Why act early in Apsley
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. In a smaller place like Apsley, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email and we will talk you through it.

Remedial sealant in Apsley
Remedial jobs in Apsley usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. We work on shrunken worktop sealant, leaking tray & enclosure joints and expansion joints, and the jobs we see most are products that weren’t meant for the joint and worktop sealant that has shrunk and split.
In and around Apsley, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Apsley homes and their sealant
Apsley is part of Hemel Hempstead, one of the post-war new towns. Many homes date from the post-war decades, so bathrooms and kitchens may be on their second or third set of sealant. New sealant will not stick to old, so the old layers have to come out first. 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.
For site and facilities teams at buildings such as Two Waters Primary School, 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.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied and we leave things clean and tidy. Parking around Apsley is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- 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 access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
- Move anything stored near the joints

What affects the quote in Apsley
The quote reflects the job in front of us. We take into account:

What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Surface by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out.
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
What we are called out for in Apsley
Movement tears sealant that isn’t designed for it. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
Keep an eye out for these signs:
- Mould trapped under a layer of silicone
- Gaps opening along the back of the worktop
- Wide, uneven beads that look worse than the old ones
- Sealant applied over old sealant that has lifted
If you let a flat or house near Apsley station, botched sealant from a previous quick fix is easier to strip out between tenants.

Questions from Apsley
Is Apsley within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it worth replacing old sealant in an older home in Apsley?
In most cases, yes, if it hasn’t been done for a while. Sealant doesn’t last for ever, and its life depends on use, cleaning and weather.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
What information do you need?
Tell us what needs doing and where. We will ask anything else we need to know.
Can old silicone be taken off without scratching the tiles?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep an eye on the ceiling below the bathroom
- Act on a lifting corner straight away
- Check trays and worktops do not move
- Don’t point over movement joints
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, call 0345 464 0079 or send us an email.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
