Facade sealing in Bossingham

Facade sealants sit in the sun, rain and frost every day. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. If you have weathered joints at frame-to-structure perimeters and gaps between rainscreen or cladding panels, we can put it right, on coping and flashing joints, stone and brick facade joints and window and door perimeters alike. Searching for sealant specialists in Bossingham? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Around smaller places like Bossingham, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. 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. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Inspect facade joints on a regular cycle
  • Insist on a full cut-out when joints are renewed
  • Record the product and colour used on each elevation
  • Check that rainwater leaves the facade the way it was designed to

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly with a compatible product.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Render or concrete edges that have broken away
  • Arranging specialist high-level access, which is planned with the client
  • Water getting in through cracked render or porous masonry

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Mastic packages on Bossingham sites

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 the external programme keeps a little slack. Bossingham lies roughly 55 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.

With historic properties like Acrise Place, 4.9 miles to the south-east of Bossingham, in the area, refurbishment work often meets old masonry that needs compatible sealants. For a contractor working at a hospital such as Kent and Canterbury Hospital, 4.7 miles to the north of Bossingham, perimeter and facade sealing is planned around patients and deliveries.

Bossingham is about 6 miles south of Canterbury, in Kent. Commercial clients in Bossingham use us for work on facade joints. Across Kent, 931 places are covered, including Bossingham. We also cover London, around 55 miles from Bossingham.

We cover the CT4 postcode districts. For a building on The Street, Bossingham Street and Manns Hill or nearby, send details and we will quote for facade joints. Nearby places we also cover include Stelling Minnis (1 mile south-west), Waltham (2 miles west), Rhodes Minnis (4 miles south), Stowting Common (4 miles south-west) and Ottinge (4 miles south) for facade joints. A short drive away, we cover Ashford (10 miles south-west), Canterbury (6 miles north), Dover (10 miles south-east), Folkestone (9 miles south-east), Whitstable (11 miles north) and Deal (14 miles east).

How the job changes by surface

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first.

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Bossingham may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  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. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Let us know about inductions and permits
  • Send your site hours and access windows

What we are called out for in Bossingham

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building.

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

  • Gaps between rainscreen or cladding panels
  • Failed seals around shopfront and entrance frames
  • Weathered facade joints that have lost their grip
  • Unsightly perimeter sealant on a visible elevation

School extensions, at buildings such as Stelling Minnis Church of England Primary School, usually run to the summer holidays, mastic included.

How to choose a sealant contractor

Questions we’re asked in Bossingham

Can the mastic package for our job in Bossingham follow the site programme?

Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is a smaller place like Bossingham outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What hours do you work?

Mention the site’s hours and 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.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
