Mastic sealing across Bapchild

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Mastic sealing in Bapchild

We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on shopfronts below residential blocks, external wall and movement joints and window and door perimeters on blocks, and the usual reasons a site gets in touch are the same joint failures repeated across a portfolio and failed external movement joints. One point of contact handles commercial sealant work in Bapchild from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Owners and agents with buildings around smaller places such as Bapchild tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

Our workmanship is guaranteed for 12 months, in Bapchild as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Building owners, agents and FMs in Bapchild

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Honest limits

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Materials that need asbestos testing before work
  • Leaks through the frame itself rather than the perimeter
  • Broken glass or failed sealed units

Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

What we seal

  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • Balcony and threshold joints
  • Window and door perimeters on blocks
  • External wall and movement joints
  • Communal kitchens and washrooms

Looking after the joints

After handover, a little attention goes a long way:

  • Start inspections with the most exposed faces
  • Keep a record of when each building was resealed
  • Check sealant joints during planned building inspections
  • Keep bins and bikes away from communal door frames

Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.

Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.

Diagnose, treat, sign off

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Smaller jobs around Bapchild can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Send your site hours and access windows
  • Point out parking and an unloading spot

How the job changes by surface

Tenement and older buildings

Traditional buildings have joints that need a careful approach. We look at the substrate before choosing a sealant.

External movement joints

Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.

Blocks and managed buildings in Bapchild

Bapchild is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. At about 39 miles from central London, Bapchild is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.

For agents with blocks near Teynham station, 2.1 miles north-east of Bapchild, a block-wide mastic programme deals with frames, balconies and entrances in one go. For a school such as Rodmersham School, perimeter mastic on windows and doors is a holiday job. Trustees of buildings like Church of St Nicholas can bring frame and external mastic into a planned maintenance list.

Bapchild is about 2 miles south-east of Sittingbourne, in Kent. We cover Bapchild, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 931 places in Kent, large and small. London is covered too, around 39 miles from Bapchild.

Bapchild: questions and answers

Will you take on a block within reach of Teynham station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

Is a smaller place like Bapchild outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

What paperwork can you provide?

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 will confirm with the quote.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
