Core Conservation Reviews

1897 building

I can also honestly vouch that the system provided by Core Conversation is genuine and does work as stated.

We had a system fitted in our home which was built in 1897 and had a rising damp problem. Upon a survey visit exactly 6 months after installation the house was almost 100% dry, 12 months after installation a second survey was carried out and showed the issue had been completely remediated. We did have both gable ends of the house repointed with lime based mortar and have not had any issues since.

We are 100% satisfied with the magnetic DPC system and would recommend it to anyone.


When we first heard of the product, we did think that it was almost too good to be true, then when Val explained it to us we knew it was for us! In reality, it is a good bit of kit and we shall not stop recommending it!

We have a Grade II listed Tudor cottage one of our resident black labs sitting on the wall! The DPC issue is particularly interesting from our point of view. We were plagued with damp here and every 25 years had to have walls hacked out etc., it was very messy and boring. Then we found Core over 2 years ago (from the LPOC) and we do not have damp anymore, just a small gadget under the stairs, that works with microwaves which (miraculously) send the damp away (no kidding)! We don’t have to have walls raked out either! The cost relates to the m2 of the property.


We installed magnetic DPC systems in two properties about three years ago and they have done their job well.

Both properties were extremely challenging as they were built long before damp courses were common practice. The system is the least invasive and most practical and the least expensive means of tackling rising damp problems in older properties.

Val and his team have been a delight to work with. They have returned regularly to monitor the effectiveness of the system which has proved every claim they made when they sold the system.

This level of commitment and sense of continuing responsibility for their work is rare these days.

They have also been very helpful in giving advice well beyond the scope of their product as our 17th Century fisherman’s cottage is in a flood zone and occasionally is subject to tidal flooding on its exterior walls. Centuries of saline rising damp has left salt deposits deep within the fabric of 2 ft thick walls. These deposits are being drawn out of the now dry walls during the cycle of atmospheric condensation and crystallization. It is a slow process, but their advice has been invaluable.

Core Conservation's expertise has been excellent and as a customer one gets the sense that whatever your problem might be it is a problem they share.


We came into contact with Core Conservation several years ago at a listed property owners convention in Harrogate.

We had issues with damp in our house and cellar which was causing us concern.

We had the usual damp course work done but the problem remained that the house seemed damp still.

We were really impressed with the magnetic DPC system and the knowledge of the staff.

After discussions with Core Conservation, the team visited the house completed an in-depth survey and informed us all the way about the short and long term benefits that the magnetic DPC system could provide.

We have had positive results with the system and there has been a significant improvement to the damp in the house. The company have been consistent in providing us with surveys and the results within an agreed time frame. They are a very professional team and have provided us with a high quality service, written reports backed up with statistical information from the installed equipment and are a highly professional company that I would have no hesitation recommending.


My house has originally been an agricultural farm house, a potting shed built of sandstone, without a proper damp proof course. The stonework on the outside our house always has shown signs of damp and a bit of spalling and flaking. After 6 months there is a significant improvement, damp is reducing. Visually there has been a difference but more importantly your measurements have also indicated there is a definite difference, so your system must be working. It was still surprising and rewarding to see the results that I have now seen 6 months on.

Potting Shed

Old House by the Canal

The house has been built in 1804 and it is situated very close to a canal. It used to be a shop and I converted it into a house. I have been living in it for 20 years and the basement was always damp.

I heard about your dehydration system from my builder who rented a garage next to mine. The system has been installed 6 months ago in June. The dampness in the ground is now gone, the room is operating normally. Where it previously took 3 hours to heat up the room now the room is operational in half hour, just like the rest of the house. It's a much pleasanter environment down there than before. I am very pleased with the results and if any of my friends would have similar problems I certainly wouldn't have any hesitation to recommend you.

Scottish Castle

I am a physician, general medical practice. We own a medieval castle which was finished in 1577. The walls are red sandstone held together by lime mortar with rubble in-between, harled on the outside and lime-washed on the inside. The castle is built without any basements, the building really just stands on the ground and it has no damp course.

There is always rising damp creeping up the building, especially on the ground floor where it was rusting the sockets. We wanted to tackle the problem so we spoke to Core Conservation. They came out last year, did a bunch of measurements, fitted their damp system and one year later the stone is drying out, the cement is drying out; they are about 50% drier than last year. It is much better than it was.

Initially we had quite a lot of mildew and keeping the building warm did not help with that. Two things helped with the mildew: 1. the damp proofing system by reducing the moisture in the lower part of the building; 2. better airflow through the building.

Working with your staff was very easy and straightforward, very agreeable people, lots of integrity. The work was very professional, tidy, no mess left at all. I would have no hesitation recommending you to anybody.

Old Cottage

As an architect I worked on both old and new buildings. I live in a stone-built farmer Border cottage built around 1910. Under the staircase there was a lot of fungal smell, which also permeated the clothing. This was particularly noticeable when I had a visitor. When they left home and opened their suitcase they had a very strong fungal smell coming from their clothing. You could feel this smell around the central wall, which is a solid stone wall with the staircase around it.

I came across your dehydration solution when you have been doing some work at one of my neighbours. I had your system fitted a year ago. After about 3 - 4 months I began to notice a difference: I got the feeling that the air is lighter somehow, not so heavy. The smell seems to be considerably reduced. When now I put my head under the staircase I don't have that strong, almost eye-watering smell. On my last trip to Sweden when I opened my suitcase I did not have the smell either.

Bed & Breakfast

I run a B&B built in 1889 and had damp issues in the basement. I kept my linen and towels there and despite several washes I was getting that horrible musty smell. Every time I walked down the stairs into the basement I could smell that musty smell, so I had to do something about it.

I contacted Core Conservation through the internet, they came out and investigated the problem. They took samples out of the walls, measured their moisture content and confirmed that there was rising damp. Another company recommended me tanking, which would have only solved some of the problem instead of the whole issue, so I went with Core Conservation as it was the right thing to do.

Once the dehydration system was fitted, about a month or so later, I noticed that the smell has reduced, got less and less until I could not smell it anymore. And I thought: "Oh, I got so used to it that I can't smell it anymore." But my son visited me, funnily enough, this weekend and even he noticed that the smell was gone. He left a lot of his stuff in the basement and he used to moan about the musty smell and he had to throw some of his clothes out. This time, however, he didn't say any of that.

Initially the walls have been cold and damp, the samples taken from the walls were visibly wet. Now, at the last check the samples were not wet at all. You can also tell when you are in there, that you don't get that damp feeling down there.

Country House

We have two young girls, they are absolutely full of life and the last things we want to do is to encourage any respiratory or health issues.

Lily, age 6, she has a history of chestiness, she has been admitted to hospital for chest infection from a young age. Since the installation of your dehydration system she did not have a flue or a cough. She has been "symptom free", so to speak, for the last year, which is good. Whether that's an indicator, I don't know, but I wanted to mention it. The results speak for themselves.
