- Frames that are rotten, warped or broken
- Materials that need asbestos testing before work
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

- Window and door perimeters on blocks
- Balcony and threshold joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Shopfronts below residential blocks
How we handle mastic sealing in Broad Street
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. 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, shopfronts below residential blocks and external wall and movement joints, and the failures we are asked to look at most are complaints coming in block by block and draughts at frames across a block. Most enquiries from Broad Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Rural conversions near places like Broad Street 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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

For owners and agents in Broad Street
Broad Street lies roughly 34 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Rainfall across the South East, Broad Street included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
Owners of student blocks near Canterbury Christ Church University (2.6 miles east of Broad Street) can schedule frame and external mastic for the summer vacation. For agents with blocks near Hollingbourne station, 1.1 miles south of Broad Street, a block-wide mastic programme deals with frames, balconies and entrances in one go. Historic properties like Leeds Castle (2.3 miles south of Broad Street) show the age of some local stock, where frame mastic must suit soft brick or stone.

Different surfaces, different methods
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above the programme has to suit everyone. Tell us your site hours and access windows and we’ll plan around them.
Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Check sealant joints during planned building inspections
- Encourage occupiers to report problems at frames
- Mention RAMS, insurance or CSCS requirements up front
- 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 note the building and elevation.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.
Why act early in Broad Street
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. One visit to deal with every failing joint makes more sense than several trips to a place like Broad Street. Photos of every joint help us quote for the whole job.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

FAQs: Broad Street
Is a smaller place like Broad Street outside your area?
No. Places such as Broad Street are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Will you take on a block within reach of Hollingbourne station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
How long does a job like this take?
It depends on the scope, but the work usually takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Do you do block-wide mastic programmes?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
