Mastic sealing around Chestfield: what changes locally

The sea is no more than about 1 mile from Chestfield. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. Chestfield has two care or nursing homes no more than 2 miles away. Care home owners need frame and external mastic kept sound without unsettling residents.

If your remit includes a building such as Swalecliffe Community Primary School, frame and door mastic can be programmed for the holidays. Trustees of buildings like Church of St John the Baptist can bring frame and external mastic into a planned maintenance list.

Chestfield is about 1 mile east of Whitstable, in Kent. We cover Chestfield and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Our Kent coverage takes in 931 places, large and small. For work in that direction, see our London page (51 miles or so).

Anyone looking for mastic sealing in CT5 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Mastic sealing in Chestfield

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Chestfield carry our 12-month guarantee. If you are dealing with damaged joints in communal entrances and corridors and estate-wide sealant that is simply worn out, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Chestfield is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For owners with a single building near Chestfield, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Failed window or door frames, which need a window contractor
  • Asbestos-containing sealant, which we don’t remove
  • Water coming in from the roof or rainwater goods

Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly.

Surfaces we seal

  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • Communal kitchens and washrooms
  • External wall and movement joints
  • Window and door perimeters on blocks
  • Balcony and threshold joints

Chestfield: questions and answers

Is Chestfield too far out for you?

No. Places such as Chestfield are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can you work in a care home near Chestfield with residents in?

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

Do you supply RAMS and insurance details?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

What will the job cost?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Common problems we fix in Chestfield

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Typical triggers for a call:

  • Mastic failing across several blocks on an estate
  • Failed external movement joints
  • Repeated reactive repairs to the same buildings
  • Old repairs sealed over failed mastic

Landlords with units on estates such as John Wilson Industrial Estate, less than half a mile west of Chestfield, can bring frame, door and external mastic across several units into one programme.

  • How the existing material will be dealt with
  • What site paperwork they can supply
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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.

What affects the price in Chestfield

Quotes vary with the job. Expect it to depend on:

  • The size and state of each joint
  • Location, for remote and island sites
  • Induction, permit and paperwork requirements
  • Any access equipment needed

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Before you send an enquiry

There’s no need for a formal survey. These details are enough to start:

  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available
  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height

For a fixed quote, ring 01277 525 020 or send details through our quote form with the site address and an outline of the work. You can also send details through our quote form.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around Chestfield can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Share your working hours and any access restrictions
  • Confirm the product named in the specification
