Mastic sealing for Barcombe Cross sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Mastic sealing for commercial buildings in Barcombe Cross

Across Barcombe Cross and the rest of East Sussex, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. We work on communal kitchens and washrooms, window and door perimeters on blocks and shopfronts below residential blocks, and the failures we are asked to look at most are no planned programme for sealant and draught complaints from residents or tenants. A single leaking joint is often how a building in Barcombe Cross first comes to us: we look at the rest while we’re there and tell you what we find.

In and around smaller places like Barcombe Cross, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Keeping the joints sound

After handover, these steps help:

  • Log resealing dates block by block
  • Share your contractor requirements early
  • Encourage occupiers to report problems at frames
  • Reduce knocks to communal area joints

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

Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Questions we’re asked in Barcombe Cross

Can you work at a site such as Diplocks industrial estate, by Barcombe Cross?

Yes. Estates, retail parks and business parks around Barcombe Cross, Diplocks industrial estate among them, are all within reach. Photos and a short description are enough for a first look.

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

Yes, and several blocks can go on one quote. We work to your notice and access arrangements.

Do you check for asbestos in old sealant?

Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Can you take on resealing for a block portfolio?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Can you plan resealing across several buildings?

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

What guarantee do you give on resealing?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.

Commercial clients in Barcombe Cross

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Surface by surface

Tenement and older buildings

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

Communal areas

We keep entrances and stairs open throughout. Work is planned in sections.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Quantities, in metres or numbers
  • Removal of failed or old sealant
  • Access and working height
  • Distance, for remote addresses

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.

What we need to price the job

A few photographs plus some basic facts will normally do. Please tell us:

  • Your programme or deadline
  • How the joints are reached, and at what height
  • The asbestos register, for older buildings
  • What the building is and how it’s used

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

For owners and agents in Barcombe Cross

Central London is about 40 miles from Barcombe Cross. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Barcombe Cross is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

Site managers at schools like Barcombe Church of England Primary School can fit frame mastic into the summer works. Older community buildings, St Francis of Assisi among them, often have frames of mixed ages whose mastic varies. Blocks of flats and mixed-use buildings often cluster around stations such as Cooksbridge station (to the south-west of Barcombe Cross) and their window and balcony mastic tends to age at the same rate across a building.

Barcombe Cross is about 3 miles north of Lewes, in East Sussex. We send applicators to Barcombe Cross for mastic joints. Across East Sussex, 308 places are covered, including Barcombe Cross. Brighton is covered too, around 9 miles from Barcombe Cross.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Leaks from above rather than through a joint
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Glazing that needs replacing

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think before you book.

Surfaces we seal

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

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Barcombe Cross, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Getting the site ready

  • Tell us which areas need to stay in use
  • Move anything stored against the joints
  • Warn occupants and staff about the work
