What sets our sash windows apart in Buckingham.
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.
What Buckingham homeowners tell us.

"Heritage flush casements across the whole cottage. From the road you'd swear they were painted timber — but with modern thermal performance."
"The orangery has become the heart of the house. Warm in January, cool in July. Every trade on site was courteous and clean."
Common questions from Buckingham homeowners.
- Do you install sash windows in Buckingham?
- Yes — South East Windows & Doors installs sash windows across Buckingham (MK18) and the wider Buckinghamshire area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does sash windows installation take in Buckingham?
- Most Buckingham 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 Buckingham?
- Many of our Buckinghamshire projects sit within the Chilterns AONB or conservation areas. Our heritage flush casements and timber-effect finishes are frequently accepted where UPVC once wasn't. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Buckingham projects that require them.
- What guarantee covers sash windows in Buckingham?
- Every sash windows installation in Buckingham 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 Buckingham?
- Yes — we can share recent sash windows case studies from across Buckinghamshire, including projects in Market Hill, Maids Moreton and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does sash windows achieve in Buckingham?
- Energy-efficient sash windows installed across Buckingham, Buckinghamshire 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.
