Construction mastic near Durrant Green

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

What we are called out for in Durrant Green

Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge. We flag them early rather than filling them with sealant that won’t last.

Any of the following is a good reason to get the joints checked over:

  • Caulk cracking where joints are moving more than expected
  • A long mastic snag list close to completion
  • External joints sealed in damp or cold conditions that are now failing
  • Sealant knocked or painted over by other trades

Hotel extensions and refits, at places such as Little Silver Country Hotel, 0.7 miles to the south of Durrant Green, usually run between busy periods, so the sealing is squeezed into short windows.

What your quote should include

  • Whether their applicators hold CSCS cards
  • How the existing material will be dealt with
  • How the joint faces will be prepared and primed
  • The named product and why it was chosen

Our contractor checklist

How we handle construction mastic in Durrant Green

Since 2005 we have worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Durrant Green, send drawings and the specification through our quote form. The enquiries we see most involve bath and shower joints scraped during the final clean and missed perimeter joints on a new elevation, across internal decorators’ caulk, window and door perimeters and cladding and panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Durrant Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In the countryside around places like Durrant Green, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

How the job changes by surface

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services. Tell us what records you need and we will confirm with the quote.

Snagging before handover

Snagging is often the final mastic stage. Snags are cleared room by room and damaged joints are redone rather than patched.

How a job runs

Before any cutting starts, the area is protected: 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. For work around Durrant Green, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Joints are prepared, backed and sealed to the specification.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements
  • Point out any areas we must not close

Related advice

Should maintenance staff do it?

Some joints are best left to specialists: 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.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Your questions answered

Is a smaller place like Durrant Green outside your area?

Not at all. Durrant Green is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Will you take on work at estates like Business Park, close to Durrant Green?

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can staff carry on working while you are here?

In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Can you seal external joints in wet or cold weather?

External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. External work is sequenced with some flexibility.

Do your applicators hold CSCS cards?

We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Tell us what site paperwork you need and we’ll confirm with the quote.

Can you work plot by plot or floor by floor?

Working to your programme, we seal each area as it’s handed over. The sequence is settled with your site team and updated as the programme moves.

New build and refits around Durrant Green

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 the external programme keeps a little slack. Durrant Green is about 44 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Historic houses such as Smallhythe Place (to the south of Durrant Green) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. When units on a site such as Business Park, 2.3 miles south-west of Durrant Green, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Durrant Green is about 8 miles west of Ashford, in Kent. Any commercial site in Durrant Green is covered. Across Kent, 931 places are covered, including Durrant Green. Sites around Brighton have their own page, roughly 40 miles from Durrant Green.

How the quote is worked out

Before we quote, we look at:

  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation
  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older
  • Any specification or named product
  • Photos of the joints, close up and from further back

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, give us a call on 01277 525 020 or email the details over.
