Construction mastic across Bolney
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Surface by surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services so we’ll flag where the detail needs something different. Record requirements are agreed with the quote.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification and set the depth with backing where needed.
Construction mastic in Bolney, done properly
Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can normally carry on while the outside waits. If you’re dealing with sanitary sealant damaged by following trades and a mastic package split between trades with no clear owner, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Bolney it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in and around smaller places such as Bolney 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

How a job runs
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Bolney need work, visits can be combined. A fixed quote is given before anything starts.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.

Why deal with it now?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go and saves applicators coming back again and again. We can run snagging as its own phase before handover. One visit to deal with every failing joint makes more sense than several trips to a place like Bolney, rather than one at a time. Send photos of each area and we will quote for the lot.
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
What you get with us
- Work to your specification and the manufacturer’s guidance

What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Designing joint widths or choosing the specification (that sits with the designer)
- Oversized gaps that need packing or adjustment by others
- Faulty frames rather than failed sealant
If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think.
What we seal
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
- Cladding and panel joints
- Brick and block movement joints
FAQs: Bolney
Does your area include sites such as Crosspot Industrial Estate, near Bolney?
Yes. We cover Bolney and the area around it, including industrial estates, business parks and retail parks such as Crosspot Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Is a hospital such as The Dene Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
Construction mastic in Bolney: the local picture
Rainfall across the South East, Bolney included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Bolney is about 35 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
For contractors refurbishing units at places like Crosspot Industrial Estate (0.8 miles south-west of Bolney), the mastic covers cladding panels, roller-door and window perimeters. Historic houses such as Ockenden Manor (to the east of Bolney) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Bolney is about 4 miles north-west of Burgess Hill, in West Sussex. We cover commercial sites throughout Bolney, for single jobs and planned programmes alike. Across West Sussex, 373 places are covered, Bolney among them. We also cover Brighton, around 12 miles from Bolney.
We take on mastic packages across the RH17 postcode area, whatever the building. For a building on The Street, Cherry Lane and Top Street or nearby, send details and we’ll quote for mastic packages. We also cover Crosspost (1 mile south-west), Twineham Green (2 miles south), Twineham (2 miles south), Wineham (3 miles south-west) and Kent Street (3 miles south-west) for mastic packages. Nearby towns on our patch include Crawley (8 miles north), Horsham (7 miles north-west), Worthing (15 miles south-west), Haywards Heath (5 miles east), Burgess Hill (4 miles south-east) and East Grinstead (12 miles north-east).
Around Bolney
Bolney’s nearest station is Wivelsfield station, roughly 4.1 miles south-east of the centre. Well-known places in the area include The Dene Hospital (2.6 miles south-east) and Cuckfield Museum (2.6 miles east). Not far away are Blunts Wood and Paiges Meadow.
Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What we’re called out for in Bolney
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
Site and facilities staff are often the first to spot these:
- Bath and shower joints scraped during the final clean
- Cracks opening in caulked internal joints
- Different trades sealing to different standards
- Perimeter gaps outside the sealant’s range
For contractors at a school such as Bolney CofE Primary School, sealing has to be finished before term starts.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
- Proof of insurance
