Mastic sealing for businesses in Rusher's Cross

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Mastic sealing in Rusher's Cross

We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. 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 external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and the same joint failures repeated across a portfolio. Searching for sealant specialists in Rusher's Cross? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Rural conversions near places like Rusher's Cross often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

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.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. Jobs in and around smaller places like Rusher's Cross are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Tell staff and tenants when we’ll be in
  • For older buildings, check the asbestos register before work

Advice

What happens if it’s left?

Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. Older rural buildings around Rusher's Cross 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.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Why appoint us

  • Colour options checked against the specified product
  • 12-month guarantee on workmanship
  • Work to your specification and the manufacturer’s guidance
  • Over 20 years of commercial sealing

How the job changes by surface

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.

Window and door perimeters on blocks

Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.

Common problems we fix in Rusher's Cross

UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.

Look out for the following:

  • Mastic failing across several blocks on an estate
  • Occupiers reporting cold air round windows
  • Damp patches beside frames
  • Repeated reactive repairs to the same buildings

Older community buildings, The Parish Church of St John the Baptist among them, often have frames of mixed ages whose mastic varies.

Questions to ask before you book

  • Their public liability cover
  • What site paperwork they can supply
  • How joint depth will be controlled
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Questions we’re asked in Rusher's Cross

Is Durgates Industrial Estate, near Rusher's Cross, within your area?

Yes. We cover Rusher's Cross and the area around it, including industrial estates, business parks and retail parks such as Durgates Industrial Estate. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

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

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Will residents or tenants be disturbed?

Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.

Do you supply RAMS and insurance details?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Do you do block-wide mastic programmes?

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

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Check the asbestos register before any old mastic is disturbed
  • Keep a record of when each building was resealed
  • Avoid piecemeal callouts where you can
  • Reduce knocks to communal area joints

Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.

One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
