How we handle facade sealing in Langney

Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. We work on window and door perimeters, stone and brick facade joints and cladding panel joints, and what we’re called in for most is air leaks through failed facade joints and weathered joints at frame-to-structure perimeters. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Langney it comes down to the same thing: the right product in a properly prepared joint.

Building work in places the size of Langney is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Should maintenance staff do it?

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 where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What happens if it’s left?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Small buildings around Langney suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Mastic packages on Langney sites

Langney sits close to the coast, within about 2 miles. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. Langney is about 51 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Units on estates such as Sovereign Harbour Village Retail Park, 0.5 miles south-east of Langney, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Building work at universities like University of Brighton Eastbourne Campus (3.9 miles south-west of Langney) is often timed for the summer, mastic included. On a healthcare site such as Eastbourne District General Hospital (2.2 miles south-west of Langney), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Langney is about 2 miles north-east of Eastbourne, in East Sussex. Businesses, contractors and managing agents in Langney use us for work on facade joints. Langney is one of 308 places in East Sussex on our list for facade joints. There’s a separate page for Brighton, roughly 20 miles from Langney.

How the job changes by surface

Precast concrete panels

Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported.

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, with masked edges for a clean line.

When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Providing access systems for the work
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints whose design needs changing by the specifier

If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think.

Where we work in Langney

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

Langney: questions and answers

Is Langney off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Is Sovereign Harbour Village Retail Park, near Langney, within your area?

Yes. Estates, retail parks and business parks around Langney, Sovereign Harbour Village Retail Park among them, are all within reach. A few photographs and the unit address let us price the work.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

How a job runs

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 we check in with your contact before moving on to each new area. Several jobs near Langney can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. Access, site rules and timing are settled with the client up front.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Investigate damp beside windows promptly
  • Combine resealing with other works that need access
  • Ask about asbestos in pre-2000 mastic
  • Record the product and colour used on each elevation

Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.
