Frontages, fit-outs and joints in Great Thorness
Great Thorness lies within about 1 mile of the sea. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. Where a frontage needs a particular colour, the product still has to suit that exposure. The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.
Parks like Porchfield Business Park (to the south-west of Great Thorness) see tenants come and go, and every move-in brings joints to seal.

Commercial sealant contractors for commercial buildings in Great Thorness
On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). We work on floor and threshold joints, washrooms and tea points and window and door perimeters, and the failures we are asked to look at most are layers of sealant, all of them failing and frame mastic that has hardened and come away from the wall. A specialist sealant contractor works differently from a general builder: in Great Thorness, that means joint design, primers and backing rod as standard.
Multi-site clients with buildings in and around Great Thorness can put several sites on one programme, so standards and paperwork match across every site.
Commercial sealant work around smaller places like Great Thorness tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Roof leaks that only look like a joint problem
- Old mastic that tests positive for asbestos
- Structural cracks or movement the joints weren’t designed for
Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly before you book.
What we seal
- Kitchen worktops and splashbacks

Cost factors for sealant joints
Your fixed quote is built from the real scope. It allows for:
- The size and state of each joint
- Induction, permit and paperwork requirements
- Specialist products, such as fire-rated or hygienic sealants
- Phasing around occupants
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- Rough lengths or quantities, or drawings if you have them
- Whether an asbestos survey exists
- The postcode of the building
- The product your specification calls for
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email the details over with what you know.
Your questions answered
Is Great Thorness off your patch?
Not at all. Great Thorness is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Does the sea air around Great Thorness change the choice of sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is the old sealant taken out first?
Full removal is part of every quote. A bead laid on old silicone peels away.
What do you need from us to quote?
The main factors are metres of joint, removal, access, the product and how many phases there are. To get a fixed price, send details through our quote form, or phone or email us.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Is your work guaranteed?
It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Different surfaces, different methods
Window and door perimeters
Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. The product depends on whether the joint will be painted.
Movement joints in walls and floors
Movement joints in walls and floors let the structure expand and contract. When the seal fails, debris gets in and the joint stops working. The joints are resealed using a sealant matched to the movement and any traffic.

Related advice
When to call us in Great Thorness
If only one face has lost its grip, that’s an adhesion failure. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.
If one of these sounds familiar, it’s time for a closer look:
- A top-up bead over failed sealant, now lifting
- Expansion joints with the sealant torn out
- Mouldy silicone around WCs, urinals and vanity tops
- Shrunken sealant along kitchen worktops and splashbacks
Occupiers with premises at both Porchfield Business Park and Carisbrooke Retail Park could have the sealant at each handled under one quote.
What your quote should include
- What site paperwork they can supply
- Whether old or failed sealant will be cut out, not overlaid
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS
Site staff or a sealant specialist?
Redoing a failed joint usually costs more than getting it right at the outset, 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.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
