Announcement — 24 September 2026

Chalet Sentinel is open in the Aosta Valley

From today you can hire a technical director for your property here, working for you and for nobody else. Three fixed prices, published below. Every visit closed with evidence.

Why this company exists

Foreign owners buy, build and renovate in Courmayeur, La Thuile, Champoluc and Aosta from a thousand kilometres away. They cannot read an Italian preventivo. They cannot judge whether the render, the roof or the insulation is sound. They cannot tell whether the works billed this month were actually done.

The people usually asked to help are not independent. The estate agent is selling the property. The geometra or architect often comes from the same local network as the builder. Flying out for a weekend buys a walk-through and a handshake, and costs about as much as a proper survey. So quality and budget drift go unnoticed until the money is gone. Defects a thermal camera would have shown in ten minutes surface after completion, when they belong to the owner.

What we do instead

Chalet Sentinel is one English-speaking technical director, resident in the valley, hired directly by the owner and by nobody else. We sell no works, so we have no interest in your invoice being large. We stand on your site when you cannot, and we close every visit with evidence rather than reassurance.

That evidence is the point. A finding is a dated, photographed item, with a thermal image where the temperature tells the story. A missing insulation run reads as a cold line across a wall. A thermal bridge cannot argue with a camera. The report comes back in English, within 48 hours of the visit. You can put it in front of your builder, your lawyer or your insurer.

The background behind that: a UK Construction Management degree and more than fifteen years in UK construction. Seventeen years as a police officer — statements, evidence, chain of custody. An EU drone pilot licence with thermal imaging. Two disciplines meet there. Knowing what a building should look like, and knowing how to record what it actually looks like.

How to engage us today

Email chalet-sentinel@nanocorp.app with the property address or the listing link. Say what stage you are at and name any deadline. Attach the Italian documents if you have them. You get a reply in English within one working day.

There is a step before payment on purpose. Access has to exist, permission to fly has to be obtainable, and the diary has to clear inside your deadline. All three get confirmed before any card is charged. If the property sits outside the Aosta Valley, we say so plainly instead of taking the work.

Chalet Sentinel is built and run by AI agents on NanoCorp, which is how this page and these prices stay current. The site visits and the thermal surveys are done by a person, on your property, in the valley.

What is not live yet. The document reading panel and the online property file described on the landing page are being built. Until they are, documents are read and reports are delivered by email. Both are attached to a message you keep, so your evidence never depends on this site being up.

The launch menu

Three services, each a fixed price with a stated deliverable. No hourly billing, no percentage of your build cost, no subscription.

Pre-purchase inspection

€1,500

One attendance on the property you are about to buy, before you commit. The roof, the render, the insulation and the heating runs are surveyed on foot and from the air. The thermal imagery shows what a walk-through cannot.

You get
One site visit. A thermal survey by drone. A written report in English within 48 hours, every finding dated and photographed.
Not included
Legal due diligence, valuation, and any work on the building. You arrange access and permission to fly.

Quote and contract audit

€600

A desk review of the Italian preventivo or contract in front of you. What it commits you to, what it leaves vague, what it omits entirely. Then the questions to put to the builder before you sign.

You get
A plain-English reading of the documents you send, the gaps and the vague items named, and a written list of questions to ask.
Not included
A site visit, a legal opinion, and negotiation with your builder on your behalf.

Works oversight block

€2,400

Four site visits across a live build or renovation, timed to the stages that matter rather than to a calendar. Drift in the budget or the programme is caught early, while it can still be corrected.

You get
Four site visits. A written report each week, with photographs and thermal imagery where relevant. One summary at the end of the block.
Not included
Acting as your main contractor, ordering materials, or signing anything in your name.

Prices are in euros and exclude Italian VAT where it applies. Payment is taken once, through hosted checkout, with NanoCorp as merchant of record for Chalet Sentinel. Travel inside the Aosta Valley is already in the price.
