Timber preservation

Timber preservation is the method of preventing and tackling the effects of:

Dry Rot

The presence of damp in timber can lead to an outbreak of Dry Rot; an aggressive wood-consuming fungus which can cause irreparable damage to the timber.


Damp timber presents a source of water and food for wood-boring insects, an ideal environment for a colony. These insects devour the timber which they infest, causing it to weaken and break.

Wet Rot

Timber affected by damp can permit Wet Rot fungus to grow. Over time, Wet Rot causes timber to weakened as more and more of it is consumed by the fungus.

Where fungal decay or infestation occurs in timber, this will invariably lead to those timbers becoming weak, damaged and dangerous.  As such, when these problems are discovered, you should seek the help of a trained expert as soon as possible.

How we can help

Timber decay and infestation are complex problems and require an experienced hand to diagnose them and assess the extent of the damage that has occurred.  At Allerton Damp Proofing, our expert CSRT surveyors are leaders in the field of the diagnosis of timber decay and infestation.  As part of our service, our surveyors will recommend:

  1. The appropriate treatment required to eradicate the decay or infestation;
  2. The amount of repairs required (if any) to make the structure safe;
  3. The extent of replacement timbers that will be needed; and
  4. The works required to fix the source of water which has led to the decay or infestation.

Once our surveyor has prepared their report, our PCAQT Certified Technicians will carry out the repair works to the highest possible standard.

How we work

With more than 33 years experience in the trade, there aren’t any problems out there which we can’t diagnose or put right.  Having the right knowledge is essential, but the way in which we share our expertise with our customers in what really sets us apart from our competitors.

Firstly, unlike our competitors, our CSRT Surveyors do not work on commission and they are only rewarded for good customer service; as such, you can guarantee that when we inspect your home, we provide our analysis as an expert, not as a salesman.

Secondly, we ensure that we always have the capacity to react to our customer’s problems quickly. Where timber decay and infestation are detected, reacting quickly is essential as these problems can pose a risk to your safety. If you’ve found any evidence which you suspect to be timber decay or infestation, don’t hesitate, contact us today for a fast and effective remedy.

Timber preservation and damp proofing

You might wonder why damp proofing generally goes hand-in-hand with timber preservation. Well, the answer is simple; both problems are often found simultaneously affecting a home. This is no coincidence as when damp affects timber, the timber presents a valuable source of food and water for wood rotting fungi and woodworm. So, the the method of preventing timber decay and infestation always starts with protecting the timber from damp.

Our team of experts specialise in the strategy of timber preservation. Our Surveyors identify the extent of any existing problems and determine to what extent any affected timber is damaged beyond repair. Once this has been established, our team will set down a strategy to remedy the problem. We will preserve as much of the original timber as possible, ensuring that costs are kept to a minimum, and replace what is needed with new specially treated timber products which are resistant to decay and infestation. Any original timbers which remain will be treated with specialist fungicide and insecticide to ensure a lasting resolution.


“Are chemicals used in the timber preservation process?”

The process of eliminating woodworm of wood-rotting fungi can necessitate the use of specialist pesticides or fungicides. However, we only used products which meet with the required industry standards and are approved for use in homes. Additionally, when we use any such chemicals, we will advise you on the suitable precautions to take to prevent anyone in your home being injured during the treatment process.

“I’ve found decay and an infestation, can I ignore it?”

It is never advisable to ignore signs of timber decay or infestation. The reason for this is that, with the passage of time, fungi spreads, insects multiply and more timber is consumed, causing its eventual collapse.

If timber decay or infestation is left untreated, it almost inevitably leads to greater repairs and more cost to the homeowner.

“My floor is rotting, will it all need to be replaced?”

In short, not necessarily. If the timber decay is affecting only a small part of the floor, the need for replacement timber might be small. In many cases, it is entirely possible to treat affected timber without replacing it, though this often depends on how soon a problem is detected and how quickly it is caught. In any case, our Surveyors will advise you to what extent any timber needs to be replaced before going ahead with any works.

Please note that, as a provider of essential services, we are still open for business, with some restrictions. As a new or existing customer, you can continue to call us to discuss new or existing projects.

Please note that we have had to restrict our work in occupied homes considerably, due to the risk that this might pose to our customers and workforce. However, our work in empty homes and properties continues largely as normal.

If you would like to speak to a member of our team about anything to do with our work during the COVID-19 crisis, please contact us, as normal, using any of the contact details on this site.
