Damp Proofing FAQs — South East Damp Experts | Essex & Suffolk

Question 1

How much does a damp survey cost in Essex or Suffolk?

Accepted Answer

We offer professional damp surveys across Essex and Suffolk. Survey costs vary depending on the size of the property and the nature of the problem, but we always provide a clear, no-obligation quotation before any work begins. Contact us for a free initial assessment.

Question 2

How much does damp proofing cost?

Accepted Answer

Damp proofing costs depend on the type of damp, the extent of the problem, and the size of the affected area. Rising damp treatment typically starts from a few hundred pounds for a single wall, while basement waterproofing projects can range into the thousands. We provide detailed, itemised quotations so you know exactly what you're paying for.

Question 3

Do you offer free surveys?

Accepted Answer

We offer a free initial telephone or video consultation to discuss your concerns. A full on-site damp survey carried out by one of our qualified CSTDB or CSSW surveyors is a paid service, but the cost is fully transparent and agreed in advance. The survey report provides a detailed diagnosis and recommended treatment plan.

Question 4

How long does a damp survey take?

Accepted Answer

A typical residential damp survey takes between one and three hours depending on the size of the property and the number of areas to be inspected. Our surveyor will carry out a thorough investigation using specialist moisture meters and thermal imaging where required, and will talk you through their findings on the day.

Question 5

How quickly can you carry out a survey?

Accepted Answer

We aim to book surveys within one to two weeks of your enquiry, though we can often accommodate urgent appointments sooner. Contact us to check current availability in your area.

Question 6

Will my home insurance cover damp proofing?

Accepted Answer

Most standard home insurance policies do not cover damp proofing as it is generally considered a maintenance issue rather than sudden accidental damage. However, if damp has been caused by a specific insured event such as a burst pipe or storm damage, your insurer may contribute. We recommend checking your policy and can provide a detailed report to support any insurance claim.

Question 7

What is rising damp?

Accepted Answer

Rising damp occurs when groundwater travels upwards through the pores and capillaries in a wall or floor. It is most common in older properties where the original damp proof course has failed, is absent, or has been bridged. Signs include tide marks on walls, peeling paint or wallpaper, salt deposits, and a damp or musty smell at low level.

Question 8

How do I know if I have rising damp?

Accepted Answer

The most common signs of rising damp are a horizontal tide mark on internal walls (usually no higher than one metre), white salt deposits on the wall surface, peeling or bubbling paint and wallpaper, and a persistent damp or musty smell. However, these symptoms can also be caused by other forms of damp, which is why a professional survey is essential for an accurate diagnosis.

Question 9

How is rising damp treated?

Accepted Answer

The standard treatment for rising damp involves injecting a chemical damp proof course into the base of the affected wall to create a new moisture barrier. The wall is then re-plastered using a salt-resistant render system. In some cases, external ground levels may also need to be reduced. All our rising damp treatments come with a long-term guarantee.

Question 10

Can rising damp be fixed permanently?

Accepted Answer

Yes. When correctly diagnosed and treated by a qualified specialist, rising damp can be permanently resolved. Our chemical damp proof course injection, combined with appropriate re-plastering, provides a long-lasting solution backed by our written guarantee.

Question 11

Does rising damp affect property value?

Accepted Answer

Untreated rising damp can significantly affect a property's value and saleability. Mortgage lenders and surveyors will flag active damp as a defect, and buyers may request a reduction in price or insist on treatment before exchange. Having a professional treatment carried out with a transferable guarantee can actually add value and reassure buyers.

Question 12

What is basement waterproofing?

Accepted Answer

Basement waterproofing (also known as tanking) is the process of making a below-ground space resistant to water ingress. This can be achieved using internal or external waterproofing systems, cavity drain membranes, or a combination of methods depending on the structure and intended use of the space.

Question 13

What is the difference between Type A, B, and C waterproofing?

Accepted Answer

Type A (barrier protection) uses waterproof coatings or membranes applied to the structure to prevent water entry. Type B (structurally integral) uses waterproof concrete or admixtures during construction. Type C (drained protection) uses cavity drain membranes to collect and manage water that enters the structure, directing it to a sump and pump. We design and install all three types and will recommend the most appropriate solution for your property.

Question 14

How long does basement waterproofing last?

Accepted Answer

A correctly designed and installed basement waterproofing system should last the lifetime of the building. We offer guarantees of up to 10 years on our basement waterproofing works, and the systems we install are designed to BS 8102:2022 standards.

Question 15

Can I convert my basement into a habitable room?

Accepted Answer

Yes, in many cases a wet or damp basement can be converted into a usable living space with the right waterproofing system. We can survey your basement and advise on the most suitable approach, taking into account the structure, water table, and your intended use of the space.

Question 16

What causes condensation and mould in my home?

Accepted Answer

Condensation occurs when warm, moist air meets a cold surface and the moisture condenses into water droplets. It is most common in poorly ventilated homes, particularly in kitchens, bathrooms, and bedrooms. If left untreated, persistent condensation leads to black mould growth, which can cause respiratory problems and damage to decorations and furnishings.

Question 17

Is black mould dangerous?

Accepted Answer

Black mould (typically Aspergillus or Cladosporium species) can cause or worsen respiratory conditions, allergies, and asthma, particularly in children, the elderly, and those with existing health conditions. It should be treated promptly. We can identify the root cause and recommend the appropriate ventilation or treatment solution.

Question 18

How do you treat condensation and mould?

Accepted Answer

Treatment depends on the severity and cause. Solutions range from improved ventilation (such as PIV units or extraction fans) to anti-condensation coatings and mould treatment products. We always address the root cause rather than simply treating the visible mould, to prevent it from returning.

Question 19

What is a PIV unit and does it work?

Accepted Answer

A Positive Input Ventilation (PIV) unit is installed in the loft and gently pushes fresh, filtered air into the home, displacing stale, moist air and reducing condensation. PIV units are one of the most effective and cost-efficient solutions for whole-house condensation problems. They are quiet, low-energy, and require minimal maintenance.

Question 20

What guarantees do you offer?

Accepted Answer

We offer up to 20-year guarantees on damp proofing and timber treatments, and up to 10-year guarantees on basement waterproofing works. All guarantees are backed by the Guarantee Protection Trust (GPT), which means they remain valid even if our company ceases to trade — giving you complete peace of mind.

Question 21

Are your guarantees transferable?

Accepted Answer

Yes. Our guarantees are fully transferable to new owners if you sell your property, which can be a valuable selling point and may satisfy mortgage lender requirements.

Question 22

Are you PCA members?

Accepted Answer

Yes. South East Damp Experts are full members of the Property Care Association (PCA), the leading trade body for the damp proofing and timber treatment industry. PCA membership requires surveyors to hold recognised qualifications (CSTDB or CSSW) and companies to adhere to a strict code of conduct.

Question 23

What qualifications do your surveyors hold?

Accepted Answer

Our surveyors hold the CSTDB (Certificate in Structural Waterproofing Design and Building Pathology) and CSSW (Certificate in Surveying Structural Waterproofing) qualifications, which are the industry-recognised standards for damp and waterproofing specialists. We are also BWPDA registered and members of the Federation of Damp Proofing Specialists (FOD).

Question 24
