Your questions answered

Will you take on work at estates like Millbrook Industrial Estate, close to Rotherfield?

Yes, sites like Millbrook Industrial Estate are within our area, along with the rest of Rotherfield. Photos and a short description are enough for a first look.

Is Rotherfield too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

How long does a job like this take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do you replace failed glazing units?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How we handle facade sealing in Rotherfield

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. We work on cladding panel joints, shopfront frames and coping and flashing joints, and the failures we are asked to look at most are failed seals around shopfront and entrance frames and old perimeter mastic that has dried out. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Rotherfield is the same: the right product in a properly prepared joint.

Conversions of older rural buildings near smaller places such as Rotherfield bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Common problems we fix in Rotherfield

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

Common reasons buildings call us in:

  • Damp patches beside frames after rain
  • Patch repairs that keep failing
  • Perimeter sealant that has split or peeled away
  • Perimeter joints where frames meet the structure

When a school such as Rotherfield Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Choosing a commercial sealant contractor

Quoting for work in Rotherfield

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Travel to remote or island sites
  • The size and state of each joint
  • How accessible the joints are
  • Phasing around occupants

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you’re ready.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • Any dates the work must fit around
  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product
  • Clear photographs of the problem areas

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or email drawings and photos with what you know.

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Rotherfield need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • Make sure the joints can be reached
  • Point out parking and an unloading spot
  • Send any specification or drawings in advance

Request a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

What we can’t put right

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Work on the window or framing system itself
  • Render or concrete edges that have broken away
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Where we work in Rotherfield

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

Facades, frames and programmes in Rotherfield

Rotherfield sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Rotherfield lies roughly 34 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

Units on estates such as Millbrook Industrial Estate, 1.1 miles to the west of Rotherfield, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For a contractor working at a hospital such as Crowborough War Memorial Hospital, 2.7 miles west of Rotherfield, perimeter and facade sealing is planned around patients and deliveries.

Rotherfield is about 2 miles east of Crowborough, in East Sussex. Anywhere in TN6, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 308 places across East Sussex fall within our area, including Rotherfield. Brighton is covered too, some 21 miles away.

We take on facade joints across the TN6 postcode area. We cover commercial and managed buildings on Church Road, Station Road and Church Walk and the roads nearby. If your building is just outside Rotherfield, we cover High Cross (1 mile south-east), Town Row (1 mile north-east), Argos Hill (1 mile south-east), Mark Cross (2 miles north-east) and Woolbridge (2 miles south-east). Nearby towns on our patch include Lewes (15 miles south-west), Hailsham (13 miles south), Uckfield (7 miles south-west), South Malling (15 miles south-west), Heathfield (6 miles south) and Southover (15 miles south-west).

Why act early in Rotherfield

Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. One visit to deal with every failing joint makes more sense than several trips to a place like Rotherfield, rather than one at a time. Send photographs of each area and we will quote for the lot.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
