Facade sealing for Ditton sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Facade sealing in Ditton, done properly

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. We work on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints, and the failures we’re asked to look at most are sealant pulling away from frames or panels and previous reseals run over old sealant. One point of contact handles commercial sealant work in Ditton from the first photos to the final walk-round, whether it’s one building or several.

On a small site around Ditton, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.

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’re upfront about that.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Damaged frames that need replacing
  • Providing access systems for the work

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Surfaces we seal

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

Questions we are asked in Ditton

Do you cover business parks and estates near Ditton, such as South Aylesford Retail Park?

Yes. Our area takes in Ditton and its surroundings, with estates and business parks such as South Aylesford Retail Park included. A few photos and the unit address let us price the work.

Is a hospital such as Maidstone Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Do you provide access for facade work?

That comes down to the access arranged for the job. When you ring 01277 525 020 or email a schedule or drawings, describe the access, and we will plan the work with you.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Can the sealant be colour-matched?

It depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Can you work to our specification?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Building and refurbishing in Ditton

Rainfall across the South East, Ditton included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Ditton lies roughly 28 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.

New wings at hospitals like Maidstone Hospital, 1.9 miles to the south-east of Ditton, bring long runs of window and panel joints to seal. Work at a hotel such as Hamlet Hotel Maidstone, 0.8 miles to the north-west of Ditton, tends to be programmed around bookings, mastic included.

Ditton is about 4 miles north-west of Maidstone, in Kent. Businesses, contractors and managing agents in Ditton use us for work on facade joints. Across Kent, 931 places are covered, including Ditton. There’s a separate page for London, about 28 miles away.

What we’re called out for in Ditton

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.

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

  • Patch repairs that keep failing
  • Damp patches beside frames after rain
  • Cold air coming in at window perimeters
  • Failed sealant on precast panel joints

Building work at universities like University for the Creative Arts - Maidstone (to the south-east of Ditton) is often timed for the summer, mastic included.

What to look for in a quote

  • Their approach to joint depth and backing
  • How the existing material will be dealt with
  • What level of public liability insurance do they hold?
  • What the guarantee covers, and for how long

Our contractor checklist

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. Small buildings around Ditton suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • A Constructionline member, so easy to vet
  • Work carried out by CSCS-carded applicators
  • Fully insured
  • Specification-led, product-correct work

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Avoid harsh cleaners on facade sealant
  • Don’t wait for a second leak before calling
  • Avoid patch repairs on failed facade joints
  • Share access with other external trades

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.

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.

Diagnose, treat, sign off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a site in Ditton, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  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. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Let us know about inductions and permits
  • Point out parking and an unloading spot
  • Tell staff and tenants when we will be in

Should maintenance staff do it?

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.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
