Sealant work in Lopik
Lopik is a ribbon village in the Lopikerwaard, built on one of the thickest peat deposits in the country. The ground here subsides measurably and unevenly. That shows in the buildings: connections that open up, joints that crack, window frames that go out of plumb. Here the joint width follows from the movement and not from habit.

What matters in Lopik
A ribbon over deep peat
Ribbon development along the dyke and the roads through the waard, with farmhouses, houses and outbuildings, and compact residential neighbourhoods in the village centre.
Along the ribbon stand farmhouses and houses of varying ages, often with outbuildings on the same farmyard. There, at a single address, you come across brick, timber, concrete and profiled steel cladding side by side, each with its own product and sometimes a different joint width. In the village centre there are more compact residential neighbourhoods of terraced housing where the original facade sealant is well past its service life; anything dating from before 1994 is suspected of containing asbestos until testing shows otherwise. The agricultural buildings in the waard call for the greatest lengths and the most elasticity.
What makes Lopik different from almost every other place in our area is the thickness of the peat beneath it. Subsidence here is not an exception but a constant, and buildings visibly move along with it. For us that means two things: we consistently choose elasticity over hardness, and we measure the movement instead of adopting the existing joint width, which in practice was often chosen too narrow.
The ribbon is long and the roads are narrow, with ditches right beside the carriageway and little room to pull over. Stopping there with a van takes consultation and sometimes a traffic management measure; we arrange that in advance. On the farmyards the access route is the point to watch: a narrow causeway, a low passage or a farmyard that turns soft after rain is difficult with a fully loaded van. We would rather ask about that beforehand than get stuck.
Twenty-five kilometres from our base, about half an hour. Because the ribbon is long, the last stretch within the municipality can still add considerably to that; give us the address when you enquire, and the quote will be right. For a bathroom or a set of window frames it is easily done; agricultural work usually means several days in a row.

The work here
What we do most often in Lopik
Joints on deep peat
Where the ground subsides measurably and unevenly, a building deforms along with it and that shows in the connections. During the site survey we measure how much movement is to be expected and derive the joint width from that. What sealant does not do is hold back a structure; it follows it, and that is why it needs the room to stretch.
More about this serviceBarns and sheds
Agricultural buildings have long facades of profiled steel cladding, concrete or timber, with joints that run on for tens of metres. On coated steel an ordinary facade sealant does not adhere permanently, and large sheets expand considerably in the sun. We choose by material and by elasticity, and work in sections so that the joint keeps the same width over its full length.
More about this serviceHouse and utility room
Besides the ordinary bathroom, many addresses have a utility room or rinsing room that is used intensively and poorly ventilated. It is precisely there that sealant breaks down faster. We replace the joint and tell you honestly if the ventilation cannot cope with the use, because otherwise the same problem will be back in two years.

Which sealant on what, and what it costs
The substrate decides the sealant
On a farmyard in the waard the requirements are far apart. Brick on the house is porous and has suction; on older masonry a primer goes on first, because otherwise the brick draws the binder out of the sealant. Painted timber requires that the paint layer is firmly attached, because the sealant adheres to that and not to the timber underneath. Coated steel and profiled steel cladding are smooth: they call for chemical adhesion and a lot of elasticity, because large metal surfaces expand strongly in the sun. Concrete is alkaline and dusty at the cut face and has to be clean. And over everything here is the ground: on deep peat we consistently choose a product with elasticity, because a stiff product lasts the shortest on this ground.
Costs and lead time
The price follows from the metres, the accessibility and the number of different substrates, because each product needs its own preparation. On a farmyard with several buildings, taking everything in one visit is considerably cheaper than separate appointments: you then pay the fixed part of the price once. For agricultural work we charge per metre, which makes the budget predictable. For buildings dating from before 1994, asbestos testing comes before the quote. A bathroom usually takes half a day. The curing time is separate from the working time and you get it when the work is scheduled.
Two routes
Business or homeowner in Lopik
For agricultural businesses in the waard it is about long runs on steel, concrete and timber, which suit a fixed price per metre, and where the question of whether the farmyard will bear equipment determines how long the job takes. We check that in advance. For buildings with a function that cannot stand still, we fit the schedule around the business operations rather than the other way round. In the village centre it is about regular maintenance to homes, with handover per address kept in view.
For businesses
Contractors, painters, homeowners' associations, property managers and interior fit-out.

Questions from Lopik
What people in Lopik ask most often
The ground here is subsiding, so can sealant work cope with that?
Sealant work does not hold back subsidence; no product does. What a good joint does do is follow the movement without tearing open, and for that it has to be wide enough and of a type that tolerates a lot of stretch. That is why during the site survey we measure how much movement there is and derive the width from that. What we do not do is adopt the existing width; in practice it was often already too narrow here.
Can you do my barn and my house together?
Gladly, and it makes a considerable difference. The call-out, unpacking and clearing up is the fixed part of every job; you pay for that once if we do everything in one visit instead of per building. During the site survey we go through everything, including what you might not see as sealant work yourself: a connection at a corrugated sheet or a concrete plinth counts as well. Also let us know whether the van can get onto the farmyard and how high we need to reach.
Can work be done while the business keeps running?
Usually yes, but then we plan it around the business operations and not the other way round. Sealant work needs a clean, dry substrate and calm around the joint while it is being applied; dust and moisture are the enemy. For a building that stays in use, we agree which facade is done when. We tell you honestly if a part really cannot be done while operations continue, rather than delivering work that will not hold.
Why does the address within the municipality matter?
Because the ribbon here is long. Lopik stretches over a considerable distance along the roads through the waard, and the difference between the village centre and the end of the ribbon can add up quite a bit. That matters for the drive, and so for the quote. Give us the full address when you enquire, then the amount you get is right straight away and we do not have to adjust it afterwards because it turned out to be further than expected.
How do I know whether it is the sealant or something else?
Look at where the water comes from and when. If moisture gets in during driving rain on one specific facade, a joint that has come loose is a strong suspect. If you see moisture that is also there in dry weather, the problem lies elsewhere: rising damp, a leaking gutter or condensation. During the site survey we tell you honestly if sealant is not the solution; putting sealant in then only postpones the problem and costs you money twice.
