Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Mastic sealing for commercial buildings in Chilham

For blocks and buildings in Chilham 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, and site visits can be arranged. We work on communal kitchens and washrooms, communal entrances and stairwells and balcony and threshold joints, and the usual reasons a site gets in touch are draughts at frames across a block and damp patches beside frames. One point of contact handles commercial sealant work in Chilham from the first photographs to the final walk-round, whether it’s one building or several.

In and around smaller places like Chilham, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, call 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Water coming in from the roof or rainwater goods
  • Asbestos-containing sealant, which we don’t remove
  • Misted or failed double-glazed units

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.

Joints and surfaces we work on

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

Do you need mastic sealing in Chilham?

Occasionally the substrate fails, not the sealant for instance where render or brick edges crumble. We will tell you if the joint edges need repairing before resealing.

Look out for the following:

  • A mix of products and colours from past repairs
  • Damaged joints in communal entrances and corridors
  • No planned programme for sealant
  • Open joints in brickwork or panels

Blocks of flats and mixed-use buildings often cluster around stations such as Chilham station, less than half a mile east of Chilham, and their window and balcony mastic tends to age at the same rate across a building.

What your quote should include

  • How the joint faces will be prepared and primed
  • Health and safety accreditation such as CHAS
  • Will RAMS and insurance details be available?
  • Whether their applicators hold CSCS cards

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a day or two for a single block, longer for an estate programme, and we clear our waste as we work. Rural sites near Chilham may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Let us know about inductions and permits
  • Warn occupants and staff about the work

Ask for a quote

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or send photos by email.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Redoing a failed joint normally costs more than getting it right at the outset, 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.

Mastic sealing around Chilham: what changes locally

Central London is about 49 miles from Chilham. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Rainfall across the South East, Chilham included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.

For owners of several units at places like CMA Industrial Park, 2.8 miles north-east of Chilham, one programme can deal with frame and external mastic across the lot. Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Chilham is about 5 miles south-west of Canterbury, in Kent. Across the CT4 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 931 places in Kent. Our London page has more on work in that area, about 49 miles away.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Joint width, depth and condition
  • Distance, for remote addresses
  • The site’s rules and procedures
  • The product specified

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Any dates the work must fit around
  • The postcode of the building
  • A wide shot and a close-up of the area
  • How the joints are reached, and at what height

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or ring 01277 525 020 or email the details over to discuss it first.

Questions we’re asked in Chilham

Can you work at a site such as CMA Industrial Park, by Chilham?

Yes. Our area takes in Chilham and its surroundings, with estates and business parks such as CMA Industrial Park included. A few photographs and the unit address let us price the work.

Is Chilham off your patch?

No. Places such as Chilham are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

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

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

What guarantee do you give on resealing?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
