Construction mastic near Wrotham Heath

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Rework caused by others damaging completed areas
  • Oversized gaps that need packing or adjustment by others
  • Deciding which fire-stopping product a penetration needs

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Construction mastic in Wrotham Heath, done properly

We work to the specification and the programme, not to habit. Where the specification names a product, we use it. Backing, primer and depth follow what the sealant maker sets out, so the joints perform as the designer intended. Site teams most often ask us about cracks opening in caulked internal joints and old sealant on a refurbishment that needs stripping before new work, on cladding and panel joints, sanitary and kitchen joints and internal decorators’ caulk. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Wrotham Heath is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Construction in and around smaller places such as Wrotham Heath is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Our process

The first thing on site is a walk round with your contact, 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. Rural sites near Wrotham Heath may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. Final snagging is completed and the 12-month guarantee applies.

Before we start on site

  • Let building users know which areas are affected
  • Let us know about inductions and permits
  • Send any specification or drawings in advance

Request a quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

Quoting for work in Wrotham Heath

Each job is priced on its own details. The main factors are:

  • How much existing material needs removing
  • How accessible the joints are
  • Quantities, in metres or numbers
  • Phasing around occupants

A quote for mastic packages depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • The site address and postcode
  • Any dates the work must fit around
  • Any specification or named product
  • Approximate linear metres or a joint schedule

To get a fixed quote, call the office on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.

Your questions answered

Does your area include sites such as Invicta Business Park, near Wrotham Heath?

Yes. Estates, retail parks and business parks around Wrotham Heath, Invicta Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

Is Wrotham Heath off your patch?

Not at all. Wrotham Heath is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Will you stick to the specified products?

We work to the specification and the manufacturer’s installation guidance. Preparation, backing and depth follow the product guidance.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

What joints do you seal on a new build?

External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. We price to the specification and drawings.

Are you CHAS accredited?

We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.

Mastic packages on Wrotham Heath sites

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. Wrotham Heath has several hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Projects at schools like Platt Church of England Voluntary Aided Primary School work to term dates, so mastic is programmed tightly. For contractors refurbishing units at places like Invicta Business Park, 1.1 miles to the north-west of Wrotham Heath, the mastic covers cladding panels, roller-door and window perimeters. Historic houses such as Old Soar Manor (2.7 miles south-west of Wrotham Heath) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

How the job changes by surface

Bathrooms, en suites and washrooms

Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere following the programme.

Snagging before handover

Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit.

Looking after the joints

For the best life from the joints:

  • Brief following trades on areas that have been sealed
  • Put any product change through the designer first
  • Ask installers to correct oversized gaps first
  • Ask for joint and product checks before the package is urgent

Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.

In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
