Facade sealing for businesses in Robertsbridge

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Site staff or a sealant specialist?

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.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

About our facade sealing in Robertsbridge

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. Site teams most often ask us about leaks at window and door perimeters and perimeter joints where frames meet the structure, across stone and brick facade joints, coping and flashing joints and perimeter joints where frames meet the structure. A single leaking joint is often how a building in Robertsbridge first comes to us: we look at the rest while we are there and tell you what we find.

Conversions of older rural buildings near smaller places such as Robertsbridge 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.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Building owners, agents and FMs in Robertsbridge

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Your questions answered

Can you take on a job at a hospital such as Ticehurst House Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Vinehall Business Centre, near Robertsbridge?

Yes. Our area takes in Robertsbridge and its surroundings, with estates and business parks such as Vinehall Business Centre included. A few photos and the unit address let us price the work.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Is old mastic on our building likely to contain asbestos?

For older buildings, yes, check before work starts. 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.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions.

Which sealant will you use?

A specification, where there is one, decides it. 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.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

When to call us in Robertsbridge

Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

It’s worth sending us details if you spot any of the following:

  • Leaks at window and door perimeters
  • Discoloured or dirty facade joints
  • Cold air coming in at window perimeters
  • Old perimeter mastic that has dried out

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

What your quote should include

  • Will failed sealant be removed rather than covered?
  • The terms of the workmanship guarantee
  • Health and safety accreditation such as CHAS
  • How they handle RAMS and site documents

How to choose a sealant contractor

Sites and facades in and around Robertsbridge

Robertsbridge is in the South East, one of the UK’s drier regions. 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. Robertsbridge is about 43 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

Recladding or extending a unit at a site like Vinehall Business Centre, 2.5 miles to the south-east of Robertsbridge, brings panel joints and frame perimeters into the programme. Historic houses such as Durhamford Manor (to the south-east of Robertsbridge) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Robertsbridge is about 9 miles north-west of Hastings, in East Sussex. We send applicators to Robertsbridge for facade joints. Our East Sussex coverage takes in 308 places. For work in that direction, see our Brighton page (28 miles or so).

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Smaller jobs around Robertsbridge can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  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. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Let building users know which areas are affected

Why act early in Robertsbridge

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts. Halls, stores and units around places like Robertsbridge may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why appoint us

  • One number for every site we cover
  • Commercial sealant work since 2005
  • Fully insured
  • Constructionline member for supplier checks

Read what affects the cost or our accreditations.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Report water ingress at frames as soon as it shows
  • Clear debris that holds water against joints
  • Avoid harsh cleaners on facade sealant
  • Check the asbestos register before old mastic is disturbed

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones behind the facade.
