Damp is an issue which affects many properties, contributing to potentially severe damage, not to mention health implications for those living in a damp home.
Fixing damp can be expensive. The average cost of damp proofing a three-bedroom semi-detached house is around £4000. However, damp can also be rectified with straightforward and affordable solutions once you know the different types of damp proof treatment costs, and the type of damp you’re dealing with.
In this guide, we’ll discuss the damp proof course costs of varying methods, as well as what factors affect damp proofing costs and what’s involved in the cost to damp proof a house.
What Is Damp Proofing?
Damp proofing, also known as a damp proof course, is a method of creating a barrier between moisture and an interior space, such as a wall or floor. There are different ways that damp can affect your home:
- Rising damp – this occurs when moisture travels upwards through walls via capillary action. Rising damp can cause extensive damage, including deteriorating plaster, paint, wall stains, visible wet patches, and external crumbling mortar. It’s important to treat rising damp as it can cause serious structural issues which are expensive to repair. Get your rising damp fixed now.
- Penetrating damp – this occurs when water infiltrates through an external wall, floor, or roof. Get a quote for your penetrating damp in East Midlands.
- Condensation – this is caused by having too much moisture within your home or when warm air and cold air meet. Water vapour turns into a liquid known as condensation.
There are varying types of damp proofing depending on the severity of damp within your home and where it’s located. When researching damp treatments, you may be wondering ‘how much is a damp proof course?’
Let’s take a look at the damp proofing cost for varying methods.
Cost of Damp Proof Injection
A damp proof injection is inserted into an internal wall to prevent rising damp. The cost of damp proofing one wall with this method is around £280 while the damp proofing cost per metre is around £70.
However, you can purchase damp proof course creams from around £15 and do it yourself.
Obviously, if you have rising damp that has damaged the plaster and wall décor, you’ll need to factor in those costs too.
Cost of cavity wall damp proof course
A cavity wall damp proof course involves placing a barrier material between the bricks and the ground to prevent moisture from rising upwards. If your home has a damp proof course that has failed, this could be costly as it may be that the ground level is above the damp proof course in the wall, causing it to be ineffective.
To rectify this, the external ground needs to be lowered by digging up the earth, covering it with slab or soil. The cost of this is around £500 for a semi-detached house and up to £1500 for a detached property.
If you’re planning on converting your cellar into a livable space, damp proofing a cellar costs between £40 to £80 per square metre if it’s performed via tanking.
Cost of chemical injection
Chemical injection involves drilling holes into the brickwork of a wall and spraying a chemical into them. This prevents damp from rising up the walls. The chemical damp proofing cost can start from around £370 for a terraced house up to £2000 for a detached house. Additionally, there’s the cost of painting and decorating to consider on top of this fee. You can save money by completing this work yourself, but you’ll need to purchase tools, paint, wallpaper etc.
Cost of damp proofing penetrative damp
If you have an old home, the cost of damp proofing an old house will depend on the extent of the damage. If the penetrative damp is caused by a leaky roof, the cost to replace tiles could be around £100, whereas a faulty uPVC window could cost around £500 to be fixed.
Cost of damp proofing a basement
If you have damp in your basement, you can start to dry it out via fairly affordable methods. Basement damp proofing costs can start by investing in a dehumidifier to reduce the level of moisture in the air. It’s also a good idea to ventilate your home by opening a few windows or running a fan to help improve air circulation. Inspect external features of your property, including drainage and walls to determine if any water is leaking into your basement.
What Affects The Cost Of Damp Proofing?
Is damp proofing expensive? That’s what many people want to know when contemplating damp proof course costs. Several aspects impact damp proofing costs, including:
- House size – a bigger house will cost more than a smaller property depending on the scale of the problem
- Size/scale of the damp – more damp will require more treatment
- Severity of the damp problem – if structural repairs are needed, the cost is likely to be more expensive
- Repairs needed – if both external and internal treatment is needed, the cost could be more expensive
- Redecorating costs – plaster, paint and wallpaper will add to the cost of treatment
- Age of the house – old houses may need more damp proofing than new builds
