About our construction mastic in Breeds

The specification and the programme set the job, not to habit. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out, so the joints perform as the designer intended. If you’re dealing with a mastic package split between trades with no clear owner and new external sealant already peeling away, we can put it right, whatever the surface. Most enquiries from Breeds 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 Breeds, 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, photos and the programme let us give a fixed quote.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

From enquiry to sign-off

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Breeds can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We start with the drawings, specification and programme.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Joints are prepared, backed and sealed to the specification.
  6. After snagging, the work is handed over under our 12-month guarantee.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification
  • Tell us what induction or permit system the site runs

How the job changes by surface

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 while moving joints need a flexible sealant.

Bathrooms, en suites and washrooms

Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.

Looking after the joints

After handover, a little attention goes a long way:

  • Plan external elevations with the weather in mind
  • Don’t schedule sealing before decorators and flooring are done
  • Get the mastic subcontractor involved early in the programme
  • Flag uneven or tapered frame gaps early

At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. We can confirm the handover information you need when we quote.

One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating, and a delay to handover. Checking perimeters before internal finishes go on avoids it.

Construction mastic around Breeds: what changes locally

Breeds sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. Breeds is about 31 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

When units on a site such as Regiment Business Park, 1.9 miles to the south-east of Breeds, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Projects at schools like Chelmer Valley High School work to term dates, so mastic is programmed tightly. New wings at hospitals like Broomfield Hospital (to the south-east of Breeds) bring long runs of window and panel joints to seal.

Breeds is about 4 miles north of Chelmsford, in Essex. Looking for construction mastic in Breeds? We can help. Breeds is one of 644 places we cover in Essex. For work in that direction, see our London page.

Owners, agents and contractors

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Breeds can form part of a wider programme across Essex.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

When to bring in a specialist

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.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

What affects the price in Breeds

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

  • Induction, permit and paperwork requirements
  • How accessible the joints are
  • Backing rod, priming and other preparation
  • How much there is to seal

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height
  • Any dates the work must fit around
  • The product your specification calls for

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or use the quote form.

Breeds: questions and answers

Is Breeds too small for you to travel to?

Not at all. Breeds is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Is hospital work, at somewhere like Broomfield Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Do you guarantee new-build sealant work?

Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.

How long before the joints can be used?

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

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
