Facade sealing for Bramshaw sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Building owners, agents and FMs in Bramshaw

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

How we handle facade sealing in Bramshaw

External joints face UV, rain, temperature swings and building movement all year. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. We work on cladding panel joints, window and door perimeters and shopfront frames, and the usual reasons a site gets in touch are unsightly perimeter sealant on a visible elevation and gaps between rainscreen or cladding panels. Whether you call it commercial sealant work, mastic application or joint sealing, in Bramshaw it comes down to the same thing: the right product in a properly prepared joint.

Around smaller places like Bramshaw, building work usually 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Surface by surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint, not the framing or glazing itself.

Signs you need facade sealing in Bramshaw

Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Things that normally lead to an enquiry:

  • Old perimeter mastic that has dried out
  • Staining on stone next to old sealant
  • Perimeter joints where frames meet the structure
  • Air leaks through failed facade joints

On a healthcare site such as Tatchbury Mount Hospital (4.1 miles east of Bramshaw), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
  • How they handle RAMS and site documents

Our contractor checklist

Aftercare for building managers

To get the most from the new sealant:

  • Check the asbestos register before old mastic is disturbed
  • Investigate damp beside windows promptly
  • Insist on a full cut-out when joints are renewed
  • Record the product and colour used on each elevation

After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Bramshaw are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements

Questions we’re asked in Bramshaw

Is a hospital such as Tatchbury Mount Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Bramshaw too far out for you?

No. Places such as Bramshaw are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Is old mastic on our building likely to contain asbestos?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you run new sealant over the existing bead?

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

Why deal with it now?

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Around Bramshaw, 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.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Why appoint us

  • Colour agreed before work starts
  • Colours chosen to suit frames, cladding or finishes where possible

Sites and facades in and around Bramshaw

Rainfall across the South East, Bramshaw included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.

For contractors refurbishing units at places like Giles Lane Industrial Estate, 2.3 miles to the north of Bramshaw, the mastic covers cladding panels, roller-door and window perimeters. Hotel extensions and refits, at places such as Bramble Hill Hotel, 0.6 miles south-west of Bramshaw, usually run between busy periods, so the sealing is squeezed into short windows.
