About our mastic sealing in Sissinghurst
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. Most enquiries involve brittle perimeter mastic across a building and estate-wide sealant that is simply worn out, across communal kitchens and washrooms, balcony and threshold joints and communal entrances and stairwells. Facilities teams, main contractors and managing agents in Sissinghurst tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural conversions near places like Sissinghurst 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.
Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or use the quote form and we’ll arrange a return visit.

General trades versus a specialist
Redoing a failed joint normally 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.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Mastic sealing in Sissinghurst: the local picture
Sissinghurst is in the South East, one of the UK’s drier regions. 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. Sissinghurst is about 39 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Property owners at sites such as Hartley Dyke Business Centre (2.6 miles south-west of Sissinghurst) can have mastic renewed between lettings. Schools and community buildings such as Cranbrook School need frame and external mastic kept sound like any building. For agents with blocks near Staplehurst station (4.3 miles north of Sissinghurst), a block-wide mastic programme deals with frames, balconies and entrances in one go.

When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Broken glass or failed sealed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly.
Joints and surfaces we work on

Sissinghurst: questions and answers
Do you work for managing agents with blocks near Staplehurst station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is a smaller place like Sissinghurst outside your area?
Not at all. Sissinghurst is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
How do you handle work on occupied blocks?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Removal of failed or old sealant
- Whether the work must be split into stages
- The site’s rules and procedures
- Location, for remote and island sites
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
What to include in your enquiry
We can often quote from photographs and a few details. It helps to include:
- The postcode of the building
- The type of building and who uses it
- Clear photos of the problem areas
- Drawings or a marked-up plan, if available
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Looking after the joints
For the best life from the joints:
- Protect low-level joints in entrances
- Check the asbestos register before any old mastic is disturbed
- Share your contractor requirements early
- Track which buildings were done and when
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.
