Signs you need mastic sealing in Broxted

We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.

These are often picked up first by site or facilities staff:

  • Water getting in round frames after rain
  • Draught complaints from residents or tenants
  • Open joints in brickwork or panels
  • Old repairs sealed over failed mastic

If you look after a block within reach of Stansted Airport station, which lies south-west of Broxted, frame and balcony mastic can be renewed on one programme.

Choosing a commercial sealant contractor

Mastic sealing in Broxted

Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. Site teams most often ask us about complaints coming in block by block and the same joint failures repeated across a portfolio, on shopfronts below residential blocks, communal entrances and stairwells and window and door perimeters on blocks. For commercial sealant work in Broxted, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In and around smaller places like Broxted, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Frames, entrances and external joints in Broxted

Broxted 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 usually need attention first. Broxted is about 34 miles from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate.

Churches, halls and community buildings such as Church of St Mary the Virgin are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. With historic buildings such as Horham Hall (to the north-east of Broxted) in the wider area, owners of older properties around Broxted should expect mastic to need a product that suits old masonry.

Broxted is about 7 miles north-east of Bishop's Stortford, in Essex. We cover Broxted, with the same fixed quotes and 12-month guarantee as everywhere else. Across Essex, 644 places are covered, Broxted among them. For work in that direction, see our London page.

We cover the CM6 postcode districts for mastic joints. For a building on St Mary's Mews and Cranham Road or nearby, we can quote for mastic joints. Nearby places we also cover include Brick End (1 mile south), Henham (2 miles west), Debden Green (3 miles north), Fuller's End (3 miles west) and Elsenham (3 miles west). Bigger towns within reach include Chelmsford (15 miles south-east), Braintree (12 miles east), Harlow (13 miles south-west), Saffron Walden (7 miles north), Halstead (15 miles east) and Great Dunmow (4 miles south-east).

What’s near Broxted

The nearest railway station is Stansted Airport station, about 2.7 miles south-west. Other landmarks nearby include Little Easton Moat (2.9 miles south-east). For a walk, there’s Aubrey Buxton Nature Reserve.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Failed window or door frames, which need a window contractor
  • Glazing that needs replacing
  • Masonry that has broken away beside the joint

If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think before you book.

Surfaces we seal

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

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Jobs in and around smaller places like Broxted are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. A building-by-building inspection lists the failed joints.
  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. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

What we need from you

  • Agree which areas must stay open
  • Confirm the product named in the specification
  • Tell us your opening times and when work is allowed

How the job changes by surface

Communal areas

We keep entrances and stairs open throughout. We work in sections so access is never blocked.

Window and door perimeters on blocks

Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.

Aftercare for building managers

For the best life from the joints:

  • Protect low-level joints in entrances
  • Plan resealing building by building rather than complaint by complaint
  • Encourage occupiers to report problems at frames
  • Include mastic in your cyclical inspections

Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Questions we are asked in Broxted

Can you quote for a block close to Stansted Airport station?

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

Can you work at a site such as Williams Field Business Centre, by Broxted?

Yes, sites like Williams Field Business Centre are within our area, along with the rest of Broxted. Photos and a short description are enough for a first look.

How long does a job like this take?

It depends on the scope, though a typical visit usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Does the weather affect the work?

Outside, 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.

Can you plan resealing across several buildings?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
