!!

~ ken souza

Abraham and his crew saved us thousands of dollars! We were quoted $30k+ for work another plumbing company deemed "urgent". Abraham came out and was honest and transparent throughout the entire process. He took the time to explain what was actually needed for our recently purchased home. It took the crew 2 days to replace some old cast iron pipes in our front yard for a fraction of what the other plumbing company tried to squeeze out of us!

~ Jesus Ferreyra

Five star quality. Professional and unmatched knowledge and experience. Did the work in one day where it would take most plumbers a week to do. Unbeatable pricing and very workable. They definitely listen and deliver exactly what was needed and asked for.

~ Jocelyn Chang

It's great to find a company that knows their craft and also provides amazing customer service. You won't be disappointed. Abraham is great!

These guys were great! They did an excellent job of replacing my sewer line — explaining the process to me and finding the best, most cost-effective solution for the job. They even went above and beyond by offering to fix a leaky faucet by my front porch! I will definitely be calling them again for any other issues in the future. Thank you, Abraham, Francisco and Carlos!

~ Deb Bowyer

Got a sewer inspection. Professional and timely.

~ Kirsten B

Happy with services so far with UTI, the technician was there on-time, courteous and explained me everything. Now I have few fixes that were recommended by them so will be revesting this review when they are done.

~ Sandeep Sharma

Had them come out to preform an inspection on the sewage system of the house I’m purchasing. Found some issues that we will bring to the attention of the seller. Was able to schedule quickly. They provided me a video of the inside of the sewage system.

~ Tyler Crews

I called several trenchless companies but they did not do gas lines. US trenchless does so they came out and gave an estimate. The price was high but we needed to get the line replaced. They completed the job in two days as was quoted. Great quality work and they cleaned up really well. Nice to have the work done without digging up the concrete!

~ Paula Mendenhall

I wanted a second opinion on a recommendation and I reached out to US Trenchless. Abraham was great. I appreciate the professionalism and knowledgeable advice he offered.

~ Drew Hart

I have used US Trenchless to do several sewer inspections and they have done a great job! Their online scheduling is easy. They are punctual and always do what they say that they will do. I would and do highly recommend US Trenchless!

~ Patricia Hendricksen

Awesome camera sewer pipe inspection!

~ Nicholas Labedzki

U.S. Trenchless installed a sewer cleanout in my front yard and did a fantastic job. An employee named Abraham arrived on time and completed the job in under two hours. He was extremely respectful of my property. After digging the necessary hole for the cleanout, he went to great lengths to repair the grass/landscaping that was impacted. Once he was finished, he explained the work and offered to answer any of my questions. It was a fantastic experience, and I will be using US Trenchless in the future.

~ John Powell

Responded same day. Gave me all the options for water heaters. Installed water heater when they said they would. Did a great job. Will work with US Trenchless whenever I need plumbing issues.

~ Glenn Belden

Very professional, and a job well done. Great response from owner during the project and after.

~ Petti Woo

I needed new outdoor lines from my home to the sewer. The lines were old and ran under an old kennel and a partially cemented yard plus a huge distance. I also had a tenant moving in very soon, so getting it done well and fast was imperative. Abraham was understanding, efficient and answered all my calls promptly. They stayed on schedule except for a one day delay due to county inspection a day late. Since they started so quickly from my initial call one day was before my tenant arrived…but just by a day. It hasn’t been long since the work was done so I can’t speak to that but I do feel comfortable that if any problems arise, though I don’t expect they will, US Trenchless will address them. They were a good value, efficient, on time, response and I would recommend them unconditionally.

~ Susan Leith

The perfect pros!

~ Maggie Janett

Nothing but Professional!!! I had a few ideas in my head, and ACI and their team was able to transform my home into exactly what I wanted, On time and under budget! Now that's amazing! I would recommend to all my friends and family and anyone that wants a job well done!

~ Sinem V.

ACI was great to work with. I would recommend them for anyone looking for a general contractor that is quick, responsible and fair priced for their services.

~ Matthew S.

These guys are really great and have really nice guys working for them. When they say they guarantee their work, they aren't lying. Would recommend these guys to anyone who needs work done.

During my years working with Earth Tech Drilling, I can always count on them to be prepared and complete the job in an efficient and timely manner. They use well-maintained equipment in order to maintain high levels of productivity. Easy to coordinate and schedule work. Great company and well trained and experienced staff.

~ Andrea Suarez-AbastidaAECOM

I have been in the environmental assessment/cleanup industry since 1987, including 5 years managing a Florida environmental drilling firm, and I am impressed with work product and professional nature of the folks that work for Earth Tech Drilling.
