Facade sealing for South Chailey sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Do you need facade sealing in South Chailey?

When the sealant tears down its centre, it has usually been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

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

  • Gaps between rainscreen or cladding panels
  • Perimeter sealant that has split or peeled away
  • Discoloured or dirty facade joints
  • Air leaks through failed facade joints

For contractors refurbishing units at places like Park Farm Business Park (2.6 miles west of South Chailey), the mastic covers cladding panels, roller-door and window perimeters.

What your quote should include

  • How joint depth will be controlled
  • What site paperwork they can supply
  • Their plan for phasing and protecting the area
  • How long is the guarantee, and what does it include?

Our contractor checklist

Facade sealing in South Chailey

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. We work on shopfront frames, stone and brick facade joints and coping and flashing joints, and the failures we are asked to look at most are hard, chalky sealant that no longer flexes and sealant pulling away from frames or panels. Whether you call it commercial sealant work, mastic application or joint sealing, the work in South Chailey is the same: the right product in a properly prepared joint.

Around smaller places like South Chailey, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Work we carry out in East Sussex comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email us and we’ll arrange a return visit.

Surface by surface

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint, not the framing or glazing itself.

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Movement beyond what any sealant can handle
  • Render or concrete edges that have broken away
  • Water getting in through cracked render or porous masonry

If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think.

What we seal

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

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around South Chailey, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Send any specification or drawings in advance
  • Arrange parking or a loading space
  • Send your site hours and access windows

Why it’s worth doing now in South Chailey

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Around South Chailey, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why appoint us

  • Colours chosen to suit frames, cladding or finishes where possible
  • CHAS accredited
  • 12-month guarantee on workmanship
  • Old sealant cut out, never sealed over

Facade sealing in South Chailey: the local picture

South Chailey is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. South Chailey is about 39 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

School extensions, at buildings such as Chailey School, typically run to the summer holidays, mastic included. On a campus such as University of Sussex, which lies north of South Chailey, new teaching buildings and residences are normally built and refurbished around the academic year.

South Chailey is about 4 miles north of Lewes, in East Sussex. We cover commercial sites throughout South Chailey, for single jobs and planned programmes alike. Our East Sussex coverage takes in 308 places. Sites around Brighton have their own page, roughly 9 miles from South Chailey.

We cover the BN8 postcode districts for facade joints. For a building on Mill Brooks, Whitegates Close and Brickyard Lane or nearby, send details and we’ll quote for facade joints. If your building is just outside South Chailey, we cover South Street (1 mile north), Chiltington (1 mile south), Chailey (2 miles north-east), East Chiltington (2 miles south-west) and Plumpton Green (2 miles west). Nearby towns on our patch include Seaford (13 miles south-east), Lewes (4 miles south), Hailsham (13 miles south-east), Crowborough (11 miles north-east), Uckfield (6 miles east) and Newhaven (11 miles south).

Questions we’re asked in South Chailey

Is hospital work, at somewhere like Lewes Victoria Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Could you schedule work at a campus like University of Sussex for the vacation?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Can you just add new sealant on top?

No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. Nothing else gives a bond that lasts.

How is access to upper-level joints handled?

We agree access with the client at the start. Let us know what access is in place or planned, and we’ll price the work around it.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

For managing agents and facilities managers

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

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.
