About our construction mastic in Worthing
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. We work on sanitary and kitchen joints, window and door perimeters and internal decorators’ caulk, and the usual reasons a site gets in touch are old sealant on a refurbishment that needs stripping before new work and snag items on joints that need redoing before handover. Looking for mastic applicators who cover Worthing? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
On larger schemes in and around Worthing, mastic is often programmed plot by plot or floor by floor. CSCS-carded applicators work to the site’s rules and the specification, and any snags are cleared before handover.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
From enquiry to sign-off
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Jobs in a large place like Worthing are often on business parks, retail sites or campuses with their own sign-in and permit rules. Tell us about inductions, permits and site hours so the plan fits.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings
- Agree which areas must stay open

What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Glazing units that are cracked or misted
- Designing joint widths or choosing the specification (that sits with the designer)
- Approving fire stopping as compliant
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
What we seal
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Brick and block movement joints
- Window and door perimeters
- Cladding and panel joints
- Floor and skirting junctions
Questions we’re asked in Worthing
Could you schedule work at a campus like Worthing College for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Our building in Worthing is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you work plot by plot or floor by floor?
We follow the trades through the building. Areas are sealed as they’re released by the site team, and we will raise anything that holds the work up.
What accreditations do you hold?
CHAS and Constructionline are both in place, and each applicator is CSCS-carded. Public liability insurance is in place.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Quoting for work in Worthing
Quotes vary with the job. Expect it to depend on:
- Quantities, in metres or numbers
- Any access equipment needed
- Distance, for remote addresses
- Whether the work must be split into stages
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Specification clauses that apply
- When you need the work done
- The postcode of the building
- Photos of the joints, close up and from further back
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
After the work
Keep the joints in good shape with a few simple steps:
- Protect sealed areas from following trades
- Brief the final clean team to avoid blades near sealant
- Put any product change through the designer first
- Bring the mastic contractor in after the last trades are through
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We flag them as soon as we see them.
Sites and facades in and around Worthing
The sea is no more than about 2 miles from Worthing. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Worthing is about 48 miles from central London. 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.
Hospital estates such as Worthing Hospital (1.6 miles east of Worthing) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. When a college such as Worthing College (to the north-east of Worthing) builds or refurbishes, the mastic package usually has to fit around students and staff. New units and refits on sites such as Goring Business Park, 1.1 miles south-west of Worthing, need their panel and perimeter joints sealed to the specification.

What happens if it’s left?
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites rather than at the snagging stage. Called in at the end, the same issues surface during handover. On a busy site in a large place like Worthing, a failed joint gets worse with every day of use. Catching it early keeps the fix simple.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
