# Who Covers What If Something Goes Wrong on Site

Most owners engage a contractor without ever asking what happens if somebody is hurt or if the flat below is flooded. It is an uncomfortable conversation that takes ten minutes, and it is the only time the answer can still be arranged.

AlcorOne Solutions is an execution-first interior contracting firm delivering turnkey residential and commercial fit-outs across South India. It is headquartered in Chennai, with offices in Hyderabad, Visakhapatnam and Rajamahendravaram.

## Three Events, One Question

Interior sites are small, busy, and full of people using sharp tools at height in a space that also contains water and electricity. The incidents that occur are not exotic:

- A worker falls from a ladder or platform, or is injured by a tool.
- A water line is cut, or a waterproofing failure appears during the works, and the flat below is damaged.
- Material delivered and paid for is stolen, or damaged by water before installation.
- Something already in the flat — an existing floor, a door, a window — is damaged during the work.

Each has an owner in principle. The problem is that the owner is usually determined afterwards, by argument, at exactly the moment when both parties are upset and one of them may not be able to pay.

This article is about settling it beforehand. It is not legal advice, and a project of any size deserves a professional to review the contract — but the questions below are ones any owner can ask and any competent contractor can answer.

## Worker Injury

The first question, and the one owners are most reluctant to raise, largely because it feels like an accusation.

The principle in most arrangements is that people working on the site are the contractor's responsibility, and a firm employing site labour is expected to carry appropriate cover for injury to its workers. The practical step for an owner is simply to **ask whether that cover exists and ask to see evidence of it,** with the policy current for the period of your works.

Two complications are worth knowing about. **Subcontracted labour** blurs the picture — where a contractor engages a separate team for a specialty trade, the question is whether those workers are covered too, and by whom. Ask which trades will be done by separate teams, and whose policy covers each of them.

**Informal engagement** is the other. An owner who directly engages a carpenter or a painter for a small job, paid in cash with no written arrangement, has placed themselves much closer to the risk than an owner who contracts with a firm. That is not a reason never to engage a small trade directly; it is a reason to know that the arrangement is different.

Beyond insurance, the more useful indicator is what the site actually looks like. Proper access equipment rather than stacked furniture, eye protection when cutting, a tidy floor, no trailing leads across wet areas, and electrical tools fed from a protected supply. A site that looks safe usually is, and a contractor who invests in that is generally the same one who carries the cover.

## Damage to Somebody Else's Property

The most financially exposed scenario in apartment work, because the damage is to a third party who is not in your contract.

The classic case is water. A cut supply line, a blocked drain during works, or a failed waterproofing layer damages the flat below — its ceiling, its finishes, sometimes its contents. The affected neighbour will approach the owner, because they know the owner. Whether the cost ultimately rests with the contractor depends on the contract and on what cover the contractor holds.

What to establish beforehand: **whether the contractor carries third-party liability cover,** and **what the contract says about damage to neighbouring property.** The second matters even where insurance exists, because it decides who is obliged to sort it out and who is obliged to pay in the meantime.

A related and often overlooked exposure is damage to the building's common property — a lift interior, lobby flooring, a corridor wall. This is usually what the association's [interior work deposit](https://www.alcorone.com/blog/society-rules-noc-interior-work/) exists to cover, which makes it important to establish who pays that deposit and who bears a deduction from it.

## Material on Site

An interior fit-out accumulates a surprising value of material in an empty, often unoccupied flat — boards, hardware, sanitaryware, appliances, stone. Two risks: theft, and damage before installation.

The question that decides both is **when ownership and risk pass from contractor to owner.** Common positions differ meaningfully. Risk may stay with the contractor until the work is completed and handed over, or ownership may pass on payment while risk stays with the contractor until installation — a sensible arrangement — or both may pass on delivery to site, which leaves the owner carrying the risk for material sitting in a flat they do not control.

That last position is worth noticing, because it is the one that follows by default from a large mobilisation advance with no corresponding term. If you have paid for material that is sitting in the flat and the contract says nothing about risk, establish what happens if it disappears — before it does.

Practical measures matter more than the clause. A single lock with a controlled key list, high-value items delivered close to installation rather than all at once, and appliances left boxed and ideally stored off-site until needed.

## Damage to the Existing Flat

In a renovation there is already something there to damage: an existing floor that is staying, window frames, a main door, a balcony railing, a lift lobby entrance.

Two protections. **A written and photographed condition record before work starts** — walk the flat with the contractor, photograph the existing finishes, and agree the record. Without it, every scratch at handover is an argument about whether it was already there, and that argument is unwinnable in both directions. **Protection in the scope** — floor protection, door and frame protection, and covering for anything retained. This should be a line item rather than an assumption, because if it is not priced it will not be done.

Also worth checking: your own home insurance, if the flat is furnished and occupied. Some policies treat a property undergoing significant works differently, and a brief conversation with your insurer before work starts is cheaper than discovering the position during a claim.

## The Ten-Minute Conversation

Five questions, to be asked of any contractor before signing. None is adversarial, and the quality of the answers is informative regardless of the documents produced.

1. **Do you carry cover for injury to your workers, and can I see it?**
2. **Do you carry third-party liability cover for damage to neighbouring property?**
3. **Who carries the risk for material on site before it is installed, and from when?**
4. **What protection of the existing flat is included in your scope?**
5. **Who pays the association's interior work deposit, and who bears any deduction from it?**

A contractor who answers these clearly has thought about them before, which usually means they have run sites where something went wrong and learned from it. A contractor who has never been asked is not necessarily unsafe — but you will be the one finding out.

## The Honest Limits

Two things worth saying plainly.

**Insurance is not a substitute for competence.** Cover pays for consequences; it does not prevent the flood, and it does not compensate for the weeks of disruption and the relationship with a neighbour. The most effective protection against water damage is not a policy — it is pressure-testing lines and [flood-testing wet areas](https://www.alcorone.com/blog/waterproofing-interiors/) before anything covers them.

**Small projects often run without much of this,** and that is a commercial reality rather than a recommendation. A single wardrobe installed by a two-person team is unlikely to involve documented cover. The point is not to refuse such work — it is to know which arrangement you are in, and to scale the questions to the exposure. A full-flat renovation with plumbing changes in an occupied building deserves all five questions. A single wardrobe deserves the photographs and the protection line.

## Frequently asked *questions.*

### Our contractor says they are covered but cannot produce a document. How much should that worry us?

Enough to pause and ask again, in writing, for the insurer's name, the policy number and the validity period. A firm that genuinely holds cover can produce those easily, because they need them for commercial and institutional clients as a matter of routine. An inability or reluctance to produce them usually means the cover does not exist. That is not automatically disqualifying for a small, low-risk job, but it should change the arrangement: a larger retention, material delivered in stages rather than in bulk, and a careful condition record before starting.

### A neighbour is claiming our work damaged their flat. What should we do first?

Document before you negotiate, and do it immediately. Photograph the damage, note the date, and establish what is actually claimed and what it would cost to remedy. Then notify your contractor in writing straight away — most contracts and most policies require prompt notification, and a delayed report can weaken an otherwise valid position. Resist agreeing liability or offering payment before the cause is established; water travels, and damage appearing below your flat does not always originate in it.

### We paid a mobilisation advance and material is stacked in the flat. Whose is it?

The contract decides it, and in the absence of a term the position is often less favourable than owners assume. Settle it now rather than later: confirm in writing what the advance has purchased, ideally itemised, where that material is, and who carries the risk until it is installed. The pragmatic arrangement that protects both sides is ownership passing on payment with risk staying with the contractor until installation. Alongside that, ask for photographs of what is actually on site, which is also the check on whether the advance bought material at all.

### Does our home insurance cover the flat during a renovation?

It varies by policy and it is worth asking rather than assuming, because some policies restrict or exclude cover while a property is undergoing significant works, particularly when it is unoccupied. Call the insurer before the work starts, describe the scope and duration, and get the position in writing. This matters most for an empty flat during a full renovation, which is both the highest-risk situation and the one where standard cover is most likely to be limited.

None of this is a comfortable conversation and all of it takes about ten minutes. The uncomfortable version happens later, with a neighbour's ceiling on the floor and two parties discovering that nothing was ever agreed.

Ask any contractor, including us, which teams will be on your site and whose cover applies to each of them — and make sure the wet-area and services testing that prevents most of these incidents happens before anything is concealed.
