"Robert Johnson Plumbing was excellent from beginning to end. Robert himself responded to my urgent Angi request within minutes on a Saturday, and they installed our new water heater Monday morning. His quote was less than half of what a large firm had quoted us. Robert took the time to explain our options rather than simply replacing our aging propane heater with the same thing. His recommendation led us to a hybrid electric water heater that is expected to reduce our yearly energy costs. Installation took about 3–4 hours with two plumbers and a contracted electrician. Everyone was helpful, respectful and professional, and they left the basement cleaner than they found it. They explained the new system and made sure I knew where to turn for future care and maintenance. Professional, kind and transparent throughout. I would absolutely recommend them."

"Exchanged messages with Mike to describe work needed, replace an outdoor faucet and shutoff value (previous faucet was leaking). He gave an estimate, reviewed work to be done. Replaced outdoor spigot with a frost-proof spigot, put on new value. Quick test and validation. Professional, efficient and happy with work done! Thank you Mike !"

"Dustin was excellent. Showed up on time and was extremely professional. He fixed what was broken, hooked up what needed to be hooked up and got my kitchen and shower running beautifully. He didn't try to upsell or convince me to replace things that didn't need fixing or replacing. I have definitely found my new plumber! Would strongly recommend."

"The entire process was really great. We always felt that Jeff was trying to satisfy our wants and needs not trying to sell us something. From beginning to end the whole process was very professional. The install crew was very good, professional and considerate of our home. The install was perfect and finished in one day as promised and the cleanup was so good you would never know that any work had been done in the bathroom. I highly recommend Clouds 9 Tubs. They are a top shelf organization and we are very pleased with their work. Also every appointment we had from beginning to end they were always on time."

"There is NEVER a 'good' time to have plumbing issues but we were super happy to hear Mr. Rooter could send a plumber for same day service for our issue. Your plumber was very polite, helpful, careful of property, and knowledgeable. He also solved our sink issue in a very timely manner. We will definitely be calling Mr. Rooter for future plumbing issues as your services have been shown to be most reliable, competitively priced, and performed in a timely manner."

Plumbing questions, answered by experts

Treat frozen lines, burst pipes, and sump pump failures as immediate emergencies. NH winters and spring thaws cause rapid water damage, making fast action essential. Address failed code inspections or lead service lines right away to meet strict compliance deadlines. Schedule non-leak fixture upgrades and minor drips for later. Book non-emergency plumbing before October to avoid winter delays.

Helpful?

Inspect your foundation and framing. Dover homes built before 1950 feature balloon framing and fieldstone foundations, which restrict pipe access and complicate routing. Converted multi-family structures possess non-standard layouts and shared stacks that make individual unit repairs difficult. Additionally, shallow bedrock and crawl spaces severely limit options for rerouting exterior lines and insulating pipes against the cold.

Helpful?

Prepare for freezing temperatures by keeping high-quality pipe insulation on hand for exposed lines in crawl spaces and garages. You must know the exact location of your main water shutoff valve and verify it functions correctly before winter hits. For NH homes on private wells, keep a close eye on your pressure tank and pump conditions to maintain a healthy system.

Helpful?

Historic homes in Dover contain galvanized steel pipes, cast iron drains, or lead service lines that require full replacement rather than simple spot repairs. High water tables near the river and rocky ledge make excavation difficult. Additionally, properties on private septic systems or within historic districts face strict regulatory oversight that complicates exterior plumbing and drainage work.

Helpful?

When hiring for plumbing, watch out for contractors who lack a state license or cannot provide proof of liability insurance. In Dover, professionals must pull permits for most work. Avoid quotes that omit permit fees or contractors who discourage the process. Finally, demand itemized breakdowns during winter emergencies to ensure contractors disclose all seasonal surge markups clearly.
