When to call us in Tenterden

UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.

What tends to prompt an enquiry:

  • No planned programme for sealant
  • Window mastic that has split and shrunk
  • Worn sealant at communal door frames
  • Damp patches beside frames

Older buildings near Tenterden, from historic houses such as Smallhythe Place, 2.2 miles to the south of Tenterden, to more modest stock, need compatible products when frames are resealed.

Before you book anyone

  • Will CSCS-carded applicators be on site?
  • Their approach to joint depth and backing
  • Whether primer will be used where the manufacturer specifies it
  • How long is the guarantee, and what does it include?

Our contractor checklist

Mastic sealing in Tenterden, done properly

Across Tenterden and the rest of Kent, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. Most enquiries involve the same joint failures repeated across a portfolio and movement joints with sealant missing, across communal entrances and stairwells, window and door perimeters on blocks and shopfronts below residential blocks. A specialist sealant contractor works differently from a general builder: in Tenterden, that means joint design, primers and backing rod as standard.

Places the size of Tenterden normally have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.

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.

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work normally takes a few days for most blocks, with larger programmes scheduled building by building. Work in places the size of Tenterden is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  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 where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Before we start on site

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

What the job involves on each surface

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Tenement and older buildings

Natural stone can be marked by the wrong sealant and we choose accordingly.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Broken glass or failed sealed units
  • Leaks through the frame itself rather than the perimeter
  • Masonry that has broken away beside the joint

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Joints and surfaces we work on

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

Quoting for work in Tenterden

To price the job, we consider:

  • How much existing material needs removing
  • The total length or number of joints
  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • When you need the work done
  • What the building is and how it’s used
  • How the joints are reached, and at what height
  • Whether an asbestos survey exists

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Questions we are asked in Tenterden

Will you take on work at estates like Pickhill Business Centre, close to Tenterden?

Yes, sites like Pickhill Business Centre are within our area, along with the rest of Tenterden. A few photographs and the unit address let us price the work.

Do you take on block-wide or estate-wide mastic work in Tenterden?

Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.

How long does a job like this take?

Do you check for asbestos in old sealant?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.

How do you handle work on occupied blocks?

Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.

Do you guarantee the mastic work?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.

Block-wide mastic in Tenterden

Tenterden sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building normally need attention first. Central London is about 45 miles from Tenterden. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.

Older community buildings, Parish Church of St Mildred among them, often have frames of mixed ages whose mastic varies. If your remit includes a building such as Tenterden Infant School, frame and door mastic can be programmed for the holidays.
