Mastic sealing in Newbury's
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Maintenance after handover
To get the most from the new sealant:
- Keep a record of when each building was resealed
- Share your contractor requirements early
- Share the asbestos register when you send details
- Make mastic part of routine maintenance checks
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
About our mastic sealing in Newbury's
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. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. If you are dealing with damaged joints in communal entrances and corridors and estate-wide sealant that is simply worn out, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Newbury's it comes down to the same thing: the right product in a properly prepared joint.
In and around smaller places like Newbury's, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Work we carry out in East Sussex comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send details through our quote form and we’ll come back to it.

Newbury's: questions and answers
Is Newbury's too far out for you?
Not at all. Newbury's is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you take on a block within reach of Wadhurst station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
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’ll confirm the curing time on the day.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, 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 the job involves on each surface
Window and door perimeters on blocks
Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Frames, entrances and external joints in Newbury's
Newbury's sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 35 miles from central London, Newbury's is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.
Buildings close to stations like Wadhurst station, 1.9 miles to the west of Newbury's, are often flats over shops, with frame mastic to keep sound. If you own or manage units on a site such as Durgates Industrial Estate, which lies south-west of Newbury's, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. For a school such as Uplands Community College, perimeter mastic on windows and doors is a holiday job.

For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Leaks from above rather than through a joint
- Misted or failed double-glazed units
- Masonry that has broken away beside the joint
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
