Mastic sealing around Kentsboro: what changes locally
Kentsboro sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. Kentsboro lies roughly 68 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
For owners and agents with buildings in or around Kentsboro, block-wide mastic programmes deal with frames and external joints of the same age together.

About our mastic sealing in Kentsboro
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. We work on communal kitchens and washrooms, balcony and threshold joints and external wall and movement joints, and the failures we are asked to look at most are draughts at frames across a block and damp patches beside frames. For commercial sealant work in Kentsboro, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For owners with a single building near Kentsboro, we plan to finish in one visit where possible. Send photos of the frames and joints and we’ll give a fixed quote.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What else we do in Kentsboro
Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Kentsboro, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Getting the site ready

- Working within restricted access windows

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Details that help us quote

Questions we are asked in Kentsboro
Do you work for managing agents with blocks near Grateley station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is a smaller place like Kentsboro outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Can people stay in the building while you reseal?
We plan around people living or working in the building. 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?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Can you take on resealing for a block portfolio?
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.
Surface by surface
Commercial and mixed-use buildings
Where retail and residential share a building, so phasing has to suit both. Tell us your site hours and access windows and we’ll plan around them.
Window and door perimeters on blocks
Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
