How we handle remedial sealant in Shellwood Cross
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. We’re often asked to deal with products that weren’t meant for the joint and sealant applied over old sealant that has lifted, across shrunken worktop sealant, failed movement joints and expansion joints.
Homes around Shellwood Cross are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
Our work is backed for twelve months.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The process
We keep the work tidy and contained to the area we are working on. Expect the work to take a few hours, depending on how many layers have to come out, and we tell you how long to leave it before we go. In a small place like Shellwood Cross, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

Advice
Why it’s worth doing now in Shellwood Cross
Another bead over the top won’t fix a failed joint. It cannot bond to what’s underneath, so the leak carries on and there’s now more to remove. In a small place like Shellwood Cross, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What the job involves on each surface
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Clean sealant with mild products only
- Find out why the sealant failed first
- Keep movement joints clear of mortar and paint
- Check trays and worktops do not move
Do not let anyone seal over it later. New silicone doesn’t bond to old, so the old bead should always come out first.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.

Where do you work from?
Mr Mastic is based in Crawley. We cover Shellwood Cross and the rest of Surrey.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
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.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Common problems we fix in Shellwood Cross
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Common reasons people contact us are:
- Sealant peeling off a dusty or damp surface
- Leaks that keep coming back after resealing
- Gaps opening along the back of the worktop
- Over-sealed joints coming away
For landlords with property near Holmwood station, a joint that keeps failing is best fixed properly while the property is empty.
