The maintenance records that help you sell your home (and the ones nobody asks for)

Every buyer, and every inspector or surveyor they hire, is asking one question about each major system: how much life is left, and has it been looked after? They can estimate the first from the age. They can only know the second from records. An inspection sees the furnace on one afternoon; a service record shows it has been checked every year for a decade, which is a far stronger signal that it will keep running.

Records also shift the negotiation. When a buyer’s inspector flags a 15-year-old water heater, a seller with the receipt showing it was flushed annually and the anode replaced can argue it has years left. A seller with nothing accepts the price reduction. The records do not have to be elaborate. They have to be dated, specific, and findable.

• Heating and cooling service records. The annual furnace, boiler, heat pump or air-conditioner service. In the UK, the boiler’s Gas Safety Record or service certificate. These are the single most requested documents in a sale.
• Replacement dates and receipts for major systems. Roof, furnace or boiler, water heater, air conditioner, windows, electrical panel or consumer unit, septic tank work. The receipt fixes both the date and the installer, which matters for transferable warranties.
• Warranties and manuals. Especially anything transferable: roofing, windows, HVAC compressors and heat exchangers, appliances under extended cover. Register them; an unregistered warranty is often void.
• Safety and compliance certificates. UK: EICR and Gas Safety Record. Australia: compliance certificates for electrical, gas and plumbing work, and the pest inspection report. US and Canada: permits and final inspections for any work that needed them; unpermitted work is a common deal-breaker.
• A maintenance log. Dated entries for the recurring work: filters, gutters, chimney, dryer vent, softener, flush, alarms. Nobody reads every line, but a log that runs back years is the single clearest evidence of a cared-for home.
• Photos of hidden work. Before the drywall went back on, before the deck boards went down, when the drainage was dug. Ten photos on your phone answer questions an inspector cannot.

Paint colours, the receipt for the lawnmower, the light bulbs you bought, cleaning products, minor consumables. A buyer does not care and an inspector will not look. Keeping them is harmless but it buries the useful records in noise, and it is usually why people give up on record-keeping altogether. If a document does not answer "how old is it, who did it, and was it maintained" about a system that costs four figures to replace, it can go.

1. Capture at the moment of doing. When the technician leaves, photograph the invoice. When you change a filter, log it. The record is worthless if it depends on remembering later.
2. One place, searchable. A folder per system on your phone or cloud drive works. An app that links each record to the equipment and the task works better, because "when was the boiler last serviced" becomes a lookup rather than a search.
3. Record cost as well as date. It is what turns a log into a spending history, which is what the next section is about.
4. Photograph every data plate once. Brand, model, serial, and the install date decoded from the serial. This is the inventory a buyer’s inspector will build anyway; having it ready makes you look organised and saves them an hour, which buyers notice.
5. Export a summary once a year and keep it with your house documents, so the history survives a lost phone or a changed app.

The value of records is only realised if they can be shown. A drawer of receipts is honest but unpersuasive. What works is a short, clean document: the home, its major systems with ages and warranty status, the recurring maintenance with dates, and the spending by category. Agents in all four countries increasingly ask sellers for exactly this, and some produce their own version for listing packs.

Maintainly Pro’s Home Report generates that document from the log you already keep in the app: a maintenance score, equipment with serials and warranty dates, dated history with costs and notes, and spending by category, as a PDF you can attach to a listing, hand to a surveyor or send to an insurer after a claim. Free users can generate one sample to see what theirs would look like.

The second party who wants your records is the insurer, and they want them at the worst moment: after a claim. Escape-of-water and fire claims routinely turn on whether the homeowner maintained the system that failed. A boiler service history, a dryer vent cleaning log or a record of the annual roof inspection is the difference between a paid claim and a dispute about neglect. Keep the log for the sale you may make in ten years, and for the claim you may need next winter.
