How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours per room, so whole buildings are phased. Somewhere like Underling Green 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.
- First we visit and agree the scope, the sequence and the working hours.
- Each area is protected and the old sealant cut out completely.
- We clean the joints, treat any mould and let them dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work

Leave it or put it right?
Refitting a washroom is a big, disruptive project. When the fittings are sound, renewing the sealant brings it back with far less upheaval. If something else is wrong, we’ll say so. Around Underling Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

What sealant work cannot fix
To be straight with you, there are a few things sealant will not fix:
- Tiles coming off the wall
- Extraction that isn’t working, which needs an electrician or ventilation contractor
- Water coming from plumbing rather than sealant
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What affects the quote in Underling Green
Every job gets its own quote. This is what makes a difference:
- Mould in or behind the old joints
- Whether the work is at height
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
What we need to know
There’s no need for technical detail. Just tell us:
- Any access issues, like height or stairs
- A few photos by email, if you can
- What’s wrong with the joints now
- How many joints, rooms or windows are involved

Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
How soon can a room be used after resealing?
It depends on the product, but around 24 hours is typical. Housekeeping get the cure time for each room.

Yes. For several properties, we can plan the work as one programme.
