Remedial sealant in Andover
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. We work on botched or over-sealed joints, leaking tray & enclosure joints and shrunken worktop sealant, and people most often call us about repeat leaks from the same joint and beads that never stuck properly.
Andover mixes older houses with estates built more recently, and bathrooms range from decades-old suites to brand-new ones. Either way, the sealant and grout are usually the first things to fail.
Big or small, you get the same 12-month guarantee.

What else we do in Andover
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Don’t wait for a small gap to become a leak
- Always have old sealant cut out, not covered
- Ask why a joint failed before redoing it
- Report a tray that rocks or a worktop that lifts
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Different surfaces, different methods
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before any new sealant goes on.
Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
What remedial sealant looks like in Andover
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Andover has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
If you let a flat or house near Andover station, a joint that keeps failing is best fixed properly while the property is empty. Homes close to Church of St Mary include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as St John the Baptist Catholic Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

What we do, step by step
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 a typical bath or shower, longer where several layers have been applied. A visit in Andover needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- 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.
- 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
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Andover: your questions answered
Do you take on hotel work around Andover?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
I let a flat near Andover station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Are you insured?
Yes, we are fully insured for every job we do.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Is remedial work guaranteed?
Yes. Every job comes with our 12-month guarantee.
Leave it or put it right?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
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 the work is at height. Your quote takes all of that into account.

Landlord and commercial work in Andover
We also work for property managers and facilities teams in Andover and across Hampshire. We can quote a run of properties together.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
