Mastic sealing in Navestock Heath
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. If you have cracked, hardened mastic round windows on a block and complaints coming in block by block, we can help, whatever the surface. Looking for mastic applicators who cover Navestock Heath? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
For buildings around smaller places like Navestock Heath, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered
Can one quote cover a number of our buildings near Navestock Heath?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Is Navestock Heath too far out for you?
Not at all. Navestock Heath is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you work for managing agents and housing associations?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you send RAMS and CSCS details before starting?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Reduce knocks to communal area joints
- Share your contractor requirements early
- Start inspections with the most exposed faces
- Avoid piecemeal callouts where you can
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Signs you need mastic sealing in Navestock Heath
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
Most enquiries start with one or more of the following:
- Draughts at frames across a block
- Patchy repairs in mismatched sealant
- Damp patches beside frames
- Communal area joints that look neglected
Historic properties like Hill Hall (3.2 miles north-west of Navestock Heath) show the age of some local stock, where frame mastic must suit soft brick or stone.
