Facade sealing for Chislet sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Facade sealing in Chislet, 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. We work on shopfront frames, cladding panel joints and stone and brick facade joints, and the usual reasons a site gets in touch are patch repairs that keep failing and cladding panel joints that have opened up. Whoever orders the work in Chislet, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

In the countryside around places like Chislet, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or use the quote form and we will come back to it.

Work for main contractors and building owners

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Chislet can form part of a wider programme across Kent.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

What sets the cost

These are the things that shape the price:

  • Removal of failed or old sealant
  • Location, for remote and island sites
  • Joint width, depth and condition
  • Whether the work must be split into stages

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Any dates the work must fit around
  • The postcode of the building
  • Clear photographs of the problem areas
  • Specification clauses that apply

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or send details through our quote form.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Specialist high-level access methods
  • Movement beyond what any sealant can handle
  • Damaged frames that need replacing

If you’re not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Where we work in Chislet

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

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Combine resealing with other works that need access
  • Avoid patch repairs on failed facade joints
  • Inspect facade joints on a regular cycle
  • Check that rainwater leaves the facade the way it was designed to

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

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

Your questions answered

Is a smaller place like Chislet outside your area?

No. Places such as Chislet are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on work at estates like Chislet Business Park, close to Chislet?

Yes. We cover Chislet and the area around it, including industrial estates, business parks and retail parks such as Chislet Business Park. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

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.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

What type of sealant goes on window perimeters?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Can you find out why a window is leaking?

Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Mastic packages on Chislet sites

With the shore within about 3 miles, Chislet counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. At about 57 miles from central London, Chislet is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.

New units and refits on sites such as Chislet Business Park (to the south-west of Chislet) need their panel and perimeter joints sealed to the specification. New wings at hospitals like Queen Victoria Memorial Hospital (to the north-west of Chislet) bring long runs of window and panel joints to seal. For contractors at a school such as Chislet Church of England Primary School, sealing has to be finished before term starts.

Chislet is about 3 miles south-east of Herne Bay, in Kent. Across the CT3 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 931 places in Kent. We also cover London, some 57 miles away.

Postcode districts covered here: CT3. We also cover Hollow Street (1 mile south-west), Chitty (1 mile east), Boyden Gate (1 mile north), Old Tree (1 mile west) and Hoath (1 mile west) for facade joints. Bigger towns within reach include Canterbury (6 miles south-west), Margate (9 miles east), Dover (14 miles south), Ramsgate (10 miles east), Broadstairs (10 miles east) and Whitstable (7 miles west).

Landmarks near Chislet

We work on buildings around Grove Ferry Picnic Area and the streets around them. The nearest railway station is Herne Bay station, about 3.7 miles north-west of the centre. Well-known places in the area include St Martins Hospital (5.5 miles south-west). Open spaces near Chislet include West Blean and Thornden Woods.

From enquiry to sign-off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. For work around Chislet, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  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.

What we need from you

  • Arrange parking or a loading space
  • Make sure the joints can be reached
  • Let us know about inductions and permits

Related advice

What happens if it’s left?

Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. One visit to deal with every failing joint makes more sense than several trips to a place like Chislet, rather than one at a time. Send photos of each area and we’ll quote for the lot.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
