What Separates A Good Spray Foam Insulation Job From A Bad One
Good material sprayed badly is still a failed spray foam insulation job, and the failure looks identical to the person paying for it. Shrinkage. A smell that will not clear. Spray foam insulation pulling back off the framing. None of that is the insulation's fault.
Three things decide it, and all three happen before anyone sees a finished wall. The two components have to meet in the right ratio, which means equipment that is maintained and monitored rather than assumed. The substrate has to be above the insulation's minimum temperature, measured at the surface and not at the room. And the applied depth has to be checked as it goes on, not estimated afterwards.
Ask any spray foam insulation contractor you are considering how they handle those three. The answer tells you more than anything on a website, including this one.
We keep a daily log: substrate temperature, conditions, product lot numbers and applied depth. If a question ever arises about a job, the answer already exists on paper.
Getting To A Price
Somebody comes and stands in the space. There is no estimate over the phone, because depth follows from what the assembly has to achieve and nobody can see that down a telephone line.
We measure, check for moisture, read the substrate temperature and identify anything that has to be handled first.
You then receive a written specification: product, depth, areas, the covering that follows, and a single price. Not a range, and not an hourly figure that grows.
Advice Most Quotes Leave Out
Sometimes spray foam insulation is the wrong material, and sometimes it is simply the wrong year for it. We say so.
Water coming through a roof gets stopped first. Insulation does not go near it until that is settled.
Where money is tight, we will tell you that the floor band and general air sealing will do more this year than a full basement would, and that the basement can wait.
Where open cell will do the work for half the outlay, we say so instead of quoting the dearer product because it is the dearer product.
Where a space needs covering afterwards, you hear it at quote stage, while it can still change what you decide.
Working In Somebody's House
The space is masked and protected before anything is applied. Anything that should not receive spray foam insulation is covered.
Spray foam insulation goes on in measured lifts so it cures correctly, then it is cut back flush so board sits flat against it.
Ventilation is mechanical, and the re-entry window set by the insulation manufacturer is in your hands in writing beforehand. Nobody goes back in ahead of it.
Offcuts and trimmings leave with us.
