About our construction mastic in Cooling

The specification and the programme set the job rather than whatever product is to hand. Where the specification names a product, we use it; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. If you have oversized or tapered gaps around new frames and new external sealant already peeling away, we can help, on brick and block movement joints, cladding and panel joints and floor and skirting junctions alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Cooling it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Conversions of older rural buildings near smaller places such as Cooling bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Sites and facades in and around Cooling

Cooling lies within about 3 miles of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. Cooling is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

Hospital estates such as French Hospital, 4.8 miles south of Cooling, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Older buildings in the area around Cooling, such as Restoration House, 4.9 miles to the south of Cooling, need care when sealed: the product has to suit soft or historic materials.

Cooling is about 5 miles north of Rochester, in Medway. Businesses, contractors and managing agents in Cooling can call on us for mastic packages, as part of our coverage of Medway. Across Medway, 54 places are covered, including Cooling. London is covered too, some 27 miles away.

Quoting for work in Cooling

Before we quote, we look at:

  • The product specified
  • How accessible the joints are
  • How much there is to seal
  • Site requirements such as inductions and permits

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

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • Any dates the work must fit around
  • Specification clauses that apply

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or use the quote form.

Why deal with it now?

A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects. Where an alternative is genuinely suitable, we will say so. Converted and older buildings near places like Cooling tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

A quote for mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.

Why appoint us

  • A range of standard colours, depending on the product
  • A fixed quote before work starts
  • CSCS-carded applicators
  • One number for every site we cover

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Rural sites near Cooling may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. Final snagging is completed and the 12-month guarantee applies.

Preparing the site

  • Have the specification and drawings to hand
  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work

Cooling: questions and answers

Our building in Cooling is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

Is Cooling too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

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 the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What site paperwork can you supply?

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

How long does a job like this take?

That varies with the scale of the job, though a typical visit typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. For bigger or phased jobs, we’ll set out a timescale with the quote.

Signs you need construction mastic in Cooling

On construction sites, joints normally fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.

Typical triggers for a call:

  • Frame perimeters left unsealed or poorly sealed
  • Different trades sealing to different standards
  • Sanitary sealant damaged by following trades
  • Internal caulk splitting as the building dries out

On a campus such as University of Greenwich - Medway, 4 miles south of Cooling, new teaching buildings and residences are usually built and refurbished around the academic year.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Do they follow the manufacturer’s priming guidance?
  • What level of public liability insurance do they hold?

Choosing a commercial sealant contractor

Doing it in-house

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

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.
