How we handle mastic sealing in Westham

Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. If you are dealing with the same joint failures repeated across a portfolio and draughts at frames across a block, we can help, on balcony and threshold joints, communal entrances and stairwells and shopfronts below residential blocks alike. Most enquiries from Westham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Rural conversions near places like Westham often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Common questions from Westham clients

Is Westham Industrial Estate, near Westham, within your area?

Yes. Estates, retail parks and business parks around Westham, Westham Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Do you work in occupied care homes around Westham?

Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.

Do you work in Westham?

Yes. Westham falls within our area, and the simplest way to start is to speak to us on 01277 525 020 or send photos by email.

What will the job cost?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

How do we ask for a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

How the quote is worked out

These are the things that shape the price:

  • How accessible the joints are
  • Whether the work must be split into stages
  • Quantities, in metres or numbers
  • Whether old sealant has to be cut out first

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Details that help us quote

To price the job accurately, we need a clear picture of the site. Send us:

  • Whether the building will be occupied during the work
  • The site address and postcode
  • How the joints are reached, and at what height
  • The product your specification calls for

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Avoid piecemeal callouts where you can
  • Log resealing dates block by block
  • Make it easy for occupiers to report draughts
  • Include mastic in your cyclical inspections

Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.

Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Westham are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Before we start on site

  • Send your site hours and access windows
  • Confirm the product named in the specification
  • Agree which areas must stay open

Building owners and managing agents use us on everything from one building to a spread of sites around Westham. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Planned mastic for Westham portfolios

Westham is within about 2 miles of the coast. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first. Westham is about 50 miles from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.

Schools and community buildings such as Pevensey and Westham CofE Primary School need frame and external mastic kept sound like any building. If you own or manage units on a site such as Westham Industrial Estate, which lies south-east of Westham, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Trustees of buildings like St Mary's Church can bring frame and external mastic into a planned maintenance list.

Westham is about 3 miles north-east of Eastbourne, in East Sussex. We cover Westham and the rest of East Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. Westham is one of 308 places in East Sussex on our list for mastic joints. There’s a separate page for Brighton, roughly 20 miles from Westham.

When something else is needed

We check first that sealant really is the fix. It won’t put right:

  • Water coming in from the roof or rainwater goods
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

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