We provide surveying and contracting services for the following:

Rising damp
Rising damp is the occurrence when groundwater and surface water gets into the foundation of a property and by capillary action groundwater up through floor slabs external and internal walls.

There can be several reasons for this happening and in most cases this is due to an existing damp proof course, (DPC), becoming defective. Sometimes, raised ground levels such as flower beds or blocked cavities allow for bridging to take place permitting damp to 'bridge' from the outer brick face to the inner.

There is a British Standard for the effective diagnosis and treatment of rising damp; BS6576. This is the code of practice our qualified surveyor works too and our methods or remedial works conform to.

Condensation damp
Condensation damp is the greatest cause for damp in UK properties. In nearly two-thirds of damp related issues, the cause can be identified as condensation damp.

The problem of this kind of damp is becoming more commonplace as building materials and renovation methods allow us to create more airtight and energy efficient houses and flats. The downside is the subsequent lack of natural ventilation allowing a property to air.

Consequently, the internal humidity levels rise to the point they reach what is called 'dew point'. The temperature at which vapour content turns to moisture on cold surfaces which if happens consistently leads to black mould growth.
The historic and commonplace answer to remediate condensation was and still is, to introduce more air bricks and through-the-wall air vents. This is called background ventilation or passive ventilation. This type of ventilation has its place and can be very effective but it is also chosen as the cheapest method to resolve humidity and more often than not, it falls short and the problem soon returns.

The key is to firstly ensure there are efficient extract fans in bathrooms, kitchens and utility rooms of the correct size and location
Thereafter, the installation of additional mechanical ventilation to ensure an automatic and regular air change to the affected rooms or whole property which maintain humidity levels below the level at which condensation damp and black mould thrives.

This can be achieved with Positive Input Ventilation systems, (PIV), or Heat Recovery Ventilation systems, (MVHR).
As to which type of ventilation system is installed or even a combination, is determined by the size and type of the property and the volume of air to be moved, the nature of building construction and the extent of the condensation damp issue at hand.

Our surveyor and team have successfully remediated numerous flats and houses making them permanently free from this depressing problem.

Penetrating Damp
Penetrating damp or as other call, Lateral damp, is the ingress of damp through the walls in the main brought about by faulty rain goods and guttering but also structural defect.

Once the cause has been identified and remedied, the affected areas will start to dry down naturally. The application of externally applied treatments assist with the drying down process and help to prevent the problem returning provided that the original cause has been adequately rectified.

Stubbington Dampsolve are experts in waterproofing and tanking methods. From dealing with soil retaining walls or rooms and properties partially below ground level, we can provide a suitable solution to cure any damp issue.

Basement and Cellar Waterproofing
If you have an existing cellar or basement you would like to use for dry storage or upgrade to habitable use such as an office, games room, study or even a bedroom we can take you through the design process which if necessary, includes architects drawings, structural engineers report, planning approval and building control application to the complete installation and fit out process.

Alternatively, if you have an appointed builder of your own, we are happy to work with them on the waterproofing stage.

Woodworm Treatments
If you have taken on a new property or carrying out renovation works to your existing property and have identified rotting timbers or signs of woodworm, we can advise on a suitable remedial strategy.

In many cases the solution is straightforward. The key is correct identification of the issue in order the correct treatments are applied.

Wall Tie Replacement
More often than not, wall tie replacements come to light following a Surveyor's visit for a property purchase. In most cases, it refers to wall tie corrosion which is more common place in properties situated close to coastal areas and becoming affected by airborne salts.

Other situations are connected to structural defect such as a bowing wall. This in most cases will be an insurance repair and your first port of call is to your insurers. We will be happy to advise you.

Moss, Algae and Lichen Removal
If your property has developed unsightly areas of algae and lichen growth or moss growing on roofs, gutters, walls, etc this can potentially damaging to the structure and rain goods and in the case of algae forming on paviers, can be dangerous for footing.

Stubbington Dampsolve have a range of harmless chemical treatments that after application will have your paviers, guttering, roof tiles and even decking, looking spick and span. The treatments are long lasting and water based so after they have been applied, are not harmful to adults, children or pets.

Epoxy Liquid Floor Membranes
If you are looking to damp proof a concrete floor slab or provide a durable floor coating to a garage or workshop area, we can apply a damp proof epoxy liquid floor coating which will provide you with excellent results.

Epoxy floor coatings can take light vehicle traffic, fork lift traffic and heavy footfall. It also provides a damp proofing barrier to water penetration from the ground. We can incorporate a non-slip finish as required.

Epoxy liquid floor coatings are available in a number of colours including clear if a natural stone or brick feature was wanted to be retained.

Case Studies

The Client wanted to damp proof for dry storage

We were engaged to damp proof a bedroom to a detached bungalow suffering from structural damp and condensation damp.

Rising damp correctly diagnosed due to failure of the DPC.

We were invited to remediate a damp issue to a solid construction gable end wall suffering from condensation damp internally which is partially below the external ground level.

We were invited to carry out a survey to a property that we subsequently identified was suffering from Dry Rot and Wet Rot.

Terraced house with a two storey bay without any rainwater guttering. The effect was for surface water run-off to splash on the ground and spatter back up over the damp proof course.

A pillar was suffering from aggressive salts to which we applied a salt neutraliser and within hours you can see the salt beginning to strip back. Our work can be compared before and after from these images.
