What sets our sash windows apart in Corby.
Authentic Period Proportions
Deep bottom rails, run-through sash horns, ovolo detailing and single or two-over-two astragal bars — proportioned from measured drawings of original Georgian and Victorian sashes.
Spring-Balanced Movement
Modern spiral-spring balances replace the traditional cord-and-weight — no rattle, no rot, and the sash stays where you put it for 25+ years.
Tilt-In for Cleaning
Both sashes tilt inward on release catches so the outside of the glass can be cleaned from inside — a necessity in London terraces without rear access.
Heritage Colours
Painswick, Chartwell Green, Cream, Anthracite Grey and Irish Oak in deep-grain foil finishes — colour-fast for 25+ years with no maintenance.
Conservation-Area Approved
Regularly accepted by conservation officers across London and the Home Counties. We prepare drawings and finish samples for your planning officer at no charge.
A+ Modern Performance
Argon-filled A+ glazing, warm-edge spacer bars and PAS 24 security locking — Georgian looks, 21st-century thermal and security performance.

Common questions from Corby homeowners.
- Do you install sash windows in Corby?
- Yes — South East Windows & Doors installs sash windows across Corby (NN17, NN18) and the wider Northamptonshire area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does sash windows installation take in Corby?
- Most Corby projects run to a two-to-eight week lead time from signed quote to install, depending on manufacture. Once on site, a typical sash windows install completes in one to five working days with full dust-sheet protection and clean-down.
- Do you handle conservation-area planning in Corby?
- Northamptonshire's ironstone villages need windows that respect the building — deep reveals, heritage colours, subtle profiles. Our flush casements and painted composite doors have been accepted throughout the county's conservation areas. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Corby projects that require them.
- What guarantee covers sash windows in Corby?
- Every sash windows installation in Corby is covered by our insurance-backed 10-year guarantee — parts, labour and finish. Aftercare is direct with the installing team, not a call centre.
- Can I see recent sash windows work near Corby?
- Yes — we can share recent sash windows case studies from across Northamptonshire, including projects in Priors Hall, Great Oakley and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does sash windows achieve in Corby?
- Energy-efficient sash windows installed across Corby, Northamptonshire achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- Will a uPVC sash window be accepted in a conservation area?
- Often, yes — particularly with a timber-effect finish, deep bottom rails, run-through horns and through-frame astragal bars. Success depends on the specific conservation area and officer. We prepare drawings and finish samples at no charge to support planning applications.
- Are they suitable for listed buildings?
- Sometimes — listed-building consent is at the officer's discretion. Where uPVC is refused, we can supply the same profile in painted aluminium or timber-composite. We advise honestly at survey.
- How authentic do modern sash windows look?
- Very. At three paces you would not know — the giveaway on poorly detailed sash windows is thin bottom rails, missing horns and applied (rather than through-frame) glazing bars. We specify all three correctly as standard.
