Mastic sealing in Borden
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Mastic sealing in Borden, done properly
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on balcony and threshold joints, communal kitchens and washrooms and window and door perimeters on blocks, and the failures we are asked to look at most are communal area joints that look neglected and old repairs sealed over failed mastic. For commercial sealant work in Borden, you deal with one contact from quote to sign-off, whether it’s one building or several.
For buildings around smaller places like Borden, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Our 12-month guarantee is about workmanship, not 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 we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Misted or failed double-glazed units
- Failed window or door frames, which need a window contractor
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer.
Joints and surfaces we work on
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Balcony and threshold joints
- Window and door perimeters on blocks
- External wall and movement joints
Do you need mastic sealing in Borden?
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Most enquiries start with one or more of the following:
- No planned programme for sealant
- Cracked, hardened mastic round windows on a block
- Worn sealant at communal door frames
- Old repairs sealed over failed mastic
If you look after a block within reach of Sittingbourne station, 1.4 miles to the north-east of Borden, frame and balcony mastic can be renewed on one programme.
Before you book anyone
- Will CSCS-carded applicators be on site?
- Their pre-qualification and accreditations
- Whether primer will be used where the manufacturer specifies it
- Which product they’ll use, and why it suits the joint
Common questions from Borden clients
Will you take on a block within reach of Sittingbourne station?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Borden too small for you to travel to?
Not at all. Borden is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
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.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
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. Borden can form part of a wider programme across Kent.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
Block-wide mastic in Borden
Borden lies roughly 36 miles out from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Rainfall across the South East, Borden included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
If you manage student housing near a university such as Canterbury Christ Church University (4.7 miles south of Borden), the summer turnaround is the time for mastic. For a school such as Borden Church of England Primary School, perimeter mastic on windows and doors is a holiday job.
