Facade sealing for Five Ash Down sites

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

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Joints too narrow for the movement they take, which need redesign
  • Replacing glass or failed glazing units
  • Water getting in through cracked render or porous masonry

If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Joints and surfaces we work on

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

How we handle facade sealing in Five Ash Down

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. Most enquiries involve new sealant peeling off old mastic and staining on stone next to old sealant, across window and door perimeters, perimeter joints where frames meet the structure and stone and brick facade joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Five Ash Down it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Five Ash Down, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we will quote to suit.

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.

Why it’s worth doing now in Five Ash Down

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Older rural buildings around Five Ash Down move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

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

New build and refits around Five Ash Down

Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

Diagnose, treat, sign off

Diagnose, treat, sign off: every visit follows that pattern.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  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. We go over the completed work with you before leaving.

Preparing the site

When to call us in Five Ash Down

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained.

What tends to prompt an enquiry:

  • Unsightly perimeter sealant on a visible elevation
  • Old perimeter mastic that has dried out
  • Cold air coming in at window perimeters
  • Failed seals around shopfront and entrance frames

Projects at schools like Buxted CofE Primary School work to term dates, so mastic is programmed tightly.

What your quote should include

  • How the joint faces will be prepared and primed
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether old or failed sealant will be cut out, not overlaid
  • How they handle RAMS and site documents

How to choose a sealant contractor

When to bring in a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Questions about Five Ash Down

Can you work on a hospital site such as Uckfield Community Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Ashdown Business Park, near Five Ash Down?

Yes. Our area takes in Five Ash Down and its surroundings, with estates and business parks such as Ashdown Business Park included. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
