Mastic Sealant Contractors

Bathrooms and kitchen sealant

We will assess the area that needs a sealant application and identify areas where moisture is likely to congregate. From there, we will prepare the surfaces, and ensure they are free from debris.

We will select the correct type of sealant and apply it using specialised techniques and tools, ensuring the finish is perfect, both aesthetically pleasing and preventing water incursion.
