Couldn’t ask for more. Geoff came and gave an honest inspection and advised on work required. Where I thought was rising damp he informed me it was due to airflow condensation. I was able to book in a few weeks time which was perfect and kept a us updated all the time. I asked for extra work to be carried out when on-site which he did and every day working areas were left clean and tidy. Even followed up after work completed to check everything was ok. Good customer service, friendly and professional. I have used him in the past and would definitely recommend. Thank you

Geoff was extremely helpful and professional, he came out to look at the issue I had with a damp wall promptly. He diagnosed the problem and within a few days was able to rectify the root cause by injecting a DPC and plastering the wall. The price was very competitive and Geoff was extremely knowledgeable about the problem and how to fix. There was no mess left afterwards and follow up aftercare was really good. Excellent service all round, very friendly and would highly recommend!

Preservit Ltd did a fantastic job damp proofing and replastering at my house. They worked very quickly, removed all the rubbish and tidied up leaving the place as they found it. The quality of work was excellent and I would certainly recommend them highly if you're thinking about having this type of work done.

Have you noticed a small patch of damp on your walls or floor or stained or perished wall plaster? Or maybe you can’t get rid of that damp musty smell in a room? These could be signs of a rising damp problem, and if left untreated, it may lead to mould growth and damage timber structures in your home.
If you are in doubt about the presence of rising dampness within your property, Preservit Ltd. can help. We will perform a thorough rising damp survey to examine your property and identify the source of rising damp and use a suitable damp proofing technique to eradicate the problem for good.

To avoid Wet & Dry Rot regular upkeep and maintenance is essential to ensure the comfort and curb appeal of any home. However, in spite of regular care, fungal infestation may damage the wooden structure of your building. If left untreated, fungal decay may lead to a structural failure of floor and roof timbers.
At Preservit Ltd., we specialise in dry and wet rot treatments. Utilising our deep expertise and moisture meters, we not only locate dry or wet rot, but also eliminate the underlying cause of the outbreak. To restrict the damage, our experts replace defective timber and undertake repairs where necessary to ensure optimal structural strength and stability.

Woodworm can be a major issue to both households and businesses that if left untreated can lead to major structural damage to a building and compromise the safety and wellbeing of its occupants.At Preservit Ltd., we offer targeted woodworm treatment services to eradicate any kind of infestation in a cost-effective manner.

Have you noticed patchy black mould appearing on an internal wall? Or a watermark has suddenly appeared on the masonry? Patchy black mould, watermarks, damp musty smell, and damage to wall plaster roofing and timber are all signs of a penetrating damp problem.
Let Preservit Ltd. conduct a damp proofing survey and help you determine what might be saturating your walls with water.Depending on the underlying cause and the extent of damage, we will then employ a suitable damp proofing treatment to prevent future moisture from penetrating into your property.

Condensation is the most common cause of damp problems in both homes and offices. It is caused by air condensing on internal walls, particularly in rooms with a lot of moisture, such as bathrooms and kitchens.
If you are noticing damp in your home or office, don’t worry. Preservit can help you identify the cause of condensation and take necessary measures to manage and prevent condensation from damaging the aesthetics and comfort of your home.
