Mastic sealing in Brabourne

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

Cost factors for mastic joints

Your fixed quote is built from the real scope. It takes account of:

  • How much there is to seal
  • Phasing around occupants
  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

What we need to price the job

There’s no need for a formal survey. A few details are enough to get going:

  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode
  • The product your specification calls for

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email a schedule or drawings.

Leave it or put it right?

Failed perimeter mastic lets cold air in around frames and the windows normally get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Halls, stores and units around places like Brabourne may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why appoint us

  • Clear, fixed quotes
  • Joints cleaned back to sound surfaces
  • One phone line for London, the South East and Scotland
  • Standard and matched colours in many product ranges

Different surfaces, different methods

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler.

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Blocks and managed buildings in Brabourne

Brabourne is about 53 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Brabourne sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

Older buildings near Brabourne, from historic houses such as Westenhanger Castle, 3.3 miles south-east of Brabourne, to more modest stock, need compatible products when frames are resealed. For a school such as Brabourne Church of England Primary School, perimeter mastic on windows and doors is a holiday job.

Brabourne is about 6 miles east of Ashford, in Kent. We send applicators to Brabourne for mastic joints. We work across 931 places in Kent. Sites around London have their own page, roughly 53 miles from Brabourne.

What we are called out for in Brabourne

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Cleaning products add to the wear.

Things that usually lead to an enquiry:

  • Worn sealant at communal door frames
  • Brittle perimeter mastic across a building
  • Repeated reactive repairs to the same buildings
  • Water getting in round frames after rain

Blocks of flats and mixed-use buildings often cluster around stations such as Westenhanger station, 3.4 miles to the south-east of Brabourne, and their window and balcony mastic tends to age at the same rate across a building.

  • How they handle RAMS and site documents
  • Whether old or failed sealant will be cut out, not overlaid
  • Who will actually carry out the work

FAQs: Brabourne

Is Brabourne off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work at a site such as Evegate Business Park, by Brabourne?

Yes. Estates, retail parks and business parks around Brabourne, Evegate Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

How do you handle work on occupied blocks?

The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.

On site: what to expect

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Brabourne can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification
  • Tell staff and tenants when we will be in

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
