First-Year Maintenance Planning Checklist

Note where fine cracking appears at junctions between new and existing work, marking the location and the date you first saw it.

A dated first sighting is what later makes it possible to tell a stable crack apart from one that is still changing.

Do not draw a conclusion from what you have recorded. Show the dated observations to a qualified professional and let them say what they mean.

Photograph anything you notice with something in shot for scale, such as a coin or a pencil, so that a later photograph can be compared against it.

Without a scale reference, two photographs taken at different points are almost impossible to compare usefully.

Look at the same locations again after the space has been through a full change in conditions, rather than checking them constantly.

Frequent checking makes ordinary variation feel like change, while spaced checks show whether anything is actually moving.

Note where doors and windows begin to catch or ease, since fit often changes as a building dries out and settles into use.

Changes in fit are among the clearest early signs of movement and are usually put down to poor adjustment instead.

Write down which areas the trades described as likely to show movement, so that what you see can be compared with what was expected.

Comparing observation against what the trades anticipated is far more useful than either of those on its own.

Keep a single list of movement observations rather than separate notes for each room, so that a pattern across the property can be seen.

Patterns across a building stay invisible while each observation lives in a different place.

Note where condensation forms during the first genuinely cold conditions, including which rooms, which surfaces and at what point in the day.

Condensation patterns are highly specific and are among the most useful things an owner can record about a new space.

Check whether any room heats or cools very differently from the rest, and record it while the conditions that revealed it are still present.

Temperature differences are obvious during a cold spell and completely invisible once conditions moderate again.

Ask the installer to explain any behaviour you did not expect from the heating system before you start adjusting settings yourself.

Systems often behave unexpectedly on first use in ways that are entirely normal, and adjustment can make matters worse.

Heating, ventilation and any fuel-burning appliance stay with qualified professionals. Report what you observe rather than altering the installation.

Note whether draughts appear at particular positions and whether they coincide with junctions in the new work.

Draughts felt in cold conditions are much easier to describe accurately at the moment they are noticed.

Write down what you changed in the settings and when, so a later conversation is not a guess about how the system was being run.

Owner adjustments are the first thing an installer asks about and the last thing anybody has actually written down.

Note which rooms feel persistently humid and whether that changes as the space is used, without treating any observation as a diagnosis.

Construction moisture leaves a building unevenly, and where it shows varies considerably from room to room.

Record how you are actually ventilating each room while moisture is still leaving the building, rather than how you intended to ventilate it.

Owners rarely remember how a space was being used during its earliest period, which is exactly what makes a damp observation hard to interpret.

Check whether decorating left until later depends on the building drying first, and record what you were told about that.

Decorating over work that is still drying is a common cause of finishes failing shortly after they have been applied.

When a surface is ready to decorate depends on the material and the conditions. Ask the installer or a qualified decorator rather than judging by appearance.

Note where salts, staining or patchy drying appear on new plaster or masonry, with dates, rather than acting on any of it.

Drying patterns change considerably over the early life of new work and look alarming at particular stages.

Record whether any window, vent or extract was described as needing to be left in a particular position while the work dries.

Instructions about ventilation given at handover are almost never written down and are forgotten almost immediately.

Note how water actually behaves on new external surfaces during heavy rain, including where it collects and where it runs away.

Water behaviour can only be observed in real conditions and is the most useful outdoor observation an owner can make.

Check whether outlets, channels and gullies still clear as expected once leaves and debris arrive with the season.

Drainage that works perfectly on a clear day behaves quite differently once the first fall of leaves arrives.

Do not attempt to clear or alter anything at height or below ground. Report what you observe to a qualified professional in the relevant trade.

Photograph external surfaces before their first hard weather, so that any change afterwards has something to be compared against.

The absence of an early photograph is the usual reason a later change cannot be described convincingly to anybody.

Note where efflorescence, colour change or uneven weathering appears on masonry and paving, without treating any of it as a fault.

New external materials weather unevenly at first, and much of what appears early settles down on its own.

Check whether joints, pointing and sealed junctions look the same after the first freezing conditions as they did beforehand.

The first freeze is when external work reveals whether anything is holding water where it should not be.

Record what the trades said to expect outdoors, so that ordinary weathering is not reported to them as damage.

Owners frequently raise ordinary weathering and miss the change that mattered, for want of any reference point.

Note which doors, drawers and windows need more effort than the others once the space has been in daily use, and where each one is.

Adjustment needs only show up after repeated use, and they are far easier to raise as one list than individually.

Check whether catches, seals and closers behave the same in cold conditions as they did on the day of handover.

Seals and closers commonly behave differently once temperatures change, which is normal for many fittings.

Ask whether adjustment after a period of use is expected, and who would carry it out, before adjusting anything yourself.

Owner adjustment of fittings frequently disturbs how they were originally set up and complicates a later visit.

Adjustment of glazing, doors and any fitting affecting weathertightness belongs with a qualified installer rather than the owner.

Note anything that has begun to make a noise it did not make at first, describing the sound plainly rather than guessing at its cause.

A plain description of a sound is far more useful to an installer than an owner theory about what is producing it.

Record which items you have already adjusted or lubricated yourself, so that nobody later assumes the installation is untouched.

Undisclosed owner adjustments are a common source of confusion when somebody returns to look at a fitting.

Keep every observation in one place with a date and a location, however trivial the item seems at the moment you notice it.

Trivial observations become meaningful only when several of them line up, which requires them to be in the same list.

Describe the conditions alongside the observation, such as heavy rain or the first cold night, since the conditions are half the information.

An observation without its conditions cannot be compared with anything and is difficult for anybody to act on.

Photograph from the same position each time you revisit an item, rather than from wherever you happen to be standing.

Comparable photographs are the closest thing an owner has to a record of whether something is genuinely changing.

Note which observations you have already raised with somebody and what was said, so the same item is not reported twice as new.

Repeat reporting of the same item weakens the credibility of a list that may also contain something important.

Read back over the list as a whole from time to time, rather than only looking at it when something new appears.

Reading the whole list at once is what reveals a pattern that no single observation would ever have suggested.

Gather the upkeep tasks you were told about into a single list, rather than leaving them spread across manuals, messages and notes.

Tasks spread across separate documents are effectively invisible and rarely get carried out at all.

Note which tasks depend on conditions and which can be done at any point, so the seasonal ones are not missed by default.

Condition-dependent tasks have a natural moment, and missing it usually means waiting for the same conditions to return.

Decide which tasks you will carry out and which you will pass to a qualified trade, and write that split down plainly.

An undecided task tends to sit undone, with each party assuming the other regards it as theirs to handle.

Where a task touches gas, electrical work, height or a sealed system, it belongs with a qualified professional however simple it looks.

Check whether any task has to happen before another, such as clearing a surface before a treatment can be applied to it.

Sequence matters for several common tasks, and doing them in the wrong order wastes the effort entirely.

Note what each task needs in the way of materials or equipment, and whether you actually have any of it to hand.

Tasks fail at the point of missing equipment far more often than at the point of missing willingness.

Record when each task was last carried out, starting from the first time you do it, so that everything afterwards has a reference point.

The first recorded date is what turns a list of intentions into something that can actually be tracked.

Separate your observations into those you want to raise now and those you are simply monitoring, and mark the difference plainly.

Raising everything at once dilutes the items that matter, while raising nothing at all loses the moment entirely.

Ask whether anything you are monitoring would be better raised early, since some things are far easier to address before they develop.

Installers usually know which items get harder to put right with time and which genuinely settle on their own.

Check whether any aftercare arrangement expects problems to be reported promptly, and record what you are told about that.

Waiting to see whether something settles can sit awkwardly with an expectation that issues are reported when first noticed.

How promptly something must be reported depends on the arrangement. Ask the issuing party to confirm their position in writing.

Note what you would need to show if you raised an item later, and start collecting it now rather than afterwards.

Evidence gathered while something develops is far stronger than evidence assembled once it has already been raised.

Write down your reasoning whenever you decide to wait, so the decision remains a choice you can revisit rather than a drift.

Recorded reasoning lets you revisit a decision honestly instead of rediscovering the item much later by accident.
