About our remedial sealant in Coleshill
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out. Common call-outs are for a second bead peeling off the first and leaks that keep coming back after resealing, on leaking tray & enclosure joints, mouldy bath & shower sealant and shrunken worktop sealant.
In a village or hamlet like Coleshill, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
A one-year guarantee comes with the work, just as it does everywhere we cover.

FAQs for Coleshill
Is Coleshill within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Amersham station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Are you insured?
Yes. We’re fully insured.
Someone sealed over the old bead. Can you fix it?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many layers have to come out. Somewhere like Coleshill 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.
- We look at how the sealant has failed and check for movement or a leak path.
- 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.
Before we arrive
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

Advice
Different surfaces, different methods
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint is not the cause, we will say so.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and tell you about any damage we find.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep bleach and abrasives off the bead
- Don’t add new sealant on top of old
- Air the bathroom so the sealant can dry
- Look for stains below bathrooms now and then
Do not let anyone seal over it later. Over-sealing is how many remedial jobs start.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.
Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Where a wall is exposed, as many are in small places like Coleshill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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.

- Failed tanking or loose tiles behind the sealant

If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.

Other services in Coleshill
What remedial sealant looks like in Coleshill
Coleshill has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For site and facilities teams at buildings such as Coleshill Church of England Infant 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. Rented homes near Amersham station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. If you live in an older home near Church of All Saints, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
