Rising Damp

Most UK properties have a damp proof course to prevent rising damp from damaging interiors. Problems can arise if the course is poorly installed, damaged, or “bridged” by high external ground levels. Rising damp can affect plaster, timber, and decoration if left untreated.

Our Solution:

We treat rising damp by injecting the affected walls with our advanced silicone-based damp proof course. Damaged plaster is removed and replaced with renovating plaster, or a specialised cavity wall membrane system may be installed for a long-lasting solution.

Penetrating Damp

Signs of penetrating damp include wet or discoloured walls, mould growth, and damage to decorations. It’s usually caused by porous masonry, defective render, poor window pointing, or roof and gutter defects. Untreated, it can lead to rot, internal deterioration, and structural weakening.

Our Solution:

Our surveyor identifies the source of the damp and recommends targeted repairs. Affected materials are removed, and a physical waterproofing membrane is applied to help the walls dry quickly. External defects are repaired, and walls may be treated with a water-repellent coating to prevent further water penetration.

Condensation & Mould

Modern energy-saving measures like insulation, draught proofing, and double glazing can sometimes trap moisture inside your home. When warm, damp air meets cold surfaces, condensation occurs, which can quickly lead to mould growth, damaged walls, and ruined furnishings.

How We Can Help

Our specialist will carry out a thorough assessment of your property to pinpoint the cause of the condensation. We then recommend and implement tailored solutions, such as improved ventilation systems, extractor fans, or correcting cold spots, to prevent moisture build-up and protect your home from further damage.

Basement & Cellar Waterproofing

Basements and cellars are particularly vulnerable to damp from surrounding ground, which can lead to flooding, damaged walls, and ruined belongings. Proper waterproofing not only protects your home but can also enhance the value and usability of your space.

Our Approach:

We use state-of-the-art waterproofing systems that combine floor and wall membranes to prevent water ingress. Any water is safely directed to a drain or a sump and pump system, ensuring your basement remains dry, secure, and ready for conversion or storage.
