Mastic sealing in Sibertswold, done properly
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable throughout. If you have brittle perimeter mastic across a building and patchy repairs in mismatched sealant, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Sibertswold it comes down to the same thing: the right product in a properly prepared joint.
In and around smaller places like Sibertswold, 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.

Looking after buildings in and around Sibertswold
Sibertswold is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Sibertswold is about 61 miles 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.
With historic buildings such as Goodnestone Park, 3.9 miles to the north of Sibertswold, in the wider area, owners of older properties around Sibertswold should expect mastic to need a product that suits old masonry. Blocks of flats and mixed-use buildings often cluster around stations such as Shepherds Well station, under half a mile to the west of Sibertswold, and their window and balcony mastic tends to age at the same rate across a building.
Sibertswold (also: Shepherdswell) is about 4 miles north-west of Dover, in Kent. We cover commercial sites throughout Sibertswold, for single jobs and planned programmes alike. We work across 931 places in Kent, from busy centres to rural villages. Our London page has more on work in that area.

Questions about Sibertswold
Is Sibertswold too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Do you work for managing agents with blocks near Shepherds Well station?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
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 will confirm with the quote.
Why it’s worth doing now in Sibertswold
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Older rural buildings around Sibertswold move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Share your contractor requirements early
- Check the asbestos register before any old mastic is disturbed
- Include mastic in your cyclical inspections
- Encourage occupiers to report problems at frames
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For work around Sibertswold, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Getting the site ready

- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand
Get a fixed quote

What we’re called out for in Sibertswold
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
It’s worth sending us details if you spot any of the following:
- Brittle perimeter mastic across a building
- Occupiers reporting cold air round windows
- Communal area joints that look neglected
- Damp patches beside frames
Older community buildings, Church of St Andrew among them, often have frames of mixed ages whose mastic varies.
