Boiler Repair Sandown, NH

When your boiler breaks down in the middle of a cold Sandown, New Hampshire winter, you need reliable repair services fast. At Paul the Plumber, we understand that a malfunctioning boiler isn’t just an inconvenience – it’s an emergency that affects your family’s comfort and safety. Our licensed technicians specialize in diagnosing and repairing all types of boiler systems throughout Sandown and the surrounding areas, bringing 22 years of family-owned expertise to every service call.

Boiler systems are complex pieces of equipment that require specialized knowledge to repair properly. Unlike forced-air heating systems, boilers use hot water or steam to distribute heat throughout your home via radiators, baseboards, or radiant floor systems. When something goes wrong, it takes a trained professional to identify whether the issue stems from the combustion chamber, heat exchanger, circulator pump, expansion tank, or any of the numerous valves and controls that keep your system running safely and efficiently.

Common Boiler Problems We Repair

One of the most frequent issues we encounter in Sandown homes is inadequate heating or no heat at all. This problem often traces back to thermostat malfunctions, broken diaphragms, airlocks in the system, or low water levels. Our technicians carry advanced diagnostic equipment to quickly pinpoint the exact cause. Sometimes the fix is as simple as bleeding air from radiators or adjusting water pressure, while other times it requires replacing faulty components like zone valves or aquastats.

Strange noises coming from your boiler system are another common complaint we address. Banging, whistling, or gurgling sounds typically indicate specific problems that need immediate attention. Kettling, which sounds like a tea kettle boiling, often results from limescale buildup in the heat exchanger, restricting water flow and causing localized boiling. We use specialized descaling techniques to restore proper flow without damaging your system. Gurgling noises usually point to air trapped in the system, while banging might indicate delayed ignition or expansion issues that could pose safety risks if left unaddressed.

Professional Diagnostic Process

When we arrive at your Sandown home for a boiler repair, our BBB accredited A+ rated technicians follow a comprehensive diagnostic process. We start by checking the basics: power supply, thermostat settings, and pilot light or electronic ignition status. Next, we examine water pressure levels, which should typically read between 12 and 15 PSI when cold. Low pressure often causes heating failures, while excessive pressure can trigger safety relief valves and create leaks.

Our diagnostic process continues with a thorough inspection of all safety devices, including the pressure relief valve, low water cutoff, and backflow preventer. We test the expansion tank to ensure it’s properly charged and functioning correctly. Using combustion analyzers, we measure flue gas composition to verify your boiler is burning fuel efficiently and safely. This detailed approach helps us identify not just the immediate problem but also potential issues that could cause future breakdowns, saving you money and hassle down the road.

Types of Boiler Systems We Service

In Sandown and throughout Southern New Hampshire, we encounter various boiler types, each with unique repair requirements. Cast iron sectional boilers, common in older homes, are incredibly durable but can develop leaks between sections over time. We’re experienced in resealing these joints and replacing damaged sections when necessary. Steel fire-tube boilers, often found in larger residential and commercial applications, require regular tube cleaning and occasional retubing to maintain efficiency.

Modern high-efficiency condensing boilers present different challenges. These units extract so much heat from combustion gases that water vapor condenses inside the heat exchanger. While this dramatically improves efficiency, it also creates acidic condensate that can corrode components if not properly managed. We service all major brands of condensing boilers, understanding the specific maintenance requirements of each manufacturer’s design. Whether you have a traditional atmospheric boiler or a cutting-edge modulating condensing unit, our technicians have the training and experience to keep it running reliably.

Emergency Repair Services

Boiler failures rarely happen at convenient times. That’s why we offer emergency repair services to Sandown residents, because we treat customers like family and understand the urgency of restoring heat to your home. When you call us for emergency boiler repair, we prioritize your service call and dispatch a licensed technician as quickly as possible. Our service vehicles are fully stocked with common replacement parts for most boiler brands, allowing us to complete many repairs on the first visit.

During emergency calls, safety is our top priority. We immediately check for carbon monoxide leaks, gas leaks, and other hazardous conditions. If we discover any safety issues, we’ll take immediate action to protect your family while working to restore your heat. Our upfront pricing policy means you’ll know exactly what repairs will cost before we begin work, even during emergency situations. We back all our repairs with a 2-year parts and labor warranty, which extends to 3 years if you join our club membership program.

Preventive Maintenance Benefits

Regular maintenance is crucial for preventing unexpected boiler breakdowns and extending equipment life. During our maintenance visits, we perform comprehensive inspections and adjustments that keep your system running at peak efficiency.

  • Annual combustion analysis ensures your boiler burns fuel cleanly and efficiently, reducing energy costs
  • Heat exchanger cleaning removes soot and scale buildup that reduces heat transfer and increases fuel consumption
  • Safety control testing verifies all protective devices function properly to prevent dangerous conditions

Our preventive maintenance services have helped thousands of verified 5-star review customers avoid costly emergency repairs and premature boiler replacement. By catching small problems early, we can often make minor adjustments or inexpensive repairs that prevent major component failures. This proactive approach is especially important for older boilers, where replacement parts may be expensive or difficult to obtain.

H. MacPherson

I would recommend Paul the Plumber 100%. They offered same/next day service. They were friendly, professional and quick – from the office staff to the technicians. Overall an amazing experience from start to finish.

D. Weaver

What a fantastic business. Helped us work with our water district in resolving meter replacement issues. They also fixed a pipe leak that had developed over time. Caleb was wonderful and answered our questions as well as working with the water district engineer on the meter issues. So easy to work with.

T. Minasian

These are the after photos of the Rinnai tankless water heater installation and vent to the outside. It was important to me that the crew was able to use the existing vent hole to the outside to run both the intake vent pipe and the outside vent pipe. It made the job very clean and did not change the appearance of the outside wall. A shout out to Mike E, Caleb, Josh & Corey

J. Shea

John was wonderful. He found the problem right away and fixed it. He checked other outlets just to make sure I would be safe. He explained different programs the company offers also. I’m very happy.

W. Chepren

I made an appointment on line the morning of July 31 and two trucks showed up at 1:00 pm right on time that same afternoon. Both guys were friendly and very knowledgeable. They quickly found the source of the wet patch on my ceiling which wasn’t the plumbing but a problem with the shower curtain. This is the second time I have called Paul. Both times I got outstanding service and will always call on Paul the Plumber for any plumbing problems in the future. Very reasonable cost for the visit.

M. Richdale

Thanks to Mike Vallee from Paul the Plumber for responding to this new customer’s call so quickly. He was courteous, thorough, explained the repair he was doing and left the work area spotless. I highly recommend Paul the Plumber (and Mike!) to anyone looking for a reliable plumbing company.

K. MacCallum

First time customer, and am very pleased with the whole experience. The highlight was definitely with the technicians assigned to the job and their work – Tyree and Corey were clean, polite, well-informed, and very helpful with some of the questions I had along the way. Their work appears to be top-notch, and they made sure no mess was left behind. Will definitely be calling and requesting these two again on any future needs.

D. Marchand

I cannot say enough about this company!!! Their only concern is that you are up and running again with no worries. I’ve had Kyle the plumber, and Josh their electrician out here and both are polite, well trained and you can tell they truly care about getting you back in service. Great service, well trained caring staff! I will never go anywhere else!

V. Vincze

We had an issue with our water…too hard, calcium deposits, and very little pressure in our master bathroom shower only. The techs (Mike E. & Tyler S.) arrived right on time. They were friendly and very personable. After installing our whole house filtration system and successfully finding the issue with our master bathroom, they left the work areas in pristine condition. They were meticulous in their work, and I highly recommend them for any plumbing needs!

K. Bernardo

We’re first time home owners and needed help with some plumbing and adding a filter system. They were able to get a technician scheduled to our house within a day or so of me contacting them. Mike was super helpful and was able to complete all the jobs in a timely manner, and also cleaned up the areas he was working in. Overall a great experience and would definitely use them for future jobs.

S. Baraket

J. Wojo

DJ from PTP was incredibly helpful and knowledgeable. My shower was not draining and it became a bigger project than I thought it would and they came out quickly and were able to fix my problem. Then when my water heater had a slow leak they came back out quickly to attend to it and fix my problem. I really appreciate their hard work. Thank you so much!! Would definitely recommend them.

D. Lefort

Arrived as scheduled to fix a leak from the shower valve. Tried to fix old 30 or 40 year old unit but had to replace with a new one. Quality work, parts and cleaned up when they were done. Would definitely use again.

S. DesMarais

Josh was amazing. He was able to install my ring doorbells with no issues. He also did a great check of my homes smoke detectors and a few electrical plugs. He was thorough, Knowledgeable, and easy to work with. I would definitely use them again.
