Right from the very start Geoff exceeded my expectations It is very hard sometimes to try and find the right person to carry out any type of work. Sometimes you are a bit dubious about the right person or company to do a job for you. There are not many occasions when you come across someone as lovely and knowledgeable as Geoff. For anyone looking for someone you can trust for your damp work then I cannot recommend Geoff highly enough. Geoff took his time to go through exactly what was needed unlike another local company who couldn’t wait to tell me that I required major work doing on my house! The money I paid for my damp survey was worth every penny and I’m a believer sometimes you have to pay for the expertise and knowledge of someone who has many years experience to come and inspect your property. You also know when you meet someone if they are experienced in their role and not just a ‘ so call salesman ‘ who just wants to stick their machine next to your walls and then come ba...

We highly recommend Preservit. Geoff came and surveyed our rising damp issue (no charge for this) and clearly explained what was needed. He kept in regular touch regarding times and dates and always arrived as arranged. The work was carried out in as unobtrusive a way as possible with care and attention to tidiness and minimising of mess. We are very pleased with the quality of the work and highly recommend you give Geoff a call.

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.
