Remedial sealant in Great Leighs, done properly

Being in a small place like Great Leighs makes no difference to the job itself: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.

Why act early in Great Leighs
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a small place like Great Leighs, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

FAQs for Great Leighs
Will you come out to Great Leighs?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Cressing station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
What should I tell you?
A short description and the location, plus pictures if you have them. We will ask anything else we need to know.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Are you insured?
Yes. We are fully insured for every job we do.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
What we’re called out for in Great Leighs
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Any of these means the joints need attention:
- A second bead peeling off the first
- Smears and lumps from a botched reseal
- Beads that never stuck properly
- Torn expansion joints
For landlords with property near Cressing station, botched sealant from a previous quick fix is easier to strip out between tenants.
What your quote should include
- How long the guarantee is
- Whether you can choose the colour
- Are they insured?
- Is the old sealant removed completely?

How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- How much there is to do
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Any access issues, like height or stairs
- Roughly how big the job is
- A few pictures by email, if you can
- Whether it has been sealed before

Honest limits
Before booking, it’s worth knowing the limits too:
- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
- A tray or bath that’s cracked
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Failed movement joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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 remedial sealant looks like in Great Leighs
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as Church of St John the Evangelist, older homes can move a little, which is hard on rigid grout and tired sealant. Managing a site like Great Leighs Primary School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
