Mastic sealing near East Hoathly

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

After the work

Keep the joints in good shape with a few simple steps:

  • Have the asbestos survey to hand for older buildings
  • Keep a record of when each building was resealed
  • Share your contractor requirements early
  • Look at the sunniest and most exposed elevations first

Keep records of when each building was resealed. It helps plan the next round and gives you a history.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

Mastic sealing in East Hoathly

For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you have failed external movement joints and damp patches beside frames, we can put it right. A single leaking joint is often how a building in East Hoathly first comes to us: we look at the rest while we’re there and tell you what we find.

Around smaller places like East Hoathly, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Questions we’re asked in East Hoathly

We manage a building near Uckfield station. Can you help?

Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.

Is East Hoathly too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What if the old mastic contains asbestos?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

How long does a job like this take?

That varies with the scale of the job, but the work usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Do you do block-wide mastic programmes?

Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Materials that need asbestos testing before work
  • Leaks through the frame itself rather than the perimeter
  • Broken glass or failed sealed units

If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Mastic sealing in East Hoathly: the local picture

East Hoathly is about 41 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

For a school such as East Hoathly CofE Primary School, perimeter mastic on windows and doors is a holiday job. With historic buildings such as Horselunges Manor, 4.6 miles south-east of East Hoathly, in the wider area, owners of older properties around East Hoathly should expect mastic to need a product that suits old masonry.

East Hoathly is about 4 miles south-east of Uckfield, in East Sussex. Any commercial site in East Hoathly is covered, for single jobs and planned programmes alike. 308 places across East Sussex fall within our area, including East Hoathly. Brighton is covered too, around 14 miles from East Hoathly.

Commercial clients in East Hoathly

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in East Hoathly can sit alongside others in a wider programme.

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Common problems we fix in East Hoathly

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Regular cleaning wears them further.

Typical triggers for a call:

  • Estate-wide sealant that is simply worn out
  • Cracked, hardened mastic round windows on a block
  • No planned programme for sealant
  • Movement joints with sealant missing

Churches, halls and community buildings such as The Parish Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

What to look for in a quote

  • Do they follow the manufacturer’s priming guidance?
  • How they’ll work around occupants
  • How joint depth will be controlled
  • Health and safety accreditation such as CHAS

Our process

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Failed mastic is removed and the faces taken back to sound, dry material.

  6. Completed joints are inspected and carry a 12-month workmanship guarantee.
