The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a morning for a small washroom, and a planned programme for bigger sites. In a London area like Seven Sisters, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

What we are called out for in Seven Sisters
Quick fixes come back quickly. Sealing over old silicone, sealing wet joints or using the wrong product all lead to the same thing: another reseal before long.
It’s worth asking for a quote if you see:
- Washrooms that need sorting before an inspection
- Sealant failing again soon after quick repairs
- Water marks on ceilings under bathrooms
- Whole floors of tired en suites
If you look after a building such as Earlsmead Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Add sealant to your planned maintenance checks
- Use mild cleaners on sealant, not bleach or abrasives
- Keep a record of which rooms were resealed and when
- Check extract fans are actually running
Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and mould comes back faster without it.
Signs to look for: mould, splits, peeling corners or water marks downstairs. Any of these means the joints need attention.
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
How we quote for commercial sealant
For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- The number of rooms or windows
- The old material and how stubborn it is
- The amount of work
Every job is a little different, 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 to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- The address or postcode of the job
- Pictures of the joints, sent by email
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.
