New technology in chemical Damp courses. How to choose a good damp specialist. Hi- I have just bought an old edwardian era terrace house with damp problems in the rear extension. It is single brick wall with no cavity and a solid concrete floor. It had some fairly disgusting wooden cladding all the way round the kitchen.
WHen I removed this I discovered damp and flaking brickwork between The house hasnt been lived in for at least several months. I am unsure if this is condensation or if there is some bridging going on around the concrete floor. Any thoughts would be appreciated Thanks Andrew.
Single skin has no insulation value so condensation will always be a problem. However, it has been unoccupied so without people bathing washing and cooking, the humidity will be a lower other than in a cold snap.
Penetrating damp is also more likely with single skin. Rising damp too if the concrete floor is higher than the DPC — if there is one. Ground levels at, above or within mm of the internal floor will increase rainwater penetration along the base or even bridge the DPC.
A dry lining system, independent of the walls or over a vertical membrane will present a dry service for decoration and could allow some insulation to be added too? But do check the external obvious issues first — pointing, ground levels, gutters and such. Hi Bryan, Very good article with clear explanation especially to people like me who are familiar with medical jargon and everything related to housing is like greek and Latin.
I recently moved in to a house and in utility room an done wall in kitchen there was some wetness and peeling of paint near the skirting board. One person came to have a look at it and suggested chemical injection.
Is it a common intervention and effective one? Rising damp is the only thing which a chemical DPC will control effectively. Rising damp does not result in water on the surface of plaster or paint. Has the utility an effective extractor fan installed? This is essential. If not, fix that first and then condensation should be reduced. Prices vary based on the thickness of the walls — the length and of course the amount of re-plastering needed, so it is very hard for me to give you guidance.
DPC work can run into thousands on larger jobs so get more than one quite and make sure you do your homework to get a good installation.
If a DPC is required make sure that you use a contractor who is a member of the PCA and ask them for a guarantee with guarantee Protection Insurance cover. This will avoid the problem of being left with a useless guarantee should another recession wipe-out the contractor, before the 20 year guarantee has expired.
I am in the process of buying a property and have just discovered that it was treated DPC for rising damp and wood boring infestation in the roof area in which I think had previously been treated with a 30 year guarantee. Financially, this seems to me to be a nightmare. Are these problems likely to reoccur in the future? Can you advise on who I need to contact for expert advice.
I am currently overwhelmed by it all. It is very likely that the issue is old news if the roof has been treated before. As a buyer you should make sure that the house is surveyed by someone working for you — not the vendor. You can get an independent surveyor, consultant or a specialist contractor.
I would go for a contractor firts as that will be cheaper and if there is anything wrong he can give you a quote for the repairs, so that you can negotiate with the vendor on the costs. If ther are any guarantees call the firm to make sure they are still trading and are not in dispute with the vendor or anything — get them to assign any guarantee to you. Dear Bryan, I have an internal wall with rising damp. There was no rising damp when I bourght it 20 years ago, the problem seemed to start after I had the central heating put in.
I have been advised that the bitumen DPC may have corroded and the solution is to have a chemical DPC injected which does seem sensible to me, however, after reading your guidance I am starting to wonder if the DPC has indeed corroded and if so why would that happen only in this one part of the house? In some very rare cases, water can travel beyond this point. The height the water reaches depends on several key factors. These include the pore structure of the bricks and mortar and the rate of evaporation.
Masonry containing a high proportion of fine pores will allow the water to rise higher than one with less pores. Rising damp can occur up to 1. The water from the ground often contains salts that are then deposited on the wall when the water evaporates.
These salts can cause the paint to bubble and a white fluffy deposit to be left on the surface. There are two main types of salt - sulphates which result in crusty white patches and invisible hygroscopic salts known as nitrates and chlorides. The hygroscopic salts continue to draw moisture and therefore must be treated.
Salts debonding the paint work - if you look at the top of the bubble you will see the white fluffy salt deposit. Rising damp in internal walls is caused by the same movement of ground water up through the brickwork by capillary action.
Rising damp can affect both internal and external walls. When looking for evidence of rising damp on external walls, again you should keep an eye out for tide marks. You may also see some of the mortar crumbling between the bricks or stonework and salt deposits too.
Rising damp is a relatively rare form of damp and treatment will only work if it is correctly diagnosed. It is therefore vitally important to get a professional diagnosis from a qualified surveyor — this will involve a rising damp survey of your home including analysis of the salts. It can be hard to distinguish rising damp from other forms of damp like condensation or penetrating damp. Having said that, the following are some of the more common signs of rising damp that you can look out for:.
Rising damp is often characterised by the tide marks on your wall above the skirting as well as powdery white salt deposits. It can cause plaster to bubble and wallpaper to peel away. The following rising damp images give you an idea of the visual appearance of the signs of rising damp:. Rising damp can be a serious problem, as if left untreated it can lead to structural issues.
The damage it can cause to your plaster, flooring and decorative finishes as well as the smell also makes it very unpleasant to live with. As with most forms of damp, rising damp is not good for your health, making some respiratory conditions much worse. It can also result in increased heat loss, leading to higher energy bills. If you are in the process of buying a house and a survey carried out by a RICS-approved surveyor suggests that you may have an issue with rising damp, you should investigate further.
We would recommend getting a professional damp company to carry out a rising damp survey before completing on the property. You will want to get a qualified surveyor ideally with industry-recognised professional qualifications. If your property was built after the s, you would expect to find some form of DPC whether it be bitumen or slate. It is rare that this will have deteriorated unless there has been some subsidence which is a very serious issue in itself.
Another potential reason the DPC has failed is that it has been bridged, usually by debris or insulation in the cavity wall that exists below the DPC level. The ground levels outside could have also risen above the DPC level. If you suspect that your rental property has a problem with rising damp notify your landlord or letting agent immediately. The most effective and economical way to treat rising damp is with a damp proofing injection cream.
You can choose between complete kits or individual cartridges of cream from leading brands such as Kiesol C and Aida. The cream is injected or hand-pumped into specially-positioned holes in the mortar course. Once inserted, the damp proofing cream reverts to a liquid. This allows it to penetrate the bricks and achieve complete absorption. As it cures, it creates a powerful water-repellent barrier and a new chemical DPC that stops water from rising up the wall.
For full instructions on how to treat rising damp with damp proofing cream read our guide to injecting damp proof courses. Alternatively, you can install a new damp proof membrane to act as a damp proof course. This is a much bigger and more complicated process that involves taking out each brick along the failed mortar course and installing a new physical damp proof membrane.
When you see evidence of rising damp on internal walls, you need to remove any wallpaper and plaster back to the bricks or substrate. You will also need to do this on the external wall of the property. Treating rising damp on internal walls is all about carrying out the injection process as outlined above and then getting in a position to make good and redecorate internally.
The quickest way to do this is with a damp proof membrane. Chemical injections are highly effective at treating rising damp if installed correctly. The formulations have improved over the years and are now proven to provide long-lasting protection.
