Construction mastic for businesses in Fosten Green

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Construction mastic in Fosten Green

The specification and the programme set the job rather than whatever product is to hand. Where the specification names a product, we use it; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. If you have bath and shower joints scraped during the final clean and missed perimeter joints on a new elevation, we can help, whatever the surface. Looking for mastic applicators who cover Fosten Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Construction in and around smaller places such as Fosten Green 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.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Plan external elevations with the weather in mind
  • Ask cleaners to use soft cloths around fresh sealant
  • Record the products used in the O&M file
  • Share drawings and the specification as soon as possible

Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead so keep them off the joints.

One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. Checking perimeters before internal finishes go on avoids it.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Designing joint widths or choosing the specification (that sits with the designer)
  • Approving fire stopping as compliant

If you’re not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer.

Joints and surfaces we work on

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

Leave it or put it right?

Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal, which is a much smaller cost. If the frame is life-expired, we’ll tell you. Around Fosten Green, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why appoint us

  • Colour agreed before work starts
  • Fixed quotes based on photographs, drawings or a visit
  • Public liability insurance in place
  • Work carried out by CSCS-carded applicators

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. For a building around Fosten Green, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We start with the drawings, specification and programme.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Plots or floors are sealed as they’re handed over.
  5. Joints are prepared, backed and sealed to the specification.
  6. After snagging, the work is handed over under our 12-month guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Tell staff and tenants when we will be in
  • Flag any permit to work we will need

Advice

What the job involves on each surface

External facade and movement joints

Many facade substrates need a primer before sealing. We prime where the manufacturer specifies.

Snagging before handover

Snagging is often the final mastic stage. We can work through the snag list area by area, cutting out damaged joints and resealing them properly.

Commercial clients in Fosten Green

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

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.

Common questions from Fosten Green clients

Is Fosten Green too small for you to travel to?

Not at all. Fosten Green is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Does your area include sites such as Business Park, near Fosten Green?

Yes. Our area takes in Fosten Green and its surroundings, with estates and business parks such as Business Park included. Photos and a short description are enough for a first look.

Can you seal external joints in wet or cold weather?

External mastic depends on conditions: each sealant has a temperature range, and the joint must be dry. We plan external elevations with that in mind.

Can you come in just for snagging?

Yes. Damaged, missed or untidy joints are stripped and done again properly to suit the programme.

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 plot by plot or floor by floor?

We work to your programme. Share the release dates and we’ll match our work to them, sealing as areas become ready.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Construction mastic in Fosten Green: the local picture

Fosten Green lies roughly 42 miles out from central London. 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. Fosten Green is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

For contractors refurbishing units at places like Business Park, 1.7 miles to the south-east of Fosten Green, the mastic covers cladding panels, roller-door and window perimeters. Extensions at sites like Benenden Hospital (0.9 miles south of Fosten Green) normally sit beside working departments, and the mastic follows strict access rules.

Fosten Green is about 11 miles west of Ashford, in Kent. Across the TN27 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Fosten Green is one of 931 places in Kent on our list. Sites around Brighton have their own page, about 38 miles away.
