Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Looking after the joints
Once the work is signed off, these steps help:
- Check sealant as part of routine building inspections
- Make sure contractors see the asbestos survey before cutting out old mastic
- Brief cleaning contractors to avoid scourers and blades on sealant
- Report cracked or peeling sealant early
Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet. It’s worth having fans checked while the sealant is fresh.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
About our commercial sealant contractors in St Mary Bourne
A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. The enquiries we see most involve greasy, split joints in a kitchen or tea point and expansion joints with the sealant torn out, across window and door perimeters, movement joints in walls and floors and kitchen worktops and splashbacks. A specialist sealant contractor works differently from a general builder: in St Mary Bourne, that means joint design, primers and backing rod as standard.
If you look after more than one building near St Mary Bourne, the work can be planned as one programme, so standards and paperwork match across every site.
Commercial sealant work around smaller places like St Mary Bourne 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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Cracking that needs a structural engineer to look at it
- Water from a services leak rather than a joint
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
Surfaces we seal
- Window and door perimeters
- Movement joints in walls and floors
- Washrooms and tea points
- External facade joints
- Floor and threshold joints
- Kitchen worktops and splashbacks
Why it’s worth doing now in St Mary Bourne
Leaving a failed joint rarely saves money. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below. Dealing with it while the damage stops at the bead is the cheaper route. Converted and older buildings near places like St Mary Bourne tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why us?
- Our applicators hold CSCS cards
- Joints cleaned back to sound surfaces
- Clear, fixed quotes
- Matching to RAL references, product permitting

Advice
Questions about St Mary Bourne
Is a smaller place like St Mary Bourne outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Can you supply sealant in our brand colour for a site in St Mary Bourne?
Yes, we can usually get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.
Do you work directly for building managers?
Yes. A large share of our work comes through facilities managers, managing agents and landlords. Tell us how you issue work and we’ll fit in.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is failed sealant stripped out, or sealed over?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip; the faces are then cleaned and prepared.
What about asbestos in old mastic?
It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested.
What the job involves on each surface
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. The product depends on whether the joint will be painted, matched to the frame colour where colour matters.
Shop fronts and retail fit-outs
In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, frequently colour-matched to the fit-out. We will confirm the colours available for the specified product.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
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.
