Mastic sealing in Finstock
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on external wall and movement joints, balcony and threshold joints and communal entrances and stairwells, and what we are called in for most is damaged joints in communal entrances and corridors and damp patches beside frames. Most enquiries from Finstock start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
For buildings around smaller places like Finstock, we group work so one trip covers it. Send photos of the frames and joints and we will give a fixed quote.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Maintenance after handover
A few simple habits keep the new joints working:
- Prioritise elevations facing the weather
- Mention RAMS, insurance or CSCS requirements up front
- Track which buildings were done and when
- Include mastic in your cyclical inspections
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Your questions answered
Will you take on a block within reach of Finstock station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Is Finstock off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
How long will the new sealant last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
How do you handle work on occupied blocks?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Blocks and managed buildings in Finstock
Central London is about 64 miles from Finstock. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
For a school such as Finstock Church of England Primary School, perimeter mastic on windows and doors is a holiday job. For owners of several units at places like Manor Barns Business Park, less than half a mile to the north of Finstock, one programme can deal with frame and external mastic across the lot.

What we are called out for in Finstock
The edges of the material itself sometimes break away for example where render or brick edges crumble. We will tell you if the joint edges need repairing before resealing.

Questions to ask before you book
- How long is the guarantee, and what does it include?
- Their public liability cover
- Do they follow the manufacturer’s priming guidance?
- How they’ll work around occupants
What sets the cost
To price the job, we consider:
- How much existing material needs removing
- Backing rod, priming and other preparation
- Travel to remote or island sites
- Which sealant the job calls for
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- The asbestos register, for older buildings
- How the joints are reached, and at what height
- Where the site is, with the postcode
- The product your specification calls for
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Why act early in Finstock
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. Converted and older buildings near places like Finstock tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
