All work comes with a long-term guarantee.

How do I know if I have rising damp in my home?

Common signs of rising damp include tide marks or staining on lower sections of walls (typically up to 1 metre high), peeling paint or wallpaper, a musty smell, salt deposits (efflorescence) on the wall surface, and crumbling plaster at skirting board level. If you notice any of these signs, contact us on 07515 105926 for a free inspection.

Do you offer a free damp survey or quote?

Yes. SA Damp Solutions LTD provides free, no-obligation surveys and quotes for all damp proofing, timber treatment, and plastering work. We physically inspect your property before quoting — we never price from photographs alone. Call 07515 105926 or email info@sadamp.co.uk to arrange your free survey.

How long does damp proofing treatment last?
Professional damp proofing is designed to be a long-term, permanent solution. Damp proof courses and chemical injections typically last 20–30 years. All treatments we carry out are backed by a long-term written guarantee, giving you full peace of mind.
What is a damp proof course (DPC) and do I need one?
A damp proof course (DPC) is a horizontal barrier built into walls near ground level to prevent moisture rising from the ground into the structure. Most homes built after 1875 should have one. If your DPC has failed, been bridged, or is absent, rising damp can occur. We can inspect your existing DPC and install a new chemical injection DPC where required.
What is the difference between rising damp and condensation?

Rising damp travels upward through walls from the ground, typically affecting the lower metre of internal walls — often leaving tide marks and salt staining. Condensation is caused by moisture in the air settling on cold surfaces, usually appearing on windows, external walls, and in poorly ventilated spaces as black mould. We accurately diagnose which problem you have before recommending treatment, as the solutions are completely different.

Can you treat black mould caused by condensation?

Yes. We provide condensation control solutions including ventilation improvements and specialist treatments that tackle the root cause of black mould. Treating the mould surface alone without addressing ventilation and moisture levels will not provide a lasting fix. We assess your property’s ventilation and humidity and recommend the most effective long-term solution.

What is dry rot and how is it treated?

Dry rot (Serpula lacrymans) is a wood-destroying fungus that thrives in damp, poorly ventilated conditions. It can spread rapidly through timber and even through masonry. Treatment involves removing and replacing affected timber, applying specialist fungicidal treatments to surrounding areas, and addressing the underlying damp source. We offer comprehensive dry rot surveys and treatments across Merseyside.

What is the difference between dry rot and wet rot?

Dry rot is caused by a specific fungus that can spread beyond the damp area into dry timber and masonry, making it far more destructive. Wet rot is caused by several different fungi and stays confined to the area of dampness — it doesn’t spread as aggressively. Both require professional treatment, and we can correctly identify which type you have and carry out the appropriate remediation.

Do you treat woodworm?

Yes. We offer professional woodworm treatment for roof timbers, floor joists, furniture, and other structural timber. Active woodworm infestations are identified by fresh exit holes and fine dust (frass). We apply specialist insecticidal treatments that penetrate the timber to eliminate the larvae. A survey is always carried out first to confirm whether the infestation is active.

How long does damp proofing work take to complete?

Timescales vary depending on the scope of work. A straightforward damp proof course injection to a single wall can often be completed in one day. More extensive work involving timber replacement, re-plastering, dry lining, or rendering may take several days. We will give you a clear project timeline before starting any work.

Is the plasterwork included after damp proofing treatment?

Yes. SA Damp Solutions LTD is a damp proofing and plastering specialist, meaning we carry out all associated plastering, skimming, dry lining, and rendering as part of the same job. You don’t need to source a separate plasterer. This makes the process more convenient and ensures the finished result meets our high standards throughout.

How much does damp proofing cost?

The cost depends on the size of the affected area, the type of damp, and the extent of any associated timber or plastering work required. We provide free, detailed, written quotes following a physical inspection. We are competitively priced and customers on Checkatrade consistently highlight our fair and transparent pricing.

Our team is led by Stuart, a highly experienced damp proofing and plastering specialist who has worked on a wide variety of residential and commercial properties across Merseyside and the North West.
Can damp proofing be done in winter?
Yes, most damp proofing treatments can be carried out throughout the year including winter. Chemical damp proof course injections and timber treatments are not significantly affected by cold weather. However, certain plastering and rendering finishes may require minimum temperature conditions. We will advise you if any aspect of your project is weather-dependent.
Will damp proofing treatment cause disruption to my home?
Some disruption is inevitable when carrying out damp proofing, particularly if old plaster needs removing and replacing or if timber work is required. SA Damp Solutions LTD minimises disruption wherever possible, protects your property during works, and leaves the site clean and tidy at the end of each working day. We keep you informed at every stage so there are no surprises.
