Remedial sealant in Dorney
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you’re dealing with sealant peeling off a dusty or damp surface and sealant applied over old sealant that has lifted, we can help, whatever the surface.
Somewhere as small as Dorney, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

What remedial sealant looks like in Dorney
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to Church of St James include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Burnham station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Managing a site like Western House Academy? 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.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. Somewhere like Dorney 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.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Common questions in Dorney
Do you work for landlords with property near Burnham station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Dorney?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How long will it take to strip and reseal the joint?
Allow a few hours for most joints, depending on how much old sealant has to come out. You will know the timing when we quote.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you strip sealant from an acrylic tray safely?
Yes. We take our time over removal, especially on acrylic, enamel and uPVC.
What happens if it’s left?
Stripping out botched sealant adds time to a reseal, but rarely a lot: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. In a small place like Dorney, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Clean sealant with mild products only
- Never fill a movement joint with mortar or grout
- Act on a lifting corner right away
- Find out why the sealant failed first
Do not let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
What affects the cost of remedial sealant
Your quote is based on your job. We look at:
- The product the joint needs
- The number and length of the joints
- Mould in or behind the old joints
- Working hours on commercial sites
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, phone 0345 464 0079 or send us an email.
