WINDOW SEEPAGE
Window Seepage: Very Common, but We Don't Have a Published Price Yet
Quick answer
Common fixes for window or aluminium-window seepage include re-sealing the frame perimeter, injection grouting at the frame-wall interface, sill repair, or window replacement (a related but separate trade). Rain ingress through windows is, like roofs and external walls, normally outside the Joint Office's scope. Note: we don't yet have reliable enough market pricing evidence to publish a responsible price range for this service — this page deliberately carries no headline figure. Actual pricing depends on an on-site assessment and may follow per-spot injection pricing or a separate frame-repair quote, depending on the cause.
When will the government act — and when won't it?
Like roofs and external walls, rain ingress through windows is explicitly on the Joint Office's published exclusion list — the government's official position is to advise owners to hire their own professionals.
Why isn't there a published price?
Window seepage has a wide range of causes — from ageing frame sealant (a relatively inexpensive fix) to a structural problem with the frame itself (which may need a full window replacement, a separate trade). Without enough reliable market pricing evidence, we won't give you a rough number that could mislead — that's part of what our transparent-pricing promise means: no evidence, no number. Actual pricing follows an on-site assessment and is quoted against whichever mechanism applies (per-spot injection pricing, or a separate window-trade quote).

Frequently asked questions
Why isn't there a price on this page?
Because window seepage causes and job scope vary too widely for us to publish a responsible range yet. We'd rather be upfront about the evidence gap than give you a misleading number. Send us a photo and a brief description on WhatsApp and we'll arrange an on-site assessment and quote.
Can the Joint Office handle window seepage?
Rain ingress through windows is normally outside the Joint Office's scope — the government's guidance is to hire your own professional.
Do I always need a full window replacement?
Not necessarily. Many cases are just ageing sealant around the frame, which re-sealing or injection grouting can fix. Only genuine structural damage to the frame itself usually calls for replacement — a separate window trade, which we can refer you to.
