Mastic Sealing — Accessible Runs

Brushed-on mastic with reinforcing mesh at every accessible joint, boot and plenum connection. Where we can reach the seams, this is the more durable and far cheaper option, and it is what we will recommend first on an attic system with open runs. What it will not do is fix leaks inside a wall — if the inspection shows the leakage is mostly concealed, mastic alone is the wrong purchase.

How this part is bought

The part follows the finding

No part in this store is a loose transaction. This one links back to the graded inspection that surfaces the need, and across to the install service it belongs to — both performed by the same trained crew.

Every store quote includes

  • A fit check — return area, static pressure, run condition and access verified against your assessment
  • Written installed pricing before anything is ordered
  • Installation to the component's listing by trained technicians
  • Documentation that closes the finding — so the warranty, your insurer, and the next inspector all see a job done right

No price is listed — that’s the standard, not a sticker. Installed pricing depends on your system's static pressure, run condition, and access, and we confirm it in writing after a fit check. No payment is taken online.

Last thing

Get it inspected. Get it in writing.

A $99 camera inspection is the cheapest way to find out whether you need us at all — and a real share of them end with “not yet”. Either way you keep the footage.
