Need facade sealing in Charing?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

When something else is needed

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Replacing glass or failed glazing units
  • Cracked or spalling substrates that need repair before sealing
  • Water getting in through cracked render or porous masonry

If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.

Surfaces we seal

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

About our facade sealing in Charing

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on window and door perimeters, cladding panel joints and perimeter joints where frames meet the structure, and what we’re called in for most is air leaks through failed facade joints and old perimeter mastic that has dried out. Whoever orders the work in Charing, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

For a contractor on a smaller site near Charing, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.

A 12-month guarantee applies to all our work in Kent. Should something we installed fail, give us a call on 01277 525 020 or send photos by email and we’ll come back to it.

Contractors’ notes for Charing

Central London is about 43 miles from Charing. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. 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.

With historic properties like Godinton House, 3.9 miles to the south-east of Charing, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Charing is about 6 miles north-west of Ashford, in Kent. Charing sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Kent coverage takes in 931 places, large and small. London is covered too, around 43 miles from Charing.

Our process

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Work in places the size of Charing is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We start with photographs, drawings or a visit to see the joints and agree 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. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot
  • Let us know about inductions and permits

Questions about Charing

Is Charing too small for you to travel to?

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

Will you fit the mastic around our build programme in Charing?

Yes. The mastic is planned around your key stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

What type of sealant goes on window perimeters?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Is your workmanship covered by a guarantee?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

Can you just add new sealant on top?

No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.

Should we check old sealant for asbestos?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.

How the job changes by surface

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, as the specification sets out.

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Maintenance after handover

Once the work is signed off, these steps help:

  • Check the asbestos register before old mastic is disturbed
  • Avoid harsh cleaners on facade sealant
  • Don’t wait for a second leak before calling
  • Keep the sealant details on the building file

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

Why act early in Charing

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. In a smaller place such as Charing, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why appoint us

  • 12-month guarantee on workmanship
  • Coloured sealants to suit the setting, where available
  • Joints cleaned back to sound surfaces
  • Commercial sealant work since 2005

Take a look at what affects the cost or our accreditations.

When to call us in Charing

Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.

Clients usually get in touch after noticing something like this:

  • Old perimeter mastic that has dried out
  • Leaks at window and door perimeters
  • Perimeter sealant that has split or peeled away
  • Air leaks through failed facade joints

School extensions, at buildings such as Charing Church of England Primary School, normally run to the summer holidays, mastic included.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Can the work be phased to keep areas open?
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
