About our facade sealing in Highsted

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. If you have leaks at window and door perimeters and old perimeter mastic that has dried out, we can help, whatever the surface. A single leaking joint is often how a building in Highsted first comes to us: we look at the rest while we’re there and tell you what we find.

Around smaller places like Highsted, building work normally 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.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Questions we’re asked in Highsted

Is Highsted too small for you to travel to?

Not at all. Highsted is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work around term dates at a campus such as Canterbury Christ Church University?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you provide access for facade work?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we will plan the work with you.

How long does a job like this take?

It depends on the scope, though a typical visit usually 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’ll set out a timescale with the quote.

Do you offer coloured sealant?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure.

How do we ask for a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Water getting in through cracked render or porous masonry
  • Cracked or spalling substrates that need repair before sealing
  • Movement beyond what any sealant can handle

If you are not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Leave it or put it right?

Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. One visit to deal with every failing joint makes more sense than several trips to a place like Highsted. Photos of every joint help us quote for the whole job.

Pricing facade joints depends on how many there are, their condition and the access. Call for a quote.

Why us?

  • Colours chosen to suit frames, cladding or finishes where possible
  • A range of standard colours, depending on the product
  • Workmanship guaranteed for 12 months
  • Fully insured, including public liability cover

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, 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. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Different surfaces, different methods

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch as the frame moves.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Brief window cleaners about newly sealed joints
  • Combine resealing with other works that need access
  • Confirm the survey covers external sealants in older buildings
  • Don’t wait for a second leak before calling

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.

Facade sealing around Highsted: what changes locally

Highsted is about 38 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. There are a number of hotels within about 2 miles of Highsted. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

On a campus such as Canterbury Christ Church University (4.5 miles south-west of Highsted), new teaching buildings and residences are usually built and refurbished around the academic year. On a healthcare site such as Sittingbourne Memorial Hospital, 1.1 miles to the north of Highsted, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Hotels like The George Hotel (to the north of Highsted) rarely close for long, so refurbishment mastic is phased floor by floor.

Highsted is about 2 miles south of Sittingbourne, in Kent. If you’re looking for facade sealing in Highsted, we can help. Highsted is one of 931 places in Kent on our list for facade joints. There’s a separate page for London, about 38 miles away.

Diagnose, treat, 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 a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. For work around Highsted, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  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. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Warn occupants and staff about the work
  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
