The process
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work normally takes a few hours per area, with larger sites planned over several visits. For a village or hamlet like Sibertswold, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we visit and agree the scope, the sequence and the working hours.
- Room by room, we protect the area and remove all the old sealant.
- Joints are cleaned, treated for mould and dried.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- We check every room and give its cure time for housekeeping.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
How to get a quote

What we’re called out for in Sibertswold
Staff kitchens and food areas see constant splashing and wiping, so sealant there wears and stains. Worktop and sink joints are often the first to go.
Any of these means the joints need attention:
- Water marks on ceilings under bathrooms
- Mouldy washroom sealant that staff and guests notice
- Leaking joints in shower rooms and changing areas
- Sealant failing again soon after quick repairs
If you let a flat or house near Shepherds Well station, sealant work can be quoted for a single flat or a whole portfolio.
Questions to ask before booking

Leave it or put it right?
Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. We will tell you if we find anything that needs another trade. Older cottages and farmhouses around Sibertswold can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What you get with us
- Full insurance on every job
- 20+ years of sealant experience

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep extractor fans working and serviced
- Put a squeegee in each shower
- Use mild cleaners on sealant, not bleach or abrasives
- Keep a record of which rooms were resealed and when
Keep the extraction running and maintained. Where a room has no window, the fan is what dries it out, and mould comes back faster without it.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, and only replacement fixes it.
FAQs for Sibertswold
Is Sibertswold within the area you cover?
Yes, Sibertswold is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Shepherds Well station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can you reseal hotel rooms while we stay open?
Yes. The order and timing are agreed with your team, and you will know when each room can be used.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Is commercial work guaranteed?
Yes, with our one-year guarantee. Regular gentle cleaning and working extraction help the sealant last.
What information do you need?
Tell us what needs doing and where, with photos by email if possible. We will ask anything else we need to know.
How soon can a room be used after resealing?
Plan for around 24 hours, or the cure time we give for that area. A room-by-room programme keeps only a few rooms out at once.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
For landlords and businesses
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for.
If you manage several properties in or around Sibertswold, several properties can go on one quote. Just tell us the addresses and what each one needs.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
