Mastic sealing in Rodmersham

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

Owners, agents and contractors

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

How we handle mastic sealing in Rodmersham

Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. Most enquiries involve draught complaints from residents or tenants and no planned programme for sealant, on shopfronts below residential blocks, external wall and movement joints and balcony and threshold joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Rodmersham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In and around smaller places like Rodmersham, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Mastic sealing around Rodmersham: how the place shapes the job

The sea is no more than about 3 miles from Rodmersham. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.

If you own or manage units on a site such as Kent Science Park, which lies west of Rodmersham, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If your remit includes a building such as Rodmersham School, frame and door mastic can be programmed for the holidays.

Rodmersham is about 2 miles south-east of Sittingbourne, in Kent. Any commercial site in Rodmersham is covered, for single jobs and planned programmes alike. 931 places across Kent fall within our area, including Rodmersham. For work in that direction, see our London page, about 39 miles away.

How the job changes by surface

Window and door perimeters on blocks

On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.

Commercial and mixed-use buildings

Tenants in commercial buildings need to keep trading so the work is phased.

Cost factors for mastic joints

Quotes vary with the job. It mainly depends on:

  • Quantities, in metres or numbers
  • The product specified
  • Travel to remote or island sites
  • Phasing around occupants

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • The asbestos register, for older buildings
  • Specification clauses that apply
  • The postcode of the building
  • Any dates the work must fit around

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

Signs you need mastic sealing in Rodmersham

Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.

Look out for the following:

  • Damaged joints in communal entrances and corridors
  • Draughts at frames across a block
  • Complaints coming in block by block
  • Leaks at window and door perimeters

Trustees of buildings like Church of St Nicholas can bring frame and external mastic into a planned maintenance list.

  • Whether old or failed sealant will be cut out, not overlaid
  • Do they follow the manufacturer’s priming guidance?
  • How they’ll work around occupants

Our contractor checklist

How a job runs

Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If others near Rodmersham need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Let building users know which areas are affected
  • Have the specification and drawings to hand

Request a quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Advice

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Leaks through the frame itself rather than the perimeter
  • Glazing that needs replacing
  • Masonry that has broken away beside the joint

If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.

  • Shopfronts below residential blocks
  • Communal entrances and stairwells
  • Window and door perimeters on blocks
