Old Hatfield, new town
Old Hatfield clusters around St Etheldreda’s Church and the gates of Hatfield House, where the Tudor Old Palace was Elizabeth I’s childhood home.
The post-war new town grew beside it, and today Hatfield is a university town with a large business park, offices and retail along the A1(M), and a steady flow of new apartments and student accommodation.
Commercial interiors, new-build flats and the town’s homes keep us busy here.

Showers and baths resealed after a full strip-out.
Commercial washrooms, finished properly
Trough basins, vanity tops and terrazzo floors all meet walls somewhere, and every junction needs a hygienic, mould-resistant sealant that can be cleaned easily. We match the colour to the finishes so the joints don’t distract from the design.
- Hygienic, mould-resistant sanitary silicone
- Colour matched to tiles, tops or grout
- Out-of-hours working can be arranged
- RAMS on request

Metal cladding columns and panels
On new apartment and office blocks, metal cladding columns and panels meet glazing and brick. Those joints move, so we seal them with low-modulus, weather-resistant products in a colour matched to the cladding.
Our façade and curtain wall page has more.
