Damp Treatments


A damp proof course (DPC) Is a horizontal waterproof barrier found in the external walls of your property, 15cm above ground level. This helps prevent water from getting inside the building and designed to stop moisture from running up walls. It can be made from all sorts of material, such as plastic, lead, rubber, and more. If your property was built within the last century, there’s a good chance it will already have a DPC installed. However, older buildings likely won’t have it, as they were constructed before damp proof courses were widely used. Unfortunately, deterioration with age or movement in the home can cause damage to your DPC, weakening its effectiveness. It can be challenging to know whether your home’s DPC is damaged. You will need to hire reliable London damp proofing companies to perform a survey on your property and advise you on what to do. The only other way of knowing is when the rising damp has already set in and has caused visible damage to your house. Whatever the damp problem may be in your home, Environ will be ready to help. Even issues that can’t be solved with DPC, like basement damp, can be efficiently addressed, as we are also a competent basement waterproofing company. We can provide the best DPC and tanking solutions for your property.


How we treat rising damp? There’s only one rising damp treatment: repairing or installing a damp proof course (DPC). It’s a difficult and costly job, so before we treat your rising damp, we need to make sure we accurately diagnose it. Cowboy damp proofers are notorious for misdiagnosing other types of damp as rising damp so that they can charge a small fortune for DPC repair or installation. At Environ Property Services, we’ll provide you with hard evidence of rising damp before we start digging around beneath your property. If you do need rising damp treatment, the last thing you want is for the damp to come back a few years later. At Environ, our rising damp treatment is built to last, with a 15-to-25-year guarantee that damp won’t return.


How we treat penetrating damp? You can’t just paint over penetrating damp and hope it goes away. If you don’t fix the cause, water will continue to eat away at your property until what could have been a quick fix becomes a serious and expensive structural issue. There are many causes for penetrating damp, from blocked gutters or decayed pointing to broken plumbing and cracked walls. Any route that unwanted water can take into your property can cause penetrating damp. Treating penetrating damp is part detective work, part craftsmanship. Our damp experts will first perform a top-to-bottom survey of your property to identify what’s causing your penetrating damp, then fix it with special damp proofing materials and a flawless finish.

How we treat lateral damp?

Noticing the signs of lateral damp is the first step to getting it fixed. The most important signs to look out for are:

Walls that are cold and wet to the touch

Presence or smell of mould

If you notice any of these symptoms, then there is a good chance that you are experiencing lateral damp in your property, and it is time to call in the damp professionals at Environ Property Services to solve your problem.

How we treat woodworm?

A large number of tiny holes in the woodwork

Flour-like “shavings” from the burrowing (known as frass)

Crumbling edges of wooden boards and joists

Damaged and weak flooring or timbers

If you notice any of these symptoms, then there is a good chance that you are experiencing woodworm in your property, and it is time to call in the professionals at Environ Property Services to solve your problem.

Our friendly and professional coordinators are on hand to set up a convenient time for one of our expert damp surveyors to investigate your property for any signs of damp ingress. Once we have finished the survey, we will provide you with a thorough report. Within this report you will find a full description of what our surveyor observed during the visit, as well as photographic evidence of any problem areas and our recommended remedial works and associated costs. We will be happy to answer any questions you may have and look forward to working with you!


How we treat damp walls?

Are your walls wet to the touch but with no signs of structural damp? Then there’s probably too much moisture in the air, which is settling on the walls as condensation.

Condensation is the most common cause of damp, and luckily, it’s also the easiest and cheapest to fix. Our damp treatment involves installing a PIV unit in your property that will push out the wet, stale air and keep your walls and windows dry and mould-free. We provide the cheapest PIV installation in London and, like all our damp treatments, we include a guarantee that your damp won’t return. And with a running cost of just pennies a day, you can get rid of condensation without breaking the bank.


Whether you’re a family home or a bustling business, our damp surveys.

This survey tells you what’s causing your damp, what we can do to fix it, and how much it would cost. Our damp experts are always happy to show you what they’ve found and explain their solutions.

You’re under no obligation to go any further, but we’re confident that you won’t find a more experienced and friendly team of damp specialists.



Penetrating damp appears on walls and joinery that are prone to prolonged wetting due to poorly maintained rainwater fittings, hairline fractures in pointing, and roof leaks. It can also be caused by overflowing sinks, shower trays, and baths as well as damaged burst pipes and tiles.

You will instantly know that you have penetrating damp if the patches on your walls darken when it rains. Moreover, penetrating damp usually spreads horizontally instead of vertically.

Properly maintaining your home is one of the best ways to prevent damp problems from happening. Here are some tips:

Find leaking pipes and have them fixed. Always look for leaks where water escapes from both internal and external pipes.

Regularly check your roof, walls, and windows for any problems. Any small cracks and holes are basically welcoming excess moisture into your house.

Clear overflowing gutters as the water that they hold can spill down your walls.

Replace old porous bricks or paint them with an exterior silicone water-repellent paint.

Have professionals in waterproofing and damp proofing clear your wall cavities for you. Debris may get stuck into the wall cavity, resulting in water taking a direct route through to the interior walls.


Damp issues can worsen as time goes by, especially if you continue to ignore it. If you see even a small sign of damp, it is important that you immediately use damp proofing London services so that you don’t have to spend a lot of money on serious structural repairs later.

With that said, regularly check for damp issues in your house. Examine the walls, floors, and ceilings as these are the areas where mould and mildew usually form.

One simple trick is to run your hands across the suspected area. If you feel plaster salts – white deposits that were washed out of the bricks and transferred to your plaster – then you most likely have a damp problem.

Wallpapers also show visible signs of mould and mildew by peeling and lifting. If you run your hands over the wallpaper, you may even hear a crunching sound caused by the plaster salts.

But the best and most efficient solution is to call one of our damp specialists and tanking experts, we are well-equipped to quickly identify the main cause of your damp problem and get it treated. Call us today and let us do the hard work!


One of the main causes of moulds and mildew is condensation. You can control the air humidity and keep the surfaces above dew point temperature by using simple methods, such as opening windows for proper ventilation.

If you have non-condenser tumble dryers, then they should also be vented to the outside. Additionally, avoid hanging your clothes to dry indoors.

You can also use dehumidifiers to keep air moisture levels down, though nothing can match the effect of efficient heating and sufficient ventilation.

Lastly, eliminate condensation in chimney flues by using the proper linings. You can also fit sealed flues with ventilation grilles or have them re-opened. If you have a loft in your house, make sure that they are well ventilated and insulated too.

For a damp survey and treatment, call Environ Property Services today! We will be more than happy to go out of our way and solve your property’s damp problems, no matter the extent of the problem!

I chose to use Environ to deal with a damp wall, the whole process from beginning to end has been straightforward, well explained and they've managed to strike a pleasing balance between friendliness and professionalism. Everyone they sent over during the course of the work, as well as their office staff has been, nice helpful and accommodating. I hope not to need to use them again but if I do, I'll do so gladly!

Came round to have a look at work required and actually realised it was all low level work. Explained and showed what was required. They can back about a week later (or thereabouts) to carry out the work which was done very quickly (about an hour if I recall). Because it took less time than was originally thought have not been charged for the materials so was very happy about that.
