Remedial sealant in Marshalswick, done properly
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and remedial work carries our one-year guarantee. We work on failed movement joints, leaking tray & enclosure joints and botched or over-sealed joints, and people most often call us about movement joints that have split or pulled away and wide, uneven beads that look worse than the old ones.
Smaller places like Marshalswick still have plenty of bathrooms that work hard every day. Older or newer, every room gets the same approach: all the old material out, the joint cleaned and dried, then new sealant or grout.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Remedial sealant around Marshalswick
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
In the older streets around Saint Mary's, walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near St Albans station, botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like St John Fisher Roman Catholic Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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.
Surface by surface
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
What affects the quote in Marshalswick
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- Mould in or behind the old joints
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email and we’ll talk you through it.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- How we’d reach the joints
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved and send you a clear quote.
Landlord and commercial work in Marshalswick
If you manage several properties in or around Marshalswick, several properties can go on one quote. Just tell us the addresses and what each one needs.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Find out why the sealant failed first
- Always have old sealant cut out, not covered
- Look for stains below bathrooms now and then
- Report a tray that rocks or a worktop that lifts
Keep the room ventilated: use the extractor or open a window after showering.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.
Marshalswick: your questions answered
Do you cover smaller places like Marshalswick?
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.
Is Marshalswick in your area for remedial sealant?
Yes. We work across London and the South East, and Marshalswick is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Do you work for landlords and businesses?
Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Why it’s worth doing now in Marshalswick
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. It’s far less disruption than resealing the same joint again and again. Homes in smaller places like Marshalswick can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- Experience in homes, commercial sites and hotels
- Old sealant always removed completely
- Over 20 years’ experience
- White, clear, grey or another colour, product permitting

How the visit works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. For a job in Marshalswick, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Mention any tricky access
