Bay & Bow Windows in Daventry, Northamptonshire
Every bay & bow windows project we deliver in Daventry starts with a senior surveyor on site — measuring, listening, and specifying to the character of Long Buckby, Braunston and the wider Northamptonshire area. 3-, 4- and 5-facet bay and bow window replacements with structural corner posts and lead-lined roofs.
Bay & Bow Windows designed around ironstone villages, deep reveals and heritage colours that satisfy conservation officers.
Daventry's town-centre stock and the surrounding canal-country villages — Braunston, Long Buckby, Weedon Bec — each need a different specification. We work throughout NN11 with planning-ready drawings where required.

What sets our bay & bow windows apart in Daventry.
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 thermal performance does bay & bow windows achieve in Daventry?
- Energy-efficient bay & bow windows installed across Daventry, Northamptonshire achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- 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.

- Usually yes if it's in good condition. Where the lead has failed or corroded we replace it with new milled lead in Code 4 or Code 5, or with a modern GRP roof for a longer service life.
