What the job involves on each surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, including the screen profile and tray edges.
How we handle remedial sealant in Allen's Green
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. We work on mouldy bath & shower sealant, botched or over-sealed joints and leaking tray & enclosure joints, and people most often call us about smears and lumps from a botched reseal and dark patches showing through the sealant.
Around Allen's Green, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Signs you need remedial sealant in Allen's Green
Products get mixed up: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.
If you can see any of these, it’s time to have the joints looked at:
- Thick, messy sealant smeared over tiles
- Decorators’ caulk around a bath or shower
- A second bead peeling off the first
- Worktop sealant that has shrunk and split
For landlords with property near Sawbridgeworth station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Before you book anyone

- How the joint is cleaned and prepared

- What happens if the job turns out different
Leave it or put it right?
Ripping out a bathroom isn’t normally needed. If the bath, tray and tiles are sound, remedial resealing generally puts it right. Where something else has failed, you’ll hear it from us. Around Allen's Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
What you get with us
- Anti-fungal sanitary silicone in wet areas
- 20+ years of sealant experience
- We leave the area clean and tidy
- We agree the colour with you first
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied and we leave things clean and tidy. For a village or hamlet like Allen's Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any tricky access
- Try not to wet indoor joints just before the visit

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What remedial sealant looks like in Allen's Green
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Former Church of St Anne, walls and floors in older homes can move, and sealant and grout show it first.
