How we handle construction mastic in Green Street
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal areas can usually carry on while the outside waits. If you have existing joints on a refurb that need cutting out and resealing and missed perimeter joints on a new elevation, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Green Street is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Sites around smaller places like Green Street can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Questions about Green Street
Is Green Street too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can work at a site such as Bexhill 6th Form College fit around teaching?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you guarantee new-build sealant work?
The work is guaranteed for 12 months, covering how we sealed. Protecting sealed areas from following trades helps avoid damage.
Can you work to our specification?
We use the product the specification names. If we think an alternative would suit better, we put it to you first.
What happens if the weather stops external sealing?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Sealing in poor conditions risks adhesion failure.
Can you come in just for snagging?
Yes. Damaged, missed or untidy joints are stripped and done again properly.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Oversized gaps that need packing or adjustment by others
- Damage to finishes by other trades after we have sealed
- Joint design decisions that belong to the architect or engineer
If in doubt, call 01277 525 020 or send photos by email and we will say what we think before you book.
What we seal
- Sanitary and kitchen joints
- Brick and block movement joints
- Internal decorators’ caulk
- Window and door perimeters
- Cladding and panel joints
- Floor and skirting junctions
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme, and our waste is bagged and taken away as we go. If others near Green Street need work, visits can be combined. You’ll have a fixed quote before work starts.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Point out parking and an unloading spot
- Send any specification or drawings in advance
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Mastic packages on Green Street sites
Green Street is within about 3 miles of the coast. 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. Green Street lies roughly 50 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
For contractors refurbishing units at places like Pebsham Rural Business Centre, 1.8 miles to the south of Green Street, the mastic covers cladding panels, roller-door and window perimeters. School extensions, at buildings such as Crowhurst CofE Primary School, typically run to the summer holidays, mastic included. Extensions at sites like Bexhill Hospital (to the south-west of Green Street) usually sit beside working departments, and the mastic follows strict access rules.
Green Street is about 2 miles west of Hastings, in East Sussex. We send applicators to Green Street for mastic packages, handled exactly as we handle every other area.

How the job changes by surface
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.
