Loft Condensation & Roof Ventilation FAQ for SL4
Will the repair last on a Windsor property?+
We spec to the local stock — like-for-like materials, proper mechanical fixings, code 4 or 5 lead at flashings — and back it with a written workmanship guarantee.
How far are you from Windsor?+
Our yard is in High Wycombe — about 11.9 miles, roughly 29 minutes off-peak via M4 Junction 6. That keeps travel charges down and return visits painless.
Will my insurer accept your Windsor report?+
Yes — we provide photo-documented reports with the cause, scope and quoted repair. We've done this for most major UK insurers on jobs around Windsor Castle.
Can you find the leak if it's not obvious?+
Almost always. We trace from inside (loft staining, daylight, damp lines) then verify outside. On SL4 roofs the entry point is often a metre or more from the visible stain.
What's your busiest time of year in Windsor?+
Autumn and early spring — after the first A308-corridor storms expose weak spots. Book SL4 surveys 2-4 weeks ahead during those windows.
