Damp Proofing Surveys & Treatments

Have damp walls, peeling plaster or signs of rising damp? We investigate the cause, explain the right solution and can carry out appropriate damp-proofing and repairs.

DampServe provides paid specialist damp surveys, professional written reports and remedial damp proofing work. We inspect moisture problems for homeowners, buyers, sellers, landlords and commercial clients across much of England and Wales.

Not every damp patch needs a chemical damp-proof course. Condensation, penetrating damp, leaking gutters, high ground levels or bridging can cause similar symptoms. We identify the likely cause first, then recommend repairs or treatment only where the findings justify them.

Our standard survey reports normally include a quotation for suitable remedial work where needed. You can also request a report without a treatment quotation when booking, and there is no obligation to instruct DampServe for repairs.

What kind of damp problem do you have?

You don't need to know the technical term before contacting us. These are some of the issues we investigate before deciding whether damp proofing is necessary.

01 · Low-level damp

Suspected rising damp

Damp or damaged plaster near floor level may have several causes, including a bridged or ineffective DPC, salts or other moisture sources.

02 · Rainwater ingress

Penetrating damp

Rain entering through roofs, gutters, brickwork, render or faulty pointing can cause staining, mould and damaged finishes.

03 · Moisture in the air

Condensation & mould

Cold surfaces, poor airflow and excessive humidity may cause black mould or water collecting around windows and external walls.

Condensation investigations →
04 · Building defects

Leaks, bridging & salts

High paths, leaking pipes, blocked gutters and salt-contaminated plaster can mimic more serious damp problems.

Understanding damp proofing

What is damp proofing — and when is it needed?

Damp proofing describes measures used to prevent or control moisture affecting a building. Depending on the diagnosis, the solution might involve a damp-proof course, a specialist membrane, plaster repairs or simply correcting a defect that allows water in.

For example, injecting a new DPC will not solve a leaking gutter or condensation. Equally, where a DPC-related defect is supported by evidence, a properly designed damp-proofing treatment may be appropriate.

We assess the property, explain the options and identify whether local repairs, moisture control or specialist treatment is the sensible route.

Remedial work from DampServe

We don't just survey — we can carry out the work too

When the findings show that damp treatment or repair is needed, DampServe can provide a quotation for appropriate remedial work and undertake the work you choose to instruct.

Depending on the property and diagnosis, our work may include damp-proof-course treatment, targeted damp repairs, removing bridging, suitable plaster removal and replastering, moisture-related timber repairs and other building remedial measures.

We also inspect associated problems such as woodworm, wet rot and dry rot, and offer appropriate treatments and repairs under our specialist services.

A survey does not oblige you to buy treatment

The survey fee pays for our professional assessment and written report. Our normal report includes a quote for suitable necessary work, but you are free to use another contractor or request a report without our treatment quotation.

A straightforward process

From damp survey to the right repair

Whether you're worried about damp at home or have been asked for a specialist report, we start by establishing what the building actually needs.

1

Tell us what's happening

Send the property address, a brief description and photos if available. We will discuss the survey and provide its fee before booking.

2

Inspect and report

We investigate accessible areas, interpret the evidence and provide written findings with proportionate recommendations.

3

Decide about any work

Our standard report normally includes a quotation for necessary suitable work. You choose whether DampServe carries it out.

Why diagnosis comes first

The right treatment depends on the cause

A damp wall does not automatically need chemical damp proofing. We look at ground levels, external defects, ventilation, moisture patterns, plaster condition and other evidence before making recommendations.

Where the issue is minor, historic or maintenance-related, the report should say so. Where remedial work is appropriate, we explain what needs doing and why.

The survey is a paid professional service; the option to carry out work is separate. This keeps our inspection process transparent and lets you decide how to proceed.

Two ways to commission a report

Standard damp survey: written findings and recommendations, normally with a quotation for necessary appropriate treatment or repairs.

Report without treatment quotation: written findings and recommendations without a DampServe remedial quotation, when requested before booking.

The written survey

What your damp proofing survey may include

Every property is different. Within the agreed scope and accessible areas, we aim to give you a clear basis for deciding on treatment or repairs.

Inspection and reporting

  • Damp symptoms and moisture patterns
  • Relevant moisture readings and interpretation
  • External ground levels and DPC bridging
  • Gutters, roofs, render, pointing and drainage defects
  • Condensation and ventilation considerations
  • Plaster, salt and visible timber concerns
  • Photographs and clear written observations
  • Likely causes, limitations and recommendations
  • Remedial quotation where needed and appropriate
  • Options for monitoring or targeted repairs

Buying or selling a property?

If a HomeBuyer Report, surveyor or lender has raised damp concerns, you may need a more formal pre-purchase damp and timber report.

We also provide reports for sellers, homeowners, landlords and commercial properties. Please share any requirements from the party requesting the report.

Damp survey costs and treatment quotations

The inspection fee and the cost of any remedial work are different. We explain the survey fee before you book, then determine what work, if any, the property needs.

How much does a damp survey cost?

The fee varies by property size, location, access and the report you require. Our main cost guide provides indicative pricing for domestic damp and timber reports.

DampServe surveys are not free. You pay for the inspection and written findings, even where no treatment is required.

How much does damp proofing cost?

Costs depend on the confirmed cause, extent of damage and appropriate solution. Replacing damaged plaster or correcting a local defect is very different from a designed damp-proofing system.

We normally include a quotation for necessary appropriate work in our standard report, so you can make an informed decision.

Frequently asked questions

Damp proofing surveys and treatment FAQs

Answers about rising damp, treatment options, paid surveys, reports and quotations.

Do I always need damp proofing if I have damp walls?

No. Damp patches can be caused by condensation, plumbing leaks, penetrating damp, bridged damp-proof courses, high ground levels or external building defects. We investigate the cause before recommending treatment.

Can DampServe carry out damp proofing and replastering?

Yes. As well as paid damp surveys and reports, DampServe can quote for and carry out suitable damp-proofing, plastering, targeted repairs and other appropriate remedial work.

What is the difference between a damp survey and damp proofing?

A damp survey investigates the source and extent of the moisture problem. Damp proofing is one possible response where the findings justify it; other properties may need maintenance, ventilation improvements or local repairs.

Do I need a new damp-proof course?

Not necessarily. Some properties have a bridged or otherwise compromised existing DPC. Others have condensation, leaks or penetrating damp rather than a defective damp-proof course. A new DPC should follow a proper diagnosis.

How much does a damp proofing survey cost?

Fees depend on the property, location, access and reporting requirements. See our survey pricing guide or contact us with your address and details for a survey fee quotation.

Will you include a quotation for treatment in my report?

Our standard reports normally include a quotation where suitable remedial work is genuinely required and can be priced. You have no obligation to instruct DampServe to do the work.

Can I request a report without a treatment quotation?

Yes. Let us know when you book if you want the survey and report without a DampServe treatment quotation.

Can I get a free damp survey instead?

Some contractors offer free inspections to assess work and prepare quotations. DampServe charges for a professional inspection and written report. The purpose and detail of the two services may differ.

Do you provide reports for homebuyers and mortgage-related cases?

Yes. Please send the wording requested by a surveyor, lender or solicitor before booking. The scope can be agreed, but the requesting organisation determines its own report acceptance requirements.
