Local property context

Property and moisture across Hertfordshire

Hertfordshire holds an unusually clear record of twentieth-century housing policy. Letchworth and Welwyn were built as garden cities, Stevenage, Hatfield and Hemel Hempstead expanded substantially as designated new towns, and the housing of those eras — solid or early-cavity walls, original airflow provision, later insulation and window replacement — behaves in ways that are well understood once a surveyor knows what to look for.

Alongside that, the older market towns and the Chilterns fringe contain listed and conservation-area property where remedial work has to be proportionate and sympathetic. We regularly assess buildings where an aggressive damp-proofing specification has been proposed and the evidence does not support it.

Our approach

What happens during your survey in Hertfordshire

The purpose of a survey is to identify the underlying cause of the moisture, not to justify a particular treatment.

3Reviewing what you already haveExisting reports, building surveys or previous quotations are read before the visit.
4Choosing the right surveyThe survey type is matched to the problem rather than sold as a package.
5Inspecting the propertyInternal and external inspection, moisture and psychrometric readings, photographs.
6Considering moisture sourcesConstruction, ground levels, rainwater goods, airflow, heating and occupancy.
7Clear written findingsWhat was found, what it means, and where the evidence is inconclusive.
8Recommended next stepsIn priority order, with the reasoning behind each recommendation.
9Quoting only where work is neededItemised, with assumptions and exclusions stated.
10Portal access throughoutReports, quotations, project stages and documents in one place.

Questions

Frequently asked questions — Hertfordshire

Do you work in the parts of Hertfordshire close to Greater London?

We cover Hertfordshire, including Borehamwood, Potters Bar, Bushey, Cheshunt and Waltham Cross. We do not operate inside Greater London.

Can you assess a listed or conservation-area property?

Yes. The investigation is the same, but the recommendations take account of consent requirements and the need for breathable, reversible repairs where appropriate. We will say plainly where specialist consent is likely to be needed.

Do you support property owners managing several properties?

Yes. Agents and property owners get property records-level visibility of surveys, quotations, works and documents through the portal, which is generally easier than tracking individual jobs by email.
