A contractor coordinates and carries out construction projects, from minor renovations to complete new construction. As the main contractor, a contractor engages professionals such as masons, carpenters, electricians and plasterers.
During a renovation, the contractor arranges the entire process: from construction drawings and permits to the actual implementation and delivery. This saves you the complexity of managing multiple professionals yourself.
Contractors also specialize in extensions, dormer windows, excavating basements, foundation repairs and complete renovations. An experienced contractor will deliver the project on time and within budget.
For every construction project where multiple disciplines come together, a contractor is the appropriate party. Consider an extension, kitchen renovation, bathroom renovation or installing a dormer window.
You also need a contractor who works with a structural engineer for structural changes, such as removing a load-bearing wall or strengthening a foundation.
For larger projects, it is wise to engage a contractor for the permit application. They know which documents the municipality needs and can speed up the process.
Ask for references and view previous work by the contractor in The Hague. A reliable contractor will be happy to show photos or addresses of previous projects.
Check whether the contractor is registered with the Chamber of Commerce and preferably affiliated with a trade organization such as Bouwend Nederland or NVOB.
A good contractor works with a detailed quotation and construction schedule. Be careful with contractors who do everything "by heart" or do not want to make written agreements.
Compare at least three quotes. When it comes to renovations, price differences of 20-40% are normal, so comparing can save thousands of euros.

A local contractor in The Hague knows the municipal building regulations and has contacts with local suppliers. This means shorter delivery times, lower transport costs and a smoother permit process. Plus, you can easily drive past previous projects to assess the quality of the work.
The costs depend greatly on the project. A minor renovation costs 3,000 to 10,000 euros. An extension or major renovation can cost up to 25,000 to 50,000 euros. Always request multiple quotes.
A bathroom renovation takes on average 2 to 4 weeks. An extension 6 to 10 weeks. The duration depends on the complexity and whether permits are required.
That depends on the work. An internal renovation is usually permit-free. An extension, dormer window at the front or extra floor often requires an environmental permit.
A good contractor communicates proactively about delays. Agree on a delivery date in advance and include an arrangement for extension in the contract.
