How long a Hemel Hempstead garden wall takes
A typical 4–6m front boundary wall in Hemel Hempstead takes 5–8 working days from footing to cap; longer runs, piers and gates scale linearly. We price by the linear metre for the wall plus itemised for foundation, piers and any pier caps or gate posts.
Foundation and ground in Hemel Hempstead
Hemel sits on chalk with clay-with-flints, but the New Town's heavy 20th-century earthworks mean made-ground is common — we always test before pricing structural work. A Hemel Hempstead garden wall needs a proper strip footing to the frost line — typically 450mm below ground, wider than the wall thickness — and reinforced across any known soft spot. Skip the trial hole and you'll be back rebuilding in five years.
Brick, mortar and design
New Town areas like Adeyfield, Bennetts End and Grovehill are predominantly 1950s–1970s concrete-frame and cavity brick; the Old Town and Boxmoor have substantial Georgian and Victorian period stock. Choose the brick to match the closest wall on the street. On pre-1919 Hemel Hempstead property that usually means a lime-mortared soft red or stock; on interwar and post-war Hemel Hempstead property, a cement-mortared multi-stock. Piers every 3m on any wall over 900mm high, brick-on-edge or purpose-made cap on top.
Planning and boundary rules in Hemel Hempstead
Dacorum Borough Council protect the Old Town High Street Conservation Area and Boxmoor's character carefully, while New Town estates often carry estate-management covenants on front-of-property changes. Front walls in Hemel Hempstead up to 1m and rear walls up to 2m usually sit under Permitted Development, but Hertfordshire Conservation Areas, corner-plot sightlines and shared-boundary work all bring extra checks. The Party Wall Act applies if you're touching a shared boundary or excavating within 3m of a neighbour's foundation.

FAQs — garden wall guide in Hemel Hempstead
Do I need planning permission for a garden wall in Hemel Hempstead?
Front walls up to 1m and rear/side walls up to 2m usually don't in Hemel Hempstead, but Conservation Areas, corner plots and highway sightlines can override that.
Do you cover Apsley and Leverstock Green?
Yes — both sit in our normal Hemel coverage along with Boxmoor, Adeyfield, Bennetts End and Grovehill.
How deep does a Hemel Hempstead garden wall foundation go?
Hemel sits on chalk with clay-with-flints, but the New Town's heavy 20th-century earthworks mean made-ground is common — we always test before pricing structural work. Typically 450mm to hit stable bearing, wider than the wall thickness, mass-concrete. Decided on site after a trial hole, not off a template.
Can you work on Old Town Hemel Hempstead Conservation Area properties?
Yes — we use matching brick, lime mortar and traditional joint profiles on Old Town and Boxmoor work, and we'll bring samples on site before agreeing the spec.
