When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Leaks through the frame itself rather than the perimeter
- Masonry that has broken away beside the joint
- Glazing that needs replacing
If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.

How we handle mastic sealing in East Hill
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in East Hill carry our 12-month guarantee. We work on communal kitchens and washrooms, shopfronts below residential blocks and window and door perimeters on blocks, and what we’re called in for most is mastic failing across several blocks on an estate and cracked, hardened mastic round windows on a block. One point of contact handles commercial sealant work in East Hill from the first photographs to the final walk-round, whether it’s one building or several.
Around smaller places like East Hill, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Plan resealing building by building rather than complaint by complaint
- Include mastic in your cyclical inspections
- Ask residents or tenants to report leaks and draughts early
- Share the asbestos register when you send details
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Mastic sealing in East Hill: the local picture
The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building typically need attention first. East Hill lies roughly 18 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations.
Trustees of buildings like Church of Saint Mary the Virgin can bring frame and external mastic into a planned maintenance list. Older buildings near East Hill, from historic houses such as Lullingstone Castle (to the north-west of East Hill) to more modest stock, need compatible products when frames are resealed.
East Hill is about 5 miles north-east of Sevenoaks, in Kent. We cover commercial sites throughout East Hill, for single jobs and planned programmes alike. 931 places across Kent fall within our area, East Hill among them. Sites around London have their own page, roughly 18 miles from East Hill.

Diagnose, treat, sign off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. If others near East Hill need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Move anything stored against the joints
- Let us know about inductions and permits
- Explain the parking and delivery arrangements

How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- The size and state of each joint
- Which sealant the job calls for
- The total length or number of joints
- Travel to remote or island sites
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
Details that help us quote
A few photographs plus some basic facts will normally do. It helps to include:
- Rough lengths or quantities, or drawings if you have them
- The product your specification calls for
- What the building is and how it’s used
- Asbestos survey details if the building is older
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or send photos by email.
FAQs: East Hill
Is a smaller place like East Hill outside your area?
No. Places such as East Hill are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you work for managing agents with blocks near Shoreham (Kent) station?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
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.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

What we are called out for in East Hill
Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
Look out for the following:
- Damp patches beside frames
- Complaints coming in block by block
- Draught complaints from residents or tenants
- Mastic failing across several blocks on an estate
If you look after a block within reach of Shoreham (Kent) station (2.1 miles west of East Hill), frame and balcony mastic can be renewed on one programme.
Questions to ask before you book
- How the existing material will be dealt with
- Their plan for phasing and protecting the area
- How joint depth will be controlled
- What level of public liability insurance do they hold?
Leave it or put it right?
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Halls, stores and units around places like East Hill may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
