Renovating a home is an exciting step for many homeowners. Whether it’s a new kitchen, an extension, or a full home renovation, it often seems simpler than it really is. Yet in practice, many things can go wrong. A poor decision early in the process can lead to higher renovation costs, delays, or even legal issues. In this article, we discuss the five most common renovation mistakes and offer advice on how to avoid them. That way, your renovation can run smoothly and successfully.
INSUFFICIENT PREPARATION
One of the biggest pitfalls is starting without a clear plan. Many people begin demolition or construction enthusiastically without thinking things through. This often leads to delays or unnecessary additional costs. It’s important to write down not just your wishes, but also to explore technical feasibility, structural requirements, and logistical details. What exactly do you want to achieve with the renovation? What is your available budget? Are any permits required? Without this preparation, mistakes are likely.
✅ How to solve this?
Create a concrete renovation plan and define clear goals. Involve an architect or contractor early on for technical advice. Use a checklist and schedule all phases in advance, including the order of work. Also consider a structural inspection to identify hidden defects. Starting well-prepared is half the battle.
UNDERESTIMATING THE COSTS
Another common issue when renovating a house is underestimating the total renovation costs. Hidden problems, such as moisture damage or outdated wiring, can cause expenses to spiral. Many homeowners create overly optimistic budgets or forget to account for unexpected expenses. As a result, they end up cutting quality or dropping certain elements during the project.
✅ How to solve this?
Always request multiple quotes from qualified contractors and base your budget on realistic figures. Add an extra 10–15% as a financial buffer. Discuss the biggest cost drivers with your contractor and which materials or solutions offer the best value. Use a spreadsheet or renovation tool to stay on top of everything.
CHOOSING AN UNRELIABLE OR INEXPERIENCED CONTRACTOR
Choosing the right contractor is crucial. Unfortunately, many people base their decision solely on the lowest price without checking references or making proper agreements. This often results in poor communication, sloppy work, or even abandoned projects.

NOT CHECKING WHETHER A PERMIT IS REQUIRED
✅ How to solve this?
Check before starting the renovation whether your plans require a permit through the Dutch “Omgevingsloket” (environmental permit portal). Discuss this with your contractor or architect, who often have experience with permit applications. Also allow time and budget for applying and waiting for approval. No permit sometimes means: start over.
POOR COMMUNICATION DURING THE RENOVATION
Even with a solid plan, things can go wrong without good communication during the execution. Changes in schedule, material delays, or technical issues are common. Without regular check-ins with your contractor, confusion and mistakes can pile up quickly.
✅ How to solve this?
Set fixed times for meetings with the contractor and request weekly updates on progress. Use a central communication channel (e.g., email or a construction app) to document decisions and changes. Keep a simple logbook to track every step. This keeps you involved and in control throughout the process.
