Boiler Replacement & Installation Services in Seattle, WA

Boilers work quietly in the background of a lot of Seattle homes, especially in older Ballard, Fremont, and Wallingford bungalows built with radiant or radiator heat in mind. When a boiler starts to fail, it rarely happens all at once. It usually shows up as a string of small frustrations that build over a season or two until, one day, the system just cannot keep up anymore. Craftsman Plumbing has helped Seattle homeowners install and replace boilers since 2014, and we bring the same upfront pricing and clear communication to every heating job we do, to every drain, water heater, and repair call.

Our team walks you through your options in plain language, not jargon, so you can make a decision that fits your home and your budget. That is the whole idea behind our No Mansplaining Guarantee. You get honest answers, straightforward pricing, and zero pressure, whether you are replacing a boiler that finally gave out or installing one in a home that never had one. We know boiler work can feel intimidating, and we built our process around making sure it isn’t.

Monty showed up on time and kindly walked me through the service needed to fix the low water pressure in the shower. He quickly understood how to fix the problem and was incredibly efficient and thoughtful throughout the process. He did a great job, and I am very satisfied with the results. Thank you for the excellent service!

My wife and I live in a 120 year old house and when some old metal pipes backed up and started leaking we called the right people. Cameron came out and did a thorough inspection and clearly explained what was going on. Next morning, came out removed the old pipes and installed new ones. Problem solved and we couldn’t be more satisfied with his help.

OMG! Fantastic and quick service!  Found a wet spot in the basement ceiling. Cameron was out the next day shortly after we called, found the problem, gave us our options, and began work immediately. While we were at it, we had our kitchen faucet replaced!  Cameron was very nice, very thorough, and stopped to give our dog a pet each time he went in and out to his truck.  Highly recommend.

Signs Your Boiler Needs to Be Replaced

Boilers tend to give off warning signs well before they fail. Here are the usual signs that point to a replacement rather than another repair.

  • Rising energy bills
  • Frequent breakdowns
  • Uneven heat around the house
  • Strange banging or gurgling noises
  • Water is pooling near the unit
  • Rust or corrosion on the tank
  • The boiler is older than 15 years
  • Constant need for repairs

Seattle’s damp climate adds extra strain to aging boiler systems. Moisture in the air can accelerate corrosion on components already showing wear, and our long, wet winters mean your boiler is working overtime for months at a stretch. If your system is already struggling, that added workload tends to surface problems faster than in drier climates.

Homeowners in older neighborhoods sometimes assume a noisy or inconsistent boiler is just part of owning an older house. In reality, those symptoms usually mean the system is nearing the end of its useful life. Catching the signs early can save you from a mid-winter breakdown, which is never a fun call to make when temperatures drop, and the rain won’t let up.

What to Expect From Our Boiler Installation Process

We start with a full evaluation of your current setup, or your home’s layout if you are installing a boiler for the first time. Our technician considers your square footage, insulation, existing ductwork or radiators, and hot water needs to recommend a system sized correctly. Getting the sizing right matters more than most homeowners realize, since a boiler that is too large or too small will cost you comfort and money for years to come.

Once we land on the right system, we give you a clear, upfront quote before any work begins. There is no fine print and no pressure to upgrade beyond what your home actually needs. Our team explains what each option covers and why, so you understand exactly what you are paying for and why it fits your situation better than alternatives.

Installation day typically involves removing the old unit, if applicable, setting up the new boiler, connecting it to your existing lines or radiators, and thoroughly testing the system before we consider the job finished. We also walk you through basic maintenance and what to watch for going forward. Seattle’s older housing stock sometimes means surprises behind the walls, and if that happens, we talk you through it before touching anything, not after.

Once the new system is running, we will do a final walkthrough with you so you know how to operate it and who to call if anything feels off. Our goal is for you to leave that conversation feeling informed, not confused, no matter how much or how little you already knew about boilers going in.

Advantages of a New Boiler System

A new boiler does more than just heat your home again. Modern systems run significantly more efficiently than units from ten or fifteen years ago, which often shows up directly in lower monthly energy bills. That efficiency also tends to mean fewer emergency repair calls, since newer components are built to handle consistent use without the wear that older parts accumulate.

Comfort improves, too. Newer boilers distribute heat more evenly throughout the home, which matters a lot during Seattle’s long stretch of cool, wet months when a home can otherwise feel warm in one room and chilly in the next. Many updated systems are also quieter, so you lose the clanking and gurgling that older units are known for, which makes a real difference in open-plan homes where sound travels easily.

There is also a safety upside. Aging boilers are more prone to leaks, corrosion, and, in rare cases, carbon monoxide concerns. A new system reduces those risks and gives you peace of mind heading into another wet Pacific Northwest winter, especially if your home has gone several seasons without a full heating system inspection.
