Fortunately, rotting mudsill can often be easily replaced. Due to individual factors affecting each case, it’s important to work with a professional contractor so that the structural stability of your home is not compromised.
The basic steps in mudsill replacement include removing the weight from the mudsill, removing the mudsill and any surrounding damage, creating a new mudsill to fit the space and adhere to the current building codes, installing the new
mudsill, inspecting the new mudsill, and insulating the area. To keep the house level, rotting mudsills need to be professionally replaced.
To do so, the structure will need to be lifted so that the damaged sill plate can be removed. The damaged sill is then replaced with pressure-treated lumber and anchored to the foundation wall in full accordance with the current building code. Insulation in the form of foam padding is added between the sill and foundation wall, and a support beam is fastened.
To complete the process, the structure is carefully raised back into place through hydraulic jack lifting. This process is performed gradually to avoid structural or internal damage.
