After the handover: protecting design intent once the client moves in

The snag list is closed. The photography is done. The client has moved in, and the project has moved into the part of its life that nobody photographs.

What happens over the following year decides how the work is remembered — by the client, by their visitors, and in the anecdote they tell when someone asks who did it. Very little of it is within the designer's control by then, which is precisely why the groundwork has to be laid before that point.

What usually goes wrong

Not defects. Ordinary use meeting a surface nobody explained.

The patterns repeat with striking consistency:

The marble island. Specified honed, selected carefully, correct for the scheme. Within six months it carries a constellation of dull marks. The client concludes the stone was wrong. In fact it etched, which is what marble does, and nobody told them that citrus and many household cleaners would do it.

The first professional clean. A cleaning company arrives with general-purpose products. Several are mildly acidic, several are abrasive, and some strip sealer. One visit can undo a specification decision that took three meetings to make.

The timber that moved. Solid timber in a room with underfloor heating, or against a west-facing wall, or delivered in one season and lived in through another. Joints open. The client reads it as poor workmanship rather than as material behaviour that needed managing.

The well-meant online purchase. Something bought to protect a surface, applied enthusiastically, and now producing a haze that is considerably harder to remove than it was to apply.

None of these are failures of design. All of them reflect on the designer.

The handover pack does more than any product

The single highest-leverage intervention is documentation, and it costs almost nothing.

A finishes section in the handover pack should name, for each significant surface:

• The specific material. Not "marble" — the stone name. Not "oak" — whether it is solid, veneered, and what the finish is.
• The finish. Honed, polished, matte lacquer, oiled, brushed.
• What has been applied, and when. Sealer product and date, at minimum. This is the detail most often missing and most often needed.
• Cleaning: what is safe, and explicitly what is not. The prohibitions matter more than the recommendations, because the damage comes from the prohibited list.
• Who to contact for refinishing or repair.

Most of this information exists already — it is in the specification, the supplier documentation and someone's email. The work is collation, not investigation. And it is the difference between a client who manages a surface and one who discovers it.

Brief the cleaner, not only the client

The person who will touch these surfaces most often is rarely in the handover meeting.

Housekeeping staff and cleaning contractors change, and they bring their own products. A one-page sheet that can live in a cupboard — what to use, what never to use, which surfaces need particular care — survives staff turnover in a way a conversation does not.

Where a client retains a cleaning company, it is worth the conversation happening directly. The instruction "pH-neutral only on the stone, nothing abrasive, no vinegar or citrus products anywhere" prevents a large proportion of what we are later asked to correct.

Protection decisions belong at design stage

Where a protective treatment is appropriate, earlier is better — and not for commercial reasons.

Edge profiles constrain what is possible. A shaped or bevelled edge presents a different proposition from a square one. Finish governs how a film reads: what disappears on one surface can be visible on another. And material compatibility is not uniform across everything that gets called stone.

Decide after installation and you are working within whatever was built. Decide during specification and the specification can accommodate it — or you can establish early that protection is not appropriate here, and design accordingly.

The corollary matters too: there are surfaces where the right answer is no treatment at all. A recommendation that can only ever be "yes, apply something" is not a recommendation. Sometimes the correct advice is a cleaning regime and a realistic conversation about patina.

Have the patina conversation early

This is the awkward one, and it saves the most grief.

Some clients read a softened, marked marble surface as evidence of a life well lived. Others find a single etch genuinely distressing. Both are legitimate. But the two require different specifications, and the difference only becomes visible after installation unless somebody asks.

Ask during material selection: how will you feel when this surface no longer looks new? If the answer is discomfort, that is useful information, and it may point toward a different material, a different finish, or a protection strategy agreed upfront rather than retrofitted in a panic.

What we can do alongside a design team

We assess material, sealant, finish and use, and recommend accordingly — including recommending nothing where that is right.

In practice that can happen before handover, so findings and aftercare guidance become part of the client's handover pack rather than something they go looking for in year two. The record of what was assessed and agreed stays with the property, which means a future cleaner, contractor or owner is working from facts.

The consumer relationship stays yours where you want it to. We are comfortable working in the background of a project, and equally comfortable being introduced directly — whichever suits how you run client relationships.

If you have a project approaching completion, the useful things to share are the surfaces involved, their materials and finishes, and the handover date. If a project completed some time ago and something is now going wrong, that is worth a conversation too — and it is more common than anyone admits at industry events.
