Looking after buildings in and around Bishopsbourne

Bishopsbourne lies roughly 56 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. Rainfall across the South East, Bishopsbourne included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

Property owners at sites such as Canterbury Business Park, 0.8 miles north-east of Bishopsbourne, can have mastic renewed between lettings. With historic buildings such as Goodnestone Park, 4.1 miles to the east of Bishopsbourne, in the wider area, owners of older properties around Bishopsbourne should expect mastic to need a product that suits old masonry. If you look after a block within reach of Bekesbourne station (2.2 miles north of Bishopsbourne), frame and balcony mastic can be renewed on one programme.

Bishopsbourne is about 4 miles south-east of Canterbury, in Kent. Any commercial site in Bishopsbourne is covered, for single jobs and planned programmes alike. Bishopsbourne is one of 931 places in Kent on our list. There’s a separate page for London, about 56 miles away.

We also cover Kingston (1 mile south-east), Bridge (1 mile north), Out Elmstead (1 mile south-east), Marley (1 mile south) and Patrixbourne (2 miles north) for mastic joints. Further afield, our area takes in Ashford (13 miles south-west), Canterbury (4 miles north-west), Margate (15 miles north-east), Dover (10 miles south-east), Folkestone (10 miles south) and Ramsgate (14 miles north-east).

Mastic sealing for commercial buildings in Bishopsbourne

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms, and the failures we’re asked to look at most are worn sealant at communal door frames and open joints in brickwork or panels. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Bishopsbourne, that means joint design, primers and backing rod as standard.

Rural conversions near places like Bishopsbourne often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Why it’s worth doing now in Bishopsbourne

Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. One visit to deal with every failing joint makes more sense than several trips to a place like Bishopsbourne, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Yes. We cover Bishopsbourne. For a quote, ring 01277 525 020 or email the details over.

How long before the joints can be used?

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.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How long does a typical visit take?

It depends on the scope, but the work normally takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.

What the job involves on each surface

Communal areas

Low-level communal joints get damaged more than most, so they often need renewing sooner.

Estate-wide resealing programmes

Priority order can follow condition, complaints or your maintenance plan. Quotes can be per block or for the full programme.

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Masonry that has broken away beside the joint
  • Failed window or door frames, which need a window contractor

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly.

Where we work in Bishopsbourne

  • Balcony and threshold joints
  • Window and door perimeters on blocks

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Group repairs into a planned programme
  • Start inspections with the most exposed faces
  • Track which buildings were done and when
  • Check the asbestos register before any old mastic is disturbed

Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
