Mastic sealing in Silverhill, done properly
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on communal kitchens and washrooms, shopfronts below residential blocks and balcony and threshold joints, and the usual reasons a site gets in touch are movement joints with sealant missing and damaged joints in communal entrances and corridors. For commercial sealant work in Silverhill, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In a smaller place such as Silverhill, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Start inspections with the most exposed faces
- Protect low-level joints in entrances
- Have the asbestos survey to hand for older buildings
- Keep a record of when each building was resealed
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Silverhill can sit alongside others in a wider programme across East Sussex.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
For owners and agents in Silverhill
The sea is no more than about 2 miles from Silverhill. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first. Silverhill lies roughly 52 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
Site managers at schools like Christ Church CofE Primary and Nursery Academy can fit frame mastic into the summer works. Landlords with units on estates such as York Road Business Centre (to the east of Silverhill) can bring frame, door and external mastic across several units into one programme.

Silverhill: questions and answers
Will you work in a care home in Silverhill without moving residents out?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we will work to them.
Does your area include sites such as York Road Business Centre, near Silverhill?
Yes. Our area takes in Silverhill and its surroundings, with estates and business parks such as York Road Business Centre included. Photos and a short description are enough for a first look.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What do you charge?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Do you work for managing agents and housing associations?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What else we do in Silverhill
Why deal with it now?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Full removal and proper preparation is what lasts. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
