Roof Painting
Tiled roof | cleaned and coated
Tiles cleaned down, ridges checked and re-bedded where needed, then coated with a specified roof system.
Waterproofing & Damp Proofing
Water rarely enters where you see it. We diagnose the real source, specify the right system and apply it to manufacturer standards, whether the problem is on a roof, a wall, a balcony or a basement.
Problem & approach
Most waterproofing failures are treated at the symptom, not the source. A quick coat over a ceiling stain, a damp wall or a balcony crack hides the problem while water keeps finding its way in. Tiled roofs, flat concrete roofs, parapets, flashings, balconies, basements, retaining walls, bathrooms and planter boxes each fail differently, and each needs a different response.
We start with a proper diagnosis, then prepare the substrate thoroughly before any product is applied. As an approved applicator of Rubber Sealant® Liquid Rubber, we specify the correct system for the area (roof, wall, balcony, basement or wet room) and apply it to the specification the guarantee depends on.
Where we apply it
One system, Rubber Sealant Liquid Rubber, on every surface. No torch-on, no injection damp courses. The same diagnosis-first approach works anywhere water finds a way in.
What may be included
The exact line items on your quote depend on the site inspection. This is the shape of what a typical project of this type includes.
Products we work with

Our preferred paint on most projects.
We are not a Plascon approved applicator. Plascon is simply the paint we choose to specify for its quality and track record, and we will recommend a different system where a project calls for it.
