We’re trusted damp proofing specialists in Sheffield with decades of experience. Our team is fully trained and ready to assess, treat and repair all types of damp problems.

What Is Damp Proofing?

Damp proofing is a way to stop moisture from damaging your walls, floors or ceilings. When moisture builds up in a home, it can lead to black mould, flaky paint, warped floors and bad smells. Left alone, damp can also affect your health and damage the structure of your home.

There are a few different types of damp, and each needs its own fix. That’s why our work always starts with a proper survey. We’ll identify the cause of the problem and talk you through the best way to put it right.

Basement and Cellar Waterproofing

If you’ve got a basement or cellar, waterproofing it properly is key, especially in Sheffield where older homes often have underground spaces. We offer full basement and cellar waterproofing services, including:

• Tanking Cellars and Cellar Conversions: This involves applying a waterproof barrier to the inside of cellar walls and floors. It stops water from entering, and helps you turn a damp, unused space into a dry room you can actually use.
• Tanking Basements and Basement Conversions: Similar to cellar tanking, we seal the inside walls with a strong, waterproof coating. It’s ideal if you want to convert your basement into a home office, playroom, or extra living space.
• Cavity Drain Membranes: For ongoing protection, we can install a drainage system that manages moisture and channels it away from the building.
• Sump Pumps and Drainage: In high water areas, we’ll fit sump pumps to remove water before it causes problems.

We’ll inspect your space, recommend the best solution and carry out the work to the highest standards. Once tanked and waterproofed, your cellar or basement can become a dry, safe part of the house.

Rising Damp Treatment

Rising damp happens when moisture from the ground moves up through the walls of your home. It’s common in older buildings without proper damp proof courses. Signs of rising damp include:

• Dark patches on the lower parts of the walls
• Peeling paint or wallpaper
• Salt marks on the wall surface
• A damp, earthy smell

We treat rising damp by installing or repairing damp proof courses and injecting damp proof creams into affected walls. These create a barrier that stops water from rising. We’ll also check for damaged plaster or insulation and repair those as part of the job.

Penetrating Damp Treatment

Penetrating damp is caused by water getting through walls, roofs or windows. It often comes from broken gutters, loose tiles, or cracks in the pointing. We fix penetrating damp by:

• Repairing the source of the water (such as guttering, render or roof tiles)
• Sealing external walls
• Replastering damaged areas inside
• Repainting with moisture-resistant paint

Unlike rising damp, penetrating damp can appear anywhere on a wall. It needs proper inspection and fixing at the source.

Condensation and Cold Spots

Condensation is the most common form of damp in homes. It happens when warm air hits a cold surface, like a wall or window. You might see water drops on the inside of windows or mould in corners of the room.

We fix this by improving airflow, insulating cold spots, and advising on heating and ventilation. In some cases, we may install air vents or extraction fans to help reduce moisture in the air.

Cold spots on walls often point to poor insulation. These areas stay cooler than the rest of the room, attracting condensation. We’ll assess where heat is being lost and suggest how to improve it, whether that’s internal insulation, external rendering or another method.

Window Condensation and Wet Walls

Wet walls and steamed-up windows can make a home feel damp and uncomfortable. They can also lead to black mould around the frames or corners of the room. We can help by:

• Installing trickle vents or fans to improve airflow
• Improving insulation around the windows
• Sealing window frames to stop air leaks
• Replacing cracked or damaged glass

Dry Rot and Wet Rot Treatment

Rot is a serious issue that can spread fast if not caught early. It affects timber, floorboards, skirting boards and structural beams. There are two main types:

Wet Rot

Wet rot is caused by long-term damp conditions. It makes timber soft, spongy and weak. We treat wet rot by:

• Removing the affected wood
• Drying out the area
• Treating surrounding timber to stop it spreading
• Repairing or replacing the damaged structure

We also look out for wet rot fruiting bodies. These are mushroom-like growths that show the rot is active. We’ll remove them and treat the area with anti-fungal agents.

Dry Rot

Dry rot is more aggressive and can spread through walls as well as wood. It starts in damp conditions but can travel through dry areas. We deal with dry rot by:

• Finding the full extent of the damage
• Removing all affected material
• Treating walls and timbers with fungicide
• Making sure the area is fully dry and sealed

Both types of rot can affect the strength and safety of your home. If you think you’ve spotted it, contact us straight away.
