What Services Do Dover Plumbing Companies Offer?

Leak Repair

Leaking pipes that aren't addressed promptly can increase your water bills and harm the nearby area. A plumbing specialist can find the exact point of the leak and repair it directly at that spot.

Clog Repair

Obstructed pipes and drains may result in backflow, flooding, and water damage. Dover plumbers have the proper equipment to clear blockages. They'll also give you advice on avoiding future problems.

Pipe Replacement

Pipes become damaged over time. If they show signs of leakage or warping, they might need replacement. A plumbing expert in Dover can assess your pipes' health and swap out aged and damaged parts with new, durable materials.

Fixture Installation

Fixtures don't last forever, and they'll start to leak over time. You may also want new fixtures as part of a bathroom or room remodel. No matter your motivation, professional plumbers can install new toilets, sinks, showers, and bathtubs with precision and ease.

Gas Repair

In addition to typical plumbing services, some professionals are trained to fix home gas leaks from appliances such as ovens and radiators. If you notice the scent of a gas leak, exit your house right away and call your utility company.

Annual Inspections

Your plumbing system ages over time, so scheduling regular annual inspections from a certified Dover plumbing company is crucial for its longevity. Technicians can identify problems early and save you money in the future.

Emergency Services

There's never "the right time" for plumbing emergencies like burst pipes and overflowing toilets, but what if you can't wait for repairs? To get your home back to normal quickly, many Dover plumbing companies have crews on-call to handle immediate situations. Though emergencies are pricier than scheduled maintenance, it's necessary at times to avoid extensive damage.

Cost of Plumbing Services in Dover

The cost of plumbing services in Dover ranges from $122 to $406. Costs will vary depending on the extent of the issue, and you'll pay more for emergency services and repairs. Below are the average costs of common plumbing repairs in Dover.

ProjectEstimated Cost
Clog and drain clearing$83 - $417

Check Licensing and Insurance

New Hampshire plumbing company owners must carry a journeyman or master license from the state's Mechanical Safety and Licensing Board. A separate license is required for fuel gasfitting and piping installation. To protect yourself financially against damage or accidents, you should also ensure your plumber is bonded and insured.

Check Union Status

Plumbers who are part of state or national trade unions tend to charge more for labor. However, many Dover homeowners prefer them because the union requires strong vetting and training standards.

Assess Their Experience

Plumbers with extensive local experience will be more familiar with Dover's most common plumbing conundrums. By choosing a small plumbing company, you could get issues handled faster.

Read Customer Reviews

Read through customer reviews on sites like Google Reviews and the Better Business Bureau (BBB). Pay attention to what past clients have said about a plumber's customer service and workmanship.

Compare Multiple Quotes

Seek out multiple estimates for your project to determine the local market rates. Steer clear of companies that charge excessively high or low for their services. If a quote looks "too good to be true," it probably is.

Ask About Warranties and Guarantees

Many plumbing companies offer service warranties to protect you in case an issue returns within a given timeframe. You should also ask about warranties on any new appliances, such as sinks and toilets, that you're having professionally installed.

Frequently Asked Questions About Plumbing in Dover, NH

Plumbers can fix these common problems:

  • Clogged drains
  • Lack of hot water
  • Low water pressure
  • Leaks and water damage
  • Running toilets
  • Septic and sewer line issues

You're not expected to tip your plumber. You may offer a tip for exceptional service, but first, ensure the company you've chosen doesn't bar its employees from accepting them.

Some Dover homeowners do fix running toilets and unclog drains themselves. However, even if you choose to DIY, you should still have a professional plumber on speed dial in case the issue recurs or you can't figure out the cause. An improper "fix" can cause significant damage.

Many plumbers offer both online and over-the-phone scheduling. For emergency services, you'll need to call directly.

Plumbers can fix water heaters if their license allows it. If your water heater leaks, makes unusual noises, doesn't properly heat your water, or is more than 8–12 years old, schedule a professional inspection. Water heater components can be dangerous, so we highly advise leaving repairs to trained plumbers and gas technicians.
