How we handle construction mastic in Skippers Hill

Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. New and existing joints then get the same preparation. If you have cracks opening in caulked internal joints and mastic snags holding up handover, we can help, on cladding and panel joints, brick and block movement joints and sanitary and kitchen joints alike. A single leaking joint is often how a building in Skippers Hill first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Conversions of older rural buildings near smaller places such as Skippers Hill bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Surface by surface

Internal decorators’ caulk

Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move while moving joints need a flexible sealant.

Kitchens and utility areas

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product.

Facades, frames and programmes in Skippers Hill

Skippers Hill sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Skippers Hill is about 37 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

School extensions, at buildings such as Skippers Hill Manor School, usually run to the summer holidays, mastic included. Extensions at sites like Crowborough War Memorial Hospital, 4.1 miles north-west of Skippers Hill, usually sit beside working departments, and the mastic follows strict access rules.

Skippers Hill is about 4 miles south-east of Crowborough, in East Sussex.

Doing it in-house

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

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Why act early in Skippers Hill

A quick bead over a damaged joint can get an area past inspection, but it won’t last. Sealant can’t grip a contaminated or existing bead. We cut out and redo the joint properly. One visit to deal with every failing joint makes more sense than several trips to a place like Skippers Hill, rather than one at a time. Photos of every joint help us quote for the whole job.

Pricing mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Common questions from Skippers Hill clients

Would you work within a site like Crowborough War Memorial Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Does your area include sites such as Station Road Industrial Estate, near Skippers Hill?

Yes. Our area takes in Skippers Hill and its surroundings, with estates and business parks such as Station Road Industrial Estate included. Photos and a short description are enough for a first look.

How do you choose the sealant?

The specification comes first, if there is one. 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.

Can you work plot by plot or floor by floor?

Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready.

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Does weather affect external mastic work?

Outside, the joint has to be dry and the temperature within the product’s limits. Damp, frost or condensation on frames can stop work so we usually switch to internal work when that happens.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Common problems we fix in Skippers Hill

Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.

Any of the following is a good reason to get the joints checked over:

  • Missed perimeter joints on a new elevation
  • Failed sealant in an existing building being refurbished
  • Snag items on joints that need redoing before handover
  • Inconsistent sealant finishes from plot to plot

For contractors refurbishing units at places like Station Road Industrial Estate, which lies south-east of Skippers Hill, the mastic covers cladding panels, roller-door and window perimeters.

What to look for in a quote

  • Will CSCS-carded applicators be on site?
  • Whether primer will be used where the manufacturer specifies it
  • How they handle RAMS and site documents
  • How they’ll work around occupants
