For businesses buying enquiriesDormer extension leads in the Netherlands

For dormer specialists who want enquiries for a new or replacement dormer.

Which enquiries you receive

The applicant wants a new dormer fitted or an existing one replaced. The preferred width, material and timing have been discussed by phone. Preparation often takes longer, so the planning window is wider than for other work.

Enquiries for a new or replacement dormer extension.

What we check by phone

We have spoken to the applicant about the project, timing and agreed criteria. Stated budgets and measurements remain estimates unless specified otherwise.

  • Owner or authorised decision-maker
  • New or replacement dormer
  • Preferred width and material
  • Budget indication or quote need
  • Project planned within 9 months

What the enquirer states

These details are the enquirer's own indications and are marked as such in the brief.

  • New dormer or replacement of an existing one
  • Preferred width in metres
  • Material preference, for example uPVC or timber
  • Position on the roof: front or rear
  • Budget indication, or a note that a quote is needed

What you do not receive

  • Tenants without the owner's permission
  • General questions about permits without a project
  • Minor repairs to an existing dormer
  • Projects outside the agreed service area

Please note: Klantwerf does not assume that a dormer is exempt from a permit or that a permit will be granted. That is for the specialist and the applicant to assess.

Service area

You choose postcodes or municipalities. We confirm per region whether enquiries are feasible; without that confirmation we promise no volume or delivery time.

Exclusive, and what that means

Klantwerf supplies the same enquiry to one buyer. The applicant may independently contact other providers.

No. You receive a qualified enquiry. Your business handles the quotation, sale and delivery of the work.

Something wrong with an enquiry?

Report incorrect details, a duplicate or a mismatch with the agreed criteria within 7 calendar days. Valid claims receive a replacement or credit after review. Terms are agreed before you start.

Valid reasons

  • Incorrect or non-existent contact
  • No genuine enquiry
  • Outside the agreed service area or criteria
  • Duplicate Klantwerf enquiry for the same project and the same buyer within 90 days

Not a valid reason

  • The enquirer later changes their mind
  • No contract or sale results from the enquiry

Is the enquirer unreachable after delivery? Report it with a short description of your attempts; we review each case individually. As a guideline: three reasonable attempts over two working days, and never continuing after an objection.

A valid report leads to a replacement or a credit, as agreed in advance. Not both. Media bookings follow their own cancellation terms.

Frequently asked questions

No. The file states what the applicant knows about it. The assessment remains with you and the applicant.
