Replacement of crowns and repair of load-bearing structures in wooden houses.

Wood is an excellent building material in terms of environmental friendliness and physical characteristics. It has low thermal conductivity and, due to its naturalness, creates comfort and coziness inside. But because of its naturalness, it is highly susceptible to the influence of negative factors, including moisture and living organisms. Therefore, when building a house, it is necessary to have not only theoretical knowledge in the field of construction, but also theoretical knowledge in the field of wood science, and practical skills for working with wood. Any of the obvious little things: under-dried wood, an improperly executed foundation, improper house installation, incorrectly performed painting or sealing, improper operation, etc., can lead to irreversible rotting processes beginning in the wood, which at a certain stage can lead to the house eventually becoming unfit for use and living.

In this case, it is necessary to repair the rotting structures as soon as possible and replace them with the same ones made of normal wood. In some cases, they resort to a kind of "freezing" of the rotting wood of a house made of profiled or rounded timber, by carefully treating it against fungus, rot, woodborers, and other causes that caused the deterioration of the house, and sewing the house into a "shell" of profiled timber. This method is called "blockhouse sheathing". The negative side of this method is that it does not completely eliminate the problem.

In a house made of rounded or profiled timber, the bottom crown, which comes into contact with the foundation, most often rots. In this case, the most effective method of eliminating this problem is replacing the bottom crown with a new one. This method is quite laborious, requiring the use of chainsaws to cut out rotten crowns and insert new crowns partially or along the entire length.

In frame houses made of wooden beams, everything looks simple only at first glance, because the user cannot see the power frame, which is sewn up with OSB boards and sheathing, but with the wrong manufacturing technology, non-compliance with technological and building codes, the rotting process can be started in the frame wood. To stop it, it is necessary to replace the rotting elements. To do this, it is necessary to perform a no less laborious process of opening the walls and floor for access to the power frame.
