Your questions answered
Will you take on work at estates like Crowborough Business Park, close to Marden's Hill?
Yes. Our area takes in Marden's Hill and its surroundings, with estates and business parks such as Crowborough Business Park included. Photos and a short description are enough for a first look.
Can you work on a hospital site such as Crowborough War Memorial Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do you seal on top of existing sealant?
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.
Can the building stay open while you work?
Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.
How long does a job like this take?
It depends on the scope, though a typical visit typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Do you do fire-rated sealing on new builds?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. The design and sign-off belong to the designer, fire engineer or building control.
About our construction mastic in Marden's Hill
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. If you have early adhesion failures on new external joints and missed perimeter joints on a new elevation, we can help. Most enquiries from Marden's Hill start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in and around smaller places such as Marden's Hill is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Rework caused by others damaging completed areas
- Designing joint widths or choosing the specification (that sits with the designer)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If you’re not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer.

Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Owners, agents and contractors
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Contractors’ notes for Marden's Hill
Marden's Hill sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Marden's Hill is about 31 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
For contractors at a school such as St John's Church of England Primary School, sealing has to be finished before term starts. New units and refits on sites such as Crowborough Business Park (1.3 miles south-east of Marden's Hill) need their panel and perimeter joints sealed to the specification. Historic houses such as Groombridge Place (to the north-east of Marden's Hill) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Marden's Hill is about 2 miles north-west of Crowborough, in East Sussex. We send applicators to Marden's Hill for mastic packages, handled exactly as we handle every other area.
