Reliable Damp Proofing Services In Trowbridge

If you’re dealing with damp walls, mould growth, or a musty smell in your property, our damp proofers can help. It’s one of the roofing services in Trowbridge we’re most often called out for, alongside rising damp, penetrating moisture, and condensation, all treated using methods proven across years of local experience in Wiltshire.

Whether it’s a small patch of damp or a full waterproofing project, our experienced team delivers lasting solutions that protect your home’s structure and keep it dry, healthy and comfortable.

What our damp proofing services cover

As experienced roofering contractors in Trowbridge, we know damp problems fall into a few distinct categories, each requiring a different fix. Our qualified team uses advanced methods and high-quality materials to identify, treat, and prevent every type.

  • Rising Damp: Rising damp happens when ground moisture travels up through a wall because the damp-proof course has failed or was never fitted. We, as damp-proofing experts, install or repair a damp-proof course to stop moisture from rising further, then re-plaster the affected area once it’s dried out.
  • Penetrating Damp: Penetrating damp occurs when water enters through cracks in the render, damaged brickwork, or faulty pointing, usually after heavy rain. Our experienced damp proofers trace the water’s actual entry point, which is often some distance from where damp appears inside, and seal or repair it at the source.
  • Condensation: Condensation is the most common cause of damp in UK homes, occurring when moisture in the air settles on cold surfaces. Our damp proofing team fit ventilation and, where needed, insulation improvements to reduce humidity and prevent mould from returning.
  • Basement & Cellar Waterproofing: Keep your lower-level spaces dry and usable with our professional waterproofing systems. We apply durable tanking membranes and coatings that create a watertight barrier against ground moisture.

With our trusted damp proofing services, you can count on us to deliver lasting protection, honest advice, and professional results every time.

How We Handle A Damp Proofing Job

  • Free survey: We inspect the property, use moisture-detection equipment to confirm the type of damp, and identify the actual cause rather than just the visible symptoms.
  • Written report and quote: You get a clear explanation of what’s causing the damp, our recommendations, and a fixed price before any work starts.
  • Treatment: Depending on the diagnosis, this might mean a new damp-proof course, penetrating damp repairs, tanking membranes for a basement, or ventilation upgrades for condensation.
  • Re-plastering and finishing: Where walls need re-plastering after treatment, we use breathable materials suited to the property type, which is particularly important for older properties in Trowbridge.
  • Aftercare guidance: We explain how to keep the property dry going forward, since damp treatment works best alongside sensible ventilation habits.

Everything You Need to Know!

Signs you need damp proofing include a musty smell, mould growth, peeling wallpaper or paint, and dark or damp patches on internal walls, particularly near ground level or around windows.

A single-wall rising damp treatment typically costs between £400 and £1,200, depending on wall length and whether re-plastering is included. Larger jobs like basement waterproofing are priced after a free survey.

A correctly installed damp-proof course or waterproofing system typically lasts 20 to 30 years or longer, provided it’s maintained and any surrounding building work doesn’t bridge it.

Yes. Treatment addresses the root cause, so existing damp dries out and doesn’t return, though visibly damaged plaster usually needs replacing once the wall has dried.

Often, yes. Condensation is usually solved with better ventilation, such as extractor fans or trickle vents, rather than a damp-proof course, which is only relevant to rising damp.

Yes, every damp survey is free and comes with a written report explaining the cause and recommended treatment, with no obligation to proceed.
