Radiant Floor Heating in Portland, ME
J&R Mechanical Services provides radiant floor heating in Portland, Maine, part of our Cumberland County service area. J&R Mechanical Services installs hydronic radiant floor systems for new construction and renovations.
How Radiant Floor Heat Works
- Boiler — heats water for the loop
- Manifold — splits and balances flow to each loop
- PEX tubing — embedded in the floor slab
- Radiant floor — warms the slab evenly
- Heat rises — gently warms the room above
Radiant Floor Heating for Portland Homes
Hydronic radiant floor heating works by circulating warm water through PEX tubing installed beneath your floors. The heat radiates evenly across the floor surface, warming the room from the bottom up for consistent, draft-free comfort.
Where Radiant Floor Heat Makes Sense
New construction and gut renovations are the sweet spot — tubing goes into the slab or subfloor while everything is open, and the whole home can run on silent, even radiant heat. In existing homes, the best-value targets are the rooms where cold floors actually hurt: bathrooms, kitchens, mudrooms, and basement or garage slabs being finished into living space. Staple-up installation under an accessible subfloor lets us retrofit radiant into first-floor rooms without tearing up the finished floor. Radiant is also one of the most comfortable options for cold-climate winters in a physical sense: the warmth lives at floor level where you are, instead of stratifying at the ceiling, and there is no blower pushing dust or drying the air. Design is everything, though — tube spacing, water temperature, zoning, and floor covering all interact, and a poorly designed radiant floor is expensive to correct. We engineer each system before a foot of PEX is stapled.

Radiant Floor Heating in Portland, ME FAQs
Do you offer radiant floor heating in Portland, ME?
Yes. Portland is part of our Cumberland County service area, and J&R Mechanical Services handles radiant floor heating for homes throughout the area. Call (207) 902-8899 or book online to schedule.
Does radiant floor heating work under wood and tile floors?
Yes. Tile and stone are the best conductors and feel warmest; engineered wood and many hardwoods work well when water temperatures are designed for them; even carpet can work with the right pad. We design the tube layout and water temperature around your specific floor covering.
Can radiant floors heat my whole house?
Yes — with a properly done heat-loss calculation and design, hydronic radiant can be the sole heat source for a home. In retrofits, many homeowners run radiant in key rooms and keep baseboard or a heat pump elsewhere, all off the same boiler with separate zones.
