Mastic sealing for commercial buildings in Ulcombe

For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you have old repairs sealed over failed mastic and draught complaints from residents or tenants, we can put it right, on window and door perimeters on blocks, balcony and threshold joints and shopfronts below residential blocks alike. A single leaking joint is often how a building in Ulcombe first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Ulcombe, 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What we’re called out for in Ulcombe

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.

These are often picked up first by site or facilities staff:

  • The same joint failures repeated across a portfolio
  • Repeated reactive repairs to the same buildings
  • Cracked, hardened mastic round windows on a block
  • Damp patches beside frames

If you are responsible for a building such as All Saints Church, frame and door mastic needs the same attention as any other property.

What your quote should include

  • Who will actually carry out the work
  • Their approach to joint depth and backing
  • The named product and why it was chosen
  • Their pre-qualification and accreditations

Our contractor checklist

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Ulcombe, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

What we need from you

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Getting a fixed quote

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Leave it or put it right?

Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. One visit to deal with every failing joint makes more sense than several trips to a place like Ulcombe, rather than one at a time. Photos of every joint help us quote for the whole job.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Block-wide mastic in Ulcombe

Ulcombe lies roughly 37 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. Ulcombe sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building usually need attention first.

Student blocks close to universities like Canterbury Christ Church University (4 miles north of Ulcombe) are easiest to work on between tenancies.

Cost factors for mastic joints

What shapes the price:

  • Quantities, in metres or numbers
  • How accessible the joints are
  • Which sealant the job calls for
  • Travel to remote or island sites

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • Approximate linear metres or a joint schedule
  • Clear photos of the problem areas
  • Specification clauses that apply
  • Where the site is, with the postcode

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email the details over.

Questions about Ulcombe

Do you work for managing agents with blocks near Harrietsham station?

Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.

Is Ulcombe too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

What guarantee do you give on resealing?

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

Can you send RAMS and CSCS details before starting?

Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

How do you handle work on occupied blocks?

We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.
