How Much Does Damp Proofing Cost In 2022?

Damp is one of the most common problems in homes and other buildings in the UK. This is due to our temperate climate which means that we have cold, wet winters and warm, wet summers.

Our homes bear the brunt of all that wet weather and suffer from a range of different types of damp problems which if not dealt with can escalate and cause damage not only to your property but to your health too.

The costs of damp proofing vary enormously depending on the type of damp and the size and type of home/building. Prices start at around £200 but can also be in excess of £5000 including expenses for fixing the damage that has been done and required additional work, such as redecorating or paving stone installation.

What is Damp Proofing?

Damp proofing is a system of treatments that help stop all the different types of damp from invading your home or building. From small changes to the outside of your property such as creating or improving the damp coursing or putting damp proofing silicone in the wall cavities.

Types of Damp

Rising Damp

This is characterised by tide lines up your walls. It happens when groundwater seeps up from the ground into the structures/walls of your home.

Penetrating Damp

Identified by cold walls, damp walls and black spotty mould especially higher up on walls within your home penetrating damp is caused by water seeping in through the outside walls of your property.

Condensation

Many of our day to day activities cause condensation, cooking, showering and even breathing all create moisture in the air inside our homes. If this moisture is not allowed to escape via adequate ventilation then condensation build-up can cause walls and ceilings to become damp.

Cost Factors of Treating Damp

Some of the factors that will affect the cost of treating damp include the type of damp being dealt with and the size of the area to be treated and the size and style of your home. Other costs also need to be factored in including the extent of the damage caused and whether areas will need to be replastered or redecorated.

  • For ground excavation to help eliminate rising damp the costs can go from £200 for one wall in a terraced home to over £4000 for a whole detached house with the addition of concrete slabs.
  • For the replacement or addition of damp proof coursing the costs can range from around £300 to over £2000.
  • To inject silicone damp proofing into walls the cost starts at around £500 for one wall of a terraced home to over £5000 for all the walls of a detached home.

What Happens When You Leave Damp Untreated?

Damp proofing costs can seem high. However, the price you pay for leaving damp issues unchecked can be much higher.

Unchecked it can lead to not just aesthetic damage to your home and furnishings but can in time cause structural damage. It can also be very unpleasant to live with causing bad smells and exacerbating health issues like asthma.

What is Water Ingress?

Water ingress is another name for penetrating damp. It can cause a variety of problems in your home and there are a number of potential causes.

To avoid water ingress causing further potentially costly damage and leading to health problems it is important to get it sorted out as soon as you notice the problem.

This article will alert you to the signs of water ingress that you need to look for, what the causes of water ingress are so you can avoid it, and also what you can do to treat it.

What is Water Ingress?

Water ingress or penetrating damp is when water/damp infiltrates a buildings structure. It is one of the most common causes of damp related problems in the UK.

Water Ingress vs Water Egress

The difference between water ingress and water egress is simple whether you are talking about water entering or exiting a building. Ingress is about water entering a building so covers things like adequate damproofing. Egress is exiting so covers things like adequate ventilation. However, water ingress as a term tends to cover both.

Signs of Water Ingress

Some of the signs that your home or building may have water ingress include:

  • Mold on walls and ceilings.
  • Damp patches.
  • A musty smell.
  • Paint and/or plaster peeling and coming away.
  • The property is difficult to heat or doesn’t stay warm.
  • Walls feel very cold to touch.
  • Woodworm (as woodworm like wood that has been exposed to damp).
  • Dry rot.
  • Wet rot.

What Causes Water Ingress?

There can be many causes of water ingress including the following:

  • Leaks in pipework or plumbing around the building.
  • Badly maintained, broken or full/dirty guttering.
  • Damaged mortar.
  • Missing or faulty damp proof coursing.
  • Faulty or aged window flashing.
  • Blocked air bricks.
  • Missing or inadequate waterproofing in the wall cavity.
  • Roof damage such as broken or missing tiles or worn out or damaged flashing.
  • Wall/brickwork damage – this can be from age or frost damage among other things.
  • Insufficient damp proofing in the cellar/basement.

How to Prevent Water Ingress

Staying alert to signs of damp and ensuring a building is well maintained is a good start to preventing water ingress.

Priotritisng waterproofing and ensuring additional waterproofing is added such as installing damp proof coursing and waterproof cavity wall insulation.

How to Treat Water Ingress

If you notice any signs of damp and water ingress it is important to uncove the source of the problem as quickly as possible to keep the treatment costs as low as possible.

If you cannot quickly discern the cause yourself then contact a damp proofing expert to come and assess the building.

Any repairs that are required should be attended to as quickly as possible.

The areas affected by water ingress will need time to thoroughly dry out professionals tend to use fans, dehumidifiers, to suck and the water and keep the air circulating.

Once the areas affected are dried out the repairs can be finished.

How To Identify Dry Rot Fungus

Dry rot fungus is a serious problem. Left untreated it can eat its way through all the wooden structures in your home seriously weakening flooring, roof beams, stairs and any other wood in your property leaving it dangerous and inhabitable.

Luckily it can be treated and if caught early you can escape serious damage. It is, therefore, important to educate yourself about what is dry rot, the causes and early signs of dry rot, and its progressive stages. This guide will help you to do that as well as go through some of the wood rot treatments that are available.

What is Dry Rot?

Dry rot is a type of fungus called Serpula lacrymans that thrives in damp wood. It can spread throughout your home easily because it can travel through masonry as well as wood.

Despite the name dry rot, wood needs quite a high water content for this type of fungus to take hold. The name stems from it being found in ‘dry’ or seasoned wood, in other words, timber that is ready for use in building, furniture or other industries.

Dry Rot vs Wet Rot

Dry rot and wet rot are two different types of fungus. Dry rot is Serpula Lacrymans and wet rot is Coniophora Puteana.
Of the two, dry rot spreads more easily and therefore is more of a threat to your property. Wet rot though still damaging usually remains more localised.
Both of these fungi thrive in wet conditions with dry rot taking hold in wood with a water content of 20-30% but wet rot, true to its name, requires a higher water content of around 50%.

What Causes Dry Rot?

A mix of airborne spores of the dry rot fungus and water causes dry rot. Therefore leaking pipes, leaking appliances, faulty guttering, condensation, penetrating damp, and broken roof tiles among other things can be the start of dry rot problems.

Stages/Signs of Dry Rot

Damp Smell

A damp musty, mouldy smell can be an early indicator of dry rot.

Spore Dust

The spore dust of Serpula Lacrymans is typically orange, rust-coloured or brown. If these spores come into contact with wood with a suitable water content dry rot will develop.

Hyphae

Once the spores have found the right conditions, i.e. damp wood, they grow into grey hair-like strands called hyphae. These penetrate and grow through the wood.

Mycelium

Similar in appearance to cotton wool mycelium grows from the hyphae. It is the mycelium that spreads looking for more wood to devour and can even travel across masonry (though it does no damage).

Timber decay

Wood that is dry, crumbling and/or cracks in square or rectangular patterns is likely to have a dry rot problem. It is better to get the dry rot problem treated well before it gets to this late stage when timbers in your home may need intensive work or replacement.

Sporophore

The mushroom or fruiting body of the dry rot fungus is round and flat, like a thick plate and is an orange and/or rusty red colour. They can appear in many different sizes, in extreme cases, they have been seen at over 2m in diameter.

Treatment for Dry Rot

If you suspect that you may have a dry rot problem in your home the first thing to do is get a survey to confirm that is the issue. Once the presence of dry rot has been confirmed then dry rot treatment can commence.
The first step is the find the source of the damp and get that issue resolved. Otherwise, the dry rot will recur. Once your home is adequately damp-proofed then all the affected wood will need to be removed.
All the existing wood in the property will then need to be treated with a fungicide.
