We are a family run business of over 30 years. We are experienced in all aspects of the building trade and excel in damp proofing solutions and wood treatments. We are experts in providing damp proofing solutions, tailored to meet your needs.


Our expert surveyors will visit free of charge and provide advice on your damp problems. Before initiating any remedial work it is essential to properly assess:
- is dampness present;
- is the building suitable for a particular treatment;
- is the building being modified and will that affect any treatment.
Our surveyors will take into account all of the factors and will only suggest remedial work if you need them.


We are proud members of the Institute of Master Builders.

Area of Business

We offer damp proofing treatments throughout the north London area and the whole of Hertfordshire, including Watford, Hemel Hempstead and St Albans. We are a company built solely on recommendation and referrals from overly satisfied customers and we are proud to accept new and returning customers - no job is ever too small.

We are experts in all types of damp proofing with a wide experience of problems caused by the effects of damp such as wet and dry rot, timber infestation and all types of damp in the building fabric. In addition, we can provide you with extra accommodation by damp proofing any cellar area.


All initial visits and estimates are free of charge. Full reports are available for a small fee, which is fully refunded if we get the job.
Our prices are competitive and specific to the type and size of the remedial work required.
We use only proprietary branded products from well known suppliers.
