Mastic sealing in Finberry

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

Mastic sealing for commercial buildings in Finberry

We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. We work on communal entrances and stairwells, window and door perimeters on blocks and shopfronts below residential blocks, and the usual reasons a site gets in touch are draught complaints from residents or tenants and a mix of products and colours from past repairs. Most enquiries from Finberry 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.

In and around smaller places like Finberry, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Travel to remote or island sites
  • The total length or number of joints
  • The product specified
  • The size and state of each joint

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.

Before you send an enquiry

However big the job, the same details help:

  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • The asbestos register, for older buildings
  • How the joints are reached, and at what height

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call 01277 525 020 or email the details over if you’d rather talk the job through.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near Finberry need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we look at the mastic on each building and note what needs replacing.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Have the specification and drawings to hand
  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Frames that are rotten, warped or broken
  • Broken glass or failed sealed units
  • Masonry that has broken away beside the joint

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly before you book.

What we seal

  • Communal kitchens and washrooms
  • Shopfronts below residential blocks
  • Window and door perimeters on blocks
  • External wall and movement joints
  • Communal entrances and stairwells
  • Balcony and threshold joints

Work for main contractors and building owners

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Common questions from Finberry clients

Can you quote for a block close to Ashford International station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.

Is a smaller place like Finberry outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Does weather matter for sealant work?

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.

Do you do block-wide mastic programmes?

We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Do you guarantee the mastic work?

Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.

Do you check for asbestos in old sealant?

Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Block-wide mastic in Finberry

Finberry is about 50 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Finberry sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

Historic properties like Godinton House (4 miles north-west of Finberry) show the age of some local stock, where frame mastic must suit soft brick or stone. If you’re responsible for a building such as Church of St Mary, frame and door mastic needs the same attention as any other property. If you look after a block within reach of Ashford International station, 2 miles to the north-west of Finberry, frame and balcony mastic can be renewed on one programme.

Finberry is about 2 miles south-east of Ashford, in Kent. Businesses, contractors and managing agents in Finberry use us for work on mastic joints. Finberry is one of 931 places in Kent on our list. Sites around Brighton have their own page, about 49 miles away.

If you need mastic sealing in TN25, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

Nearby places we also cover include Cheeseman's Green (1 mile south), South Willesborough (1 mile north), Park Farm (1 mile west), Newtown (1 mile north-west) and Kingsnorth (1 mile west). A short drive away, we cover Canterbury (14 miles north-east), Folkestone (12 miles east), Faversham (14 miles north), Hythe (9 miles east), Davington (14 miles north) and Preston (13 miles north).

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

After the work

Once the work is signed off, these steps help:

  • Start inspections with the most exposed faces
  • Avoid piecemeal callouts where you can
  • Protect low-level joints in entrances
  • Have the asbestos survey to hand for older buildings

Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.

One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
