Rising Damp Treatment

Rising Damp Treatment across Farnborough

Rising damp treatment in Farnborough. If you have a tide mark and blown plaster low down on a wall, the damp-proof course has usually failed. We put in a new one and make good.

We confirm it is genuinely rising damp with a survey first, because condensation and penetrating damp look similar in Farnborough homes but need very different work.

Every quote varies depending on the property and what the job needs, but here is what a typical rising damp treatment job in Farnborough covers from start to finish.

How we do it

Rising Damp Treatment in Farnborough: the process

  1. Step 01

    Confirm the cause

    We check it is rising damp and not condensation or a penetrating leak.

  2. Step 02

    Install the DPC

    A new chemical damp-proof course is injected along the base of the wall.

  3. Step 03

    Strip contaminated plaster

    Salt-laden plaster is removed so it cannot spoil the new finish.

  4. Step 04

    Replaster

    Walls are re-rendered with a salt-resistant system, ready to dry and decorate.

Rising damp treatment in Farnborough homes

Rising damp is the problem people worry about most and the one that is misdiagnosed most often. Genuine rising damp is far less common than the internet suggests, so every Farnborough survey starts with moisture readings rather than an assumption. Where it is rising damp, the fix is well established and permanent.

How to tell it is rising damp

Rising damp leaves a fairly even tide mark, usually somewhere between 600mm and a metre up the wall, with blown plaster and a white salty bloom just above it. It does not get dramatically worse after heavy rain, and it does not appear high up or in cold corners.

Condensation shows higher and in corners. Penetrating damp worsens with the weather and is usually one patch rather than a band. All three look similar in Farnborough homes and need completely different work, which is why the readings matter more than the appearance.

How rising damp treatment works

Rising damp treatment has two halves, and skipping either is why some jobs fail. First we install a new damp proof course: a water-repellent cream injected into a line of holes drilled along the mortar bed, which spreads through the mortar and cures into a continuous barrier.

Second we take off the salt-contaminated plaster above it and replaster with a salt-resistant render. Ground salts stay in old plaster and keep pulling moisture back to the surface, so a new course behind old plaster still shows damp patches months later.

The best rising damp treatment for your property

There is no single best rising damp treatment for every wall. Injected creams suit most solid masonry and are what we fit on the majority of Farnborough jobs. Very thick or rubble-filled walls sometimes call for a different approach.

Where the real problem turns out to be a bridged course, lowering raised ground levels or clearing a blocked cavity fixes it with no injection at all. We survey before recommending, because the best treatment is the one that matches the wall, and occasionally the honest answer is that you do not need a damp proof course.

Rising damp treatment cost in Farnborough

Rising damp treatment cost depends on the run of wall affected, how much plaster has to come off and whether skirting or floor timber needs replacing. A single wall is a modest job. A full ground floor with replastering throughout is a considerably bigger one.

We quote each Farnborough property after a free survey and set it out in writing before anything starts, so the rising damp treatment cost you are given is the one you pay.

Common questions

Rising Damp Treatment in Farnborough: your questions

How do I know it is rising damp and not condensation?

Rising damp leaves a salty tide mark at a fairly even height; condensation shows higher up and in corners. Our Farnborough survey settles it with moisture readings.

How long before I can redecorate in Farnborough?

New render needs to dry out before painting, usually a few weeks. We provide you with a guide for your Farnborough job so the moisture is fully out first.

What is rising damp treatment?

Rising damp treatment is the work that stops groundwater drawing up through a wall. In practice it means installing a new damp proof course, normally a water-repellent cream injected along the mortar bed, then stripping the salt-contaminated plaster above it and replastering with a salt-resistant render so the finish stays clean as the wall dries out.

How much does rising damp treatment cost?

It depends on how much wall is affected rather than a fixed rate per room. A single wall injected and replastered is a modest job; a full ground floor with timber repairs and replastering throughout is considerably more. We survey the Farnborough property free of charge and give you a fixed written quote before any work starts.

Does the whole room need doing?

Not always. We treat the walls that are affected and tell you honestly if the rest is sound.

How long does rising damp treatment take?

A typical wall is injected and replastered in one to a few days. We provide you with a clear timescale with the written quote.

Is rising damp treatment guaranteed?

Yes. The new damp-proof course is guaranteed, and we explain exactly what that covers before we start.
