There are several common signs of underlying damp or moisture problems, including:
Call our expert team today and we will correctly identify the cause of the damp problem and recommend the appropriate treatment.
Have you discovered black mould on your walls? This is a very common problem, and in our experience is usually the caused by high condensation levels and poor ventilation within the property. Black mould can spread rapidly and is a concerning health risk especially if suffering from Asthma and or respiratory problems.
Our expert team of specialists can assess the situation and combine the mould treatments with an upgrade of ventilation, this being extra air vents fitted and /or fitting a Positive Input Ventilation unit (PIV). PIV units can be installed in the loft or on the wall and help to control the humidity as well as purifying the air.
Call our professional surveyors out to identify the extent of the problem. Our mould control treatment not only eradicates the affected area but also provides a protective coating.
Why can condensation be considered a damp problem? The major difference between condensation and other forms of dampness is that you have the ability to reduce or solve the problem through changing behaviour in the home, for example drying the washing outside, keeping tumble dryers vented to the outside, opening windows regularly to allow for better ventilation.
However sometimes additional steps and measures are required, contact one of our damp experts today to assess the property and carry out a survey. PIV units – we can supply and install a loft mounted or wall mounted Positive input ventilation unit as an option to control humidity and purify the air thus helping to eliminate any condensation issues.
Our experts can inspect and diagnose a wide range of timber problems such as woodworm infestations and wet/dry rot, and carry out treatments as soon as possible. We can administer water-based treatments to kill off woodworm and and fungicide to stop rot. We will remove any visible fungal growth and replace the timber if necessary. It is important to treat timber issues as soon as possible to prevent undermining of the structural strength of the timber.
If you suspect you have woodworm or wet/dry then call us today. Signs of woodworm include small round holes in the woodwork, and a fine, powdery dust around the holes. Rot is identifiable by a musty, mushroom smell, white fungal growth with yellow and lilac tinges, and cracking appearing within the wood.
Your home requires a lot of upkeep and one of the major issues than can occur is water damage. The good news is that there are things that can be done in an attempt to prevent this and our waterproofing service is one of the best things you could opt for. Most cellars are set either partially or completely within the ground which means they tend to suffer from problems with damp.
Whilst your cellar may never have experienced flooding, with the area being underground there is a high possibility that this could occur in the future. There are two types available for damp proofing cellars Cementitious Waterproofing and cavity drainage systems-water management. We have the knowledge and skills regarding the various methods meaning that we can always ensure that we take the best approach to the job in hand.
Why do buildings need underpinning? If you think or you’ve been told that your home needs underpinning it’s likely because the building is sinking into the ground: a form of subsidence. Subsidence is more likely to affect semis and detached but in truth any home can be affected. Call our expert team today to discuss any of these concerns .
Faulty wall ties can cause horizontal cracks and bulges to appear in your brickwork and even plaster cracking . Cavity wall tie failure is either down to an issue with the construction and installation of the ties or due to the corrosion over time. Cavity wall ties can fail because of a construction defect such as the original cavity wall ties being incorrectly spaced, incorrectly fixed or too short.
Whatever the cause of wall tie failure it is important that the problem is resolved quickly and correctly to avoid serious structural damage and prevent danger of collapse .
