Steve are Graeme are experts, efficient, professional and leave their work site very clean. Their sealing products and colour matching are high quality. Steve came and resealed 3 of our bathrooms from floor to ceiling. The quality of his work was exceptional and because of this we asked him to seal our massive 65sqm balcony which was damaging the cedar lining underneath. Thanks so much Steve and Graeme. Your workmanship is excellent and has prevented costly cedar lining restoration costs.

From initial contact, the quote and service was professional and friendly. The quote was very good value compared to the market. Steve did a terrific job on our bathroom, looking like new. And also did repair work on our balcony. Again a great result. Highly recommended.

Stephen solved a number of problems with our balcony and showers. We cannot recommend him too highly. He was punctual, worked without stopping and left everything spick and span.
