Construction mastic for Fisher sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Building owners, agents and FMs in Fisher
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
How we handle construction mastic in Fisher
Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items. Our aim is joints that pass at the first inspection. We work on cladding and panel joints, floor and skirting junctions and internal decorators’ caulk, and the usual reasons a site gets in touch are existing joints on a refurb that need cutting out and resealing and oversized or tapered gaps around new frames. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Fisher is the same: the right product in a properly prepared joint.
For a site near Fisher, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we’ll quote to suit.
Work we carry out in West Sussex comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

After the work
Problems stay small when the joints are checked regularly. Specifically:
- Flag uneven or tapered frame gaps early
- Keep finished joints away from paint, plaster and scrapers
- Put any product change through the designer first
- Get the mastic subcontractor involved early in the programme
Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.
How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Fisher 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.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- Final snagging is completed and the 12-month guarantee applies.

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Specifying the product where the designer hasn’t
- Oversized gaps that need packing or adjustment by others
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think.
Where we work in Fisher

General trades versus a specialist
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 easy to get wrong without experience.
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.
Sites and facades in and around Fisher
With the shore within about 2 miles, Fisher counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.
When units on a site such as Quarry Lane Industrial Estate, 2.3 miles to the north of Fisher, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Projects at schools like Chichester High School For Girls work to term dates, so mastic is programmed tightly.
Fisher is about 3 miles south of Chichester, in West Sussex. Anywhere in PO20, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Fisher is one of 373 places we cover in West Sussex for mastic packages. We also cover Portsmouth, some 14 miles away.

Common questions from Fisher clients
Is a smaller place like Fisher outside your area?
No. Places such as Fisher are covered as much as the big towns. 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.
Can being near the sea in Fisher affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
How do you work with the site programme?
We work to your programme. Tell us the sequence and we’ll plan applicators around it.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Signs you need construction mastic in Fisher
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
Things that usually lead to an enquiry:
- Oversized or tapered gaps around new frames
- Mastic snags holding up handover
- Sanitary sealant damaged by following trades
- Inconsistent sealant finishes from plot to plot
Building work at universities like University of Chichester, 2.4 miles to the north-east of Fisher, is often timed for the summer, mastic included.
