Expert damp proofing

Expert damp proofing

Rising damp and penetrating damp can cause untold damage to any building. Whatever the extent of the problem, we offer a full complement of expert services to suit all needs and all property types. Therefore, you’ll be in safe hands with our damp proofing Yorkshire specialists.

Dry rot

Dry rot

Dry rot poses a serious risk to your home and your safety. It inevitably leads to the weakening of any timber which it affects, causing eventual collapse.  If you’ve discovered dry rot, you should have our experts take care of it quickly.

Wet rot

Wet rot

Where wet rot is eating away at the timber in your home, enlist the help of our trained team to cure the problem. Wet rot is a degenerative problem, meaning that it will likely worsen as time passes; if you spot it, contact us quickly.



Where your home is affected by woodworm, rely on our team of qualified technicians to cure the problem. Tackling a woodworm infestation quickly prevents expansion of the infestation and prevents further damage being caused.

Customer feedback

  • "Fast, effective and great price! Had Allerton Damp in to repair my damp course and replace some damp plaster in my living room. Quality service- the surveyor was friendly and explained everything clearly, then the rest of the staff were polite and friendly. Fantastic and clean result, I'd highly recommend them."

    Alex SWakefield
  • "Allerton tradesmen were very helpful and spent time inspecting the problem we had with damp and mould in a few places within one of our rental properties. There was no hard selling of any products and services, and advice was freely given. The work was completed to a very high standard and I am confident to recommend this company and will definitely use them again."

    Russel BBradford
  • "Very professional company, the job was very well executed and done thoroughly with great customer service. Would recommend to anyone!"

    Tony SLeeds
  • "Would thoroughly recommend Allerton Damp Proofing. Our surveyor was incredibly helpful and was able to clearly explain what was causing our kitchen dampness. Their quote was actually the cheapest and the resulting work was fantastic- 6 months on and still no return of the dampness!"

Who we are

Established in 1983, Allerton Damp Proofing was founded as a small family company, but today we have grown to be Yorkshire’s premier provider of property maintenance services.  We’re regarded as industry leaders in the fields of damp proofing Yorkshire and timber preservation, though we have many other fields of expertise. Our work necessarily involves the laying of new timber flooring, other decorative timber goods such as skirting boards and architraves, specialist plastering, skimming, the adding of specialist insulation to walls, floors and ceilings in addition to pre-purchase damp proofing and timber condition surveys.

The customer satisfaction ratings which we achieve are second to none and this is attributed to the quality of our workmanship and the care that we take with our customer’s properties.  With Allerton Damp Proofing, you can rest assured that you will achieve a lasting solution to your problem; our free 20 year insurance-backed guarantees offer peace of mind for all.

The Property Care Association and damp proofing Yorkshire

 The Property Care Association (PCA) is the trade body with responsibility for the damp proofing Yorkshire and timber preservation industry. Only reputable providers are registered members of the PCA; we have been full members of the PCA since it was founded in 2003. Our affiliation with the PCA is our most important accreditation, worthy of a special mention here.

The PCA provides training and qualifications to members and tradesmen in the damp proofing and timber preservation industry. Our surveyors all have the Certified Surveyor in Remedial Treatments (CSRT) qualification, the most recognised qualification in our industry for remedial surveying. With this, they can carry out specialist surveys, including pre-purchase surveys for home purchase and mortgage purposes. Our Damp Proofing Technicians (DPTs) hold the PCA’s Qualified Technician certificate, which is issued following a rigorous course of study at the PCA’s headquarters in Cambridgeshire.
