About our construction mastic in Dukes Green
Since 2005 we have worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in Dukes Green, send drawings through our quote form, or phone or email us to talk it through. We work on window and door perimeters, internal decorators’ caulk and sanitary and kitchen joints, and what we’re called in for most is frame perimeters left unsealed or poorly sealed and snag items on joints that need redoing before handover. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Dukes Green is the same: the right product in a properly prepared joint.
Sites around smaller places like Dukes Green can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. Rural sites near Dukes Green may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready
- Agree which areas must stay open
- Share your working hours and any access restrictions
- Make sure the joints can be reached

Sites and facades in and around Dukes Green
The sea is no more than about 3 miles from Dukes Green. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Central London is about 50 miles from Dukes Green. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
For contractors refurbishing units at places like Berwick Court Farm Business Park, which lies north of Dukes Green, the mastic covers cladding panels, roller-door and window perimeters. Building work at universities like University of Brighton (to the west of Dukes Green) is often timed for the summer, mastic included. New wings at hospitals like Chailey Heritage Marine Hospital, 3.8 miles west of Dukes Green, bring long runs of window and panel joints to seal.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
What affects the price in Dukes Green
Before we quote, we look at:
- Distance, for remote addresses
- Whether the work must be split into stages
- The site’s rules and procedures
- How much existing material needs removing
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Details that help us quote
To price the job accurately, we need to understand the site. Send us:
- The postcode of the building
- When you need the work done
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Questions we’re asked in Dukes Green
Can you work on a hospital site such as Chailey Heritage Marine Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does a coastal location like Dukes Green affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What does a mastic package normally include?
The scope comes from the specification and drawings, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
Will you stick to the specified products?
We follow the specified sealant and flag anything that doesn’t look right for the joint. Product standards such as BS EN 15651 are often named in specifications.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
How long does a job like this take?
It depends on the scope, but the work usually takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For bigger or phased jobs, we will set out a timescale with the quote.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Approving fire stopping as compliant
- Damage to finishes by other trades after we’ve sealed
- Joint design decisions that belong to the architect or engineer
Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly.
Joints and surfaces we work on
- Brick and block movement joints
- Floor and skirting junctions
- Cladding and panel joints
- Sanitary and kitchen joints
- Window and door perimeters
- Internal decorators’ caulk
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Brief the final clean team to avoid blades near sealant
- Keep finished joints away from paint, plaster and scrapers
- Use the product the specification names
- Check frame gaps are within the sealant’s range before sealing
Any damage after we’ve finished should go on the snag list right away. We can return to clear snags before handover as agreed in the quote.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.
