For managing agents and facilities managers

About our construction mastic in Sandhurst Cross

Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, with public liability insurance in place. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. Site teams most often ask us about perimeter gaps outside the sealant’s range and failed sealant in an existing building being refurbished, on cladding and panel joints, internal decorators’ caulk and sanitary and kitchen joints. Most enquiries from Sandhurst Cross start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

For a site near Sandhurst Cross, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Sandhurst Cross need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. Final snagging is completed and the 12-month guarantee applies.

What we need from you

  • Warn occupants and staff about the work
  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand

Common problems we fix in Sandhurst Cross

Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.

Most enquiries start with something like this:

  • Old sealant on a refurbishment that needs stripping before new work
  • Sealant knocked or painted over by other trades
  • New external sealant already peeling away
  • Frame perimeters left unsealed or poorly sealed

For contractors refurbishing units at places like Bodiam Business Park (1.8 miles south-west of Sandhurst Cross), the mastic covers cladding panels, roller-door and window perimeters.

Facades, frames and programmes in Sandhurst Cross

Sandhurst Cross lies roughly 43 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme. Sandhurst Cross is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

New wings at hospitals like Benenden Hospital, 5.4 miles north-east of Sandhurst Cross, bring long runs of window and panel joints to seal. Older buildings in the area around Sandhurst Cross, such as Great Dixter, 2.5 miles south-east of Sandhurst Cross, need care when sealed: the product has to suit soft or historic materials.

Sandhurst Cross is about 11 miles north of Hastings, in Kent. Across the TN18 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Cost factors for mastic packages

A fixed quote reflects the actual work. It allows for:

  • How much there is to seal
  • Site requirements such as inductions and permits
  • Specialist products, such as fire-rated or hygienic sealants
  • Location, for remote and island sites

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • Access details, including height
  • Any dates the work must fit around
  • Approximate linear metres or a joint schedule
  • What the building is and how it’s used

For a fixed quote, call the office on 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. Our quote form is another easy route.

Different surfaces, different methods

Internal decorators’ caulk

Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted.

Snagging before handover

Snags typically come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately, depending on what suits the programme.

Questions about Sandhurst Cross

Do you take on work at healthcare sites like Benenden Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Bodiam Business Park, near Sandhurst Cross?

Yes, sites like Bodiam Business Park are within our area, along with the rest of Sandhurst Cross. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Can you come in just for snagging?

Yes. We can work through a mastic snag list area by area before handover and damaged joints are redone properly.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
