What we do

The trade lives in the mechanical room

Most people hear “insulation” and picture an attic full of pink batts. That’s part of the job. The other part — the one you never see, because it’s above the ceiling, in a mechanical room or on a roof — is pipe insulation: insulating the piping and ductwork that make the building run.

That’s where most of our days are spent. Hot and cold water systems, heating risers, sprinkler lines to protect from freezing, ventilation ducts crossing a roof. The kind of work nobody talks about as long as it’s done right.

And when a wall has to be opened, a partition taken down or everything closed back up, we do that too. One contractor on the file.

From bare pipe to finished job

Four layers, no shortcuts

This is what goes onto a piping system, in order. Each layer has one job, and it has to keep doing it for years.

Cross-section of an insulated pipe: the pipe, the insulation, the vapour barrier and the finish Pipe Insulation Vapour barrier Finish
  1. The bare pipe

    An uninsulated hot water line loses heat day and night. A cold line, on the other hand, gets covered in condensation that ends up on the ceilings.

  2. The insulation

    Mineral wool, fibreglass or closed-cell elastomeric: the product and thickness are chosen for the line temperature.

  3. The vapour barrier

    On a cold line, it decides whether the pipe stays dry. Joints, penetrations and ends are sealed, no exceptions.

  4. The finish

    PVC, canvas, aluminium or stainless steel depending on the location. Elbows, tees and valves get preformed covers, never left bare.

What we insulate disappears behind a ceiling. That is why we do it as if everyone were watching.

How we work

Three things that change everything

What separates work that lasts from work that looks fine for a month. Three details, and they all happen in the same place: wherever the insulation is cut.


The vapour barrier, not just the insulation

On a cold system, it’s the vapour barrier’s seal that decides whether the pipe stays dry or starts dripping again in two years. We treat seams, penetrations and terminations as the heart of the work, because that’s what they are.


Elbows and valves, not just straight runs

Anyone can cover ten feet of straight pipe. What separates a well-built mechanical room from the rest is what happens at elbows, tees, flanges and valves — where the insulation has to be cut, fitted and closed without leaving a thermal bridge.


A site you can walk through

Our mechanical rooms are clean when we leave. That isn’t vanity: a messy room hides defects, a clean one shows them. We would rather they show.
