Mastic sealing across Horney Common

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

Maintenance after handover

After handover, a little attention goes a long way:

  • Avoid piecemeal callouts where you can
  • Start inspections with the most exposed faces
  • Share your contractor requirements early
  • Check the asbestos register before any old mastic is disturbed

Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.

Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Mastic sealing in Horney Common, done properly

Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on shopfronts below residential blocks, communal kitchens and washrooms and balcony and threshold joints, and what we are called in for most is communal area joints that look neglected and repeated reactive repairs to the same buildings. One point of contact handles commercial sealant work in Horney Common from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Owners and agents with buildings around smaller places such as Horney Common tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Mastic sealing in Horney Common: the local picture

Central London is about 34 miles from Horney Common. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Buildings close to stations like Buxted station, 2.8 miles to the south-east of Horney Common, are often flats over shops, with frame mastic to keep sound. Trustees of buildings like Christ Church can bring frame and external mastic into a planned maintenance list.

Horney Common is about 3 miles north of Uckfield, in East Sussex. Commercial clients in Horney Common can call on us for mastic joints, as part of our coverage of East Sussex. We work across 308 places in East Sussex, from busy centres to rural villages. There’s a separate page for Brighton, roughly 16 miles from Horney Common.

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent.

Tenement and older buildings

Older mastic can contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Horney Common can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First we look at the mastic on each building and note what needs replacing.
  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. Old sealant is stripped and each face prepared back to firm 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.

Questions about Horney Common

Can you work at a site such as Ashdown Business Park, by Horney Common?

Yes, sites like Ashdown Business Park are within our area, along with the rest of Horney Common. Send details of the unit and the work through our quote form for a quick quote.

Is Horney Common off your patch?

No. Places such as Horney Common are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What will the job cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you guarantee the mastic work?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

What we’re called out for in Horney Common

Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Regular cleaning wears them further.

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

  • Complaints coming in block by block
  • Cracked, hardened mastic round windows on a block
  • Mastic failing across several blocks on an estate
  • Occupiers reporting cold air round windows

Landlords with units on estates such as Ashdown Business Park, 1.5 miles to the south of Horney Common, can bring frame, door and external mastic across several units into one programme.

What to look for in a quote

  • Will failed sealant be removed rather than covered?
  • Their plan for phasing and protecting the area
  • Proof of insurance
  • How the joint faces will be prepared and primed
