Sealant applicators in Chitty

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, run the same way on every site: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Chitty, phone 01277 525 020 or email us with the site addresses. We work on kitchen worktops and splashbacks, external facade joints and window and door perimeters, and the usual reasons a site gets in touch are messy, uneven beads from earlier work that let the building down and a top-up bead over failed sealant, now lifting. For commercial sealant work in Chitty, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In Chitty, as anywhere, the first joints to go are usually the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Business units in the countryside around places like Chitty are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

FAQs: Chitty

Is a smaller place like Chitty outside your area?

Not at all. Chitty is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Our building in Chitty is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Is the old sealant taken out first?

Full removal is part of every quote. Sealing over traps water and lifts once the joint moves.

Can you take on work for an FM or managing agent?

Yes. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.

Can areas stay open during the work?

It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Different surfaces, different methods

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Chitty, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. You send photographs, drawings or a list of the joints and areas involved.
  2. Next comes a diagnosis and a fixed quote.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Send your site hours and access windows

Working on commercial sites near Chitty

Chitty lies within about 3 miles of the sea. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. A matched colour is only half the brief on an exposed frontage. Chitty is about 57 miles from central London. The commuter belt holds a great many offices, retail parks and business parks. Firms with branches across the South East can use one contractor for every site.

If you have premises on more than one site, say at Chislet Business Park and Canterbury Industrial Park, one contractor and one quote can cover both. For tenants and agents on sites such as Chislet Business Park, which lies south-west of Chitty, office fit-outs, reception joints and window perimeters are the usual sealant work.

Chitty is about 4 miles south-east of Herne Bay, in Kent. Anywhere in CT3, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Kent coverage takes in 931 places. For work in that direction, see our London page.

Commercial sites across CT3 are covered for sealant joints. If your building is just outside Chitty, we cover Chislet (1 mile west), Hollow Street (1 mile south-west), Boyden Gate (1 mile north-west), Old Tree (1 mile west) and Highstead (1 mile north-west). Further afield, our area takes in Canterbury (7 miles south-west), Margate (9 miles east), Dover (14 miles south), Ramsgate (9 miles east), Broadstairs (10 miles east) and Whitstable (7 miles west).

Near you in Chitty

We work on buildings around Grove Ferry Picnic Area, among other places. The nearest railway station is Herne Bay station, about 4 miles north-west. A little further out are St Martins Hospital (5.8 miles south-west). Green spaces nearby include West Blean and Thornden Woods.

Commercial clients in Chitty

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Whether you are 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. We can agree access arrangements and keyholder contacts beforehand.

Do you need commercial sealant contractors in Chitty?

Resealing over the top is a false economy we come across often. New silicone has nothing to key into. Getting back to a clean joint then means removing every layer.

Typical triggers for a call:

  • A top-up bead over failed sealant, now lifting
  • Untidy joints in a reception, shop floor or lobby
  • Expansion joints with the sealant torn out
  • Weathered facade sealant that no longer flexes

Offices and shops close to stations such as Herne Bay station (to the north-west of Chitty) tend to be busy all day, so sealant work is planned around opening hours.

What your quote should include

  • Whether their applicators hold CSCS cards
  • How joint depth will be controlled
  • Whether primer will be used where the manufacturer specifies it
  • Health and safety accreditation such as CHAS

How to choose a sealant contractor

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. 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.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Honest limits

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Water from a services leak rather than a joint
  • Misted, cracked or failed glazing units (a glazier’s job)

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