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. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Remedial sealant in Piccotts End
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out before the joint can be done properly. We’re often asked to deal with gaps opening along the back of the worktop and black mould underneath the bead, on mouldy bath & shower sealant, leaking tray & enclosure joints and botched or over-sealed joints.
For a small place like Piccotts End, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
Whatever the size of the job, you get the same one-year guarantee in Piccotts End and across Hertfordshire.

The process
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. For a village or hamlet like Piccotts End, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Advice
Piccotts End: your questions answered
I let a flat near Hemel Hempstead station. Can you help?

Is Piccotts End within the area you cover?
Yes, Piccotts End is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Can failed expansion joints be resealed?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Is remedial work guaranteed?
Yes. Our one-year guarantee covers the work, and we are ARBOMaster approved.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Surface by surface
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, so the sealant grips the two sides only.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Remedial sealant in Piccotts End: local notes
Hemel Hempstead, which Piccotts End is part of, is one of England’s 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. Sealant laid over old sealant never bonds properly, so it all has to come out. 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.
For an older house near a landmark such as St Mary's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Hemel Hempstead station, a joint that keeps failing is best fixed properly while the property is empty.

Signs you need remedial sealant in Piccotts End
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Any of these means the joints need attention:
- Floor or wall movement joints that have failed
- A second bead peeling off the first
- Kitchen joints letting water behind the worktop
- Repeat leaks from the same joint
For site and facilities teams at buildings such as Galley Hill Primary School and Nursery, 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.
What your quote should include
- Whether you can choose the colour
- Whether they’re fully insured
