How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a morning for a small washroom, and a planned programme for bigger sites. Somewhere like Penhurst 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 start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Before we arrive
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- Move anything stored near the joints

Commercial sealant around Penhurst
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For landlords with property near Battle station, we can quote for one property or a whole portfolio of rentals. For buildings such as The Parish Church of St Michael, any kitchen and washrooms need the same sealant care as any other building.

What the job involves on each surface
Rental portfolios
A sound seal protects the property as well as its appearance.
Welfare facilities
Shower rooms in welfare blocks get heavy use and need sound joints. We reseal with anti-fungal sanitary silicone.
Can I do it myself?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
For landlords and businesses
For anyone letting property in or around Penhurst, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and photos by email help.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Failed tanking or loose tiles behind the sealant
- Certifying fire stopping or building compliance
- Extraction that isn’t working, which needs an electrician or ventilation contractor
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

Why act early in Penhurst
Sealant work is quick by the room: the job takes a few hours for a single washroom, longer for a whole building. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Around Penhurst, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep a record of which rooms were resealed and when
- Add sealant to your planned maintenance checks
- Do not leave a failed joint until the next refurbishment
- Encourage users to squeegee shower walls
Keep the extraction running and maintained. Where a room has no window, the fan is what dries it out, and that is what keeps mould away.
A room that cannot be let or used is lost income. Catching faults early means they can be put right in a short window, instead of turning into a leak that closes the room.
