What sets our bay & bow windows apart in Hatfield.
Structural Corner Posts
Steel-reinforced bay posts carry the load above — essential for 45° splayed bays and box bays that support first-floor masonry.
3-, 4- & 5-Facet
Splayed bays for Victorian terraces, box bays for Edwardian semis and shallow bows for cottages — all built to your survey template.
Lead-Lined Roofs
Traditional lead-flashed or GRP roofs matched to the existing bay, with proper flashing back to the brickwork and stepped over the parapet where required.
Replacement in a Day
In most cases we remove the tired 60s or 70s bay and refit the replacement inside a single working day — no exposed brickwork overnight.
Heritage or Modern
Traditional splayed bays with astragal bars and dummy sashes, or clean contemporary square bays in aluminium — matched to the age of the property.
Kerb Appeal
The single most valuable retrofit for a Victorian or Edwardian terrace — a restored bay adds visible property value and lifts the entire façade.
What Hatfield homeowners tell us.
"A proper trade. Every promise kept — from the timescale to the finish. We've since recommended them to three neighbours."
"Slim aluminium sashes in anthracite grey — exactly the balance of period feel and modern lines we wanted. Conservation area approved."
"Punctual, quiet, tidy, honest. Three years on the front door still closes with that satisfying thud, and the paint finish hasn't moved."

- What thermal performance does bay & bow windows achieve in Hatfield?

- Do I need Building Regs approval for a bay replacement?
- A like-for-like replacement on an existing bay is covered under CERTASS. If we're modifying the structural opening or replacing the roof, we may need to notify Building Control — we handle the paperwork either way.
- Will the bay stay up while you replace it?
- Yes — we prop the load above with acrow supports before removing the original frame, then install the new structural posts and transfer the load. The brickwork above is never unsupported.
