Facade sealing near Bapchild

Facade sealing in Bapchild

External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. 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 new sealant peeling off old mastic and draughts around frames and panels, we can help, on stone and brick facade joints, window and door perimeters and perimeter joints where frames meet the structure alike. A specialist sealant contractor works differently from a general builder: in Bapchild, that means joint design, primers and backing rod as standard.

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

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Never let anyone seal over old sealant
  • Ask about asbestos in pre-2000 mastic
  • Note when each elevation was last resealed
  • Clear debris that holds water against joints

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking anything from a single day to several weeks, depending on joint lengths, access and the weather. If others near Bapchild need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work

Questions about Bapchild

Can you work at a site such as Kent Science Park, by Bapchild?

Yes. Estates, retail parks and business parks around Bapchild, Kent Science Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can work at a site such as KITE College fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you replace failed glazing units?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

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.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

What will the job cost?

Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or email the details over.

Do you cover Bapchild?

Yes. Bapchild is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or use the quote form.

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Damp caused by condensation inside the building
  • Specialist high-level access methods
  • Joints whose design needs changing by the specifier

If you’re not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

Different surfaces, different methods

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint, not the framing or glazing itself.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.

Why deal with it now?

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once. Converted and older buildings near places like Bapchild tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Facades, frames and programmes in Bapchild

Bapchild lies roughly 39 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Bapchild sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

Hotels like Hempstead House Hotel, 1.2 miles to the north of Bapchild, rarely close for long, so refurbishment mastic is phased floor by floor. For contractors refurbishing units at places like Kent Science Park, which lies west of Bapchild, the mastic covers cladding panels, roller-door and window perimeters. For a contractor working at a hospital such as Sittingbourne Memorial Hospital, which lies north-west of Bapchild, perimeter and facade sealing is planned around patients and deliveries.

Bapchild is about 2 miles south-east of Sittingbourne, in Kent. We cover commercial sites throughout Bapchild, for single jobs and planned programmes alike. Bapchild is one of 931 places in Kent on our list for facade joints. Sites around London have their own page, about 39 miles away.
