While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

Court Judgment Obtained, Still Unpaid
In June 2022, I hired Aannemersbedrijf Koolmeyer BV for renovation works, including the construction of front and rear dakkapels.
The project was contractually agreed to be completed by September 2022. It was not completed on time, and significant defects remained. Despite several formal opportunities to remedy the issues, the work was not properly finished.
As a result, I initiated legal proceedings.
In December 2023, I obtained a final court judgment ordering Koolmeyer BV to pay approximately €42,000 in damages.
To date, this amount has not been paid.
Enforcement attempts through a bailiff have not resulted in recovery. Under Dutch law, enforcement against a BV can be complex when attachable assets are not immediately available, even when a creditor holds a valid court judgment.
Meanwhile, the company continues operating.
Because the works on the dakkapels were subcontracted, and due to the quality issues, I had to replace and repair them at my own expense (approx. €12,000 additional costs).
I encourage anyone considering working with this company to:
Conduct thorough due diligence
Verify financial standing
Carefully assess risk exposure
If you are another creditor or have experienced similar issues and would like to exchange information, you may contact me.
He has no clue what he is doing
Don't hire them. This is a side proyect of the owner, he has no clue on how to manage anything, the sub sub contractors he hires also don't know what they are doing and are basically begging for accident.
He left multiple issues in the construction and 5 months later I still have no answer from them.
KoolMeyer BV – A Disappointing Experience!
KoolMeyer BV – A Disappointing Experience!
I would not recommend KoolMeyer BV to anyone. They left my house unfinished, delivered poor-quality work, and caused significant delays, taking 7 months longer than originally agreed. After going through the trouble of winning a lawsuit against them, I was shocked to find that they have refused to take any responsibility and have not paid me back a single cent. Unfortunately, Dutch corporate laws seem to protect companies like KoolMeyer BV, allowing them to continue making money while leaving customers like me high and dry.
It's incredibly frustrating to feel that the legal system isn't designed to ensure fair compensation for those who have been wronged. I wanted to share my experience so others are aware—beware of KoolMeyer BV! I strongly advise against hiring them for any projects.
Never hired Koolmeyer or associates
NEVER HIRE KOOLMEYER OR ASSOCIATES
The biggest mistake I did was to trust and hire yasser to do a bathroom renovation. Extremely unprofessional service, he is delegating the project to other contractors, they barely communicate with each other, and they are amateurs. At the end I hired a lawyer to solve the problem , they never finished the project nor taken any responsibility. until today no refund has been made.
