Rising Damp Treatment Specialists

Independent Damp Surveys, Diagnosis & Proven Treatments

If you suspect rising damp in your property, you’ve probably already read conflicting advice online or been approached by a damp proofing company offering “quick fixes.” The truth is, rising damp is one of the most misunderstood and misdiagnosed building issues in the UK.

Our role as an independent rising damp company is simple:

Provide honest, expert surveys carried out by qualified specialists.
Identify whether the issue is genuine rising damp or another cause.
Offer clear, transparent advice and treatment options if necessary.
Save you from wasting money on unnecessary or ineffective damp proofing.

Whether you’re a homeowner, landlord, or buyer flagged with “rising damp found on homebuyer’s survey,” we can give you the professional advice you need.

What Is Rising Damp?

Rising damp is the upward movement of moisture from the ground into walls and floors. It happens when porous building materials — like brick, mortar, or stone — absorb groundwater through capillary action.

Left untreated, rising damp can:

Damage plaster, wallpaper, and paint finishes.
Cause timber decay in skirting boards, joists, and floorboards.
Leave unsightly tide marks and white salts on walls.
Create a musty smell and encourage mould growth.
Reduce property value and cause issues during surveys and mortgage applications.

Does Rising Damp Exist?

Yes, but it’s far less common than many damp proofing companies suggest. The idea that all damp problems are rising damp is a myth used to sell unnecessary chemical damp-proof courses.

True rising damp is usually linked to:

No damp-proof course (common in properties built before 1875).
Failed or bridged damp-proof course.
High external ground levels allow moisture to bypass the barrier.
Defective rainwater goods or drainage, introducing excess moisture.

This is why it’s vital to get a proper rising damp survey before agreeing to costly treatments.

Signs of Rising Damp

You may have rising damp if you notice:

Tide marks at the base of internal or external walls (usually up to 1 metre).
Salt deposits (white, powdery patches) are caused by groundwater salts.
Flaking or bubbling plaster, peeling wallpaper, or blistered paintwork.
Rotting skirting boards or decayed timber.
Persistent damp patches that don’t dry out.
Musty smells in affected rooms.

Many of these symptoms are also caused by condensation, leaks, or bridging, which is why professional diagnosis is essential.

Rising Damp Myths Debunked

There are many myths and misconceptions surrounding rising damp. Here are the most common:

Myth 1: All damp patches are rising damp.
Reality: Most damp issues are due to condensation, leaking gutters, or bridging.
Myth 2: A chemical damp-proof course fixes everything.
Reality: Without a correct diagnosis, chemical injections won’t solve the problem.
Myth 3: Free surveys save you money.
Reality: “Free surveys” are usually sales visits designed to upsell unnecessary treatments. A paid, independent survey protects you financially.
Myth 4: Old houses always have rising damp.
Reality: Many old properties are damp-free. Issues are more often linked to ventilation, drainage, or lifestyle factors.

How Rising Damp Is Diagnosed

A specialist rising damp survey is the only way to confirm whether your property is affected. Our surveyors use:

Electronic moisture meters (such as the MMS2) are used to measure moisture content.
Salt analysis to identify nitrates and chlorides carried by groundwater.
Visual inspection of walls, ground levels, and rainwater goods.
Bridging checks for plaster, render, or external ground levels, bypassing the damp-proof course.

This comprehensive approach ensures you get a true diagnosis — not a guesswork assessment or sales pitch.

How to Treat Rising Damp

If rising damp is confirmed, treatments may include:

1. Install a New Damp-Proof Course

A chemical damp-proof course is injected into the walls at low level.
Costs £50–£100 per metre.

2. Specialist Replastering

Damp-damaged plaster must be removed.
Replaced with waterproof render and finished with skim plaster.
Average cost for a 3-bed property: £3,000–£4,000.

3. Salt Neutraliser Application

Protects new plaster from salt contamination.
Ensures long-lasting results.

4. Additional Methods

Membrane or tanking systems.
Improved drainage or ground-level adjustments.
Repairs to gutters, downpipes, and drains.

We only recommend treatment if necessary — and only after all other potential causes are ruled out.

Rising Damp Cost

The cost of treating rising damp varies by property size and severity:

Survey: £190–£490 (deducted if treatment is carried out).
Chemical damp-proof course: £50–£100 per metre.
Full treatment including plastering: £3,000–£4,000 for a typical 3-bedroom home.

Cheaper quotes are often incomplete or poorly executed, leading to repeated problems. We prioritise quality and transparency over shortcuts.

Frequently Asked Questions

1. Does rising damp really exist?
Yes, but it is rare. Many so-called “rising damp” problems are actually condensation or bridging.

2. What causes rising damp?
Rising damp is caused when groundwater is absorbed into walls due to a missing, failed, or bridged damp-proof course.

3. How much does rising damp treatment cost?
Costs range from £50–£100 per metre for chemical injection, with full treatment (including plastering) averaging £3,000–£4,000.

4. Can I treat rising damp myself?
