What are the costs of supply for an increasing Damp Treatment?
The price of the materials required for the treatment of rising damp will be different based on the nature of the treatment.
For example, damp proof membrane costs around £1 to £5 per m 2 but around £1 to £3 per m 2 should do for a damp proof membrane in liquid form.
Plastic DPC on contrary, will cost you around £0.50 up to £1 per millimeter 2 in comparison to DPC injection cream will cost about £5-£7 per 100ml bottle. Anti-mold/moisture paint can be found for approximately £20-£30 for a tub.
A few things you need to know about…
It is best to delegate the majority of this task to a professional. However, some components may be suitable for DIY when you have the appropriate expertise and experience and know the steps to be taken to ensure safety.
You can finish painting or decorating after the initial work has been done or you could change the skirting boards in the room if required.
Both of these tasks can reduce your costs by £500 or £700 in all, based on the size of the work, as well as other things. If you are working using damp proof paint it is essential to take all safety precautions.
Other Jobs to Complement the treatment of Rising Damp
If you are having your damp treated for rising it is possible to cover the cost of additional work to be completed at the same time.
Here are some examples that are worth a look…
Painting and decorating

Once the damp wall has been sealed, you may wish to pay the professional to paint the room rather than taking it on DIY. Special damp proof paint will be needed.
The process would take about 6-12 hours per room. The cost for the room painted following treatment for the damp issue would be £250-£350 With wallpapering set to put costs around £350-£450..
Replacing Skirting Boards
In order for the rising dam to be effectively treated it is likely to be essential to have the decking replaced. Some of the skirting boards could be enough to remain on, but the majority of it is likely to be affected by decay. Skirting boards are priced between £1-£3 per meter.
This amounts to the total cost of £300-£400 in order to change the skirting board of an average space. If the labor cost is in addition to the cost of supply you could expect to cost between £350-£750 but it could depend on the skilled professional you hire in addition to other aspects.
Tradesmen’s Costs for Treatment of rising Damp
Now we’ll look at the labor costs associated with the treatment of the rising damp. This doesn’t include supply costs as well as any costs for disposal of waste.

However, those with a rising damp tend to establish the cost of labor depending on the task at hand, and thus the hourly and daily rates might not be applicable in the traditional sense.
Therefore, the above hourly and daily rates are only estimates. However, the amount you’ll be charged for a job per day or hour can differ dramatically.
When looking at the costs for labor of particular tasks for a rising damp specialist, it is likely that he will probably charge £800-£850 for the injection of DPC on one wall, with DJC injections for the entire home costing about £1,500-£1,900.
The labor cost for applying plastic DPC installed on one wall it will cost you around £200-£300 while similar work for a whole house priced between £800-£1,000.
In the case of having a damp-proof membrane installed and the labor costs will range from £700-£500 regardless of whether the work is done on a single wall or on a floor.
For a channel to be built along a wall, anticipate a labor charge of £300-£350, with the labor cost ranging from £500-PS700 for the channel dug across the whole house.
If you’d like to have a portion or a wall swept out, anticipate paying between £100-£150 or so.
You can clearly see that cost of labor can vary significantly, as can the actual cost of labour per hour/day.

“Wait what, then, is it because my place of residence matter to the labor cost, if it does? “
The fact is that the cost of labour varies throughout the UK. The factors that determine this be the price of living within the location and the level of competition, or lack of competition.
The cost for hiring a professional within the UK is generally more expensive throughout the Southeast (London particularly) and is generally lower for Northern England, Scotland and Northern Ireland.
How long does a rising Damp Treatment Last?
On average the process of a DPJ injection for a single wall will take about two to three days, while the same procedure for a whole house that takes between four and six days. For a typical plastic DPC job, anticipate to complete the task in 3 to 6 hours on one wall or the same amount of time for an entire residence.
Installing a damp-proof membrane, for a single floor or a wall is expected to take around 1.5 up to 2.5 days. The same timeframe could be applicable to the channel dug in the wall.
If you want to create a channel throughout the entire home you can expect the project to typically take between four to six days. The process of removing a piece of cavity wall it will take between 2 to 3 hours.
Factors that influence the timing of rising damp treatment are the size and nature of work as well as the severity of the damage and accessibility.
Rising Damp Treatment Timeline
|DPC Injection for Single Wall||2-3 Days|
|DJC Injection for All Buildings||4-6 Days|
|Plastic DPC for Single Wall||3-6 hours|
|Plastic DPC for Entire House||1-2 days|
|Damp Proof Membrane Installation for Wall or Floor||1.5-2.5 days|
|Channel Dug Along a Wall||1.5-2.5 days|
|Channel Dug Along an Entire House||4-6 days|
|Clearing Out Cavity Wall Section||2-3 hours|
Different types of Rising Damp Treatments
After we’ve examined the time frames and pricing that rise damp treatments, let’s take a look at each type in greater in greater detail. We’ll also review how much each of the rising damp treatments cost.
The most popular method of treating rising damp is through DPC injection(s). These injections provide an effective and long-lasting method of dealing with the rising dampness. Additionally, DPC injection offers a quick response to the issue that is at the moment.
DPC injections work by forming the appearance of a barrier to moisture. This barrier could be used to prevent the growth of dampness, and thus safeguard wall surfaces from damage.
It’s an affordable solution if you decide to go DIY and for instance, DPC injection cream costing at around £5-£7 for 100ml of product.
What are the negatives ?…
One drawback of DPC injections is the fact that they’ren’t suitable for application in stone structures. There’s also the risk of applying the product too much and making it useless.

- Not the best choice to treat stone walls
- It can be used to high levels and not work in a way that is correct
- A serious damage could be caused when a wall is glued in a way that is not done correctly
Damp Proof Membrane
Damp proofing membrane is made up of polyethene sheets made to block the flow of moisture. This kind or damp proofing course typically placed under concrete floors to prevent the floors from absorbing moisture through capillary action.
Damp-proof membranes could prevent damage from occurring to concrete during building activity in the future, albeit these membranes will prolong the duration required for the concrete to dry out.
One instance where you’ll want to consider damp-proof membranes is when you have underfloor heating installed beneath a surface of concrete.
It is worth noting it is important to note that the plastic DPC is a form of membrane that is damp-proof. In general damp proof membranes, they cost between £1 to £5 per millimeter 2, as well as the £1-£3 range per Liter if purchased with liquid forms.
- A great option for damp proof a concrete floor is to
- It is ideal if you plan to install heating underfloor underneath a concrete surface
- Provides concrete protection for the future construction activity
- The lengthens time required in order for the concrete to dry
Installing a drainage channel is among the most well-known methods to combat recurring rising dampness. It’s a method that permits the flow of water through (from an region) thus preventing the accumulation of water in specific areas.
The overall result of this system is that it can prevent rising dampness. It’s a commonplace for concrete paving stones or a gravel or concrete path to be laid along with the drainage channel.
The construction of a drainage channel can take several days if it is constructed on a wall or even longer if it is for the entire home.
The former would run approximately £280-£500 and you’ll need an amount between £500 to the £1,500 mark in the case of the latter. in both instances the cost would depend on the size and type of the home.
