Mastic sealing for commercial buildings in Teynham
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. We work on communal entrances and stairwells, shopfronts below residential blocks and window and door perimeters on blocks, and what we’re called in for most is a mix of products and colours from past repairs and failed external movement joints. Looking for mastic applicators who cover Teynham? We have been sealing commercial buildings since 2005.
Older buildings and conversions around places like Teynham mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Leave it or put it right?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and typically fails within a short time. Full removal and proper preparation is what lasts. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Do you need mastic sealing in Teynham?
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
Most enquiries start with one or more of the following:
- A mix of products and colours from past repairs
- Cracked, hardened mastic round windows on a block
- Mastic failing across several blocks on an estate
- Repeated reactive repairs to the same buildings
Older community buildings, Church of St Mary among them, often have frames of mixed ages whose mastic varies.

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. What matters most for a job in Teynham is a clear list of what needs doing. A fixed quote follows.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Send any specification or drawings in advance
- Point out parking and an unloading spot
- For older buildings, check the asbestos register before work
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Our job is the joint, not everything around it. Sealant alone won’t deal with:

- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Misted or failed double-glazed units
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly.
What we seal

What the job involves on each surface
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. You get one fixed quote per building or for the whole estate.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
Frames, entrances and external joints in Teynham
Teynham is within about 3 miles of the coast. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. Central London is about 40 miles from Teynham. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate.
For a school such as Teynham Parochial Church of England Primary School, perimeter mastic on windows and doors is a holiday job. Blocks of flats and mixed-use buildings often cluster around stations such as Teynham station (to the north-east of Teynham) and their window and balcony mastic tends to age at the same rate across a building.

Common questions from Teynham clients
Will you take on a block within reach of Teynham station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is Teynham off your patch?
No. Places such as Teynham are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can people stay in the building while you reseal?
The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Do you supply RAMS and insurance details?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
