Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Two decades of sealant work means we recognise most failures quickly. We are ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee.

What the job involves on each surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is usually part of the cause. Along with resealing, we will mention if the room needs better ventilation.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned.
Why deal with it now?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out. Around Midhurst, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Why choose Mr Mastic in Midhurst
- A 12-month guarantee on all work
- Anti-fungal silicone where joints get wet
- A choice of colours where the product allows
- Old sealant always removed completely

Midhurst homes and their sealant
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. There are hotels and other places to stay in and around Midhurst. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
For site and facilities teams at buildings such as Midhurst CofE Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the visit works

It normally takes a few hours, depending on how many layers have to come out. In a smaller place like Midhurst, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can old silicone be taken off without scratching the tiles?
Yes. We take our time over removal, especially on acrylic, enamel and uPVC.
Can you reseal a split movement joint?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.

Signs you need remedial sealant in Midhurst
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
People normally contact us after spotting one of these:
- Over-sealed joints coming away
- Torn expansion joints
- Caulk or the wrong sealant used in a wet area
- Sealant peeling off a dusty or damp surface
For an older house near a landmark such as Roman Catholic Church of Divine Motherhood, older homes can move a little, which is hard on rigid grout and tired sealant.
