What happens if it’s left?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and normally fails within a short time. Full removal and proper preparation is what lasts. Converted and older buildings near places like Walberton tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

About our mastic sealing in Walberton
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, with each block quoted and scheduled in turn. We work on balcony and threshold joints, communal entrances and stairwells and shopfronts below residential blocks, and the failures we are asked to look at most are brittle perimeter mastic across a building and open joints in brickwork or panels. Searching for sealant specialists in Walberton? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Owners and agents with buildings around smaller places such as Walberton tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Advice
What we can’t put right
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Leaks from above rather than through a joint
- Misted or failed double-glazed units
Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
What we seal

Planned mastic for Walberton portfolios
There are seven care or nursing homes within about 2 miles of Walberton. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. Walberton is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

How the job changes by surface
Window and door perimeters on blocks
Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.
