“We are demolishing and then we will renovate a larger house. When I saw how many beams and floorboards there are over 50 years old and that they are not rotten even from worms, I offered to the investor that I would keep them, store them and save 20 percent from the original calculation of interior demolition, “confirmed Práva, the head of a construction company. in the Karlovy Vary region.

Demolition costs about 1.5 million, so a 20 percent discount on old wood would be 300,000 in this case. Needless to say, the price of wood is clearly significantly higher.
–
Old wood has always been preserved, but time is the main commodity on construction sites. The interior would have been demolished a long time ago if everything had been thrown together. But the current situation is changing order. Due to the bark beetle, there is a surplus of wood, but it remains small on the domestic market and becomes more expensive by tens of percent.
–
Therefore, in a brick house from the 1930s, workers are now carefully removing the old cladding from the beams that formed the partitions and setting the trampled planks aside. No wonder. Similar new boards would cost 300, 500 crowns per piece.
–
“In addition, what is on the saws is completely fresh wood from the bark beetle calamity. It is full of water, not dry for a moment. It is not good for a pergola or a garden house. The beams are heavy during construction and will twist in a year or two. It wants to let it dry for at least a year, “warned Právo one sales specialist.
–
It is no wonder, then, that some companies have focused on the demolition of barns and other wooden buildings. They will carry out the demolition free of charge and will pay extra if beams and planks can be obtained from the building.
–
“From old granaries, barns, houses offer old beams, roof boards, floor, flap, building cladding. We extract the material ourselves. Payment immediately. The possibility of demolition of the entire building, “offers an entrepreneur from Pardubice on the Internet. He has several ads here and is not alone.
–
“In order to demolish the buildings, I will demolish your buildings free of charge, and I will pay for the excavated beams, rafters and planks. We also carry out the demolition of family houses, farm buildings, waste disposal and the equipment of all relevant permits, “says another interested party from Šumperk.

It is relatively difficult to table the price interfaces for dried or old wood, similarly to new wood. It depends not only on what the wood is, but also on how dry it is, where it was located, whether it did not flow into the original building for a long time, for example, or under what conditions it was stored. It also plays a role whether the beams are carved, which is valued more, or cut on a saw.
–
For example, Mr. Rostislav from Nový Jičín offers elm boards and boards 12 years old, dried to eight percent, stored warm, without worms. Length 2.5 to 3.7 m, thickness 6 cm, cut in the middle. Price 15 to 25 thousand CZK per cubic meter. It has a total of 1.2 m3 available.
–
In Beroun, another six old ceiling beams are offered for 23 thousand, and the offer also briefly warmed up the “barn full of old planks and beams” for 40 thousand.
–
At the same time, frames started by worms are also protected. Near Radotín, a barn about 300 years old was recently demolished near one of the historic buildings. The mayor personally marked the beams, which are “untouchable”. Even the head of a large demolition company came to pick massive beams in person.
–
And that wood dust was pouring out of them? Does not matter. The beams are treated, for example with microwaves. These cause a relatively high heat in the wood and kill the woods. The locals had only a few remnants left to dismantle the stove.
