Lifting or Covering Over an Existing Floor Checklist

Write two lists for each room: what you actually know about the existing floor, and what you have assumed or been told without evidence.

Owners are usually surprised how short the first list is, and the length of the second is the real subject of this decision.

Against each thing you believe about the floor, note who told you and when, including a previous owner, an estate agent or a tradesperson.

Information about floors travels through several hands and is rarely checked, so knowing its source is part of knowing its value.

Look at any place where the existing floor is already visible in section — at a threshold, under a radiator, at a hatch, beside a pipe — and photograph it.

These accidental edges are the only free evidence available, and they frequently show more layers than anybody expected.

Note how the existing floor behaves underfoot — where it is soft, where it moves, where it creaks, where it feels hollow — room by room.

You are describing behaviour rather than diagnosing it, and this description is what a fitter or professional will want first.

Record any staining, lifting, curling, smell or cold patch in the existing floor, and photograph each one before deciding anything.

These observations are exactly the ones that make covering over unwise, and they are easy to miss once furniture is moved back.

Do not attempt to identify the cause of any of these. Ask a qualified professional to look before deciding whether to lift or cover.

Write down what you know about what is beneath the floor itself — a void, a solid base, a room below, pipework, wiring.

The lift-or-overlay decision is partly about whether that layer needs to be seen, so knowing what it is matters to the choice.

Ask the fitter how they would find out how many coverings are already down, and whether they can do that before the day work starts.

A small inspection opening beforehand changes the whole conversation from a guess into a decision based on evidence.

Ask whether there is a point at which the fitter would refuse to lay over what is already there, and what would tell them that.

Framing it as their professional judgement rather than your preference produces the most useful answer to this question.

Check each room separately rather than assuming the whole property is the same, since floors are usually done room by room over decades.

A hallway and a back bedroom frequently have entirely different histories, and one answer will not cover both.

Ask what adding another layer means for how the floor performs and for anybody who works on it in future.

Each layer added is a layer somebody eventually has to take up, and that cost falls to a later owner rather than to this project.

Ask what is likely to be holding the existing covering down, and what that would mean for lifting it if that were the route chosen.

How something is fixed decides how hard it is to remove, and it is one of the main reasons a lifting quotation varies.

If an opening is made to look, photograph what is found and keep the photographs with the decision record.

This photograph is the only evidence that will exist about the floor once a new covering goes over it.

If anything is found that cannot be identified, stop and ask an appropriately qualified professional before any further work, including further opening up.

Ask the fitter what each route does to the finished floor level in each room, and get the answer for both routes rather than only the one proposed.

Owners are rarely offered the comparison, and it is the piece of information the rest of the decision depends on.

Open and close every door in and out of each room and note the clearance under it, without measuring anything, and photograph the gap.

You are recording what is there so it can be discussed, and a photograph of a door bottom is enough to start that conversation.

Ask who takes off, trims and rehangs any door that no longer clears the floor, and whether that is inside the quotation.

Door adjustment is the classic item that falls between the fitter and the owner and is discovered at the end of the day.

Note what happens at the skirtings under each route, and whether the new covering goes under, against or over what is already there.

This detail decides how the finished room looks at every wall and is usually settled by the fitter without being raised.

Walk to every doorway and note what floor is in the adjoining room, and what the junction between the two would look like under each route.

A floor that becomes higher than the room next to it creates a step at the doorway, which is easy to foresee and hard to undo.

List anything in the room that meets the floor and cannot move — a kitchen unit, a fireplace, a built-in cupboard, a stair bottom, a radiator pipe.

Each one is a place where a raised floor has to be resolved somehow, and the list is much better made before than during.

Ask explicitly whether lifting the existing covering is inside the quotation, and ask the same question of every quotation you are comparing.

Two quotations can look very different simply because one includes this and the other assumes you have arranged it.

Ask who removes the old covering from the property, where it goes, and whether that is arranged by the fitter or by you.

Old flooring is bulky, heavy and awkward, and the disposal arrangement is regularly assumed rather than agreed.

Ask what lifting involves in terms of dust and noise, how long it lasts, and what protection is put over the rest of the property.

Lifting is usually much messier than laying, and households are rarely warned that the two stages differ so much.

Ask what usually has to be done to the base once the old covering is off, and whether that work is inside the quotation or priced separately.

The stage between lifting and laying is where most unexpected work appears, and knowing it exists is most of the preparation.

The condition of a base once it is exposed, and what it needs, is for a qualified professional to establish on site rather than something to agree in advance.

Establish who moves the furniture, at what point each room must be completely clear, and where the contents go.

Clearing rooms takes longer than anybody allows for and is almost never in the fitter's scope unless stated.

Ask how the two routes differ in how long the rooms are out of use, and what the household can do during each.

This is the practical difference the household actually experiences and it rarely appears in the conversation at all.

Agree in writing before work starts what happens if something unexpected is found: who stops, who is told, and how the decision to continue is recorded.

The moment a discovery is made is the worst possible moment to invent a process, and this agreement takes a paragraph.

Ask the fitter to name the things that would make them stop and ask for a qualified professional, and write that list down.

Their list will be better than yours, and having it in writing means neither party has to make a judgement under pressure.

Agree that anything found which nobody can identify means work pauses until an appropriately qualified professional has looked at it.

This one agreement covers a great many possibilities without requiring anybody to anticipate them in advance.

Never allow work to continue over, or to disturb further, any material that cannot be identified. Stop and ask an appropriately qualified professional.

Write down who you would contact if work had to stop, and have that contact before work begins rather than looking for it on the day.

Finding a professional while a room is open and a fitter is waiting is the worst possible circumstance to do it in.

Note what a pause would mean for the household, since rooms cleared and floors open are a difficult state to stay in for long.

Knowing this beforehand stops the pressure of the situation deciding the answer to a question that should be decided on evidence.

Keep your own dated note of what was found, what was said and who said it on the day the floor is opened.

This is the only continuous account of the work that belongs to you, and it costs a few lines.

Write down the reasons for covering over — programme, disruption, what is underneath, the condition of the base — rather than leaving it unstated.

A decision with its reasons recorded is one a later owner or professional can understand rather than guess at.

Record what you are choosing not to look at, and whether anything on your list of observations should be resolved first.

This is the cost of the choice, and naming it is what makes the choice informed rather than avoidant.

Ask what the existing covering contributes to the new build-up, and whether its condition affects how the new floor behaves.

Anything left in place becomes part of the floor, which means its condition is now part of the new floor's condition.

Ask what preparation the existing covering needs before anything is laid over it, and who is carrying that out.

Covering over is rarely as simple as laying on top, and the preparation stage is where the two routes converge in cost and effort.

Write down what has been left in place under the new floor, in which rooms, and keep that with the property records.

Whoever lifts this floor next will have no other way of knowing, and this note is the only thing that carries the information forward.

Ask what covering over means for whoever replaces the floor after this one, and note the answer alongside the decision.

Every decision to cover over defers work rather than removing it, and saying so plainly is part of taking it deliberately.

Write down which route has been chosen for each room, since a property does not have to be treated the same throughout.

Rooms differ, and a per-room decision is usually better than one applied to a whole property for consistency.

Confirm in writing what the chosen route includes — lifting, disposal, preparing the base, adjusting doors, moving furniture — item by item.

Each of these is a separate piece of work, and a written list is what stops any of them being assumed by both parties.

Record what you were told about the finished floor level and what that means for the doors and doorways in each room.

This is the thing most often described verbally and most often remembered differently by the two people in the conversation.

Keep the written agreement about what happens on a discovery with the rest of the record, where both parties can find it.

An agreement nobody can locate on the day is the same as no agreement at all.

Keep all the photographs of visible edges, thresholds, door gaps and anything you could not explain together with the written decision for each room.

Together these make a record of the floor as it was, which stops existing when the new covering goes down.

Tell everyone in the household what has been decided, what will be noisy, and when each room has to be clear and stay clear.

Floor work affects every room at once because of where the furniture goes, and that is easier arranged in advance.
