Frequently Asked Questions

Damp proofing is a process used in construction and building maintenance to prevent moisture from entering a building. Moisture infiltration can lead to various problems such as mold growth, structural damage, and deterioration of building materials. Damp proofing techniques are employed to prevent these issues.

There are several methods of damp proofing, including:

1. Damp Proof Course (DPC): A damp proof course is a layer of water-resistant material (such as bitumen or plastic) that is installed in the walls of a building near the ground level. It prevents moisture from rising through the walls by capillary action.
2. Damp Proof Membrane (DPM): Similar to DPC, a damp proof membrane is a thick plastic sheet that is used under the concrete floors and sometimes in walls to prevent moisture from seeping into the building.
3. Waterproofing: Waterproofing involves applying a waterproof layer or coating on surfaces like roofs, walls, and basements to prevent water penetration. Waterproofing methods can include the use of waterproof membranes, sealants, and specialized paints.
4. Cavity Wall Construction: In cavity wall construction, an outer and inner wall are built with a gap (cavity) in between. This gap can act as a barrier to moisture, preventing it from reaching the inner wall.
5. Drainage: Proper drainage systems around the foundation of a building can redirect water away from the structure, preventing water accumulation around the foundation.
6. Ventilation: Adequate ventilation is essential to prevent condensation, which can lead to dampness. Properly ventilated spaces allow moisture to escape, reducing the risk of damp problems.

Damp proofing is a crucial aspect of building construction, especially in areas prone to heavy rainfall or high humidity. It ensures the longevity and structural integrity of buildings by protecting them from the damaging effects of moisture.

Damp proofing, if carried out correctly, will last for decades. The materials and chemicals that we use for damp proofing have a life span of at least 50 years. Be warned though! Some damp proofing companies cut corners and do not complete a damp course how it should be. They will offer you a cheap quote and take your money, then run! While you may be tempted with a cheap price, remember, you get what you pay for.

All our damp proof work is guaranteed for 10 years and we know our 3-stage remedial damp course is completed correctly to ensure you will not have further issues. 

This will depend on the size of the area which requires work. Typically most damp remedial work runs into the thousands and can be anything from £1000 to £6000. You have to be very sure when spending this amount of money, that the damp proofing is carried out correctly, the damp proof materials are good quality and the company you use is genuine. Another thing is, is are the damp stains actually rising damp? We go to many properties where the customer has been quoted thousands of pounds for a damp course that they don`t actually require!

You could try, but it`s like anything in life that requires skill, experience, knowledge and practice. Would you be able to fly a plane on your first attempt?

When it comes to damp proofing, use a specialist who can identify the cause of the problem, so it doesn`t turn up again. 

We have lost count of the amount of damp courses that we have done, where there has been an attempt to do a damp course a few years earlier. Do it right the first time. 

There are numerous tell tale signs that your property has damp issues, but identifying the true cause takes a specialist. You may have signs of wall paper coming off the walls. A water tide mark running across the lower part of the wall. Rotten skirting boards. Mould on the walls. A floor that bounces when you walk on it. Salt stains on the walls.These are a few signs of damp problems but they may not be rising damp. It could be water ingress, condensation, or even a leak. Call us today so we can help you find the true problem.

A dehumidifier will  temporarily help to get rid of damp, but the problem will not go away. You have to find out why the damp is there in the first place. 

To use a dehumidifier correctly, you have to seal off the room. Most people who have a dehumidifier, do not know how to use it correctly and the unit will just draw moisture out of the air and be a waste of time and money. 

Whether damp proofing is covered by building insurance depends on several factors, including the cause of the dampness, the type of insurance policy you have, and the specific terms and conditions outlined in your policy.

1. Cause of Dampness: Insurance policies typically cover sudden and accidental damages, such as those caused by storms, floods, or burst pipes. However, gradual issues like dampness due to poor maintenance or wear and tear might not be covered.
2. Type of Insurance Policy: Homeowners' insurance policies and building insurance policies vary in coverage. Some policies might include coverage for certain types of water damage, while others may require additional coverage options for specific situations like flooding. It's essential to carefully review your policy documents to understand what is covered.
3. Policy Terms and Conditions: Even if your policy covers water damage, there might be limitations or conditions. For example, the insurance company might cover the cost of repairing the damage but not the cost of damp proofing if it's considered a preventative measure rather than a response to a covered incident.
4. Preventative Measures: Insurance policies generally focus on repairing or replacing damaged property rather than funding preventive measures. Damp proofing, being a preventative measure, might not be covered unless it's part of a broader repair process due to a covered incident.
