Remedial sealant in Todd's Green
Two decades of sealant work means we recognise most failures quickly. We are ARBOMaster approved and fully insured, and remedial work carries our 12-month guarantee. We are often asked to deal with a second bead peeling off the first and gaps opening along the back of the worktop, across botched or over-sealed joints, mouldy bath & shower sealant and expansion joints.
Being in a small place like Todd's Green 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.
You get a 12-month guarantee, the same in Todd's Green as everywhere else we work.

Remedial sealant around Todd's Green
Todd's Green has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
In the older streets around Church of St Mary the Virgin, walls and floors in older homes can move, and sealant and grout show it first. Managing a site like The John Henry Newman School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Common questions in Todd's Green
Do you work in hotels near Todd's Green?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
I let a flat near Stevenage station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Is it messy?
We keep the work tidy. Nearby surfaces are protected.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Todd's Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

What affects the quote in Todd's Green
Your quote is based on your job. We look at:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- How many areas need sealing
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
Before you ask for a quote, have a think about:
- Where the property is
- Photos by email, if that’s easy
- The rough size of the job
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work.
Do you need remedial sealant in Todd's Green?
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
People usually contact us after spotting one of these:
- Over-sealed joints coming away
- Wide, uneven beads that look worse than the old ones
- Torn expansion joints
- Sealant that came away because the surface wasn’t prepared
If you let a flat or house near Stevenage station, botched sealant from a previous quick fix is easier to strip out between tenants.
Before booking anyone
- How long to leave it before use
- Whether VAT is included
- Which sealant they’ll use, and why
- How the surfaces are prepared before sealing
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Air the bathroom so the sealant can dry
- Clean sealant with mild products only
- Have loose fittings fixed before resealing
- Check ceilings under showers for marks
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
What happens if it’s left?
Remedial work takes longer than a straight reseal, but rarely a lot: it takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. Older cottages and farmhouses around Todd's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we will talk you through it.
