Contractors’ notes for Five Ashes

At about 37 miles from central London, Five Ashes is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Five Ashes sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

When a school such as Five Ashes CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Hospital estates such as Crowborough War Memorial Hospital (4.3 miles north-west of Five Ashes) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Five Ashes is about 4 miles south-east of Crowborough, in East Sussex. We cover Five Ashes, with the same fixed quotes and 12-month guarantee as everywhere else. Five Ashes is one of 308 places we cover in East Sussex for facade joints. Brighton is covered too, some 19 miles away.

Facade sealing for commercial buildings in Five Ashes

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces. We work on window and door perimeters, coping and flashing joints and shopfront frames, and what we’re called in for most is air leaks through failed facade joints and old perimeter mastic that has dried out. A single leaking joint is often how a building in Five Ashes first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In the countryside around places like Five Ashes, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions about Five Ashes

Can you take on a job at a hospital such as Crowborough War Memorial Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you cover business parks and estates near Five Ashes, such as Station Road Industrial Estate?

Yes. Our area takes in Five Ashes and its surroundings, with estates and business parks such as Station Road Industrial Estate included. Photos and a short description are enough for a first look.

How long does a typical visit take?

It depends on the scope, though a typical visit normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

How do we ask for a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email the details over. Include photos or drawings if you have them.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. Jobs in and around smaller places like Five Ashes are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits
  • Point out parking and an unloading spot

Building owners, agents and FMs in Five Ashes

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

What we can’t put right

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

  • Damp caused by condensation inside the building
  • Cracked or spalling substrates that need repair before sealing
  • Joints whose design needs changing by the specifier

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think.

Where we work in Five Ashes

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

Different surfaces, different methods

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.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

When to call us in Five Ashes

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.

Common reasons buildings call us in:

  • Discoloured or dirty facade joints
  • Perimeter sealant that has split or peeled away
  • Weathered facade joints that have lost their grip
  • Gaps between rainscreen or cladding panels

For contractors refurbishing units at places like Station Road Industrial Estate, which lies south-east of Five Ashes, the mastic covers cladding panels, roller-door and window perimeters.
