Choosing a reliable tradesperson: checking insurance, guarantees, references
Choosing a reliable tradesperson: SIRET, insurance, decennial guarantee, detailed quote and reachable references, the checks to run before entrusting works.
At a distance, choosing a reliable tradesperson is done on paper, not on a handshake. Four checks remove most bad surprises: the company’s legal existence, an up-to-date professional liability insurance certificate, the decennial guarantee where it applies to your works, and reachable references. A detailed quote and a reasonable deposit complete the picture. All of this can be checked from abroad, in writing, before entrusting any works.
How do you check the company’s existence and soundness?
First reflex: the SIRET number. Any serious tradesperson communicates it without hesitation, and it lets you verify the company’s registration in the public online registers, freely searchable. This check tells you the company’s age, its registered office and its declared activity. An untraceable number, an activity unrelated to the proposed works, a company registered the day before: all signals to take seriously, especially when you will not be able to visit the site yourself and judge the team’s organisation.
Age is not a value judgement: many talented tradespeople are starting out. But a site steered from abroad requires a partner whose structure absorbs setbacks, and whose legal existence is beyond dispute should a conflict arise. Prior verification is your only protection before committing.
Complete this first check with a few simple cross-checks: the business address should exist and match a catchment area coherent with your property; the name signing the quote should be that of the registered company; a reachable landline is worth more than a single saturated mobile line. These details look ordinary: that is precisely why their absence, or their inconsistency, is meaningful.
What insurance and guarantees should you require?
Two documents, not one fewer:
- The professional liability insurance certificate, valid, covering the activity being carried out.
- The decennial guarantee certificate where it applies: this compulsory insurance for the relevant works covers, for ten years, damage that compromises the structure of the work or renders it unfit for its purpose.
For each, three control points: the validity date, which must cover the works period; the declared activity, which must match your works; and the name of the insured party, which must be the company signing the quote, not another entity of the group or a subcontractor. A generic certificate with no activity listed is not a check.
Keep these documents in your file: they will be requested, by you or for you, in the event of a claim or a resale of the property. Works carried out by an uninsured tradesperson can put you in difficulty long after the site is finished.
One point deserves particular attention: subcontracting. The company signing your quote is not always the one carrying out the work. There is nothing abnormal about this, provided the quote states it or you are informed, and every intervener is covered by their own insurance. Ask the question in writing before signing: who works on the site, under whose responsibility, with which certificates. A remote site is hard to steer against three unknowns.
How do you read a quote and check references?
A serious quote is broken down item by item: quantities, materials, equipment, phases, and what is excluded. An all-in quote, “full renovation” with no breakdown, prevents any control: neither over what will be done, nor over what will not. Exclusions deserve as much attention as the rest, because that is where disappointments usually hide.
References complete the picture: ask for projects comparable to yours, with contacts you can reach from abroad, by telephone or email. Three questions are enough in a conversation: was the work delivered as quoted? Were unexpected issues dealt with fairly? Did the tradesperson remain reachable after the final payment?
Compare the quotes you receive on the same basis: same scope, same breakdown, same exclusions. A quote that is much leaner than the others on an identical scope usually omits something, and the omission resurfaces later as a variation, or as work left undone.
| Check | How | Red flag |
|---|---|---|
| Registration | Ask for the SIRET, check it in public registers | Untraceable number or unrelated activity |
| Professional liability | Require the up-to-date certificate | Certificate missing or expired |
| Decennial guarantee | Check validity and activities covered | Works outside the guaranteed activities |
| Quote | Require a breakdown by item, quantities and materials | All-in, vague quote, or pressure to sign |
| References | Contact former clients with comparable works | Unreachable or refused references |
| Deposit | Keep the amount reasonable | High upfront payment demanded from the start |
Why a local intermediary makes the difference
From abroad, these checks take time: calls in French during French business hours, follow-ups, reading technical documents. This is precisely the role of a trusted providers search: pre-selecting tradespeople matching the works, checking their documents, taking references by telephone, and presenting you with a documented shortlist to decide on. Your dedicated contact runs this search on quotation, and then remains your point of passage during the works.
The benefit is not only the time saved: it is knowledge of the local fabric. An intermediary established on the ground knows which trades are credible in your area, which are fully booked, which to avoid, and weighs this information at the pre-selection stage.
Are matching platforms enough?
Online directories and platforms open up an abundant supply of tradespeople, with reviews and sometimes indicators of reliability. They make a good starting point, but they do not replace your checks: a flattering profile proves neither the registration, nor the insurance, nor the actual availability in your area. Customer reviews tell you about the relationship, not about the paperwork.
The approach therefore stays the same whatever the channel: require the SIRET, the certificates, a detailed quote, reachable references. The difference between a platform contact and a recommended tradesperson comes down to one point: the latter arrives with a reputation you can query with the person recommending them. That is a valuable shortcut when choosing from abroad, provided you check that the recommendation genuinely covers works comparable to yours, and not an unrelated one-off job.
Organising your evidence for what comes next
Once the tradesperson is chosen, build a single file: signed quote, certificates, correspondence, photos before the works, schedule. This file serves the handover, the guarantees and any claims; it is worth far more than a memory of phone calls. Keep it tidy enough for someone other than you to read it: your representative on site, an adviser, a professional likely to take over the file. A clear file speeds up every decision, and any possible takeover.
Keeping this file up to date costs almost nothing if done as you go: every document filed on receipt, every decision noted with its date. It is a discipline, not a job; it turns into an asset on the day you need it. The complete steering method is detailed in the guide to steering works from abroad, throughout the Works & renovation category of this journal.
Then comes the question that conditions everything else: the budget. It is the subject of the neighbouring article, the renovation budget for an older property.
Choosing a tradesperson at a distance comes down to file discipline. The personal study offered by French Realty helps you put it in place: pre-selection, verification on paper, checked references, with your dedicated contact.
Frequently asked questions
How do you vet a tradesperson from abroad?
On paper, in writing: a SIRET number checked in public registers, up-to-date insurance certificates, a detailed quote and references you call or email. Everything can be done remotely, before any commitment.
What if the tradesperson refuses to provide their certificates?
Do not entrust them with the works. Providing these documents is standard practice, and refusal is in itself a major warning sign, whatever the explanation offered.
Is a detailed quote enough to secure the works?
No, it is necessary but not sufficient. You also need a verified registration, up-to-date insurance and checked references: the whole file protects you, not a single document.
