About our facade sealing in Lunsford's Cross

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. We work on window and door perimeters, coping and flashing joints and shopfront frames, and the usual reasons a site gets in touch are perimeter sealant that has split or peeled away and weathered joints at frame-to-structure perimeters. Most enquiries from Lunsford's Cross 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.

Conversions of older rural buildings near smaller places such as Lunsford's Cross bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Your questions answered

Is a smaller place like Lunsford's Cross outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work on a hospital site such as Bexhill Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

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.

Will you check whether the sealant is causing the leak?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

Can you just add new sealant on top?

No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.

Common problems we fix in Lunsford's Cross

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

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

  • Old perimeter mastic that has dried out
  • New sealant peeling off old mastic
  • Unsightly perimeter sealant on a visible elevation
  • Water coming in around window frames

Extensions at sites like Bexhill Hospital (to the south-east of Lunsford's Cross) typically sit beside working departments, and the mastic follows strict access rules.

What to look for in a quote

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they handle RAMS and site documents
  • The terms of the workmanship guarantee
  • Whether old or failed sealant will be cut out, not overlaid

How to choose a sealant contractor

Should maintenance staff do it?

Redoing a failed joint usually costs more than getting it right at the outset, 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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Installing or repairing glazing systems
  • Render or concrete edges that have broken away
  • Specialist high-level access methods

If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Commercial clients in Lunsford's Cross

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lunsford's Cross can sit alongside others in a wider programme.

Looking after the joints

A few simple habits keep the new joints working:

  • Confirm the survey covers external sealants in older buildings
  • Combine resealing with other works that need access
  • Investigate damp beside windows promptly
  • Avoid harsh cleaners on facade sealant

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal without guesswork.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.

Sites and facades in and around Lunsford's Cross

With the shore within about 3 miles, Lunsford's Cross counts as a coastal location. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Lunsford's Cross is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

When a school such as Ninfield Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Projects at colleges like Bexhill 6th Form College, 2.8 miles south-east of Lunsford's Cross, tend to run to term dates, so the mastic is planned tightly.
