If you own property in Yorkshire and you’re trying to sort a serious damp problem, the companies worth considering are those with relevant professional credentials, clear guarantee terms, genuine regional coverage and a verifiable customer record. That combination matters more than most people realise.
Damp isn’t a cosmetic nuisance – left untreated, moisture can rot timber, ruin plaster and reduce the value of the older stone and brick housing stock found across the county. Yorkshire’s mix of exposed heritage buildings, a wet climate and variable ground conditions means damp can appear in different ways, and a quick surface treatment may not address the cause.
Our top pick is All Dry Damp Proofing for South and West Yorkshire homeowners, landlords and commercial clients seeking accredited, guarantee-backed work. It combines more than 25 years of Yorkshire experience with PCA approval and CSRT/CSSW-qualified surveyors. Guarantee Protection Insurance is available on completed work, and the company displays more than 120 customer reviews. For buyers across Yorkshire who want a free survey and a 20-year guarantee, thinkDRY is a practical alternative. For Leeds and surrounding areas, Leodis Damp Control is also worth shortlisting for damp treatment and basement work.
Below, you’ll find all seven companies ranked and explained, each judged on the same four criteria: accreditation, guarantee quality, coverage, and independently verified reviews. Every entry names exactly who it suits best, so you can shortlist quickly.

How We Ranked These
We didn’t rank on reputation alone or on who shouts loudest. We used four practical pillars that matter to a property owner who wants the problem solved once. Here’s what each one means and why it earns a company a place among the best damp proofing companies in Yorkshire.
Professional Accreditation
The clearest signal of a competent damp specialist is relevant training and membership of an established trade body such as the Property Care Association (PCA). On top of that, look for surveyors who hold CSRT (Certificated Surveyor in Remedial Treatment) and CSSW (Certificated Surveyor in Structural Waterproofing) qualifications. Those credentials show formal training and assessment rather than an informal inspection. They help reduce the risk of misdiagnosis and unnecessary remedial work.
Guarantee Quality
A standard contractor guarantee depends on the contractor remaining in business. An insurance-backed guarantee is intended to provide cover if the contractor ceases trading, subject to the policy terms. That distinction can matter for landlords and buyers who need transferable evidence of remedial work, so check the insurer, duration, exclusions and transfer conditions.
Geographic Coverage
Yorkshire isn’t a single market. A firm rooted in Sheffield behaves differently to one based in Leeds, and coverage across South, West and North Yorkshire genuinely varies. We favoured companies with real multi-town reach over single-city operators, whilst being honest about where each one is strongest.
Verified Customer Reviews
Independent review platforms such as Checkatrade provide a signal beyond a company’s own marketing, although volume and recency both matter. We used review counts only where they could be confirmed.
The 7 Best Damp Proofing Companies in Yorkshire (2026)
Each company below is compared against those four pillars and matched to the buyer or job it appears best suited to. The list starts with our top overall fit and then moves through more location-specific or service-specific options.
#1. All Dry Damp Proofing – Best for South and West Yorkshire Homeowners, Landlords, and Commercial Clients Needing Fully Credentialled, Guarantee-Backed Work
All Dry Damp Proofing is a Barnsley-based firm with over 25 years of experience treating damp across South and West Yorkshire, covering Sheffield, Barnsley, Rotherham, Doncaster and Huddersfield. It handles damp proofing, damp surveys, condensation control, wet and dry rot treatment and basement conversions, allowing complex jobs to stay with one contractor. If you want damp proofing specialists whose PCA approval and surveyor qualifications are clearly stated, this is where the list starts.
What earns All Dry the top spot is the combination behind the work. The company is PCA approved, and its surveyors hold CSRT and CSSW qualifications – recognised credentials for remedial treatment and structural waterproofing. That matters because damp problems are often misdiagnosed, and a qualified survey helps reduce the risk of paying for the wrong treatment. Guarantee Protection Insurance is available on completed work, providing cover if the company ceases trading, subject to the policy terms. More than 120 customer reviews are also displayed online, giving buyers a substantial record to examine.
Key features:

Who it’s best for: Homeowners, landlords and commercial clients across Sheffield, Barnsley, Rotherham, Doncaster and Huddersfield who want PCA-approved, survey-led work and an insurance-backed guarantee option. It is particularly relevant where transferable protection matters.
#2. Dampcure Ltd – Best for South Yorkshire Properties Needing Damp Treatment or Basement Waterproofing
Dampcure Ltd is based in Chesterfield and serves South Yorkshire, Derbyshire and Nottinghamshire. Its services include damp and timber surveys, rising damp treatment, timber treatment, condensation control and structural waterproofing for basements. For South Yorkshire owners near the Derbyshire border, that cross-regional coverage can be practical.
The company is CHAS approved for structural waterproofing work and states that its surveyors are PCA trained. It is better suited to South Yorkshire than Leeds, so buyers should confirm that their postcode falls within the active service area.
Pros:
- Covers South Yorkshire alongside Derbyshire and Nottinghamshire
- Offers damp and timber surveys before remedial work
- CHAS-approved structural waterproofing and basement conversion services
- Works with both residential and commercial properties
Cons:
- The Chesterfield base is less convenient for West and North Yorkshire
- Coverage is regional rather than Yorkshire-wide
- Confirm the surveyor’s individual qualifications and guarantee terms for the proposed work
Best for: South Yorkshire owners seeking damp treatment, timber work or structural waterproofing from a Chesterfield-based regional contractor.
#3. thinkDRY – Best for Property Owners Wanting Broad Coverage and a Free Survey
thinkDRY offers damp proofing across Yorkshire and beyond, with free surveys and a 20-year guarantee advertised across its service pages. Its small-family-business model and broad coverage suit owners who want a straightforward initial assessment and quote.
The company states that it is fully insured, but its public site gives less detail on named surveyor qualifications than the client section. If specific accreditation is required, confirm the relevant credentials before booking.
Pros:
- Broad service coverage across Yorkshire
- Free damp surveys are advertised across its service pages
- A 20-year guarantee is advertised for damp-proofing work
- Small family-business model with damp, tanking, condensation and timber services
Cons:
- Named surveyor qualifications are not prominent on the main site
- Broad coverage means local availability should be confirmed
- Check the guarantee’s exclusions, transfer terms and applicable treatments before booking
Best for: Yorkshire property owners who want broad coverage, a free survey and clearly advertised guarantee terms.
#4. Leodis Damp Control – Best for Leeds and Wider Yorkshire Damp Treatment and Basement Work
Leodis Damp Control is a family-owned Leeds-based specialist offering rising and penetrating damp treatment, condensation control, timber treatments and basement conversions. It serves Leeds, Harrogate, York, Castleford, Wakefield, Sheffield and Barnsley, giving it broader reach than an exclusively Leeds-focused operator.
Its wide service range suits buyers who want one contractor to assess moisture problems and handle related waterproofing or timber work. Public accreditation details are less prominent, so confirm qualifications and guarantee terms before booking.
Pros:
- Family-owned Leeds base with a broad damp-control service range
- Offers rising and penetrating damp treatment, condensation control and timber treatment
- Also provides basement conversions and related waterproofing work
- Serves Leeds, Harrogate, York, Castleford, Wakefield, Sheffield and Barnsley
Cons:
- Public accreditation details are less prominent than for some specialists
- Guarantee terms are not set out clearly on the main service pages
- Buyers outside the listed areas should confirm travel and availability
Best for: Buyers in Leeds and the listed Yorkshire towns who want damp treatment, timber services or basement work from one regional contractor.
#5. Damp2Dry Building Solutions Ltd – Best for Barnsley, Sheffield and Leeds Projects Needing Damp and Building Work
Damp2Dry Building Solutions Ltd is based in Barnsley, with service points in Sheffield and Leeds, and pairs damp proofing with wider building solutions. That combination is useful when treatment leads to follow-on work such as replastering, basement waterproofing, cellar conversion or associated repairs.
The company advertises free surveys and a company warranty. Confirm the warranty length, exclusions and any insurance-backed option for the proposed job before booking.
Pros:
- Strong fit for Barnsley, Sheffield and Leeds customers
- Combines damp proofing, timber treatment and basement waterproofing
- Can also handle cellar or garage conversions and related building work
- Free surveys are advertised
Cons:
- The core service area is concentrated around Barnsley, Sheffield, Leeds and nearby towns
- The main site refers to a company warranty but does not state one standard duration
- Specific professional accreditations are not clearly listed on the main site
Best for: Barnsley, Sheffield and Leeds owners who want damp treatment plus related building or conversion work.
#6. Home Building & Surveying Company – Best for Damp Treatment Alongside Wall Coatings or Property Preservation
Home Building & Surveying Company is a damp and property-preservation contractor rather than an independent building-survey practice. Its services include damp proofing, wall coatings, basement tanking, mould remediation, woodworm treatment and condensation control. That broader range can suit owners who want diagnosis and remedial work managed by one provider.
The company advertises nationwide coverage, so it is not a Yorkshire specialist. Yorkshire homeowners should confirm local surveyor availability, response times and who will carry out the work before booking.
Pros:
- Wide range covering damp proofing, wall coatings, mould, woodworm and condensation
- Basement tanking and remedial treatments can be handled alongside damp work
- Free damp surveys are advertised
- Nationwide operating model may suit multi-location property owners
Cons:
- It is a treatment provider, not an independent building-survey practice
- It is not Yorkshire-specific, so local availability should be confirmed
- Confirm the attending surveyor’s qualifications and the guarantee terms before booking
Best for: Property owners who want damp treatment combined with wall coatings, mould work or wider property-preservation services.
#7. MP Damp Proofing Services – Best for West Yorkshire Customers Wanting a Review-Backed Independent Specialist
MP Damp Proofing Services is a Southowram-based independent operating across West Yorkshire, including Leeds. Its Checkatrade profile lists more than 20 years of industry experience, PCAQT qualifications, damp assessments, waterproofing, timber treatments, basement conversions and condensation control. It also states that 10-year insurance-backed guarantees can be provided on request.
The operator’s large review volume and broad service list are useful signals, but the sole-trader model may mean availability depends on current workload.
Pros:
- More than 20 years of industry experience stated on its Checkatrade profile
- PCAQT-qualified operator with a broad damp and waterproofing service range
- 10-year insurance-backed guarantees can be provided on request
- Substantial independent Checkatrade review history
Cons:
- The Southowram base may be less convenient for North or East Yorkshire
- As a sole trader, appointment availability may vary with workload
- Confirm the cost and terms of the insurance-backed guarantee before booking
Best for: West Yorkshire customers who want a highly reviewed independent operator with a broad damp-treatment service range.
Frequently Asked Questions
What Is the Average Cost of Damp Proofing in Yorkshire?
There’s no single figure, because cost depends on the property size, the type of damp, and the treatment needed – a small chemical DPC job is very different from a basement conversion. Most reputable firms in Yorkshire, including several on this list, quote only after a survey rather than publishing prices, which is generally a good sign that the price reflects your actual property. Expect to pay for a proper diagnosis rather than a guessed estimate.
How Do I Know if I Need a Damp Survey Before Booking Treatment?
If you can see tide marks, peeling paint, salt staining, a musty smell or spreading black mould, you have symptoms – but not necessarily a diagnosis. A damp survey should identify the likely moisture source before treatment is chosen. RICS guidance on damp and mould also stresses that moisture can come from several sources and should be investigated holistically. Book a survey whenever the cause is not obvious and before major works.
What Qualifications Should a Reputable Damp Proofing Company in Yorkshire Hold?
Look for membership of the Property Care Association (PCA), the trade body for damp and timber specialists, and surveyors holding relevant qualifications such as CSRT and CSSW. Those credentials indicate formal training and assessment. They are useful checks when comparing a specialist with a general builder offering damp work.
What Is the Difference Between a CSRT and CSSW Qualification?
CSRT, the former Certificated Surveyor in Remedial Treatment qualification, covers the diagnosis and treatment of damp and timber problems such as rising damp, condensation and wet or dry rot. CSSW (Certificated Surveyor in Structural Waterproofing) focuses on waterproofing structures below ground, including basements, cellars and tanking. A firm with both credentials on staff can cover everyday damp and more complex waterproofing.
Why Is a GPI Insurance-Backed Guarantee Important When Choosing a Damp Proofing Company?
A standard contractor guarantee depends on that contractor remaining in business. An insurance-backed guarantee is intended to continue if the contractor closes, subject to the policy terms. That can be valuable for landlords and buyers, but always check the insurer, duration, exclusions and whether the cover is transferable.
Choosing the Right Yorkshire Damp Specialist
When you strip it back, three practical checks matter most: verifiable qualifications, clear guarantee terms and coverage that genuinely reaches your town. Weigh those against your own property and the cause of the moisture.
Choose All Dry Damp Proofing if you’re in South or West Yorkshire and want a strong all-round option with PCA approval, qualified surveyors, broad services and an insurance-backed guarantee option. Choose thinkDRY for broad Yorkshire coverage, a free survey and an advertised 20-year guarantee. Dampcure Ltd is better suited to South Yorkshire and basement waterproofing than Leeds, while Leodis Damp Control offers a broad damp, timber and basement service across several Yorkshire towns. Damp2Dry Building Solutions Ltd suits Barnsley, Sheffield and Leeds projects needing follow-on building work; Home Building & Surveying Company is a nationwide treatment provider with wider property-preservation services; and MP Damp Proofing Services is a review-backed West Yorkshire independent. Whoever you shortlist, verify the attending surveyor’s qualifications and the exact guarantee terms before agreeing to work.
