Construction mastic for Tisman's Common sites

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

When to bring in a specialist

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

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.

Construction mastic in Tisman's Common

External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal areas can usually carry on while the outside waits. The enquiries we see most involve failed sealant in an existing building being refurbished and a mastic package split between trades with no clear owner, on floor and skirting junctions, window and door perimeters and cladding and panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Tisman's Common is the same: the right product in a properly prepared joint.

Construction in and around smaller places such as Tisman's Common is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Every job we finish is backed by a 12-month workmanship guarantee, in Tisman's Common as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered

Is a smaller place like Tisman's Common outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you take on work at estates like The Old Brickworks Industrial Estate, close to Tisman's Common?

Yes, sites like The Old Brickworks Industrial Estate are within our area, along with the rest of Tisman's Common. Send details of the unit and the work through our quote form for a quick quote.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Can you work to our specification?

We use the product the specification names. Any suggested alternative is put to you before anything changes.

Do you guarantee new-build sealant work?

The work is guaranteed for 12 months on the workmanship. Protecting sealed areas from following trades helps avoid damage.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Frames fitted out of tolerance
  • Approving fire stopping as compliant
  • Faulty frames rather than failed sealant

If you are not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer.

How the job changes by surface

Kitchens and utility areas

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used and hygienic or food-safe grades wherever food contact is possible.

Fire-rated sealant where specified

Not every penetration suits a sealant. Other products are used for some services and gaps, and we’ll tell you if the detail calls for something else. Tell us what records you need and we’ll confirm with the quote.

Looking after the joints

After handover, a little attention goes a long way:

  • Ask for joint and product checks before the package is urgent
  • Ask cleaners to use soft cloths around fresh sealant
  • Protect sealed areas from following trades
  • Flag uneven or tapered frame gaps early

If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit, priced as part of the package or separately.

In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Tisman's Common are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. A fixed quote sets out the scope, the products and the sequence.
  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. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Before we start on site

  • Explain the parking and delivery arrangements
  • Flag any permit to work we’ll need
  • Confirm the product named in the specification

Getting a fixed quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

What sets the cost

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

  • Quantities, in metres or numbers
  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • Whether the work must be split into stages

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • The type of building and who uses it
  • Specification clauses that apply
  • A wide shot and a close-up of the area
  • The site address and postcode

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send photos by email with what you know.

Sites and facades in and around Tisman's Common

Central London is about 33 miles from Tisman's Common. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Tisman's Common is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.

New units and refits on sites such as The Old Brickworks Industrial Estate, 1 mile north-east of Tisman's Common, need their panel and perimeter joints sealed to the specification. When a school such as Pennthorpe School is extended or refurbished, the mastic package is often squeezed into the holidays. For a contractor at a hotel such as Goblin's Pool Hotel, 0.6 miles east of Tisman's Common, the mastic often has to be finished before a reopening date.
