What the alternative costsNo priced alternative for condensation advice is listed in the supplied tool data.
If this goes wrong, you may spend time on ineffective changes while mould, damp or a failed sealed window unit continues to worsen.

Second choiceA chat interface, no skill needed, and roughly 30 minutes until you can act on the result.
How to actually do it
- Open a chatbot and paste the supplied prompt, completing the bracketed details with the rooms affected, window type, ventilation, heating, drying routine and visible symptoms.
- Add clear photos of the affected glass, frames, nearby walls and any vents if the chatbot accepts images, while removing people, addresses and other private details.
- Ask the chatbot to separate condensation on the room side of the glass from moisture between sealed panes, leaks and damp around the window.
- Open the relevant window and ventilation guidance from the manufacturer, your landlord or GOV.UK, then compare it with the proposed actions before changing vents, fans or heating.
- Carry out the safe household actions in the plan, such as using existing ventilation, keeping vents clear, reducing indoor moisture and wiping water from frames without blocking vents.
- Record which windows and rooms remain affected after the changes, then send the photos and observations to your landlord or a qualified window, ventilation or building professional if the problem persists or shows signs of a leak, failed sealed unit or building damp.
Prompt
Help me reduce condensation on my windows in the UK. Ask only the questions needed to distinguish ordinary indoor condensation from condensation between sealed panes, a leak, penetrating damp or a ventilation problem. Use the details below. Give me a prioritised plan of low-cost actions, including what to do with trickle vents, extractor fans, heating, drying clothes and wiping water away. Do not tell me to seal over or block ventilation. State which signs mean I should contact my landlord, a window repairer, a builder or another qualified professional. Do not diagnose mould or damp from text alone, and do not invent measurements, product specifications or legal rights. Separate actions I can do today from issues that need inspection. Details: property type: [house or flat]; tenure: [owner or private/social renter]; affected rooms: [rooms]; window type and age if known: [details]; where the water appears: [inside glass, between panes, frame, wall or ceiling]; ventilation: [trickle vents, extractor fans, mechanical ventilation or none]; heating and drying routine: [details]; visible mould, stains, peeling paint or leaks: [details]; photos or observations: [details].

Hand it to a person
The distant thirdA person who owns the outcome does this end to end, worth it when the failure is dear.
What it gets wrong
- AI cannot inspect whether moisture is on the room side of the glass, between sealed panes or coming through the building.
- AI cannot measure humidity, airflow or the condition of a window seal from a text description.
- AI cannot tell whether a visible stain is condensation mould, a leak or a wider damp problem without an inspection.
- AI cannot carry out repairs, improve extraction or establish whether a landlord or contractor is responsible for the defect.
- AI may suggest a general routine that does not suit the construction, occupancy or ventilation design of your home.
Even on a YES, the friction has a name: physical presence, judgement under ambiguity and context depth.

FAQ
- Can AI tell me why my windows are wet inside?
- It can help you work through common causes such as indoor moisture, poor ventilation, cold glass and drying clothes indoors. It cannot confirm the cause without seeing and sometimes measuring the window, surrounding wall and ventilation system.
- What can AI suggest for stopping condensation on windows?
- It can turn your household details into a practical routine covering ventilation, extractor fans, heating, moisture sources and wiping water from frames. Check the suggestions against your window and ventilation manufacturer guidance, and never block a vent to reduce draughts.
- Can AI tell if condensation means damp?
- It can list signs that need closer inspection, but it cannot diagnose damp from a description or photograph. Moisture between sealed panes, leaks, persistent stains, peeling paint or mould around the window should be checked by the appropriate landlord, window specialist or building professional.
- Should I call someone about condensation on my windows?
- Contact your landlord if you rent and the issue may involve the building, window or fixed ventilation, and contact a qualified window or building professional for failed sealed units, leaks or suspected building damp. AI can help you prepare observations and photos, but it cannot inspect or repair the problem.
