St Ippolyts Remedial Sealant
We cover St Ippolyts for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- Torn expansion joints
- Sealant peeling off a dusty or damp surface
- Over-sealed joints coming away
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Remedial sealant in St Ippolyts
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. Common call-outs are for kitchen joints letting water behind the worktop and leaks that keep coming back after resealing, across failed movement joints, expansion joints and botched or over-sealed joints.
Somewhere as small as St Ippolyts, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Big or small, it’s backed by our 12-month guarantee.

Common questions in St Ippolyts
I let a flat near Hitchin station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Do you work for hotels and guest houses in St Ippolyts?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you remove old sealant without damaging the bath?
Yes. We take our time over removal, especially on acrylic, enamel and uPVC.
What should I tell you?
Let us know what needs doing and where, plus pictures if you have them. If we need more, we will ask.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
How long should I leave it?
It depends on the product. Before we leave, we’ll tell you the cure time.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How do I get a quote for remedial sealant in St Ippolyts?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
How it works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours, depending on how many layers have to come out from start to finish. For a village or hamlet like St Ippolyts, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
Getting a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or drop us an email.
Advice
What happens if it’s left?
Ripping out a bathroom isn’t generally needed. If the bath, tray and tiles are sound, remedial resealing normally puts it right. Where something else has failed, you will hear it from us. Around St Ippolyts, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What we are called out for in St Ippolyts
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
Signs it’s time to call us include:
- Repeat leaks from the same joint
- A second bead peeling off the first
- Torn expansion joints
- Black mould underneath the bead
Homes close to Church of St Ippolyts (church of England) include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- Whether they’re fully insured
- How the joint is cleaned and prepared
- How much experience the applicator has
- How long to leave it before use
What affects the cost of remedial sealant
We don’t publish a price list, because no two jobs are the same. What we look at:
- The product the joint needs
- How many areas need sealing
- Whether there’s mould to deal with
- How much there is to do
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Where the property is
- The type of property
- Photos by email, if that is easy
- Any access issues, like height or stairs
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we will come back to you with a quote.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Do not wait for a small gap to become a leak
- Keep movement joints clear of mortar and paint
- Check ceilings under showers for marks
- Get the cause of a repeat leak found before resealing
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.

What the job involves on each surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
