What matters for radiator repair in Maplewood
Leaking radiator valves
Old radiator valves leak at the stem and packing. Replacing them stops water damage to floors below.
Air in upper floors
Air collects at the highest points of the system, so top-floor radiators are the first to go cold and gurgle.
Pressure in taller buildings
Three-story buildings need enough system pressure to push water to the top floor. Low pressure leaves upper units cold.
Warning signs to watch for in Maplewood homes
- One zone or floor cold
- Gurgling or rushing water sounds
- Radiators hot at bottom, cold at top
- Water stains under a radiator or baseboard
- Pressure dropping over days
