Mastic sealing in Sevenoaks Weald, done properly
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. If you are dealing with old repairs sealed over failed mastic and no planned programme for sealant, we can put it right. A single leaking joint is often how a building in Sevenoaks Weald first comes to us: we look at the rest while we are there and tell you what we find.
Rural conversions near places like Sevenoaks Weald often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Doing it in-house
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What affects the price in Sevenoaks Weald
What shapes the price:
- Access and working height
- Induction, permit and paperwork requirements
- Working within restricted access windows
- Location, for remote and island sites
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
To price the job accurately, we need to understand the site. Send us:
- The product your specification calls for
- Drawings or a marked-up plan, if available
- The postcode of the building
- Clear photos of the problem areas
For a fixed quote, speak to us on 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Water coming in from the roof or rainwater goods
- Leaks through the frame itself rather than the perimeter
- Asbestos-containing sealant, which we don’t remove
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think before you book.
What we seal

Blocks and managed buildings in Sevenoaks Weald
Sevenoaks Weald lies roughly 22 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Sevenoaks Weald sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Landlords with units on estates such as Salters Heath Business Centre (to the north-west of Sevenoaks Weald) can bring frame, door and external mastic across several units into one programme. Buildings close to stations like Hildenborough station, 2.3 miles to the south-east of Sevenoaks Weald, are often flats over shops, with frame mastic to keep sound. For a school such as Weald Community Primary School, perimeter mastic on windows and doors is a holiday job.

Advice
Your questions answered
Is Sevenoaks Weald too far out for you?
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 will plan the job to need as few trips as possible.
We manage a building near Hildenborough station. Can you help?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Can you send RAMS and CSCS details before starting?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
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.
Why deal with it now?
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. Older rural buildings around Sevenoaks Weald move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
