What we’re called out for in West Cross

Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.

It’s worth sending us details if you spot any of the following:

  • Leaks at window and door perimeters
  • Brittle perimeter mastic across a building
  • The same joint failures repeated across a portfolio
  • Open joints in brickwork or panels

Schools and community buildings such as Rolvenden Primary School need frame and external mastic kept sound like any building.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • The terms of the workmanship guarantee
  • How the joint faces will be prepared and primed
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Mastic sealing in West Cross, done properly

Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. We work on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells, and what we’re called in for most is no planned programme for sealant and water getting in round frames after rain. A single leaking joint is often how a building in West Cross first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For owners with a single building near West Cross, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Leaks through the frame itself rather than the perimeter
  • Materials that need asbestos testing before work

If you’re not sure, just call 01277 525 020 or email the details over and we will give you a straight answer.

Where we work in West Cross

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

Block-wide mastic in West Cross

The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. West Cross lies roughly 43 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.

Historic properties like Smallhythe Place (3.7 miles east of West Cross) show the age of some local stock, where frame mastic must suit soft brick or stone. Property owners at sites such as Business Park, 2.3 miles to the north-east of West Cross, can have mastic renewed between lettings.

Related advice

After the work

For the best life from the joints:

  • Mention RAMS, insurance or CSCS requirements up front
  • Log resealing dates block by block
  • Check sealant joints during planned building inspections
  • Keep bins and bikes away from communal door frames

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
