Does DIY Damp Proofing Work?
We at John Newton & Company are often asked whether damp proofing can be done as a DIY damp proofing job. There is a wealth of information available and multiple diy damp proofing products are available online which promise and easy fix.
However, unless you are a damp expert diy damp proofing products can cause a minefield of problems. Where DIY damp proofing can seem like a low cost solution, it can result in a far more expensive strategy than planned, and often the damp problems can return. We are often contacted when a DIY damp proofing job goes wrong, with problems like the following:
- “I used DIY damp proofing cream in my damp basement but the water keeps coming in”
DIY damp proofing is never advisable in cellars or basements. Damp proofing below ground spaces needs the advice of a specialist basement waterproofing contractor, as the job is not just about damp proofing walls, it is about ensuring that a waterproofing system is in place which will divert the water out of the property.
