Serving Tunbridge Wells, Tonbridge, Pembury, Southborough, Paddock Wood & surrounding TN postcode towns
Most UK homes built or re-glazed before background ventilation became standard now fail the same checks — and tenants, landlords and assessors all ask the same thing: “why is the window misting up?”
Water running down the inside of the glass means humidity has nowhere to go. Without background ventilation it stays in the room — and on the walls.
You wipe it, it returns. The fix isn’t more bleach — it’s controlled airflow, which a trickle vent provides 24/7 without effort.
Assessors now penalise homes with no trickle vents. We resolve the flag without replacing windows or losing the period look.
Landlords have strict investigation and repair timelines. Our 10-working-day turnaround keeps you inside them, with an evidence pack for your records.
Modern double glazing seals too well. Without a trickle vent the room gets stale and humid, and sleep quality drops.
You almost certainly don’t need new windows. A retrofit vent gets you compliance for a fraction of the cost — typically from £50 per vent.
Real homes around Tunbridge Wells and the wider TN postcodes — vents retrofitted through the existing glass, frames left exactly as they were.
No competitor in the TN postcodes offers this. We don’t drill your frame or hack your windows about. We swap the sealed unit for a made-to-measure pane with a slim, controllable vent bar bonded to the top edge — so the frame, the look and the security all stay exactly as they are.
Two short visits. Ten working days from survey to clean-up. No drilling into the frame, no mess for tenants.
Our surveyor measures every opening, photographs the existing condensation and mould, and recommends the rooms that truly need a vent. Written report and clear quote within 24 hours — no obligation. — no obligation.
Your glass vents are manufactured to your exact pane sizes and delivered in around 10 working days. We don’t carry generic stock and force-fit it.
One short visit per property — usually a few hours. Vents fit with a new glass unit and the frame stays intact. The window is cleaned and a full photographic evidence pack is provided, if required.
The same compliance outcome — without the cost, mess or disruption of new windows.

The questions homeowners, landlords and agents ask before booking a survey.
No. The vent area is small (typically 4,000–8,000 mm² per window) and the airflow is too low to feel as a draught. Compared with the heat lost through chronic damp walls and mould-stained reveals, the trade is firmly in your favour.
Yes — that is exactly the job. Instead of cutting into the UPVC, we use glazed-in Glass Vents: we swap your existing glass for a new, slightly shorter unit with a slim ventilation bar bonded to the top edge. The whole assembly slots into your original frame — no drilling, frame intact, background ventilation aligned with EPC requirements.
For most replacement windows installed in England since June 2022, yes — Building Regulations Part F. For older existing windows there is no retrospective requirement, but landlords can be served improvement notices where lack of ventilation is causing damp and mould.
No. The vent body is integral to the unit and does not compromise the locking strip or the glass retention. Most have a closeable internal flap as well.
Usually yes for terraced houses and flats. Larger detached homes can run to two visits. We quote per window so you know the all-in cost up front.
Yes. Every job includes a photographic evidence pack and a written report you can forward to your landlord or attach to a management file — useful for damp/mould complaints, compliance audits and Awaab’s Law obligations.
