Rising Damp & Damp Proofing

Rising damp occurs in the walls of buildings when moisture from the ground rises up through the walls of a building. The purpose of a damp proof membrane is to repair the damage done by damp walls and prevent the issue of damp walls from reappearing. The solution involves establishing a horizontal barrier. Such a barrier is created through either Chemical Injection or Electro Osmosis.

Condensation, Mould & Ventilation Systems

Condensation is a growing issue in both dwellings and commercial premises. It is a direct result of improved draught proofing and insulation. We combat the issue by installing a Positive Ventilation System. It regulates humidity levels which prevents the formation of condensation.

Façade/Masonry Cleaning & Restoration

The façade, or the 'face of a building', plays an integral role in the overall appearance and visual impact of the structure. During restoration, extreme care is taken in order to match the appearance of the treated area to that of the original façade.

Tanking & Waterproofing

Tanking involves applying a totally waterproof membrane over a surface, thereby preventing the entry of water. It is a particularly suitable method for water-proofing balconies and basements, along with damp proofing floor screed. The waterproofing of a basement also requires the installation of a Sump Pump system.

Damp Floor Treatment & Concrete Repair

Solid floors are often found to be damp because no effective damp proof membrane is present underneath. To rectify this problem, we apply a Resin Floor Coating which acts as a Damp Proof Membrane, creating a vapour proof epoxy barrier. Meanwhile, our innovative repair solutions allow us to repair all brick and concrete cracks.

What Our Clients Say

We love to hear feedback from all clients; it helps us to continuously improve the quality of our service offerings:

“The need for a major refurbishment of our basement led us to contacting McGuinness Building. Wet walls and dripping ceilings combined had caused significant damage. In addition, the ceilings irregular and vaulted shape made them difficult to access. We knew we needed experts to treat our problem.

From the outset, the team were hands on and provided valuable advice. When the project was ready for commencement, Harry and his team came on-site and worked diligently for three weeks. They applied over 8,000 fixings and the odd ceiling shape proved no obstacle to them.

Following plastering and painting work, our basement is now fantastic- there are zero leaks and the damp smell has been totally eliminated.”

The first viewer of the premises took a five year lease.

“We are extremely happy with McGuinness Building Preservation Ltd as specialist contractors, and would highly recommend them – especially for challenging projects and locations.”
