THE RTPE COMMITMENT

We speak for the structure.

The needs of the damaged property come first. An RTPE explains what the evidence supports, what remains uncertain and what further investigation is needed.

We reject predetermined price reductions and unsupported invoice defense alike. A desired financial outcome must never dictate a technical conclusion.

What makes an RTPE different

Find the right evaluator.

Describe your technical question, location and timing. IDSO reviews the available expertise before making an introduction.

A personal designation.
Your professional identity.

RTPE identifies the professional’s registration. Their own company provides the services.

Registered Third Party Evaluator is used after a person’s name, as in Ken Larsen, CR, RTPE. Registration is maintained by International Dry Standard Organization, Inc. Review each professional’s relevant qualifications, company, services and agreed scope before engagement.

SUBSTANTIATING RESTORATION EXCELLENCE

The property’s needs.
The evidence to explain them.

Sound restoration decisions begin with a clear understanding of the property. We help owners, restoration professionals, insurers and legal teams examine conditions, understand the technical findings and define the questions that still need answers.

Evidence before conclusions.

Observations, testing and project records form the basis of our technical work. Findings should reflect the evidence, regardless of who commissions the assignment.

Expertise matched to the question.

The right specialist brings relevant education and practical experience. We discuss scope, qualifications and potential conflicts before accepting an assignment.

Reasoning you can follow.

Clear reporting explains what was observed, what it supports and where further investigation may be needed.

FOR RTPE REGISTRANTS

Stay connected to the profession.

Your public profile helps prospects find you. The registrant workspace brings together research resources, technical discussion and access to the DryStandard family’s education and services.

Research library content is being prepared. Registrant access is enabled individually by IDSO.

RTPE registrant workspace

A technical voice for the needs of the property.

An RTPE may help define a scope, interpret drying records, review conditions or advise on a difficult technical question. The assignment should reflect the evaluator’s relevant qualifications and experience.

Independence matters: when engaged as a third party evaluator, the professional’s role is to assess and explain the project’s needs, with potential conflicts addressed before work begins.

More than a listing.

Support your independent practice with research, practical tools, visibility and professional connections.
