Keystone

One expert in charge of the whole problem, from the first question to the verified fix.

For large homes, estates, several properties, failed remediations and households where health is on the line. We investigate, write the plan, line up the right professionals, keep the work in the right order and verify the result, so it does not become your second job.

The problem Keystone solves

Six professionals. Six reports. Nobody in charge.

The inspector sees the inspection. The lab sees the sample. The remediator sees the cleanup, the contractor sees the rebuild, the HVAC company sees the equipment and the doctor sees the patient. On a big property that turns into months of calls, conflicting advice and money spent in the wrong order. Keystone is the one person holding the whole picture.

How it runs

Six steps, in order.

1. Property

How the building is built, how it is used, what has happened to it, and every report that already exists.

2. Investigation

On-site where it is needed: moisture, air movement, HVAC, the building envelope, and sampling only where it answers a question.

3. The plan

One written plan: what happens now, next and later, who does each part, and what "done" means.

4. The team

We find and brief the right remediators, contractors, HVAC and engineers, and review their scopes before you sign.

5. The work

We keep the sequence right: moisture fixed before cleanup, cleanup verified before rebuild.

6. Verification

Defined criteria, checked and documented, so finished means finished and not just invoiced.

Who it is for

Keystone fits when:

  • The property is large, custom or technically complicated
  • There is more than one home involved
  • The problem survived an earlier inspection or remediation
  • Someone in the home has significant health concerns or sensitivities
  • A renovation or rebuild is coming and must not make things worse
  • There is an insurance claim, a dispute or a need for documentation
  • You want one discreet point of contact and your time back
Pricing

Every engagement is scoped to the property. After the first conversation and a look at existing records, you get a written scope and price. Nothing starts until you approve it. The first conversation is free and confidential.

Our role

Keystone does not replace licensed medical care, engineering, legal advice or licensed contractors. Each professional stays responsible for their own work. We make sure it is the right work, in the right order.

Experience

Our investigations draw on the same field discipline taught and practiced by Stanley Yeskolski, President of the Indoor Air Quality Association (IAQA), who consults with us on complex cases.
