What happens if it’s left?

Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, but external and wet-area joints that already leak shouldn’t wait. Splitting the scope into now and later is often the sensible compromise. For buildings around smaller places like Chartham Hatch, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Commercial mastic work in Chartham Hatch

Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we’ll plan around them. That applies whether the building is an office, a shop, a hotel, a college or a care home. Most enquiries involve a top-up bead over failed sealant, now lifting and untidy joints in a reception, shop floor or lobby, on external facade joints, washrooms and tea points and floor and threshold joints. Looking for mastic applicators who cover Chartham Hatch? We’ve been sealing commercial buildings since 2005.

A lot of what we do in Chartham Hatch is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Rural business units near smaller places such as Chartham Hatch are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Site staff or a sealant specialist?

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Diagnose, treat, sign off

At the end of each section, 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 building around Chartham Hatch, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. A final walk-round, then the 12-month guarantee applies.

What we need from you

  • Let building users know which areas are affected
  • Send any specification or drawings in advance
  • Agree which areas must stay open

Common problems we fix in Chartham Hatch

External sealant takes a steady beating from the weather. Sunny elevations dry the surface out and exposed ones take driving rain. A hardened bead can’t follow the building any more.

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

  • External beads that have gone brittle and cracked
  • Black mould through washroom sealant that won’t clean off
  • Wall and floor joints that have lost their seal
  • A top-up bead over failed sealant, now lifting

For a hotel such as Howfield Manor Hotel, which lies south-east of Chartham Hatch, the colour of a joint at the bar or the bath matters to the look of the room.

Before you book anyone

  • Whether their applicators hold CSCS cards
  • Are they CHAS accredited or on Constructionline?
  • What level of public liability insurance do they hold?
  • How joint depth will be controlled

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Note dates and locations of sealant work for future planning
  • Keep washroom and kitchen extraction working
  • On pre-2000 buildings, share the asbestos information before work starts

We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.
