Remedial sealant for homes and businesses in Dunsden Green
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. We work on failed movement joints, botched or over-sealed joints and mouldy bath & shower sealant, and the jobs we see most are dark patches showing through the sealant and smears and lumps from a botched reseal.
Homes around Dunsden Green are mostly houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
All our work is covered by a 12-month guarantee.

What affects the cost of remedial sealant
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- Which sealant suits the joint
- The size of the job
- The number of rooms or windows
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
When you contact us, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
- If someone has resealed it before
- The type of property
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, call 0345 464 0079 or drop us an email.
Common problems we fix in Dunsden Green
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
These are the problems we are asked about most:
- Leaks that keep coming back after resealing
- Kitchen joints letting water behind the worktop
- Sealant applied over old sealant that has lifted
- Torn expansion joints
In the older streets around All Saints Church, walls and floors in older homes can move, and sealant and grout show it first.
What to look for in a quote
- Is the old sealant removed completely?
- Whether you can choose the colour
- How the joint is cleaned and prepared
- Are they insured?
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, 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
How long the joints last depends on use and care. Here’s what we suggest:
- Check trays and worktops don’t move
- Run the fan after every shower
- Keep bleach and abrasives off the bead
- Do not wait for a small gap to become a leak
Give the new sealant its full cure time: follow the cure time we give you.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
Why it’s worth doing now in Dunsden Green
Ripping out a bathroom isn’t normally needed. If the bath, tray and tiles are sound, remedial resealing usually puts it right. Where something else has failed, you will hear it from us. Older cottages and farmhouses around Dunsden Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Why book with us
- Any old sealant cut out fully, not covered over
- Trusted Arbo and Everbuild sealants

What the job involves on each surface
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Questions from Dunsden Green
Do you work for landlords with property near Reading station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can you do remedial sealant in Dunsden Green?
Yes. We work across London and the South East, and Dunsden Green is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
What happens if the problem is the tray or the plumbing?
You will hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we will not pretend it will.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. We’ll ask anything else we need to know.
