Get answers to common questions about plumbing services in Dover, New Hampshire.
Dover's harsh winters, with temperatures often dropping below freezing for extended periods, make frozen and burst pipes a major risk. Homeowners should prioritize insulating pipes in unheated areas like basements and crawlspaces, disconnecting and draining outdoor hoses, and ensuring heat is maintained in the home during cold snaps. It's also wise to know the location of your main water shut-off valve in case of an emergency burst.
Yes, all plumbing work in Dover must comply with the New Hampshire State Plumbing Code, which is based on the International Plumbing Code (IPC). Furthermore, any significant work requires a permit from the City of Dover's Building Department, and the work must be performed or supervised by a licensed New Hampshire plumber. This is especially important for projects like water heater replacements, bathroom additions, or sewer line work.
Pricing varies by company and job complexity, but for standard service calls in the Seacoast region, you can expect a base service fee of $100-$200, plus parts and labor. For example, fixing a common leaky faucet might total $150-$300, while hydro-jetting a severely clogged main drain could range from $400-$800. Always request a detailed estimate before work begins.
Always verify that the plumber holds a current New Hampshire Master or Journeyman Plumber license. Look for established local companies with strong community reputations, proper insurance, and clear warranties on their work. Checking reviews specific to Dover and the Seacoast area can also provide insight into their reliability, especially during winter emergencies when response time is critical.
Yes, many historic and older homes in Dover's neighborhoods like Bellamy Park or the downtown area have original cast iron sewer lines. These pipes are prone to corrosion, bellies, and root intrusion over time. A local plumber can perform a video camera inspection to assess their condition. Options range from targeted repairs to trenchless pipe lining (CIPP), which is often ideal for minimally disrupting Dover's mature landscapes and paved surfaces.
