Facade sealing in Elmstone, done properly

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, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. If you are dealing with sealant pulling away from frames or panels and air leaks through failed facade joints, we can put it right, whatever the surface. Most enquiries from Elmstone start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For a site near Elmstone, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When something else is needed

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Replacing glass or failed glazing units
  • Render or concrete edges that have broken away
  • Movement beyond what any sealant can handle

If you’re not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.

What we seal

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

Sites and facades in and around Elmstone

Central London is about 59 miles from Elmstone. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.

Units on estates such as Wingham Industrial Estate, 2.3 miles south-west of Elmstone, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Older buildings in the area around Elmstone, such as Goodnestone Park, 3.9 miles south of Elmstone, need care when sealed: the product has to suit soft or historic materials. On a healthcare site such as St Martins Hospital, 5.9 miles to the west of Elmstone, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Elmstone is about 7 miles south-east of Herne Bay, in Kent. Anywhere in CT3, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 931 places in Kent, from busy centres to rural villages. We also cover London, around 59 miles from Elmstone.

If you need facade sealing in CT3, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Streets here include Padbrook Lane, Sheerwater Road and Longmete Road.

From enquiry to sign-off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Elmstone are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot
  • Flag any permit to work we will need

Your questions answered

Does your area include sites such as Wingham Industrial Estate, near Elmstone?

Yes. Estates, retail parks and business parks around Elmstone, Wingham Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is a hospital such as St Martins Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

When can you be on site?

We are 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.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

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.

Different surfaces, different methods

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.

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, and mask the edges carefully.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • The product specified
  • How much existing material needs removing
  • Whether the work must be split into stages

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • The product your specification calls for
  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Any dates the work must fit around

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Owners, agents and contractors

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

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Doing it in-house

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
