Updated on 30 October 2026Our work in Grou: a detached house
We know Grou from more than the map. Here we carried out the maintenance of a detached house with white frames and parapet panels, together with BW Coatings. The work covered the frames and doors, treating the Trespa and the finish in Herfst & Helder.
You can see the photos and the approach in the major maintenance project in Grou. A job like that shows well how we work: first masking and preparation, only then the top coat.
Painting Trespa: can it really be done?
Many houses from recent decades have parapets and panels made of Trespa. When they have gone dull or aged, they don't necessarily have to be replaced. Trespa can be painted, provided the pre-treatment is right. The material is smooth and hard, so without proper preparation the paint won't bond.
In Grou we did that, together with BW Coatings. On painting Trespa we explain the steps. You can also ask whether it is feasible for your panels, and we will look at that during the site visit.

Water village on the Pikmeer
Grou lies on the Pikmeer, on the route of the Prinses Margrietkanaal, and since 2014 has been part of the municipality of Leeuwarden. It is one of the best-known watersports villages in Friesland, and every February it has its own festival, Sint Piter. In and around the village many houses stand close to the water.
You notice that on the facades. Damp and wind do their work, especially on the south and west sides and on the waterside. How we deal with that you can read under painting by the water.
If you have your own mooring, you would rather not have scaffolding at your door in the boating season. So it is wise to call in good time, so we can choose a period together that fits how you use the house.
Major maintenance is more than a new coat
With major maintenance we assess the whole house. Where is the paint coming off, where are the joints open, and where is the wood soft? Rotten parts come out back to sound wood. Then the fixed steps follow: degreasing, sanding, priming, filling, sealing and two top coats.
If you want to keep it in good order afterwards, you can do that with a long-term maintenance plan for 5 or 10 years. With it, a 10-year guarantee applies. A plan is not an obligation, but it prevents you from having to take such a big step again in a few years.
What we would like to see from you
Send photos of all the facades, of the frames that worry you and of any panels or Trespa. Add when the home was built and when it was last painted. If your house is on the water, show the water side too.
During the site visit we look at the surface, discuss the colours and agree the work. After that you receive a quote that states exactly what will happen.
If you want Trespa or panels treated, also take a photo of the edges and the fixings. That often tells us more than a photo of the whole surface.

What a big job in Grou can cost
Major maintenance is tailor-made. The surface area, the condition of the wood, Trespa and the scaffolding make the difference. A national market indication is exterior painting from €35 per m2, an exterior frame from €50 each and wood rot from €50 per spot. These are not MJA prices.
With us you get a fixed price after the site visit, and our own scaffolding has a fixed price for putting it up and taking it down. Painting work on a home that is two years old or older carries 9 percent Dutch VAT.
With a large home, the split matters too. You can have everything done at once, or divide it into stages. Then you see in the quote what happens now and what later. We discuss the order at the site visit.

"Clear information about the work on our dormer. Good communication. A partly less successful result was still repaired perfectly."
"Arrived at roughly the agreed time. Friendly introduction. Delivered good work."
"After a small miscommunication at the start, MJA Allround did a fantastic job. The garage was painted. They neatly masked and lightly sanded everything first and used a lovely deep matt black paint."
"Incredibly professional company, helped us out of a tight spot when another contractor had let us down. Arrived within a day and finished the house in 3!"
"Fine company. Skilled and friendly staff. They also give extra tips."
"Clear agreements and easy communication."
"Delivered a beautiful result and very pleasant communication."
"These really are craftsmen who know their trade. Our house badly needed work, it had not been maintained for 10 years. They explained everything well. Once they started they found a lot of wood rot, it was shocking, but thanks to MJA Allround Bouw our house looks sharp and beautiful again."
"This craftsman delivers quality work. Very happy with the job. Agreements are kept and it was finished within the agreed time."
"I recently got the keys to my new-build flat and three craftsmen applied glass fibre wallpaper and painted everything expertly (about 150 m2)."
"The fascia boards had to be replaced at short notice. MJA Allround Bouw responded very quickly and delivered excellent work. Their advice and communication were also very good."

Frequently asked questions
The questions we get most often, with an honest answer.
Have you worked in Grou before?
Yes, in Grou we carried out the maintenance of a detached house, together with BW Coatings. Trespa was also treated and finished in Herfst & Helder. The photos are with the project.
Can Trespa be painted instead of replaced?
Often, yes, if the pre-treatment is right and the panels are still firmly fixed. At the site visit we look at the condition of your panels. That way you know whether it is the right choice for your home.
How long does major maintenance take?
That depends on the size of your house, the preparation and the weather. The quote states what will happen, and we agree a period with you. We only paint on dry wood.
What guarantee do I get on major maintenance?
The guarantee period is always stated in the quote and the terms. With a long-term maintenance plan for your home, a 10-year guarantee applies.
