Facade sealing in Doddington

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. The enquiries we see most involve weathered joints at frame-to-structure perimeters and facade joints cracked through the middle, on coping and flashing joints, perimeter joints where frames meet the structure and cladding panel joints. Whoever orders the work in Doddington, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Construction in and around smaller places such as Doddington is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Doddington need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Confirm the product named in the specification
  • Make sure the joints can be reached
  • For older buildings, check the asbestos register before work

Sites and facades in and around Doddington

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. At about 40 miles from central London, Doddington is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

When units on a site such as Kent Science Park, 3 miles to the north-west of Doddington, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. With historic properties like Belmont House and Gardens (3.3 miles east of Doddington) in the area, refurbishment work often meets old masonry that needs compatible sealants. University estates such as Canterbury Christ Church University (4.1 miles west of Doddington) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Doddington is about 5 miles south of Sittingbourne, in Kent. Any commercial site in Doddington is covered, for single jobs and planned programmes alike. Doddington is one of 931 places we cover in Kent. London is covered too, some 40 miles away.

Business premises anywhere in ME9 are within our area for facade joints. If your site is on The Street, Old Lenham Road and Northdown or close by, we can quote for facade joints. If your building is just outside Doddington, we cover Wichling (1 mile south-west), Bluetown (1 mile north-west), Newnham (1 mile east), Hollybushes (1 mile west) and Payden Street (2 miles south-west). Bigger towns within reach include Maidstone (11 miles west), Ashford (11 miles south-east), Canterbury (13 miles east), Sittingbourne (5 miles north), Whitstable (12 miles north-east) and Faversham (6 miles north-east).

Leave it or put it right?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Converted and older buildings near places like Doddington tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Surface by surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface.

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod.

Questions about Doddington

Do you cover business parks and estates near Doddington, such as Kent Science Park?

Yes. We cover Doddington and the area around it, including industrial estates, business parks and retail parks such as Kent Science Park. Send details of the unit and the work through our quote form for a quick quote.

Is Doddington too small for you to travel to?

No. Places such as Doddington are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

When is resealing likely to be due?

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

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we will set out a timescale with the quote.

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. We don’t remove asbestos-containing materials.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Check the asbestos register before old mastic is disturbed
  • Insist on a full cut-out when joints are renewed
  • Add perimeter sealant to planned maintenance checks
  • Combine resealing with other works that need access

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
