What is the ground like in Hertfordshire?
Rickmansworth (HA6, WD3, WD18) has around 25,000 residents and sits in Hertfordshire. Nearby places we cover include Watford (4 miles), Gerrards Cross (5 miles) and Amersham (6 miles).
Much of Hertfordshire sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Hertfordshire: garden-city houses in Letchworth and Welwyn, 1930s semis, Victorian terraces and post-war new-town estates.

Which repair method suits a home in Rickmansworth?
Engineer’s structural inspection and report
A chartered structural engineer visits, records the cracks, checks the walls, floors, drains and nearby trees, and writes a report on the likely cause and next steps. It may recommend monitoring, investigations such as trial pits, or a repair specification.
Best for: A first expert opinion on any significant cracking
Tell-tales and crack-width monitoring
Gauges are fixed across key cracks and read at set intervals, or reference studs are measured with callipers to a fraction of a millimetre. The readings show whether each crack is widening, closing or stable, and whether any change follows the seasons.
Best for: Tracking individual cracks over the seasons
What happens when we carry out structural surveys and crack monitoring in Rickmansworth?
Free initial assessment
Send photos of the cracks with something for scale and tell us when they appeared. We give a free view on whether an engineer’s inspection is worthwhile, and whether your insurer should be told first.
Install monitoring points
Tell-tales, measuring studs or level points are fixed at the locations the engineer chooses. A base reading is taken on the first visit, so every later reading can be compared against it.
Repair or close
If the readings show the house is stable, the engineer specifies the repair and we confirm a fixed price in writing. If movement continues, the cause is investigated further before a foundation repair is designed.
Signs you may need structural surveys and crack monitoring

Rules for structural surveys and crack monitoring in England
Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.

Why do houses in Hertfordshire crack?
South Hertfordshire around Watford, Borehamwood and Potters Bar is London Clay, while the north and west are chalk with clay-with-flints and the east has boulder clay. The clay areas are prone to seasonal subsidence near trees. Only an investigation can say why a particular building has moved.
What do BRE crack categories mean?
BRE Digest 251 groups damage by typical crack width. Category 0 is under 0.1 mm, 1 up to 1 mm, 2 up to 5 mm, 3 from 5 to 15 mm or several of about 3 mm, 4 from 15 to 25 mm, and 5 usually over 25 mm. It is a guide to severity, not a diagnosis of cause.
Who carries out the crack monitoring?
An independent chartered structural engineer designs the monitoring and interprets the readings. We can arrange the engineer for you. We are the repair contractor, so we carry out the repair the engineer specifies once the monitoring has shown what is needed.
