Sovereign Chemicals, market leaders in chemical damp proof coursing, façade treatment and remedial timber treatment


This reputation has been gained for the quality of its products and also for the support and care offered under the Sovereign Protection Scheme Guarantee. Since 1976 over half a million satisfied property owners are testimony to the effectiveness of the Scheme.


Flexibility is available with the choice of 10, 20 or 30 year Protection Scheme Guarantees for timber and damp proof courses and the introduction of a 10 year Guarantee for façade treatment.


Sovereign Protection Scheme Guarantees are offered by remedial contractors who have been vetted by Sovereign. Only when we are satisfied that they are capable of carrying out work to a consistently high standard do we allow contractors to apply to become Sovereign Approved Contractors. Regular site visits ensure that standards of workmanship and customer care are maintained.
