Remedial sealant & repairs in Iffley, Oxfordshire
Failed sealant joints in Iffley need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.

- Thick, messy sealant smeared over tiles
- Caulk or the wrong sealant used in a wet area
Remedial sealant for homes and businesses in Iffley
Some sealant jobs aren’t a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out before the joint can be done properly. If you are dealing with leaks that keep coming back after resealing and decorators’ caulk around a bath or shower, we can put it right, on botched or over-sealed joints, mouldy bath & shower sealant and leaking tray & enclosure joints alike.
Even in a smaller place like Iffley, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: all the old material out, the joint cleaned and dried, then new sealant or grout.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

Iffley: your questions answered
Do you work for landlords with property near Oxford station?

Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
What remedial sealant looks like in Iffley
Iffley has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Rented homes near Oxford station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. In the older streets around Church of St James, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What affects the quote in Iffley
Every job gets its own quote. These are the things that affect it:
- Which sealant suits the joint
- The old material and how stubborn it is
- Access and height
- How many areas need sealing
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
You do not need to know the technical terms. Just tell us:
- A few pictures by email, if you can
- The problem you’ve noticed
- The address or postcode of the job
- Whether it has been sealed before
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved.
When to call us in Iffley
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.
These are the problems we are asked about most:
- Repeat leaks from the same joint
- Decorators’ caulk around a bath or shower
- Sealant peeling off a dusty or damp surface
- Worktop sealant that has shrunk and split
For site and facilities teams at buildings such as Rose Hill Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
Before booking anyone
- Who turns up on the day
- Which colour the sealant will be
- How hidden problems are handled
- Whether the sealant suits the joint
Looking after it afterwards
So the new joints stay in good condition:
- Keep movement joints clear of mortar and paint
- Don’t wait for a small gap to become a leak
- Look for stains below bathrooms now and then
- Use a soft cloth, not a scourer, on silicone
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. If anything changes, just phone 0345 464 0079 or email us.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
Why act early in Iffley
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing usually puts it right. If they’re not, we’ll tell you. Around Iffley, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.
Why us?
- White, clear, grey or coloured to suit, where the product allows
- Experience in homes, commercial sites and hotels
- Fully insured
- We agree the colour with you first

What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours, depending on how many layers have to come out from start to finish. In a smaller place like Iffley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any tricky access
- Keep pets and children clear of the area while we work

What the job involves on each surface
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
