"Excellent experience. Compared to all the other plumbers who came out an gave an estimate I could tell that Henco new what they were doing and showed confidence. Loren was an excellent problem solver and was able to accomodate my request to move the whole soil stack 5 feet to an exterior wall. Very happy with the work. An additional nicety was they had a "build back" guy (Chad) they had available to restore surfaces and paint. Very convenient. Finally, all projects have hiccups... mishaps can happen but I am glad to say Owen was very fair and reasonable to deal with. Overall I highly recommend Henco. I have already recommended them to multiple neighborhood friends. Everyday I use the plumbing I smile."

"Wow! I was so impressed with our experience! Phil went above and beyond to fix and replace our shower cartridge quickly and efficiently. He’s passionate about his work and educates the customer along the way - I learned so much from him that I didn’t know about our home systems and plumbing. He was punctual, polite and professional. And very knowledgeable! We will definitely be hiring this company for any future plumbing or drain issues. Their customer service was incredible."

"Sam was very professional, courteous, and knowledgeable. He even gave me tips to keep my plumbing in check. He replaced a garbage disposal, unclogged a drain, repaired toilet, and replaced a plastic pipe. Pricing was fair and got discounts. I chose Henco based on reviews and their high standing with the BBB. So glad I found this company! They have a customer for life."

"Summit plumbing was fabulous from start to finish on my project. I hired them for a tub to shower conversion in my condo. Bob (one of owners), and Tyler did such a great job and were extremely easy to work with. They cleaned up the job site at the end of each day. When done, I had a minor problem with water leaking from the pivot shower door. The day I called, Bob was at my house within the hour and came again the next day when the issue wasn't initially resolved I'm happy to say he fixed the leak and I'm very happy with my new shower. Everyone I worked with or spoke to on the phone was always very helpful and responsive. Fantastic customer service. I would highly, highly recommend Summit Plumbing and would hire them again. As a matter of fact, before this job I didn't have a "go-to" plumber....I do now. Thanks to everyone at Summit Plumbing for exceptional customer service and a top-notch job!!"

"Called a bunch of big name people and they either never called back or quoted an insane amount. Ryan and Sup. Underground not only showed up on time but left our yard looking better then before our sewer was replaced. Best experience I have had with any contractor in a long time. Great work and even better price."

"Spoke with owner Ross about replacing two water heaters. One was showing wet stains bottom. So I decided to replace both, since they were both about 12 yrs old. I decided to replace my Bradform Whites with a more high tech water heater. I picked Lowe's AO Signature 500, which is their top electric heater. Has leak detection shut off, higher heating element, vacation mode, wifi enabled etc. Labor estimate about $1400 to replace both, and I had the water heaters onsite for install. Can't say enough how Professional his plumbing crew is. Jack and Chris did an outstanding job. They kept me informed throughout the process, and kept my home clean at all times. The install projects came out great and price as agreed. Other plumbing estimates were higher, especially comparing it to those Big Box stores. Will certainly be doing with Ross again in the future. FYI, look for a company that is willing to be open to use other brand name water heaters and not just what they trying to sell you."

FAQs for sewer main install, replace or repair projects in Washougal, WA

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.
