About our remedial sealant in Langley Bottom
In Langley Bottom, as anywhere, remedial jobs tend to look alike: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. We work on leaking tray & enclosure joints, botched or over-sealed joints and mouldy bath & shower sealant, and the jobs we see most are floor or wall movement joints that have failed and gaps opening along the back of the worktop.
Somewhere as small as Langley Bottom, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Every job comes with our one-year guarantee.

Leave it or put it right?
Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Around Langley Bottom, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Quotes for remedial sealant in Langley Bottom

- When we can work, for business premises
- The number and length of the joints
- Which sealant suits the joint
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What to tell us when you ask for a quote:
- Where the property is
- Whether it has been sealed before

Surface by surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom.
Langley Bottom homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Rented homes near Stevenage station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. Schools such as The Thomas Alleyne School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

The process
When we get to you, 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 few hours for most joints, depending on how much old sealant has to come out. Somewhere like Langley Bottom needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Langley Bottom: your questions answered
Is Langley Bottom within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Stevenage station. Can you help?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can you remove old sealant without damaging the bath?
Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. Any existing damage is pointed out before we start.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Langley Bottom, along with the rest of our area.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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.
