Facade sealing around West Stourmouth: what changes locally

West Stourmouth is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. At about 59 miles from central London, West Stourmouth is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

For contractors at a school such as Preston Primary School, sealing has to be finished before term starts. When units on a site such as Canterbury Industrial Park, 2.6 miles west of West Stourmouth, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

West Stourmouth is about 6 miles south-east of Herne Bay, in Kent. Commercial clients in West Stourmouth can call on us for facade joints. 931 places across Kent fall within our area, including West Stourmouth. There’s a separate page for London, about 59 miles away.

How we handle facade sealing in West Stourmouth

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. The enquiries we see most involve cold air coming in at window perimeters and failed sealant on precast panel joints, on perimeter joints where frames meet the structure, coping and flashing joints and cladding panel joints. Whoever orders the work in West Stourmouth, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

For a site near West Stourmouth, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Keep the sealant details on the building file
  • Insist on a full cut-out when joints are renewed
  • Investigate damp beside windows promptly
  • Inspect facade joints on a regular cycle

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down and cuts time on site.

Surface by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed with a product suited to glazing perimeters.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Smaller jobs around West Stourmouth can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Flag any permit to work we’ll need

Advice

Questions we are asked in West Stourmouth

Can you keep pace with our programme in West Stourmouth?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a smaller place like West Stourmouth outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Do you have public liability insurance?

Yes. Mastic Doctor is fully insured, public liability included.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Honest limits

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Installing or repairing glazing systems
  • Providing access systems for the work
  • Joints whose design needs changing by the specifier

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

Surfaces we seal

  • Stone and brick facade joints
  • Cladding panel joints
  • Coping and flashing joints
  • Perimeter joints where frames meet the structure
  • Window and door perimeters
  • Shopfront frames

Quoting for work in West Stourmouth

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

  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • Any access equipment needed
  • Location, for remote and island sites

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • Photos of the joints, close up and from further back
  • The site address and postcode
  • Access details, including height
  • Specification clauses that apply

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Common problems we fix in West Stourmouth

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

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

  • Air leaks through failed facade joints
  • Hard, chalky sealant that no longer flexes
  • Unsightly perimeter sealant on a visible elevation
  • Patch repairs that keep failing

Hotels like Sarre Court Hotel (to the north of West Stourmouth) rarely close for long, so refurbishment mastic is phased floor by floor.

Questions to ask before you book

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?
  • Their public liability cover
