Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Mastic sealing for commercial buildings in Brompton
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. If you have estate-wide sealant that is simply worn out and a mix of products and colours from past repairs, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Brompton is the same: the right product in a properly prepared joint.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For a block or estate, it helps to know where we can park and stage materials.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.
Tenement and older buildings
Stone needs a neutral-cure product, so we pick a grade that won’t mark it.

Do you do block-wide mastic programmes?

When it isn’t the sealant

- Substrate edges that need repairing first
- Broken glass or failed sealed units
