Storage Installation Questions Checklist

Ask the installer what they believe each wall is built from, and how they intend to establish what is behind it before anything is fixed.

The fixing method follows from the construction, and the construction is not always what it appears from the surface.

Establishing what a wall is built from, and what is safe to fix into it, is for a qualified professional to determine on site.

Tell the installer everything you know about cables and pipes in that wall, including sockets, switches, radiators and anything added since you moved in.

Owners often hold information nobody has asked for, such as where a previous run was chased in.

Look for any photographs taken during previous work that show the wall or floor opened up, and give copies to whoever is fixing anything.

A single photograph taken before plastering can settle a question that is otherwise guesswork.

If anything fixes down into the floor, ask what is beneath it, particularly where there is heating in the floor or services running through the void.

Floor fixings go wrong in a way that is difficult to put right and straightforward to ask about first.

Whether anything may be fixed into a floor, and what lies beneath it, must be established by a qualified professional before work begins.

If anything hangs from a ceiling, ask what it is being fixed to and who is confirming that, rather than accepting that it will be worked out on site.

Ceiling fixings depend entirely on what is above, which nobody can judge from below.

Write down any question that touches a structural element, and put it to a qualified professional before it becomes part of an installation conversation.

Keeping these questions separate stops an installer being asked to make a judgement outside their trade.

Any question about a structural element belongs with a qualified professional and must be settled before work is planned around it.

Note where walls, floors and ceilings are visibly out of square or bowed, and mention it in advance rather than leaving the installer to meet it.

Scribing to an irregular wall is normal work, but it is easier when it has been anticipated.

Note whether the floor slopes or dips where the run will stand, and ask how that is dealt with at the base of the units.

How the base is packed or scribed affects the appearance along the whole run.

Ask what happens to the skirting, architrave, picture rail and any pipe boxing where the storage meets them, and who removes or adapts them.

This is a common gap between trades, and it is usually noticed only once the work is finished.

Note the condition of the wall surface behind the proposed run, including any loose plaster, damp patch or previous repair.

What is behind a unit still matters, and a known problem should be dealt with before it is covered.

Damp, loose plaster or an unexplained repair should be assessed by a qualified professional before storage is fixed over it.

Note every socket, switch, vent and thermostat on the wall, and ask what happens to each one where the storage covers it.

Each of these is a separate decision, and each may involve someone other than the joiner.

Moving or covering any electrical accessory is a matter for a qualified electrician to advise on and carry out.

Ask who is responsible for taking the final measurements and when, and confirm that nothing is being ordered from a drawing alone.

Responsibility for measurement is worth stating plainly, because the consequence of an error falls somewhere.

Walk the route from the road to the room with a tape, and note the narrowest door, tightest turn and any stair with a low ceiling above it.

A finished unit that will not turn on a landing has to be dealt with on the doorstep, which is nobody's good option.

Ask whether the storage arrives assembled, flat or is made in the room, since each answer changes access, dust and how long the room is occupied.

The three approaches make entirely different demands on the house and on you.

Decide where components wait before installation, and note that they need somewhere dry, out of the way and out of the sun.

Materials left in a hall get knocked, and materials left in a damp garage can move before they are used.

Ask whether the materials need to stand in the room before they are installed, and what conditions the maker expects for that.

Some materials are expected to settle to the conditions of the room, and that has to be planned into the sequence.

Agree who looks at the delivery when it arrives and what happens if something is damaged or missing, before the vehicle leaves.

Damage noticed after the delivery has gone becomes a discussion rather than a straightforward replacement.

Ask who removes the packaging and offcuts, and where they go, since this fills a room quickly and is often assumed to be the owner's job.

Waste removal is a common gap in an arrangement and is easily agreed in advance.

Ask whether the flooring goes down before or after the storage, and record what each order means for the base detail and for future replacement.

This decision determines whether the floor can ever be lifted without dismantling the storage.

Ask when decorating happens relative to installation, and who makes good where the storage meets the wall and ceiling.

Making good is the classic gap between trades and is worth naming plainly before either of them starts.

Ask what electrical work has to happen before the storage goes in, and confirm that it is arranged rather than assumed.

Anything inside joinery has to be provided for while the wall is still open.

All electrical work must be carried out by a qualified electrician, who will confirm what applies where you live.

Ask whether other trades need access to the same room at the same time, and who is coordinating that rather than leaving it to chance.

Two trades in one room without a coordinator produces a hold up that nobody owns.

Ask what has to be cleared from the room before the installer arrives, and who moves anything heavy that cannot be lifted alone.

Rooms are rarely as empty as an installer expects, and this is agreed in a sentence beforehand.

Write down what each stage depends on, so that a change to one part is understood as a change to the others.

Sequences fail quietly when one element moves and nobody traces what else it touches.

Ask how each element is held to the wall or floor, and record the answer rather than leaving it as something that was decided on site.

Knowing how a piece is fixed is what allows anyone to alter or remove it later without damage.

The choice of fixing depends on the construction and is a matter for the installer or a qualified professional to determine.

Ask what holds tall units against the wall, and whether any restraint is expected by the maker of a supplied unit.

Supplied units often come with instructions about restraint that are easy to overlook during a busy installation.

Any restraint expected by a manufacturer must be provided as their instructions describe, and confirmed with the installer.

Tell the installer what you actually intend to store, particularly anything heavy, so the fixing choice is made with that in mind.

Installers assume ordinary contents unless told otherwise, and books, records and tools are not ordinary contents.

What the finished storage will carry is for the maker and installer to confirm, and it should not be assumed from appearance.

Ask what happens where a fixing lands on a lintel, a beam, a duct or a boxed pipe, and who decides an alternative position.

Obstructions are found during work, and it helps to know in advance who makes the call when one appears.

Ask what the wall and floor would look like if the storage were removed, so the level of disturbance is a decision rather than a discovery.

This matters at a sale, at a change of use and to anyone redecorating later.

Ask for photographs of the fixings and any services found before the storage is closed up, and keep them with the house records.

Images taken during installation are the only record that will exist once the panels are on.

Ask what dust is expected and what protection is provided to the rest of the house, including the route the installer walks.

Cutting is often done outside or in another room, and the route through the house takes the wear.

Note which rooms will be unusable while work happens, and decide where the contents of the room go in the meantime.

The displaced contents have to live somewhere, and that somewhere is usually another room you need.

Ask what power, water and outdoor space the installer needs, and whether anything in the house has to be turned off at any point.

Being asked at short notice is what turns a small requirement into a disruption.

Agree how the installer gets in and out, who is present, and what happens if nobody is at home, settled before work starts.

Access arrangements made informally are the ones that go wrong.

Note whether children or pets are in the house, and agree what areas are kept separate while tools and materials are about.

This is simpler to arrange in advance than to manage while someone is working.

Agree how questions are raised during the work and by whom, so decisions are not made in passing conversations at the door.

Most disagreements about installed work trace back to a decision made verbally and never written down.

Walk through the finished storage with the installer while they are still present, opening every door and drawer rather than looking at the run.

Fronts and drawers are the parts that need adjustment, and that is easiest while the installer is there.

Ask to be shown how hinges and runners are adjusted, and write down which way each adjustment goes.

Doors settle after installation, and a small adjustment avoids living with a run that no longer lines up.

Keep a written list of anything you want to raise, with dates noted, and share it rather than mentioning items one at a time.

A single list is easier for both sides than a series of remarks, and it records what was agreed.

Ask for the care and cleaning information for every material used, and decide where that paperwork will be kept before it is handed over.

Care information is handed over at the busiest moment and is the first thing to be lost.

Ask what spares, offcuts and product details you should keep, and record what would be needed to order a matching part later.

Matching anything later depends on details that are only available at completion.

Agree in writing what happens if something is found later, including who you contact and how, rather than relying on a verbal assurance.

Written arrangements are what make a later conversation straightforward for everyone involved.
