Construction mastic in Lenham Forstal, done properly

The specification and the programme set the job, not to habit. If a product is named, that’s what goes in. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. Site teams most often ask us about window and door perimeters that won’t pass inspection and sanitary sealant damaged by following trades, across brick and block movement joints, floor and skirting junctions and cladding and panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lenham Forstal it comes down to the same thing: the right product in a properly prepared joint.

Conversions of older rural buildings near smaller places such as Lenham Forstal bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Building owners, agents and FMs in Lenham Forstal

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a day or two on a small fit-out and several weeks on a large multi-storey package, and our waste is bagged and taken away as we go. If others near Lenham Forstal need work, visits can be combined. A fixed quote is given before anything starts.

  1. We price from the drawings, specification and programme you send.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

Preparing the site

  • Let us know about inductions and permits
  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints

What sets the cost

The price varies from site to site. Expect it to depend on:

  • Backing rod, priming and other preparation
  • Specialist products, such as fire-rated or hygienic sealants
  • Access and working height
  • How much there is to seal

Pricing mastic packages depends on how many there are, their condition and the access. Call for a quote.

Details that help us quote

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

  • Photos of the joints, close up and from further back
  • Access details, including height
  • Where the site is, with the postcode
  • Any dates the work must fit around

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or send photos by email if you’d rather talk the job through.

Honest limits

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

  • Rework caused by others damaging completed areas
  • Frames fitted out of tolerance
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)

If you are not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

FAQs: Lenham Forstal

Could you schedule work at a campus like Canterbury Christ Church University for the vacation?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a smaller place like Lenham Forstal outside your area?

No. Places such as Lenham Forstal are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

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.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How do I request a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

When to call us in Lenham Forstal

A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.

It’s worth sending us details if you spot any of the following:

  • Sealant knocked or painted over by other trades
  • Window and door perimeters that won’t pass inspection
  • Internal caulk splitting as the building dries out
  • Frame gaps too wide for sealant alone

For a contractor at a hotel such as Chilston Park Hotel, which lies west of Lenham Forstal, the mastic often has to be finished before a reopening date.

What your quote should include

  • How they’ll work around occupants
  • What level of public liability insurance do they hold?
  • Is the sealant right for the movement and the substrate?
  • Will RAMS and insurance details be available?

Choosing a commercial sealant contractor

Doing it in-house

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.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
