Buildings insurance in Castricum

You are searching for buildings insurance in Castricum. The most common mistake with buildings cover: people enter the WOZ value or purchase price as the insured sum. That is almost always wrong. The WOZ value includes land price and market value, but when a home needs to be rebuilt after fire or storm, what matters is only the actual construction cost — the rebuild value. That is calculated separately.

Homeowners in Castricum who want to check whether their buildings insurance has the right rebuild value and cover. · Updated: 2026-06-13 · Verified by Pieter Smit (Certified Insurance Advisor Wft)

What actually changes by municipality?

Your address does matter for insurance, but not the same way for every product. Postcode is a real factor for car insurance: insurers weight theft risk and claim frequency by area. For contents and buildings insurance, you set the insured value yourself — the municipality says little about it. Liability, travel and legal expenses insurance depend almost entirely on your personal situation, not your address.

What does matter: whether you rent or own, whether you live in an apartment or detached house, and whether your car is parked on the street or in a garage. Those are the details that shape the policy — more than the municipal boundary.

When is your policy due for a check?

A good policy is not defined by the lowest monthly premium. Use these signals to see whether a proper review makes sense.

Signal	Why it matters	What to do
The policy is more than two years old	Your situation, values and usage change; the premium does not adjust automatically.	Compare the policy against your current situation and check whether cover and deductible still fit.
You originally chose on lowest price	Cheap can mean a higher deductible, narrower cover or stricter claims assessment.	Ask what you give up for the lower price — before switching.
Your life has changed	Moving, growing family, living together, working from home, new car or renovation almost always affect a policy.	Start from the change and check which policies need re-evaluating.
You cannot explain when the policy pays out	Policies become expensive at claim time, not at sign-up.	Read the exclusions, sub-limits and deductible — or have an adviser walk through them.

Rebuild value: what it is and why the WOZ figure does not work here

The rebuild value is the amount needed to reconstruct your home from scratch after total destruction — from foundation to roof tile. That is different from the WOZ value (which includes land and market premiums) or what you paid when you bought the property.

Using the WOZ value as your starting point? For a modern home, you are likely underinsured. Construction costs per square metre have risen sharply in recent years. For a detached house, the gap can be tens of thousands of euros.

Underinsurance guarantee clause: some policies commit the insurer not to invoke underinsurance if you have used their calculated rebuild value.
Solar panels, dormers, extensions, conservatories and fitted appliances are part of the building and raise the rebuild value.
Listed buildings carry higher construction costs due to craftsmanship restoration requirements.

Apartment: HOA, buildings cover and the gaps between them

Living in an apartment? The homeowners association (VvE) usually arranges buildings insurance for the whole building. But not always, and not always completely. Request the HOA policy and check what is covered — and what is not. Gaps between the HOA policy and your own buildings cover can leave damage uninsured.

Check whether the HOA policy includes your personal improvements to the apartment.
No HOA buildings insurance? Then you as the owner are responsible.
HOA policy and private buildings insurance can overlap — that is double premium for no extra cover.

One firm, no lead resale

A local insurance search too often ends in a form sent to multiple parties. That generates repeated calls, not better advice. A fair comparison needs context: current policy, cover, claim-free years, home type and the risk you are willing to carry yourself.

What a proper check looks like

Situation first, premium second

A lower premium only matters if the cover still works. The check starts with usage, property, home, car, household and recent changes.

Your current policy is part of the comparison

Without the existing terms, a comparison is shallow. The question is not just what is cheaper, but what you lose or gain.

The real trade-offs get named

Higher deductible, narrower cover, mandatory repair networks, waiting periods, exclusions and duplicate modules — those are what matter.

No means no

If you do not want to change anything after the contact, it stops. A damage check is not an obligation to switch.

Frequently asked questions

How do I determine the rebuild value of my home in Castricum?

Through a rebuild value calculator based on floor area, build year, finish level and home type. Many insurers provide this tool, or an adviser can calculate it for you. Never use the WOZ value as your starting point.

My home has been renovated — do I need to notify my insurer?

Yes, always. An extension, new bathroom, kitchen or solar panels increase the rebuild value. If you do not report it, you risk being paid out based on an outdated amount at claim time.

Does PolisMoment resell my request to multiple parties?

No. Your request goes to one independent advice firm. PolisMoment does not give advice itself and does not resell leads.
