Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
There’s no need for technical detail. Just tell us:
- If someone has resealed it before
- Access, such as stairs, a lift or height
- Where the property is
- A few photos by email, if you can

Remedial sealant in Tyttenhanger
The wrong product in the wrong joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. Typical jobs include dark patches showing through the sealant and decorators’ caulk around a bath or shower, across leaking tray & enclosure joints, botched or over-sealed joints and failed movement joints.
Around Tyttenhanger, it’s houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
Your job is guaranteed for a year, as with all our work.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on how much there is to do. For a village or hamlet like Tyttenhanger, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- 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.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

What the job involves on each surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces before backing and resealing.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Your questions about remedial sealant in Tyttenhanger
Is Tyttenhanger within the area you cover?
Yes, Tyttenhanger is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can failed expansion joints be resealed?

Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Find out why the sealant failed first
- Have loose fittings fixed before resealing
- Look for stains below bathrooms now and then
- Never seal over old silicone
Leave the new joint to cure fully before it gets wet or moves: normally around 24 hours, or as long as we advise.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
Signs you need remedial sealant in Tyttenhanger
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
If you can see any of these, it’s time to have the joints looked at:
- Beads that never stuck properly
- Wide, uneven beads that look worse than the old ones
- Torn expansion joints
- A shower that leaks however often it’s resealed
For landlords with property near St Albans station, botched sealant from a previous quick fix is easier to strip out between tenants.

Remedial sealant around Tyttenhanger
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.
Schools such as Nicholas Breakspear School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of St Mark include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

What we can’t put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Failed tanking or loose tiles behind the sealant
- Movement from fittings that aren’t supported
