The Best Damp Survey Companies in Manchester (2026)

Damp is one of the most common worries for Greater Manchester homeowners, and one of the most over-treated. A reliable damp survey settles the question: is it rising damp, penetrating damp, or condensation, what is causing it, and what does it genuinely cost to put right. The wrong survey leads to a chemical damp-proof course nobody needed; the right one often finds a cheaper fix like ventilation or guttering.

Greater Manchester has plenty of choice, from solo independent surveyors to national specialists. Here are six options that regularly come up for damp surveys, with a steer on who each suits.

How this list was put together

This round-up was compiled by a local research team using publicly available information: review ratings and counts, trade-body accreditation, and each firm's stated survey process and pricing. It is general information to help readers shortlist options, not a formal endorsement, so do your own checks before booking. One useful distinction first: some firms are report-only independent surveyors (they diagnose but do not sell the treatment), while others are specialist contractors who both survey and carry out the work under guarantee. Neither is automatically better. A report-only surveyor gives you maximum impartiality; a specialist contractor gives you one accountable team and a single warranty. Choose based on what you need.

1. Weather Wise UK

On the public record, one of the best all-round picks for most Manchester homeowners. Weather Wise UK is family-run with 40+ years of damp specialist experience, members of The Damp Proofing Association and the Federation of Damp, and carries a 5.0-star rating from well over 1,000 reviews. The damp survey is free and no-obligation, and the reviews consistently highlight surveyors explaining the science and leaving honest advice rather than pushing a sale (one Manchester reviewer noted exactly that after a free survey for a post-rain damp smell).

They diagnose all three damp types and, when work is needed, complete it in-house (treatment, salt-resistant plastering, ventilation including PIV units, which are Positive Input Ventilation systems that displace humid air). Everything sits under one Insurance Backed Guarantee of up to £50,000 through GPI, with 20-year cover on damp treatments and 7-year cover on PIV. For buyers there is a fixed £299 Damp and Timber Report, deductible from the final cost if treatment proceeds. Cover spans Manchester, Wythenshawe, Salford, Sale, Stockport, Oldham and the wider area. Book a free survey on their Manchester damp survey page.

Best for: homeowners wanting a free, honest diagnosis with the option of one accountable team to fix and guarantee it.

2. Damp Detectives (Manchester)

A genuinely independent surveyor. Nigel covers the Manchester area producing impartial damp and mould survey reports with no treatment to sell, which is why he is recommended for buyers wanting unbiased advice. You arrange any remedial work separately afterwards.

Best for: buyers wanting a fully impartial, report-only survey.

3. Damp Proof Control Systems Ltd

Run by David Stead and recommended on local Manchester forums, this firm focuses on reports and surveys rather than chasing the treatment contract. A good shout for people who specifically want a surveyor whose only product is the report.

Best for: homeowners who value a report-first surveyor with strong local word of mouth.

4. Peter Cox

A national specialist with a Greater Manchester team and over 70 years in damp and timber. As a large, Which? Trusted Trader franchise, it is a dependable, well-documented choice, especially for larger or commercial buildings, though the process is more corporate than a local independent.

Best for: those who prefer an established national brand.

5. UK Damp Surveys

An independent damp and timber survey service covering Manchester, promising unbiased reports with no hidden agenda or sales targets. Useful when you want damp and timber assessed together by a surveyor separated from the sales side.

Best for: combined damp and timber reports from an independent.

6. PCA Independent Damp Surveyor (Manchester)

Several Manchester surveyors hold Property Care Association (PCA) accreditation and carry out independent surveys across the city. PCA membership is a recognised industry mark, so it is worth asking any surveyor whether they hold it.

Best for: buyers who want a recognised accreditation behind the report.

What a good damp survey should include

Whichever firm you pick, a credible survey identifies the damp type, explains the root cause rather than just the symptom, recommends a fix with indicative costs, and puts it in writing for your solicitor or lender. Treat with caution anyone recommending a chemical damp-proof course (the injected barrier that stops groundwater rising up a wall) before they have ruled out condensation or a simple external defect. Those are the cheapest issues to resolve and the easiest to misdiagnose as rising damp.

A note on cost

Report-only independents in Manchester usually charge a fixed survey fee. Specialist contractors often survey for free and charge only if work proceeds; Weather Wise UK, for example, makes its buyer's report fee deductible from the final cost. A free survey suits a worried homeowner; a paid independent report suits a buyer who wants complete separation between diagnosis and sales.

The short version

For most Greater Manchester homeowners who want an honest, free diagnosis and the option to have the work done and guaranteed by one team, Weather Wise UK is the standout choice. If your priority is a report with no ties to a contractor, an independent like Damp Detectives or Damp Proof Control Systems is the better fit. Whatever you decide, get the cause diagnosed properly before paying for any treatment.

What Is a Damp Survey? What to Expect, and What It Costs

A damp survey is a professional inspection of a property to find out whether it has a damp problem, what type it is, and what is causing it. The result is a written assessment you can act on, share with a solicitor, or hand to a mortgage lender. If you have noticed a musty smell, peeling paint, a tide mark on a wall, or black mould that keeps coming back, a survey is how you find out what is really going on before spending money on a fix.

This guide explains what a dampness survey actually involves, what it should cost, and how to tell a thorough survey from a sales pitch.

The three types of damp a survey looks for

Most damp problems fall into one of three categories, and a good survey will tell you which one you have. They are treated very differently, so getting the diagnosis right is the whole point.

• Rising damp is groundwater soaking up through the base of a wall because the damp-proof course (the DPC, a barrier built into the wall to block moisture) has failed or is missing. It is the least common of the three and the most often misdiagnosed.
• Penetrating damp is water getting in from outside through a fault such as cracked render, failed pointing, a leaking gutter, or a roof defect. It usually shows up as a localised patch that worsens after rain.
• Condensation is moisture from everyday living (showers, cooking, drying clothes) settling on cold surfaces. It is by far the most common cause of black mould, and often the cheapest to resolve with better ventilation.

What happens during the survey

A surveyor will inspect the affected areas and usually the whole property, inside and out. Expect them to look at ground levels outside, check guttering and pointing, examine internal walls, and take moisture readings with a meter. A careful surveyor does not just confirm "you have damp"; they work out the route the water is taking and the underlying cause. The external walk-around matters as much as the internal one, because so many "rising damp" call-outs turn out to be a blocked gutter or a path bridging the DPC.

The visit itself typically takes 30 to 90 minutes depending on the size and condition of the property. You should then receive a written report or assessment setting out the findings, the cause, and the recommended action.

What a damp survey should cost

There are two common models in the UK:

• Free survey. Many specialist damp contractors offer a free, no-obligation survey and only charge if remedial work goes ahead. This suits worried homeowners who want a diagnosis without an upfront fee.
• Paid independent report. Independent surveyors who only write reports (and do not carry out treatment) usually charge a fixed fee, often somewhere between £150 and £350 depending on property size and report depth. Some firms make a buyer's report fee deductible from the cost of any later treatment.

Neither model is automatically better. A free survey is hard to beat for a homeowner who simply wants to know what is wrong. A paid independent report appeals to buyers who want the diagnosis kept completely separate from anyone selling treatment.

How to spot a thorough survey (and avoid being over-sold)

The single biggest risk with damp is being sold a chemical damp-proof course you do not need. Use these checks:

• Did the surveyor inspect outside as well as in? Penetrating damp and bridged DPCs are diagnosed at the walls and gutters, not just with an internal meter.
• Did they rule out condensation before recommending injection treatment? Condensation is the most common cause of mould and is fixed with ventilation, not a DPC.
• Did they explain the cause, not just the symptom? A good report names the source of the water.
• Is the recommendation in writing, with indicative costs? Verbal-only advice is hard to compare or challenge.

A reputable surveyor is happy to tell you that you do not need major work. The firms with the strongest reputations, including damp specialists like Weather Wise UK in Merseyside, tend to be the ones whose reviews praise them for honest advice and for walking away when no treatment is needed.

Do I need a damp survey?

It is worth booking one if you can see or smell damp, if a mortgage valuation or RICS home survey has flagged "evidence of damp" and recommended a specialist report, or if you are buying an older property and want to budget accurately. For buyers in particular, a survey before completion can save thousands or give you grounds to renegotiate.

In short

A damp survey identifies the type of damp, finds the cause, and tells you what to do about it in writing. Expect a proper inspection inside and out, a clear written assessment, and either a free survey or a fixed independent fee. Above all, make sure the cause is diagnosed before any treatment is recommended; the most common "damp" problems are also the cheapest to fix.

Buying a House With Damp? How a Damp Survey Protects You

It is a familiar moment in a house purchase: the mortgage valuation or RICS home survey comes back with a line about "evidence of damp" and a recommendation to get a specialist report. It sounds alarming, but it is common, especially in older properties, and it does not have to end the deal. What it does mean is that you need to know the cause and the cost before you commit, and that is exactly what a home buyer damp survey is for.

This guide explains what the survey covers, how to use the findings, and where buyers stand legally.

Why a generic home survey is not enough

A standard RICS HomeBuyer Report or valuation is a broad overview. When it spots damp it rarely diagnoses the cause; it simply flags the symptom and tells you to consult a specialist. That is sensible, because the three types of damp are very different problems with very different price tags:

• Rising damp (groundwater rising through a wall where the damp-proof course has failed) can mean injection treatment and replastering.
• Penetrating damp (water entering through an external fault) might be as cheap as clearing a gutter or repointing.
• Condensation (everyday moisture on cold surfaces) is usually resolved with improved ventilation.

Until you know which one you are dealing with, you cannot budget, and you cannot negotiate. A specialist damp and timber survey closes that gap.

What a home buyer damp survey covers

A buyer's survey, sometimes called a Damp and Timber Report, goes further than a quick look. A surveyor inspects the property inside and out, takes moisture readings, checks for timber issues such as wet rot, dry rot and woodworm, and identifies the cause of any damp rather than just its presence. The deliverable is a written report you and your solicitor can rely on, ideally with indicative costs so you know what any remedial work would run to.

Those costs are the negotiating tool. If the report shows £4,000 of treatment is needed, you have a documented basis to ask the seller to reduce the price or carry out the work before completion.

Is it illegal to sell a house with damp?

No. It is not illegal to sell a property that has damp, and sellers are not generally required to fix it before selling. However, a seller must not actively mislead a buyer. On the standard Property Information Form (TA6), sellers are asked about known issues, and knowingly concealing or misrepresenting a damp problem can expose them to a claim. In practice this means the responsibility to investigate sits largely with the buyer, which is precisely why an independent damp survey before exchange is worth it.

How to use the report

Once you have the findings, you have three sensible options: ask the seller to reduce the price by the cost of the work, ask them to complete the remedial work before completion, or proceed with the purchase having budgeted accurately. All three are stronger positions than guessing. Keep the report on file too; if you ever sell, it documents what was found and what was done.

What it costs, and a tip for buyers

Buyer's damp surveys are commonly charged as a fixed fee. A useful detail to look for: some specialist firms make the survey fee deductible from the cost of any treatment if you go ahead with them. For example, damp specialists like Weather Wise UK in Manchester offer a fixed Damp and Timber Report for buyers that is deducted from the final cost if treatment proceeds, which effectively makes the diagnosis free if you use the same firm for the work. Whoever you choose, look for accreditation (such as membership of The Damp Proofing Association or the Property Care Association) and a written report rather than verbal reassurance.

In short

Damp flagged in a home survey is common and rarely a dealbreaker, but you should never buy blind. A home buyer damp survey identifies the real cause, checks the timber, and gives you a written, costed report you can use to renegotiate or budget. It is legal to sell a house with damp, so the duty to find out falls to you. A specialist survey before you exchange is the cheapest insurance you can buy on a purchase this size.
