Facade sealing for Dukes Green sites

Facade sealing for commercial buildings in Dukes Green

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. We work on stone and brick facade joints, window and door perimeters and coping and flashing joints, and the usual reasons a site gets in touch are draughts around frames and panels and damp patches beside frames after rain. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Dukes Green, preparation and product choice get the time they need.

Construction in and around smaller places such as Dukes Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Quoting for work in Dukes Green

Your fixed quote is built from the real scope. It takes account of:

  • Phasing around occupants
  • Which sealant the job calls for
  • Induction, permit and paperwork requirements
  • Distance, for remote addresses

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • Clear photos of the problem areas
  • Your programme or deadline
  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Diagnose, treat, 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 move on in phases so staff and visitors can carry on around us. For work around Dukes Green, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  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. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Have the specification and drawings to hand
  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work

Why act early in Dukes Green

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. One visit to deal with every failing joint makes more sense than several trips to a place like Dukes Green, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Pricing facade joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Questions we are asked in Dukes Green

Can you work on a hospital site such as Chailey Heritage Marine Hospital?

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

Does your area include sites such as Berwick Court Farm Business Park, near Dukes Green?

Yes. We cover Dukes Green and the area around it, including industrial estates, business parks and retail parks such as Berwick Court Farm Business Park. Photos and a short description are enough for a first look.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can staff carry on working while you’re here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Is old mastic on our building likely to contain asbestos?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.

Is it fine to apply new sealant on top of old?

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

Building owners, agents and FMs in Dukes Green

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Contractors’ notes for Dukes Green

With the shore within about 3 miles, Dukes Green counts as a coastal location. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Rainfall across the South East, Dukes Green included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

When a school such as Alfriston School is extended or refurbished, the mastic package is often squeezed into the holidays. Hotel extensions and refits, at places such as Dean's Place Hotel (under half a mile north of Dukes Green), usually run between busy periods, so the sealing is squeezed into short windows.

What we are called out for in Dukes Green

Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.

Typical triggers for a call:

  • Perimeter joints where frames meet the structure
  • Air leaks through failed facade joints
  • Sealant pulling away from frames or panels
  • Cladding panel joints that have opened up

For a contractor working at a hospital such as Chailey Heritage Marine Hospital (3.8 miles west of Dukes Green), perimeter and facade sealing is planned around patients and deliveries.

Before you book anyone

  • How the joint faces will be prepared and primed
  • Whether old or failed sealant will be cut out, not overlaid
  • Their public liability cover
  • How they’ll work around occupants

How to choose a sealant contractor

Honest limits

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

  • Providing access systems for the work
  • Movement beyond what any sealant can handle
  • Render or concrete edges that have broken away

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