Questions about Ditchling

Is Ditchling too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you work around term dates at a campus such as University of Sussex?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do we need an asbestos check before resealing?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.

About our facade sealing in Ditchling

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. We work on shopfront frames, stone and brick facade joints and window and door perimeters, and the failures we are asked to look at most are damp patches beside frames after rain and draughts around frames and panels. Whether you call it commercial sealant work, mastic application or joint sealing, in Ditchling it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Ditchling, 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.

Our workmanship is guaranteed for 12 months, in Ditchling as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Do you need facade sealing in Ditchling?

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.

Typical triggers for a call:

  • New sealant peeling off old mastic
  • Staining on stone next to old sealant
  • Failed seals around shopfront and entrance frames
  • Draughts around frames and panels

When a college such as Plumpton College (to the south-east of Ditchling) builds or refurbishes, the mastic package typically has to fit around students and staff.

What your quote should include

  • Their public liability cover
  • How the joint faces will be prepared and primed
  • How the existing material will be dealt with
  • The named product and why it was chosen

How to choose a sealant contractor

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Ditchling, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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

  • Tell us which areas need to stay in use
  • Send any specification or drawings in advance
  • Tell staff and tenants when we’ll be in

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Keep sills, gutters and drainage paths clear
  • Keep the sealant details on the building file
  • Avoid patch repairs on failed facade joints
  • Avoid harsh cleaners on facade sealant

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.

Facades, frames and programmes in Ditchling

Ditchling sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. At about 40 miles from central London, Ditchling is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

Hospital estates such as The Dene Hospital, 3.8 miles to the north-west of Ditchling, 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. Units on estates such as Ditchling Common Business Park, 2 miles to the north-east of Ditchling, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Ditchling is about 3 miles south of Burgess Hill, in East Sussex. Across the BN6 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 308 places across East Sussex fall within our area, including Ditchling.

Commercial clients in Ditchling

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.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints too narrow for the movement they take, which need redesign
  • Work on the window or framing system itself

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think.
