Site staff or a sealant specialist?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
About our mastic sealing in Sellindge
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 failed external movement joints and leaks at window and door perimeters, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Sellindge, preparation and product choice get the time they need.
For buildings around smaller places like Sellindge, we group work so one trip covers it. Photos of each elevation help us quote accurately.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Substrate edges that need repairing first
- Failed window or door frames, which need a window contractor
- Leaks from above rather than through a joint
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.

Mastic sealing around Sellindge: how the place shapes the job
Sellindge sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Sellindge is about 55 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Site managers at schools like Sellindge Primary School can fit frame mastic into the summer works. Older community buildings, Church of St Mary among them, often have frames of mixed ages whose mastic varies. For owners of several units at places like Evegate Business Park, which lies west of Sellindge, one programme can deal with frame and external mastic across the lot.
Sellindge is about 4 miles north-west of Hythe, in Kent. Anywhere in TN25, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Kent, 931 places are covered, Sellindge among them. We also cover Brighton, around 53 miles from Sellindge.

Advice
Maintenance after handover
To get the most from the new sealant:
- Mention RAMS, insurance or CSCS requirements up front
- Start inspections with the most exposed faces
- Track which buildings were done and when
- Keep bins and bikes away from communal door frames
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.
Sellindge: questions and answers
Can you quote for a block close to Westenhanger station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Is Sellindge too small for you to travel to?
No. Places such as Sellindge are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Surface by surface
Tenement and older buildings
Stone needs a neutral-cure product, so we pick a grade that won’t mark it.
Planned maintenance
We can work into your cyclical maintenance plan, building by building.
Why act early in Sellindge
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. One visit to deal with every failing joint makes more sense than several trips to a place like Sellindge. Send photographs of each area and we’ll quote for the lot.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
