Spray Foam Health Check & Condition Survey

ThermoFoam carries out commercial spray foam health checks and condition surveys — assessing existing insulation, diagnosing condensation and adhesion issues, and producing documented reports for owners, buyers and lenders.

Overview

Why spray foam for spray foam systems

Spray foam installed years ago can quietly deteriorate or simply raise questions at the point of sale, purchase or refinance. Lenders, surveyors and buyers increasingly want evidence that existing foam is sound — well-bonded, dry, and not masking a condensation or substrate problem. Without an informed assessment, a building owner is left guessing about a material they cannot easily see behind or beneath.

A ThermoFoam health check sends an experienced surveyor to inspect the existing foam in place. We assess adhesion to the substrate, look for signs of condensation, trapped moisture, movement or breakdown, and consider whether the original application suits the building. Because we install manufacturer-certified closed-cell systems ourselves, we know what good and failing foam looks like and what a buyer's surveyor will be asking.

The deliverable is a documented condition report setting out what was found, the apparent condition, any concerns and recommended next steps. Owners use it to satisfy a pre-sale or pre-purchase enquiry, support a lender or insurer, plan remedial work, or simply gain confidence that an existing commercial installation is performing as it should.

Why spray foam

The benefits for spray foam systems

Adhesion Assessment

Surveyors check how well the existing foam is bonded to its substrate and flag any debonding, lifting or breakdown.

Condensation Diagnosis

We look for signs of trapped moisture and condensation behind or beneath the foam that point to an underlying problem.

Pre-Sale Surveys

Independent condition reports answer the questions buyers, surveyors and conveyancers raise about existing spray foam.

Lender Evidence

Documented findings give owners something concrete to put in front of a lender, insurer or prospective purchaser.

Clear Report

Every visit ends in a written report covering condition, concerns and recommended next steps — not just a verbal opinion.

Remedial Guidance

Where issues are found, we set out practical options so owners can plan and budget any remedial works with confidence.

Assessing Existing Foam

A spray foam health check is an inspection, not an installation. ThermoFoam surveyors examine existing closed-cell or other spray foam, checking adhesion to the substrate, signs of condensation, moisture and movement, and overall condition — then set out the findings in a clear, documented report owners and buyers can rely on.

A ThermoFoam health check is a condition survey of existing spray foam, not a new installation. Drawing on our experience installing manufacturer-certified Enverge closed-cell systems (Nexseal LE, Duratite UK distributor of record, Agrément 09/4610), surveyors assess adhesion, moisture, condensation indicators and overall condition, then report findings so owners and their advisers can act on clear evidence.

In detail

Specification & compliance for spray foam systems

An existing spray foam installation — ours or anyone else's — deserves a periodic professional check. A ThermoFoam health check takes moisture readings across the installation, reviews the build-up for condensation risk, and inspects adhesion, coverage and condition of the foam.

You receive a clear written report on what was found and what, if anything, needs attention — the documentation building owners, surveyors and insurers increasingly ask for.

FAQs

Health Checks insulation, answered

What does a spray foam health check involve?

A surveyor inspects your existing foam in place — assessing how well it is bonded, looking for condensation, trapped moisture, movement or breakdown, and judging overall condition. It is an inspection and reporting service, not an installation, and ends in a written report.

Why do I need a survey before selling or buying?

Lenders, insurers and surveyors increasingly query existing spray foam. An independent condition report gives buyers and their advisers documented evidence of the foam's state, helping a sale, purchase or refinance proceed rather than stalling on unanswered questions.

Can you tell if the foam is failing or holding moisture?

Our surveyors check adhesion to the substrate and look for the signs that point to condensation or trapped moisture and breakdown. We report what we find and, where there are concerns, recommend practical next steps so you can plan any remedial work.

Do I get a written report I can show a lender?

Yes. Every health check concludes with a documented condition report covering what was inspected, the apparent condition, any concerns and recommended actions — something owners can put in front of a lender, insurer, buyer or their surveyor.

Do you only inspect foam you installed?

No. We survey existing commercial spray foam regardless of who installed it. Because we install manufacturer-certified closed-cell systems ourselves, we know what sound and failing foam looks like and what a buyer's surveyor will be asking about.

Do you check spray foam installed by other companies?

Yes — we assess any existing spray foam installation and report on its condition honestly, whoever installed it.

What does the health check report include?

Moisture readings, a condensation-risk review of the build-up, condition notes on the foam itself, and clear recommendations.

How often should spray foam be checked?

A periodic check — particularly before a sale, refinance or change of building use — keeps the documentation current and catches issues early.
