Mastic sealing for businesses in West Farleigh

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

Mastic sealing in West Farleigh, done properly

Treatment starts with a proper look: 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, balcony and threshold joints and window and door perimeters on blocks, and the usual reasons a site gets in touch are failed external movement joints and the same joint failures repeated across a portfolio. For commercial sealant work in West Farleigh, you deal with one contact from quote to sign-off, whether it’s one building or several.

For owners with a single building near West Farleigh, we plan to finish in one visit where possible. Send photos of the frames and joints and we will give a fixed quote.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building around West Farleigh, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Getting the site ready

For owners and agents in West Farleigh

At about 29 miles from central London, West Farleigh is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. West Farleigh sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

If you look after a block within reach of East Farleigh station (1.4 miles east of West Farleigh), frame and balcony mastic can be renewed on one programme. If you own or manage units on a site such as Tovil Green Business Park (2.5 miles east of West Farleigh), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

When to call us in West Farleigh

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

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

  • Damp patches beside frames
  • Complaints coming in block by block
  • Window mastic that has split and shrunk
  • Estate-wide sealant that is simply worn out

Trustees of buildings like All Saints Church can bring frame and external mastic into a planned maintenance list.

What to look for in a quote

  • Whether primer will be used where the manufacturer specifies it
  • Which product they’ll use, and why it suits the joint
  • Proof of insurance

Our contractor checklist

Quoting for work in West Farleigh

These are the things that shape the price:

  • How much existing material needs removing
  • The site’s rules and procedures
  • Phasing around occupants
  • The total length or number of joints

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

Before you send an enquiry

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

  • Any dates the work must fit around
  • The site address and postcode
  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, phone 01277 525 020 or email us.

Common questions from West Farleigh clients

Can you quote for a block close to East Farleigh station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Do you cover business parks and estates near West Farleigh, such as Tovil Green Business Park?

Yes. Estates, retail parks and business parks around West Farleigh, Tovil Green Business Park among them, are all within reach. A few photos and the unit address let us price the work.

Do you check for asbestos in old sealant?

Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

How many days will you need on site?

That varies with the scale of the job, though a typical visit typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How do you handle work on occupied blocks?

The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.

How do you reach windows on upper floors?

It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

What happens if it’s left?

Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. Older rural buildings around West Farleigh move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Different surfaces, different methods

External movement joints

External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.

Communal areas

Low-level communal joints get damaged more than most, so they often need renewing sooner.

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in West Farleigh can sit alongside others in a wider programme across Kent.
