Commercial mastic work in Stone Street
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. Most enquiries involve window and door perimeter joints that have cracked open and water staining near frames, panels or ceilings, across movement joints in walls and floors, external facade joints and washrooms and tea points. For commercial sealant work in Stone Street, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A lot of what we do in Stone Street is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
A job in a smaller place like Stone Street is typically a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Questions we are asked in Stone Street
Can you match sealant colours for premises in Stone Street?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.
Is Stone Street too far out for you?
Not at all. Stone Street is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you supply RAMS and insurance details?
We confirm documents at quote stage: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.
How many days will you need on site?
It depends on the scope, but the work usually takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you work for facilities managers and managing agents?
Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.
How is commercial sealant work priced?
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.
Is the old sealant taken out first?
Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts.
How the job changes by surface
Washrooms and toilets
Mould that has grown into washroom sealant can’t usually be cleaned out. The lasting answer is removal, preparation and a new sanitary bead, room by room if that suits the building.
Facade and cladding joints
Facade joints move every day as panels warm and cool. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Keep barriers up until the new sealant has cured
- Ask fit-out and M&E contractors to report any sealant they disturb
- On pre-2000 buildings, share the asbestos information before work starts
- Log reseals in the O&M or maintenance records
New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth, and we confirm it when each area is handed back. Keeping signs or barriers up until then protects the finish.
Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- A dripping trap, valve or pipe behind a fitting
- Old mastic that tests positive for asbestos
- Broken glass or blown double-glazed units
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

- Movement joints in walls and floors
- Window and door perimeters
Common problems we fix in Stone Street
In wet areas the enemy is typically mould rather than movement. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant; when mould is in the body of the sealant, no cleaner will shift it. The fix is a new bead of anti-mould sanitary silicone.
Typical triggers for a call:
- Earlier reseals applied straight onto the failed bead
- Sanitary sealant that has gone black and patchy
- Untidy joints in a reception, shop floor or lobby
- Frame mastic that has hardened and come away from the wall
If you have premises on more than one site, say at Chaucer Business Park and Bourne Enterprise Centre, one contractor and one quote can cover both.
What to look for in a quote
- Their approach to joint depth and backing
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
- What the guarantee covers, and for how long
When to bring in a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
