About our construction mastic in Wainscott

Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Site teams most often ask us about internal caulk splitting as the building dries out and different trades sealing to different standards, across brick and block movement joints, internal decorators’ caulk and window and door perimeters. Most enquiries from Wainscott 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.

On a small site around Wainscott, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.

Our workmanship is guaranteed for 12 months, in Wainscott as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Specifying the product where the designer hasn’t
  • Frames fitted out of tolerance
  • Faulty frames rather than failed sealant

If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think.

Joints and surfaces we work on

  • Floor and skirting junctions
  • Cladding and panel joints
  • Brick and block movement joints
  • Window and door perimeters
  • Sanitary and kitchen joints
  • Internal decorators’ caulk

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Get the mastic subcontractor involved early in the programme
  • Protect sealed areas from following trades
  • Flag uneven or tapered frame gaps early
  • Don’t force external sealing on a damp or frosty day

Record which products went where in the handover file. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. We can confirm the handover information you need when we quote.

Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors. Proper preparation, with the right silicone first time, keeps it off the defects list.

Why it’s worth doing now in Wainscott

A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Questions about Wainscott

Can you work at a site such as Gun Lane Business Centre, by Wainscott?

Yes, sites like Gun Lane Business Centre are within our area, along with the rest of Wainscott. A few photos and the unit address let us price the work.

Can you work around term dates at a campus such as University of Kent - Medway Campus?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can the sealant be colour-matched?

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

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Is the mastic package guaranteed?

Each package is signed off with a 12-month workmanship guarantee. Damage by others after we have finished isn’t covered.

Can fire-rated sealing at service penetrations be included?

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.

What happens if the weather stops external sealing?

External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work so we usually switch to internal work when that happens.

General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What affects the price in Wainscott

Quotes vary with the job. It mainly depends on:

  • How much there is to seal
  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • How accessible the joints are

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Any specification or named product
  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Facades, frames and programmes in Wainscott

Wainscott lies within about 2 miles of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Rainfall across the South East, Wainscott included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

On a campus such as University of Kent - Medway Campus, which lies south-east of Wainscott, new teaching buildings and residences are normally built and refurbished around the academic year. For a contractor at a hotel such as RBS Hotel, 1.1 miles to the south-west of Wainscott, the mastic often has to be finished before a reopening date. New wings at hospitals like Medway Maritime Hospital (to the south-east of Wainscott) bring long runs of window and panel joints to seal.
