Damp Proofing That Stops Problems for Good
Damp can ruin walls, damage timber and create unhealthy living conditions. At Hallmoore Developments we do not just cover up the signs, we fix the cause with proven, long lasting solutions.
Our damp proofing systems include damp injection cream which creates a powerful chemical barrier against rising damp, stopping moisture from travelling up your walls. We use DryRod damp proofing rods which provide high performance treatment for targeted areas and are ideal for severe or stubborn damp patches.
We install full tanking systems using waterproof membranes or slurry coatings for basements, cellars and ground-level walls to keep them completely dry. We also offer cavity drainage membranes that redirect water away from internal walls, allowing rooms to stay dry and breathable, and external weatherproof coatings that stop penetrating damp caused by driving rain or porous brickwork.
Homeowners choose us because we combine expert diagnosis with the right system for each property. There are no one size fits all fixes. Every job comes with a clear written guarantee and we work cleanly to protect your home while we install your damp proofing.
Whether it is rising damp, penetrating damp or condensation, our treatments are designed to stop the issue permanently, protect your property value and give you a healthier, warmer home.

"Hallmoore carried out a full damp injection treatment in our dining room. The survey was clear, the work was completed on time, and the results are amazing. No more musty smell or bubbling paint, and the walls are completely dry."

⭐⭐⭐⭐⭐
"We had persistent damp patches in our hallway for years. Hallmoore used DryRod damp proofing rods and explained every step. Six months later the walls are still bone dry and the finish looks great. Professional and very tidy team."

"Our basement had constant moisture problems. Hallmoore installed a full tanking system and cavity drainage membrane. It is now completely dry and we can actually use the space for storage. I would recommend them without hesitation."
Frequently asked questions
Q: Do you cover my area?
Yes — Hampshire & Dorset including Christchurch, Bournemouth, Poole, New Forest, and surrounding towns.
Q: What are the signs I need damp proofing?
Peeling paint, salt marks, musty odours, black mould, crumbling skirtings, or a high moisture reading on lower walls.
Q: How do you diagnose the cause of damp?
We survey the property, take moisture readings, check ventilation, gutters/pointing, and identify whether it’s rising, penetrating, or condensation-related.
Q: What treatments do you use?
We use the right method for the cause: DPC cream/rods (e.g., DryRod) for rising damp, tanking/slurry or cavity drain membranes for below grade walls, plus fixing external defects.
Q: How long does damp proofing take?
Small areas: 1–2 days. Whole ground floors or basements: typically 3–5+ days depending on drying/finishes.
Q: Is the work guaranteed?
Yes — our damp proofing comes with a workmanship guarantee, and manufacturer warranties apply to products used.
Will you replaster after treatment?

Q: How much does it cost?
Costs depend on the cause, area, and finish. We provide a free survey and written quote before any work.
