Mastic sealing in Charing

For blocks and buildings in Charing and across Kent, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on window and door perimeters on blocks, shopfronts below residential blocks and balcony and threshold joints, and the usual reasons a site gets in touch are window mastic that has split and shrunk and complaints coming in block by block. Looking for mastic applicators who cover Charing? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

In a smaller place such as Charing, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

When to call us in Charing

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.

Clients normally get in touch after noticing something like this:

  • Damaged joints in communal entrances and corridors
  • Draught complaints from residents or tenants
  • No planned programme for sealant
  • Damp patches beside frames

Churches, halls and community buildings such as Church of St Peter and St Paul are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Questions to ask before you book

  • Who will actually carry out the work
  • Their public liability cover
  • Can the work be phased to keep areas open?
  • Which product they’ll use, and why it suits the joint

Block-wide mastic in Charing

At about 43 miles from central London, Charing is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

Blocks of flats and mixed-use buildings often cluster around stations such as Charing station, under half a mile to the south-west of Charing, and their window and balcony mastic tends to age at the same rate across a building. Schools and community buildings such as Charing Church of England Primary School need frame and external mastic kept sound like any building.

Charing is about 6 miles north-west of Ashford, in Kent. If you are looking for mastic sealing in Charing, we can help, as we do across Kent. Charing is one of 931 places in Kent on our list for mastic joints. Our London page has more on work in that area, about 43 miles away.

Commercial sites across TN27 are covered. We cover commercial and managed buildings on The High Street, Market Place and Station Road and the roads nearby. We also cover Charing Heath (1 mile west), Cold Harbour (2 miles north-west), Lenham Heath (2 miles west), Stonebridge Green (2 miles west) and Lenham Forstal (3 miles west). Bigger towns within reach include Maidstone (12 miles west), Ashford (6 miles south-east), Canterbury (13 miles east), Sittingbourne (9 miles north), Whitstable (14 miles north-east) and Faversham (8 miles north-east).

Local landmarks in Charing

We work on buildings around Spuckles and Kennelling Woods and King's Head Public House and the streets around them. There’s a railway station in Charing itself: Charing station. Nearby you’ll also find Coldbridge Castle (4.3 miles west).

Keeping the joints sound

A few simple habits keep the new joints working:

  • Avoid piecemeal callouts where you can
  • Make mastic part of routine maintenance checks
  • List the paperwork your organisation requires when you send details
  • Log resealing dates block by block

Where a paintable product was specified, it can be painted after curing. Silicone normally can’t be painted, so keep decorators off it.

One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

When something else is needed

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Leaks through the frame itself rather than the perimeter
  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
  • Materials that need asbestos testing before work

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

Surfaces we seal

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

What affects the price in Charing

To price the job, we consider:

  • Whether the work must be split into stages
  • Removal of failed or old sealant
  • Which sealant the job calls for
  • Joint width, depth and condition

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What to include in your enquiry

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

  • Any specification or named product
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or use the quote form.

Questions about Charing

Is Charing too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you price a mastic programme across our Charing portfolio?

Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.

Will residents or tenants be disturbed?

We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.

Is mastic sealing guaranteed?

Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How do you reach windows on upper floors?

Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.

Site staff or a sealant specialist?

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.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

How a job runs

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For a site in Charing, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  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 your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
