Horrible experience Glosage Engineering was contracted by the local sewer district to replace the main sewer line (not the lateral), trenchless. There is a utility easement along the property line, so no problem giving them access. They gave us a description of what they are going to do, and that seemed fine. However, reality looked much different. First they placed the line further into our property than planned. Then they excavated a huge hole, digging plants out and cutting irrigation lines. Next they decided to actually pull the new line across our entire property, damaging more plants and ripping out sprinkler heads and rocks embedded in the slope to prevent soil erosion. I pointed all these things out to Glosage's foreman and they promised to take care of it. Nope. They filled the hole, haphazardly put the tree back in the ground (not even streight) and just took off. I called them and the sewer district, nothing ever came out of it. The sewer district admitted that they had issues with that contractor and many complaints. I ended up spending a couple of hours and some spare parts from Home Depot to put things back in order. So my gentle advice: Be very careful with these guys! read more

Hands down one of the best 'plumbing' experiences I've ever had. Luis and his crew could not have been more polite, professional and efficient. They did what they said they would do and overcame any obstacle that arose without any complaint. The quote was 100% accurate, even though they incurred more cost than they originally thought. They completed the job on time and on budget which is rare in my experience as a home owner. It truly was a pleasure dealing with them and I wouldn't hesitate to recommend them to any of my friends and family. I had bids that were twice what Luis quoted, from 'supposedly' reputable local plumbing firms - for the same job. read more

If I could give zero stars I would. PLEASE BEWARE!!!!!!!! My clients purchased a house where Glosage did the bid for the sewer later bid. Well, he did a bid alright... for the wrong house. Glosage actual bid for my client's house ended up being twice the amount of his original bid. He admitted he made the mistake but was not willing to work with my clients on his bid.... So not only did he not care that he made a mistake but he still insisted on making a profit. Someone said he is a man of his word. He is not a man of his word he is only out for himself and runs a shady business. I am making sure everyone in the real estate community knows about this as I do not want another client to have to have this same experience. read more

This is a very late review . Glosage Engineering did an excellent job ! Luis and his team was very professional and fixed our sewer lateral drain with no problems. Their price was excellent, compared to others in Marin County . Luis was very communicative and explained everything, step-by-step! They had to dig all the way out to the street, He coordinated all his men, also directed traffic. They were very careful not to destroy our plants in the garden. He is very experienced and definitely knows what he's doing. We will hire him again if we have another complicated plumbing problem! read more

Luis and his crew did a great job at a great price. He knows his stuff and takes pride in his work. I recommend him to everyone. When I needed my sewer lateral line updated I got bids from a few places on Yelp with 5 star reviews. Just when I was ready to sign with one of them, a neighbor sent Luis to my house to ask if he could bid. I wasn't sure since I hadn't seen him on Yelpl. But he explained that he's been doing this work since 1999 and started his own company in 2016. Plus he's bonded, insured and licensed, so I let him bid. The other companies' bids had a clause that if they ran into problems the price might go up. But Luis said the job seemed straight forward and even if problems came up the price wouldn't change. So I hired him and I'm really glad I did. Here are some reasons why: 1) He kept me informed all week about the status of getting permits and utility companies coming out to mark off utility lines. 2) On the morning of the job he walked me around the work spots and explained all the steps of the project. Luis stayed on site and worked with his crew. 3) He took extra care to find where my sewer line crossed the water-main in the street and went very slowly and carefully so as not to damage it. When a neighbor had his line done a few years ago the contractor wasn't careful and broke the water-main, flooding the street and causing the block to be out of water half a day. 4) Luis encouraged me to inspect the work at every step. He and his crew really take pride in their work. They put my yard and the street back like they were before the work. Perfect. 5) Luis was always smiling and wonderful to work with and everyone on his crew were nice. It was a great experience. You can't help but want to give these guys 5 stars. read more

See all

First let me start off by saying that dealing with contractors that replaces sewer laterals is a big headache. I literally met with like 5 different contractors and all their quotes were way above my budget. I ran into Luis & Glosage Engineering by pure faith in my opinion. After meeting with him and going over his proposal, which was very competitive among 3 other big companies, we decided to close the deal and start working right away. Luis could not have made this experience any more easier, he always kept me in the loop of what was going to happen next. (City permits, city markings, and scheduling). Each guy on Luis's crew were young motivated guys ready to work. Everyone had a task to do, it actually made me feel I got more quality service than I had paid for (which is a plus for me the customer). And best of all, they started early, and finished early before traffic rushed in. Thank you Luis & Crew, much appreciate it. Overall; Competitive in pricing, honest, and man of his word. read more

I don't normally write reviews but these guys deserve it! I remodel and renovate several houses a year and do sewer laterals on a third of my properties. Glosage Engineering is one of the most professional crews I have delt with. From here on out I will only use them. They leave the property cleaner than when they arrived and the teamwork is unmatched. I can't thank them enough for what they did. Thank you guys, I look forward to seeing you on the next job. read more

The only thing I have to say about this company is that the owner and crew were AMAZING. The communication was perfect and the execution of the sewer lateral was impecable. I would use their services again and most definitely recommend them to others. read more

Luis and his crew repaired the sewer lateral and installed drainage for my newly purchased home to bring it into compliance. I have nothing but good things to say about him and his crew, and the experience overall. Before doing the sewer work, Luis came over to the house and took the time to explain the entire process to me and showed me where and how the work would be performed. From start to finish he maintained great communication with me and was always polite, cheerful, and a pleasure to interact with. His crew were very professional - they were respectful of the neighbor's property and made sure to clean up after themselves and put everything back as if they were never there. While doing the repair, Luis and his crew discovered additional connections to the sewer lateral that weren't considered in the original bid, but Luis honored his original price. Then it was discovered that one of the downspouts from my roof was illegally draining into the sewer lateral requiring additional work to pass inspection. Luis explained several options to me, including the need to abandon a portion of the sewer and reroute the drainage from the downspout to avoid water pooling around my house. In the end, Luis did the extra work to bring the sewer lateral into compliance all within his original price and quoted me a fair price for the needed drainage work, which his crew completed the very next day. I would highly recommend Luis to anyone needing sewer work based on my experience with him! read more

I got Luis's contact from another contractor and I am not disappointed. Luis was prompt, responsive and professional. He went over all the details of what he was planning on doing and got all the paperwork completed. He sent the pictures of the work and kept me updated on what was going on. All I had to do was pay the check at the end. And above all the check I wrote was much lower than what others were charging. I definitely recommend Glosage Engineering read more

Luis is very personable and honest. His price was very fair. He was timely, kept to a schedule, and coordinated all the necessary permits with the county. I was most appreciative that he put all my irrigation back where it originally was. I will have another project coming up on another property and will definitely call him again. Thank you Luis! read more

Luis was very professional and a good communicator. His crew got the sewer lateral job done on our house with no hassles and a reasonable cost.

I was in a real crisis when I contacted Glossage Engineering. I put my home up for sale AND IT SOLD IN 1 DAY! I found out at the last minute I needed a sewer line abatement certification to complete the sale! I called several plumbing abatement companies. Luis answered promptly, gave me all the particulars and when we had a quote I accepted, he and his crew just got to work! He even called and confirmed completion with a detailed email and invoice even though I was out of state! What a great experience. Excellent service, just top drawer. Professional, friendly, knowledgable and FAST! I highly recommend Glossage to anyone who needs responsive, knowledgable engineers. read more

The price was very competitive and his crew were very professional, fast and efficient! Luis went above and beyond his responsibilities help me apply for the sewer lateral certificate as well as get all the information to apply for the sewer lateral grant program. He checked in with me by phone to make sure all was well a few days afterwards. He is very responsive and a pleasure to work with. I will surely call him again for any sewer or concrete work in the future. read more
