How we handle remedial sealant in St Albans
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. Typical jobs include mould trapped under a layer of silicone and sealant applied over old sealant that has lifted, on botched or over-sealed joints, failed movement joints and expansion joints.
Alongside its houses and flats, St Albans has offices, shops and places to stay, and their washrooms and staff kitchens need the same attention as any home. The work is the same in both: old material out, joints cleaned and dried, and a fresh, even finish.
All our work is covered by a 12-month guarantee.

Why it’s worth doing now in St Albans
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing normally puts it right. If they’re not, we will tell you. For businesses in St Albans, a room closed because of a leak or mould costs more than the sealant, so it pays to replace failing joints before they get that far.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and send you a clear quote before we start.

DIY sealant or a professional job?
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 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.
What happens on the day
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for a typical bath or shower, longer where several layers have been applied. In central St Albans, parking can be tight, so tell us about driveways, permits or nearby car parks. For flats, mention stairs, lifts and shared entrances as well.
- 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.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Mention any parking rules near the property
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What we’re called out for in St Albans
One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
It’s worth asking for a quote if you see:
- Sealant peeling off a dusty or damp surface
- Floor or wall movement joints that have failed
- A shower that leaks however often it’s resealed
- A second bead peeling off the first
If you look after a building such as Loreto College, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What to look for in a quote
- Is VAT in the price?
- What product goes in the joint
- Who does the work, and how experienced they are
- What the cure time is
What affects the quote in St Albans
Every job gets its own quote. This is what makes a difference:
- Whether the work is at height
- When we can work, for business premises
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
When you call or email, it’s useful to know:
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- How we’d reach the joints
- Pictures of the joints, sent by email

When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Cracks in the fitting rather than the joint
- Older mastics that may need an asbestos check before removal
- A leaking trap, valve or supply pipe
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.

Bathrooms and kitchens in St Albans
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. St Albans has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
In the older streets around Church of St. Peter, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near St Albans station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
