For most routine damp proofing work in Laois, planning permission is generally not required, as it falls under maintenance or internal alterations. However, all damp proofing must adhere to Irish Building Regulations, specifically Technical Guidance Document C, which mandates resistance to moisture for floors, walls, and roofs. It ensures proper installation of a damp-proof course (DPC) at least 150mm above external ground level.
Homeowners in Laois may be eligible for financial support. The Vacant Property Refurbishment Grant can cover substructure works, including damp proofing, for eligible properties built before 2008 and vacant for two years, offering up to €50,000, or €70,000 for derelict homes. Laois County Council also administers Housing Adaptation Grants for older people or those with disabilities, which can assist with structural improvements or dry lining that address damp-related issues. While SEAI grants focus on energy upgrades, such as insulation, which can help with condensation, it’s important to note these are typically separate from direct damp proofing grants.
