Roof Windows — Quarrendon
Local Roof Windows Specialists for Quarrendon
Quarrendon is a mixed-era residential area north-west of Aylesbury town centre, combining mid-1950s council housing — built in the same post-war expansion as Southcourt — with 1960s and 1970s private development on the outer streets. The result is a wider range of roofing conditions than a single-era estate: the oldest Quarrendon Lane properties share Southcourt's original-felt problem, while the Kingswood Road and Coldharbour Way 1970s stock shares Bedgrove's nail sickness timeline.
Quarrendon occupies flat to gently rising ground north-west of the town centre on Vale clay. The northern and western edges of the development have slightly more open exposure than the sheltered inner streets — the properties facing open farmland on Quarrendon Lane and Coldharbour Way see marginally higher wind loading than the more enclosed central streets.

Roof Windows in Quarrendon — What Makes It Different
Roof window installations across Quarrendon follow the same permitted development framework as the rest of Aylesbury — rear slope windows in standard sizes are generally permitted development. The variable is rafter sizing on the older 1950s properties, where pre-standard rafter dimensions should be confirmed before ordering.
What We Find in Quarrendon
On 1950s Quarrendon properties, the specific survey finding that can affect roof window installation: original battens at shallower depth than current standards (22–25mm rather than 38mm), which means roof nail sickness and batten replacement may be appropriate before installing a Velux that will be in place for 30+ years.
Our Approach to Roof Windows in Quarrendon
Survey first on all Quarrendon roof window installations. Rafter and batten condition confirmed before ordering. On older properties, we advise if a batten upgrade during the installation makes long-term sense — the scaffold is already up and the cost differential is modest.
How We Work
The Roof Windows Process in Quarrendon
Survey and planning check.We measure rafter spacing, confirm roof pitch, and advise on the correct Velux size and flashing type. We check whether installation is permitted development or requires planning permission — this varies by property location, elevation, and conservation area status.
Structural assessment.Standard Velux installation requires opening between two rafters and trimming the top and bottom. We confirm rafter depth and spacing before ordering. Non-standard rafter spacing requires a structural trimmer — we identify this at survey, not on installation day.
Supply and installation.Window supplied, opening formed, rafters trimmed, insulated reveal formed internally. Velux EDW or standard flashing kit installed and dressed into the surrounding tile. Internal boarding completed. Most standard installations take four to six hours.
Weatherproofing test.We test the flashing seal before leaving — running water over the junction and checking the internal reveal for any ingress. Open and close operation checked. Internal and external completion signed off.
Dual guarantee.Velux 10-year product warranty plus our 10-year installation workmanship guarantee. Both issued in writing.
Every job starts with a free survey. Call 0129 670 6028 to book yours.

A roof window is a straightforward upgrade done right. Here is what to consider before fitting one.
A dark loft, landing or extension that needs natural light
An existing roof window that leaks around the flashing
A loft conversion needing light and ventilation
A tired or fogged old skylight due for replacement
A room that would benefit from overhead rather than wall light
When it is not the answer: If your rafter spacing or a conservation-area position makes a standard install impractical, we will say so at survey rather than forcing an installation that will not sit right. Read the full guide.

Good to know
What It Is Like While We Work
A few hours of work with some internal dust around the opening; we sheet up and clean down. You do not need to stay home for external work - we just need power and access agreed in advance.
Installations run year-round; the opening is kept weathertight at every stage. Sitting on higher, more open ground to the north-west, Quarrendon's gable ends take the prevailing wind most directly.
