You expected protection from a building guarantee, but defects or bankruptcy now bring a coverage dispute. Start with your own certificate and conditions. A contractor’s promise, product guarantee and guarantee/security scheme are different commitments. This page helps private clients under Dutch law organise documents and the next question. A rejection, approaching notification deadline or completion decision may warrant a construction lawyer to assess contract rights and guarantee rights together. Provider examples below do not mean your project automatically falls under their schemes.

1. Establish what protection you actually have
Find the document specific to your home or renovation. Check address, parties, certificate number and applicable scheme. Keep the conditions version supplied with the agreement. A general brochure may contain different information from proof that your particular project was brought under a scheme.
Separately list other guarantees. Which part has manufacturer cover and what did the contractor promise? Record whom each document says to contact. Separating categories beforehand prevents notification going only to a party that does not handle the intended risk.
2. Distinguish defect repair and completion protection
Woningborg explains for its post-bankruptcy repair guarantee that a valid certificate is required, the business must actually have been declared bankrupt and the agreement must remain incompletely performed. The scheme may then concern completion or outstanding defects. This differs from assuming every complaint on every job is automatically insured.
Describe the problem: unfinished work, a completed but defective part or a contractor denying liability. State whether bankruptcy is established too. Your question determines which conditions need examination. If uncertain, let an adviser choose the route rather than treating different schemes as interchangeable.
3. Notify under the scheme and record receipt
Read who receives notification and what information is requested. For the relevant bankruptcy route, Woningborg asks for certificate, correspondence and photographs among other things. BouwGarant gives thirty days for bankruptcy notification under its own guarantees. That figure belongs to BouwGarant’s explanation, not every building guarantee. Check your own scheme immediately.
Keep notification, attachments and acknowledgment together. Record unanswered questions. An initial receipt is not automatically substantive coverage confirmation. If a document is missing or more information requested, note what and when to supply it. Seek immediate advice over deadlines; do not wait for a full technical report if timely notice may come first.
4. Assess consequences before your own repair or completion
BouwGarant warns that independently engaging a new contractor after bankruptcy may affect scheme rights. Take that seriously for the applicable route. Ask in writing how necessary intervention, investigation and completion must be coordinated. Where needed, assess urgent damage measures against preserving your claim.
Document existing condition with dates, photographs and a brief description. Note items that may disappear or become hidden by new work. Discuss which facts must first be preserved. Explain why immediate action was necessary and who was consulted. Major renovation and temporary safety protection are different decisions.
5. Examine each reason for rejection
Ask which provision and facts support refusal. Separate reasons: missing certificate, excluded item, cause or procedure followed. Compare each with the relevant document. A general “not covered” message does not yet reveal which question you must answer.
Give the lawyer earlier notification and responses too. Add permission for investigation or repair and state work done since. Request focused assessment of disputed ground, response route and remaining contractual rights. Not every refusal needs the same letter or opponent.
6. Keep guarantee and original agreement together
The scheme is not your only document. Keep contractor agreement, specification, changes and earlier complaints. Who had to provide performance can be distinct from whether a particular guarantee takes it over. The adviser needs both tracks, including existing arrangements with parties.
List desired outcome and estimated practical consequences. Do you mainly need safe habitation, repair or clarity on completion costs? State outstanding payments. These facts help choose useful initial assessment. For overlapping claims, examine how to avoid contradictory promises or duplicate assignments to different contractors.
7. Fictional example: a logo without a clear certificate
Suppose a consumer hires a contractor displaying a guarantee logo on the quotation. Bankruptcy leaves the job half-finished. The consumer cannot find a project certificate and wants another contractor immediately. This fictional example gives no liability or compensation judgment.
A useful first step is sending the logo quotation, full assignment and received guarantee information to the provider, while recording progress. Then assess whether protection exists and what completion route is available. The logo alone is insufficient, but a document missing from your folder does not prove what was applied for without investigation either.
8. Checklist for guarantee advice
Bring certificate and handler’s latest decision on first contact. Flag approaching deadlines or intended completion immediately. Request initial assessment of scheme, notification, rejection and any additional contract route. Agree whether technical investigation or a quick legal response is needed first.
- Certificate, project details and applicable conditions version.
- Construction agreement, specification and additional/omitted work arrangements.
- Notifications, receipts, requests for information and full rejection.
- Photographs, available technical reports and current work condition.
- Bankruptcy details if applicable and planned repair/completion messages.
Frequently asked questions
Does the contractor’s logo automatically give me cover?
Check project-specific protection and conditions with that provider. A logo alone does not establish the scheme applying to your assignment.
Can I hire another contractor immediately on bankruptcy?
First examine arrangements and guarantee rules. Independent completion may affect claims; urgent necessary measures need separate coordination.
Is every building guarantee notification deadline identical?
No. Use your own scheme, not another provider’s deadline as a general rule. Seek advice immediately if uncertain.
Does rejection mean I have no rights left?
Assess both rejection basis and original contract position. Particular coverage and other possible rights are different questions.
