Facade sealing near Chartham

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Your questions answered

Is Chartham too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will you plan work around the academic year at somewhere like University of the Creative Arts?

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.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Will rain stop the work?

Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

What do you charge?

Every job gets its own fixed quote. To get one, call 01277 525 020 or email the details over with a description of the work.

What’s the quickest route to a quote?

Facade sealing in Chartham, done properly

External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. If you are dealing with water coming in around window frames and old perimeter mastic that has dried out, we can put it right. Looking for mastic applicators who cover Chartham? We have been sealing commercial buildings since 2005.

Around smaller places like Chartham, 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.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

When to call us in Chartham

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back.

Clients typically get in touch after noticing something like this:

  • Weathered facade joints that have lost their grip
  • Discoloured or dirty facade joints
  • Perimeter sealant that has split or peeled away
  • Air leaks through failed facade joints

New units and refits on sites such as Stour Valley Business Park, 0.7 miles to the north-east of Chartham, need their panel and perimeter joints sealed to the specification.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?
  • How the existing material will be dealt with

Questions to ask before you appoint anyone

Different surfaces, different methods

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.

From enquiry to sign-off

Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around Chartham, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Flag any permit to work we will need
  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements

What happens if it’s left?

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Converted and older buildings near places like Chartham tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Facade sealing in Chartham: the local picture

Rainfall across the South East, Chartham included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Chartham is about 51 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

Work at a hotel such as Howfield Manor Hotel, 0.9 miles north-east of Chartham, tends to be programmed around bookings, mastic included. Projects at schools like Chartham Primary School work to term dates, so mastic is programmed tightly.
