External Maintenance Planning Checklist

Walk right round the outside and list every material you can see, including trims, fittings and boundary structures, rather than thinking of the building as walls and a roof.

Upkeep is decided by materials rather than by elevations, and small items such as trims and fixings are where problems usually start.

Ask the contractor which external elements were expected to be maintained over time and which were chosen precisely so they could be left alone.

What a material needs is a manufacturer and trade matter; ask the supplier or a qualified trade rather than applying one material's routine to another.

Note where a material has been used in an unusually exposed position, such as close to the ground, under a discharge point or where it is regularly wetted.

The same material in a sheltered and an exposed position asks for quite different attention, and the difference is visible from the ground.

Write down which external elements you understand to be structural, which are protective and which are decorative, and say plainly where you are not sure.

Whether an external element plays a structural role is a question for a qualified professional; never assume from how something looks.

Record which parts of the outside were not touched by the works at all, since they carry on ageing on their own account and are easily left out of a plan built round new work.

A maintenance plan assembled at handover tends to describe only what was just built, which is the part least likely to need anything soon.

Note anything on the outside likely to be affected by how the property is actually used, such as a route people walk, a place bins stand or where a vehicle is parked.

Wear from everyday use is concentrated in a few small places and is usually left out of any list built by looking at materials alone.

Note which parts of the building could only be reached from scaffold or a platform during the works, since the same parts will need the same access every time thereafter.

Owners frequently discover that a small task on a high element is a substantial arrangement rather than an afternoon.

Write down what has been built, planted or paved since that would now make bringing access equipment in harder than it was during the works.

The finished landscaping is usually the thing that turns a straightforward access route into an awkward one.

Describe the route to the rear and sides in ordinary terms, including whether somebody carrying equipment could pass a bin store, a gate or a narrow side return.

Whoever is asked to reach a high element will want to know about this route first, and a plain description saves a wasted visit.

Ask whether any element was designed to be reached from a particular position, such as glazing intended to be cleaned from inside the building.

Where that was part of the design it is rarely written down anywhere, and it stops being obvious once the fitters have gone.

Note where reaching part of your building would mean standing on, or placing equipment on, land that belongs to somebody else.

Access over land belonging to another party is a legal matter; take it to your own legal adviser and to the neighbour long before it is needed.

Ask whether there is anywhere equipment should not be set up, such as over a drainage run, a light well or a newly laid surface, and write down what you are told.

Where access equipment may stand is for whoever supplies it and for a qualified professional to determine; do not judge it from appearance.

Ask which external finishes were applied on the understanding that they would be renewed at some point, and which were never intended to be recoated at all.

Overcoating something that was never meant to be coated is a common and damaging mistake, and it is nearly always made in good faith.

Note what a renewal is expected to involve, since some finishes are simply gone over again while others must be taken back to the surface underneath first.

How a coating is renewed is a manufacturer instruction; ask the supplier what is required rather than repeating what was done to a different material.

Record which elevation each coated element is on, because the face that takes the weather usually reaches the point of renewal well before the sheltered ones do.

Treating all elevations at once wastes effort on some and leaves others too late, and the record is what allows them to be separated.

Note whether each external finish was applied at the property or arrived already applied, since the two are renewed in very different ways and by different people.

Factory-applied finishes usually involve the supplier rather than a local trade, and that is worth knowing before anybody is asked to look at one.

Record where sealant has been used externally and ask what renewing it involves, since sealed joints are among the first external elements to ask for attention.

External sealant selection depends on the materials either side of the joint; ask the supplier or a qualified trade rather than choosing by colour.

Ask whether any external finish should be renewed before it has visibly failed, and how somebody standing at ground level would know it was getting close.

When a coating needs renewing is a judgement for the material supplier or a qualified trade; ask them rather than waiting for a visible failure.

Note what the gutters, downpipes and their fittings are made of, since the material decides how they are cleared, joined and repaired when something fails.

The repair route for one gutter material has nothing in common with another, and it is the first thing a trade will ask about.

Record where each downpipe discharges and into what, following it as far as you can see from the ground and noting where it disappears.

The point at which a route goes out of sight is where owners lose track of it, and where blockages tend to sit unnoticed.

Write down where a rainwater route runs behind or over something that would have to be moved to reach it, such as a store, a fence or a planted bed.

Anything requiring dismantling before it can be cleared tends to go uncleared until there is a visible problem.

Note how the ground sits against the wall and where it has been raised by new paving, gravel or planting beds since the works were finished.

Ground levels against a wall affect how a building behaves and are a matter for a qualified professional; record what you see rather than adding or removing material.

Record where surface water runs across paved areas during rain and which way each laid surface appears to shed water, noting anywhere it runs back towards the building.

Paving is easy to observe in the rain and is one of the few external things an owner can genuinely see for themselves.

Ask what should happen if a drainage route blocks and who you would need to contact, before you find yourself working it out during heavy rain.

Responsibility for a drainage run may not be entirely yours; confirm locally with the relevant authority or provider which part belongs to whom.

Write down which boundary structures you believe are yours to maintain, then check that belief against your deeds rather than against local habit.

Ownership of a boundary is a legal matter; confirm it with your own legal adviser rather than relying on which side the posts happen to be on.

Note where an external element is shared with a neighbour, including walls, fences, a common gutter, a shared paved route or a joint drainage run.

Shared elements frequently carry obligations on both sides; take the position to your own legal adviser before arranging work on one.

Record which parts of your own building can only be maintained from a neighbour's side, and how that was handled the last time anybody needed to.

This is much easier to discuss before it is urgent, and it decides whether some elements are practically maintainable at all.

Note anything on a neighbouring property that overhangs, drains onto or grows into yours, and keep a dated record of it rather than only a memory.

These situations develop slowly, and a dated record is the difference between a conversation and a disagreement.

Write down who you would speak to on each side and confirm you have a current way of reaching them, rather than assuming the person you met still lives there.

Contact details for neighbours go out of date quietly, and the moment you need them is rarely a convenient one.

Ask what local restrictions could apply to changing the appearance of the outside of this building, and confirm the position before planning any renewal.

Restrictions on external appearance vary by location and by property; confirm what applies with the relevant local authority before anything is arranged.

Note which materials were chosen partly because they were expected to need less attention, and ask what they still need rather than assuming the answer is nothing.

Materials described as low maintenance usually still want cleaning, clearing or occasional attention at their fixings.

Ask what happens when a low-upkeep material is damaged, since some are easy to live with day to day and awkward to repair invisibly.

Ease of upkeep and ease of repair are separate questions, and owners tend to hear only the first.

Record whether any external material was expected to weather to a different appearance, and whether that change was intended by the design.

Deliberate weathering is often mistaken for failure by a later owner who was never told it was the point.

Note where two external materials meet that will age at different rates, since the junction between them usually shows before either surface does.

A junction has to take up the movement of both materials as well as the water running over it, which is usually more than either surface has to cope with.

Write down what cleaning method the supplier of each external surface considers acceptable, against the element rather than as a general note.

Cleaning methods differ sharply between materials and washing under pressure damages some of them; ask the supplier before anything is used.

Ask which external elements are expected to be replaced rather than maintained, and what replacing one would involve in terms of access and disruption.

Knowing that something is a replacement item changes how you treat it and what you keep by way of spares and records.

Set the plan out element by element rather than by time of year, so each material carries its own note of what it needs and who told you that.

Element-based notes survive changes of ownership and habit, while a routine arranged only by season loses its reasoning.

Name each element so that somebody standing outside could identify it without you there, using elevations and fixed features rather than household shorthand.

Instructions describing the bit above the back door stop working as soon as anything about the building changes.

Attach a photograph of each external element as it was when newly finished, since a plan with no starting point cannot show that anything has changed.

The new-condition photograph is easy to take at handover and impossible to obtain afterwards.

Record against each element who told you what it needs, so that advice received later can be weighed against what the original supplier or trade said.

External upkeep attracts a great deal of confident advice, and knowing the source of the original position is the only way to sort it.

Keep the items that need somebody qualified visibly separate from those that are simply a matter of looking, rather than mixing them in one list.

Some external work can only be carried out by particular trades or registered people; confirm what applies where the property is before arranging anything.

Add to the plan whenever an external element is renewed or replaced, recording what was actually used rather than leaving the earlier description in place.

An external plan describing materials that are no longer there is trusted right up to the point where it misleads somebody.
