Construction mastic for businesses in Chiddingly
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

For construction mastic on a scheme in Chiddingly, send drawings through our quote form, or phone or email us to talk it through.

Common questions from Chiddingly clients
Does your area include sites such as Oakwood Business Park, near Chiddingly?
Yes. Our area takes in Chiddingly and its surroundings, with estates and business parks such as Oakwood Business Park included. Photos and a short description are enough for a first look.
Is Chiddingly too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can staff carry on working while you’re here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
What guarantee comes with a mastic package?
The work is guaranteed for 12 months on the workmanship. Protecting sealed areas from following trades helps avoid damage.
Do you use the sealant named in the specification?
We work to the specification and the manufacturer’s installation guidance. Preparation, backing and depth follow the product guidance.
Do you do internal caulk as well as external mastic?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. We price to the specification and drawings.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. For work around Chiddingly, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Tell staff and tenants when we will be in
- Tell us what induction or permit system the site runs
Quotes
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Why deal with it now?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects, especially externally. Where an alternative is genuinely suitable, we will say so. Halls, stores and units around places like Chiddingly may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why us?
- One phone line for London, the South East and Scotland
- Fully insured, including public liability cover
- Workmanship guaranteed for 12 months
- Specification-led, product-correct work

Signs you need construction mastic in Chiddingly
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
Common reasons buildings call us in:
- Snag items on joints that need redoing before handover
- Existing joints on a refurb that need cutting out and resealing
- Frame gaps too wide for sealant alone
- External joints sealed in damp or cold conditions that are now failing
Extensions at sites like Hellingly Hospital Railway (3.1 miles south-east of Chiddingly) typically sit beside working departments, and the mastic follows strict access rules.
Questions to ask before you book
- What the guarantee covers, and for how long
- Whether primer will be used where the manufacturer specifies it
- Their public liability cover
- Will RAMS and insurance details be available?
What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Frame gaps too wide for sealant, which the installer needs to correct
- Rework caused by others damaging completed areas
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What else we do in Chiddingly
Construction mastic in Chiddingly: the local picture
Chiddingly sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 43 miles from Chiddingly. 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.
Units on estates such as Oakwood Business Park, 1.1 miles south of Chiddingly, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Older buildings in the area around Chiddingly, such as Horselunges Manor, 2.7 miles south-east of Chiddingly, need care when sealed: the product has to suit soft or historic materials.
Chiddingly is about 4 miles north-west of Hailsham, in East Sussex. Chiddingly sits inside our coverage and the rest of East Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across East Sussex, 308 places are covered, Chiddingly among them. Brighton is covered too, around 15 miles from Chiddingly.

Nearby places we also cover include Whitesmith (1 mile west), East Hoathly (2 miles north-west), Halland (3 miles north-west), Shortgate (3 miles west) and Blackboys (4 miles north).

Near you in Chiddingly
Locally, jobs take us to sites close to The Six Bells Public House. For rail, the closest station is Berwick (Sussex) station, about 4.7 miles south. Nearby you’ll also find Sussex Farm Museum (2.8 miles north-east) and Tickerage Castle (4.8 miles north-west). Not far away are Selwyns Wood.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Put any product change through the designer first
- Ask installers to correct oversized gaps first
- Share drawings and the specification as soon as possible
- Keep finished joints away from paint, plaster and scrapers
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors. Proper preparation, with the right silicone first time, keeps it off the defects list.
