How does Vert.lu work?

A request takes a few minutes to fill in from the page matching your project: type of work, description of the property, geographic area and preferred timing. The more precise the information you provide — surface area involved, current state of the installation, access to the site — the faster companies can respond with a useful estimate. You do not need an account or any prior document to send a first request.

You can describe several needs linked to the same project, for example roof insulation alongside a heating replacement. The request is then routed to the companies matching each of the trades involved.

Your request is passed on to the companies in our directory whose trade and area of activity match the project described. It is the companies themselves that decide whether to contact you, depending on their availability and workload at the time of your request. Vert.lu therefore does not guarantee a minimum number of replies, but does route the request to relevant professionals.

An interested company usually contacts you by phone or email to clarify a few points, before proposing an on-site technical visit if needed. This visit allows for a reliable quote, particularly for work that depends heavily on the layout of the property.

Response time varies depending on the trade, the time of year and the workload of companies in your area. Some requests get a first reply within a few days, others take longer, particularly for trades in high demand or during peak season. If you have not received any reply after a reasonable time, you can resend your request or contact us to check it was properly forwarded.

No response does not necessarily mean no one is interested in your project: it may reflect a temporary lack of availability among companies active in your area. Slightly widening the geographic area or rephrasing the project description sometimes improves results.

Compare quotes with the same scope: exact nature of the work, materials or equipment specified by brand and model, labour, administrative steps included, deadlines, warranties and the VAT rate applied. A lower price that leaves out a service included in another quote is not necessarily better once the scopes are aligned.

Feel free to ask companies to explain their assumptions in writing, especially when estimates for a similar project differ significantly. A serious professional takes the time to detail their quote rather than just quoting a lump sum.

You can ask at any time for the correction or deletion of the personal data submitted through a quote request, by contacting us directly. We handle such requests in accordance with applicable data protection rules. Deleting your data does not affect exchanges already under way with a company you have contacted directly.

Once a request has been forwarded, companies contact homeowners directly, by telephone or email, using the details provided. If you have received no answer after a few days, first check the spam folder of your mailbox and the details you entered, since a single wrong digit in a phone number is enough to interrupt the exchange. You can then send a new request, widen the area you indicated, or contact us so we can check that the request reached companies matching the trade concerned.

When several companies answer, keep the exchanges in the same place: written quotes, technical questions asked and answers received. This makes it far easier to compare offers that look similar at first glance, and it gives you a documented basis if a disagreement arises later about the scope agreed. Nothing obliges you to accept an offer, whatever the number of exchanges already held, and no contract exists until you sign a quote.

If your project changes substantially, for example a larger surface, a different technical solution or a postponed start, it is better to tell the companies already contacted rather than sending an entirely new request. They can adjust their offer, and you keep a single coherent file for the subsidy application that may follow the work.
