Loose Fill Insulation Queen Mary Park

Loose-fill insulation in Queen Mary Park, measured rather than estimated

Blown-in material fills the awkward parts of an Queen Mary Park building that batts leave gapped — around cross-bracing, over the top plates of interior walls, into the shallow triangle at the eaves. It settles over time, which is why it is specified at a settled depth rather than the depth it looks on the day. Air sealing comes first, because loose material laid over an open ceiling penetration hides the leak instead of stopping it.

• Even coverage carried right out over the top plates
• Depth read back at the corners, not just where the hatch is
• Existing material assessed — topped up, or removed if it is wet or contaminated
• Baffles at the eaves so soffit venting stays clear
• Settled depth specified and marked before the hose starts
• Ceiling penetrations air-sealed first, not buried

Loose Fill Insulation Queen Mary Park: your questions answered

Can you just add over what is already up there?

Usually, and it is the best value if the existing material is dry, even and uncontaminated. If it is damp, matted, rodent-affected or hiding unsealed penetrations, adding over it buries the problem — we tell you which one we found.

Do you seal before blowing?

Yes, and it is the step most often skipped. Loose material laid over an open ceiling penetration hides the leak rather than stopping it, and the warm moist air coming through is what wets the insulation from inside.

What if you find old wiring?

If we find wiring that must not be covered, we stop and say so rather than blowing over it. That is an electrician's call, not ours, and it is a real reason a job gets paused rather than finished the same day.

Can you blow insulation into my walls without opening them?

Often yes — dense-pack through small holes, packed hard enough that it does not slump and leave a cold band at the top. The holes then need filling and finishing, which is drywall work, so we quote that with it rather than surprising you.

How is old insulation removed?

With a vacuum and hose into sealed bags, not shovels, because disturbing decades of settled material raises a lot of dust. It also gives a clean deck to air-seal and a look at the structure before it is covered again.

How messy is it?

Dusty — the machine sits outside and a hose runs through the house to the hatch. We protect the route, seal around the hatch and vacuum afterwards. What the house looks like at the end is most of the difference between crews.
