Questions we’re asked in Benenden

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

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Benenden off your patch?

No. Places such as Benenden are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does weather affect external mastic work?

Conditions have to suit the product before external work starts. Wet or cold joints cause adhesion problems so it’s better to wait.

Is colour matching possible?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.

What guarantee comes with a mastic package?

Each package is signed off with a 12-month workmanship guarantee. The guarantee covers our work, not later damage by other trades.

Construction mastic for commercial buildings in Benenden

External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal sealing often fills those days. We work on floor and skirting junctions, sanitary and kitchen joints and brick and block movement joints, and the usual reasons a site gets in touch are sanitary sealant damaged by following trades and existing joints on a refurb that need cutting out and resealing. Most enquiries from Benenden start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a site near Benenden, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Site staff or a sealant specialist?

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: 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.

Quoting for work in Benenden

Quotes vary with the job. Expect it to depend on:

  • Access and working height
  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Whether the building will be occupied during the work
  • A wide shot and a close-up of the area

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.

Surface by surface

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.

Kitchens and utility areas

Kitchen joints are sealed after fitting and before final clean. A kitchen-suitable sealant is used, food-safe where food contact is possible.

How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Rural sites near Benenden may need directions, gate codes or a contact on site. Add it to your enquiry and we will 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. 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.

Getting the site ready

  • Send your site hours and access windows
  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements

Request a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Construction mastic around Benenden: what changes locally

Central London is about 42 miles from Benenden. 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. 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.

Older buildings in the area around Benenden, such as Great Dixter, 5 miles south of Benenden, need care when sealed: the product has to suit soft or historic materials. Hospital estates such as Benenden Hospital (to the north-east of Benenden) 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.

Benenden is about 13 miles west of Ashford, in Kent. We send applicators to Benenden for mastic packages, handled exactly as we handle every other area. Our Kent coverage takes in 931 places, from busy centres to rural villages. Brighton is covered too, some 35 miles away.

Commercial sites across TN17 are covered for mastic packages. If your site is on The Street, Hortons Close and Iden Green Road or close by, send details and we’ll quote for mastic packages. Being close to the B2086, Benenden is straightforward for us to reach. Nearby places we also cover include Iden Green (1 mile south), Coursehorn (2 miles north-west), Baker's Cross (2 miles north-west), Swattenden (2 miles north-west) and Cranbrook (3 miles north-west) for mastic packages. Further afield, our area takes in Maidstone (14 miles north), Ashford (13 miles east), Royal Tunbridge Wells (14 miles west), Foley Park (15 miles north), Paddock Wood (11 miles north-west) and Tenterden (5 miles east).

What’s near Benenden

We work on buildings around King William IV Public House and the streets around them. A little further out are Mervyn Quinlan Museum (2 miles north-east) and Sissinghurst Castle (3.2 miles north).

Common problems we fix in Benenden

On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.

Clients usually get in touch after noticing something like this:

  • A long mastic snag list close to completion
  • Bath and shower joints scraped during the final clean
  • Cracks opening in caulked internal joints
  • New external sealant already peeling away

Projects at schools like Benenden Church of England Primary School work to term dates, so mastic is programmed tightly.

Our contractor checklist

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Frames fitted out of tolerance
  • Designing joint widths or choosing the specification (that sits with the designer)
  • Damage to finishes by other trades after we have sealed

If you’re not sure, just call 01277 525 020 or email us and we will give you a straight answer before you book.

What we seal

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