"Can not imagine a better response, starting with my call for assistance, response time and how the technician, Tad methodically diagnosed the problem. We have an obscure kitchen fixture that required service in Feb 2019. Under warranty the problem was easily diagnosed by me, a problem possibly caused by me and a replacement part sent and installed by Albert Nahman team. Problem: I broke the faucet cartridge. Current Problem: restricted hot water flow in this kitchen sink only. Turns out the new cartridge part is now malfunctioning. I called and Tad arrived taking a step by step approach ruling out possible causes: a clog here or there, build up of sediment, or blockage in the lines or cartridge. The company that sells the product got on the phone with Tad and they collaborated on the problem and the tech person gave Tad one more thing to try. After the collaboration it is agreed, problem persisted and therefore that new cartridge part is now malfunctioning and will be shipped free of charge in two days. Thanks to all, who made this possible and I trust we will have Tad here again soon to finalize this fix. BTW, cost of service was less than expected given going rates for such a call lasting in excess of one hour. Another comment, spending time with Tad during the repair was a pleasure to have him explain, collaborate, listen and just chat. Questions on who to call next time, no question who I will call next time. I have read criticism of costs: In the Berkeley area "How much does it cost to hire a plumber? Some plumbers have a minimum fee for a service call. They might charge anywhere from $175-250 to come out and give you a consultation. Plumbers may give you a general service rate of $128-148 per hour when there are a lot of unknowns about a project and they aren't sure how long it will take. Some charge a flat rate for their plumbing services. For example, you may get charged $175 for a sink or drain cleaning, while toilet installation costs $500." Today costs are upfront, same as charges in Feb, $69 to arrive and assess the problem. Here in excess of one hour for $129 minus $25 coupon, total charge $173. I am ok and I expected these costs. If I was in Philly, where I grew up, I could call an uncle or cousin and get a better rate, a family rate. This is going rate for our area."

"They were amazing, giving us up-to-date info on the project and explaining our options to us when unexpected situations occurred (like finding out that the lateral sewer couldn't be connected to the main pipe because it was made of orange burg). They gave us a great price on the sewer as well. I'd hire them again in a heartbeat."

FAQs for sewer main install, replace or repair projects in Diablo, CA

Most trenchless sewer line replacements can be completed within one to three days, though this varies based on your situation. Simple repairs on accessible lines might be finished in hours, while complex systems or challenging soil conditions could extend the timeline. The reduced excavation requirements result in faster completion compared to traditional trenching methods.

Trenchless pipe lining may reduce the interior diameter of your pipes, which could affect flow capacity in already narrow lines. This method also requires the existing pipe to maintain sufficient structural integrity to support the new liner. Severely collapsed sections, major joint separations, or completely misaligned pipes might not be suitable candidates for lining and could require alternative approaches.

Trenchless sewer pipe liners are rated to last up to 50 years when properly installed and maintained. Actual longevity depends on installation quality, usage patterns, and environmental factors like soil movement or tree root intrusion. Regular maintenance and avoiding problematic disposal practices (like flushing non-biodegradable items) can help maximize your system's operational lifespan.

Trenchless technology availability varies by region, with greater accessibility in metropolitan and suburban areas where specialized contractors operate. Some rural locations may have limited access to trenchless equipment and expertise. Local regulations and soil conditions also influence availability. A professional assessment of your property and local contractor options will determine if trenchless methods are feasible for your specific location.

Professional video inspection provides the most reliable assessment of whether your sewer issues suit trenchless repair. Generally, pipes with moderate damage, like small cracks, minor leaks, or partial blockages, respond well to trenchless techniques. Completely collapsed sections, severe misalignments, or extensive structural failures might require traditional excavation. Consulting with contractors who offer both methods ensures you receive unbiased recommendations.

Quality trenchless sewer replacement often includes a workmanship guarantee from the contractor. The specific terms vary by company and region, but many professionals stand behind their installation for at least one year. Material warranties may extend longer, depending on the pipe products used. Always request written warranty information before hiring, and understand exactly what's covered and what might void your protection.
