Boiler Repair.
Fixed, Not Replaced.
Cold radiators, pressure that will not hold, kettling that sounds like a tea party in the basement: boiler problems are almost always a failed part, not a failed boiler. Circulators, zone valves, aquastats, expansion tanks, ignition: all repairable. We do not sell or install boilers, so nobody is going to talk you into replacing a 25-year appliance that needs a $300 part. Plenty of older homes in and around Tillsonburg run hot-water heat: cast-iron radiators downtown, baseboard hydronics in the post-war neighbourhoods, and propane-fired boilers on the farms south toward Courtland and Brownsville.
Hydronic heat down?
Match your symptom.
Plenty of older homes in and around Tillsonburg run hot-water heat: cast-iron radiators downtown, baseboard hydronics in the post-war neighbourhoods, and propane-fired boilers on the farms south toward Courtland and Brownsville. We repair all of them. Cast-iron rads, baseboard loops, in-floor, combi units: the failure patterns repeat, and most come down to a handful of serviceable parts.
No heat at all
Usually ignition (pilot, igniter, flame sensor), the aquastat, or a failed circulator. All diagnosable in one visit and repairable on the spot in most cases.
Some radiators cold
Air trapped in the loop, a stuck zone valve, or a circulator running weak. A purge and rebalance, or a valve/pump repair, brings the cold rooms back.
Losing pressure
A weeping relief valve, waterlogged expansion tank, or a small system leak. We find where the water is going and fix that, not just top it up.
Kettling / banging
Scale on the heat exchanger making steam pockets, or flow starvation. It is loud and inefficient, and it shortens boiler life. Fixable.
Combi: heat but no hot water
Combi boilers (Viessmann, NTI, Navien and the rest) have a separate DHW path: diverter valves, plate exchangers, flow sensors. All serviceable parts.
Lockouts / error codes
Modern boilers lock out to protect themselves. We read the code, trace the actual fault, and clear it properly instead of just resetting it.
Leaking circulator or valve
Pump flanges, zone valve bodies, and shut-offs drip long before they fail. Caught early, this is a routine repair, not a flood.
Short cycling
Oversized boiler, a failing aquastat, or trapped air. Short cycling burns gas and hammers components. We diagnose which one yours is.

Repair or replace?
A well-kept boiler runs 25-40 years, and almost everything on it is a serviceable part: circulator pumps, zone valves, aquastats, ignition modules, expansion tanks, relief valves. The genuine replacement case is a cracked heat exchanger or section on an old unit. We do not sell or install boilers, so our repair-or-replace answer has no install commission behind it: if yours is fixable, we fix it.
