Can I Damp Proof My Home Myself?

Dampness in our homes can be a nuisance, causing unsightly stains, damage but also potential health problems. When faced with damp issues, homeowners often find themselves wondering if they can tackle the problem on their own or if professional help is needed. This blog aims to explore the concept of damp proofing and delve into the feasibility of a do-it-yourself (DIY) approach to damp proofing.

What is Damp Proofing?

Damp proofing refers to the steps taken to prevent or control the entry of moisture into buildings. It is important to address damp problems quickly, as they can lead to structural damage, mould growth, and health issues such as allergies, asthma and other respiratory problems.

What Factors Influence The Feasibility of DIY Damp Proofing?

The severity of the Problem

The scale of the damp issue is an important factor to take into consideration when deciding to undertake any damp proofing yourself. Minimal surface-level dampness or condensation issues are sometimes manageable with DIY methods. However, structural issues or persistent water ingress will require professional assistance.

Skill and Knowledge

Damp proofing involves specialist techniques, such as installing damp-proof membranes, repairing external drainage systems and applying sealant. Assess your knowledge and ability to determine if you possess the expertise to effectively damp-proof your home. It is crucial to remember that flawed damp proofing can make the problem worse or lead to unnecessary costly future repairs.

Understanding the Cause

Effective damp proofing can only be done with a solid diagnosis of the cause of the dampness. Issues such as condensation can usually be resolved with simple lifestyle changes but other causes may require specialist equipment and knowledge. If the root cause is easily identified and solved then DIY damp proofing is more likely to be possible.

How Do I DIY Damp-proof My Home?

Ventilation – A home should have adequate ventilation to prevent dampness caused by condensation. Ensure that each room is properly ventilated by opening windows and using dehumidifiers or extractor fans. These steps can be effective in combating minor issues with condensation.

Surface Treatments – Water-resistant sealants or paints on internal walls can help reduce moisture absorption and prevent dampness from occurring in your living space. However, if there are structural issues surface treatments alone will not be sufficient to prevent damp reoccuring.

Exterior Maintenance – Regular maintenance and inspections of the outside of your property is crucial for preventing dampness due to leaks or poor drainage. Gutters and downspouts should be clear and debris, cracks in walls should be repaired as well as gaps around windows and doors.

When Do I Need To Seek Professional Help with Damp Proofing?

Some minor damp issues can be resolved and prevented through DIY methods. However, there are lots of situations when professional assistance is highly recommended.

Structural Dampness – If the dampness is persistent, severe or impacting the structural integrity of your home, it is best to seek advice from a professional damp-proofing specialist. They have access to appropriate equipment and expertise to find the cause of the problem and provide effective solutions.

Insurance and Guarantees – Professional damp proofing services usually come with warranties or guarantees that can provide you with confidence and peace of mind. This can be important when dealing with complex or large damp issues or when looking to sell your property.

Specialist Techniques – Some problems can only be solved with damp proofing techniques, such as tanking basement walls, which require specialist tools, skills and knowledge. We advise hiring professionals with experience to ensure successful damp proofing.


To conclude, some minor damp problems can be solved using DIY methods but it is important to assess the severity of the issue, understand the cause and evaluate your own ability and knowledge. Professional damp proofing specialists have been trained to expertly diagnose and tackle complex damp issues. If you have any doubts, we advise you to consult with a professional to ensure that any issues are effectively resolved to prevent further damage to your home and well-being.
