How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere like Sandford St Martin needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on

Advice
About our remedial sealant in Sandford St Martin
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. We work on leaking tray & enclosure joints, expansion joints and shrunken worktop sealant, and people most often call us about products that weren’t meant for the joint and sealant that came away because the surface wasn’t prepared.
Being in a small place like Sandford St Martin makes no difference to the job itself: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
A one-year guarantee comes with the work, just as it does everywhere we cover.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Your questions about remedial sealant in Sandford St Martin
Can you do remedial sealant in Sandford St Martin?
Yes. Our work covers London and the South East, and Sandford St Martin is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is Sandford St Martin within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What should I tell you?
A short description and the location. We’ll ask anything else we need to know.
Are you insured?
Yes. Full insurance covers our work.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is remedial work guaranteed?
Yes. Our one-year guarantee covers the work, and we are ARBOMaster approved.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Never fill a movement joint with mortar or grout
- Never seal over old silicone
- Do not wait for a small gap to become a leak
- Check trays and worktops don’t move
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, ring 0345 464 0079 or send us an email.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Signs you need remedial sealant in Sandford St Martin
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
People generally contact us when they notice one of these:
- Smears and lumps from a botched reseal
- Caulk or the wrong sealant used in a wet area
- Sealant that came away because the surface wasn’t prepared
- Black mould underneath the bead
Rented homes near Heyford station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.
What to look for in a quote
- What insurance they hold
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
- What happens if they find a problem under the old sealant
Why it’s worth doing now in Sandford St Martin
Another bead over the top won’t fix a failed joint. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. In a small place like Sandford St Martin, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
