Mastic sealing for Bowmans sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Mastic sealing in Bowmans, done properly

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Bowmans carry our 12-month guarantee. If you have cracked, hardened mastic round windows on a block and old repairs sealed over failed mastic, we can put it right, whatever the surface. For commercial sealant work in Bowmans, you deal with one contact from quote to sign-off, whether it’s one building or several.

Converted and older buildings in and around Bowmans often put modern windows into old walls. The mastic there needs to suit both surfaces.

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

Quoting for work in Bowmans

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Any access equipment needed
  • Backing rod, priming and other preparation
  • Which sealant the job calls for
  • Removal of failed or old sealant

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Sending details for a quote

However big the job, the same details help:

  • A wide shot and a close-up of the area
  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • The asbestos register, for older buildings

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Surface by surface

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.

Window and door perimeters on blocks

Perimeter joints on blocks are best done elevation by elevation or block by block. How each joint is reached is agreed at quote stage.

Block-wide mastic in Bowmans

Bowmans is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first. At about 13 miles from central London, Bowmans is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.

Older community buildings, St Barnabas among them, often have frames of mixed ages whose mastic varies. Landlords with units on estates such as Tower Retail Park, 0.8 miles to the north of Bowmans, can bring frame, door and external mastic across several units into one programme.

Bowmans is about 2 miles west of Dartford, in Kent. We cover commercial sites throughout Bowmans, for single jobs and planned programmes alike. We work across 931 places in Kent. London is covered too, around 13 miles from Bowmans.

We cover the DA1, DA2 and DA5 postcode districts. Among the streets we cover are Swan Lane, Dale Road and Ross Road. Bowmans sits on or close to the A2018, which helps when planning parking and deliveries for the job. We also cover Wilmington (1 mile south), Crayford (1 mile north), Coldblow (1 mile west), Joyden's Wood (1 mile south-west) and Barnes Cray (1 mile north-east). Further afield, our area takes in Sevenoaks (11 miles south), Gravesend (9 miles east), Northfleet (7 miles east), Swanley (3 miles south), Kings Hill (15 miles south-east) and Swanscombe (5 miles east).

Landmarks near Bowmans

We work on buildings around Wilmington Grammar School for Girls, Bird in Hand pub and St Columba's Catholic Boys' School, among other places. The closest station to Bowmans is Crayford station, about 0.6 miles north. Nearby you will also find Stone Castle (4.1 miles east) and West Hill Hospital (1.3 miles east).

After the work

To get the most from the new sealant:

  • Make mastic part of routine maintenance checks
  • Ask residents or tenants to report leaks and draughts early
  • Log resealing dates block by block
  • Share the asbestos register when you send details

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.

Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.

Bowmans: questions and answers

Is Tower Retail Park, near Bowmans, within your area?

Yes. Our area takes in Bowmans and its surroundings, with estates and business parks such as Tower Retail Park included. A few photographs and the unit address let us price the work.

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

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

How long does a typical visit take?

It depends on the scope, though a typical visit typically takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so it can be arranged.

Can you seal joints high up on a block?

It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you need mastic sealing in Bowmans?

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.

Most enquiries start with one or more of the following:

  • Window mastic that has split and shrunk
  • Movement joints with sealant missing
  • The same joint failures repeated across a portfolio
  • Communal area joints that look neglected

For a school such as Wentworth Primary School, perimeter mastic on windows and doors is a holiday job.

Before you book anyone

  • How they’ll work around occupants
  • Whether old or failed sealant will be cut out, not overlaid
  • How joint depth will be controlled
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Glazing that needs replacing
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Frames that are rotten, warped or broken

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Work in places the size of Bowmans is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Tell us what induction or permit system the site runs
  • Clear stock, furniture or equipment away from the joints

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
