Remedial sealant in Newbigging, done properly
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 need stripping out. If you’re dealing with thick, messy sealant smeared over tiles and floor or wall movement joints that have failed, we can put it right.
Bathrooms in smaller places like Newbigging work just as hard as those in the cities. Generally soft Scottish water means less limescale, but steam still lets mould into sealant and grout.
Whatever the size of the job, you get the same one-year guarantee in Newbigging and across Dundee.

Different surfaces, different methods
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. We will reseal and tell you if extraction looks to be the issue.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, and we will tell you if we find it.
Do you need remedial sealant in Newbigging?
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
The most common problems we see are:
- Over-sealed joints coming away
- Beads that never stuck properly
- Black mould underneath the bead
- Torn expansion joints
Rented homes near Monifieth station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many layers have to come out and we leave things clean and tidy. Outside jobs in Newbigging need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- 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.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

What affects the quote in Newbigging
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether the work is at height
- Whether there’s mould to deal with
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Helping us quote
What to tell us when you ask for a quote:
- The address or postcode of the job
- The type of property
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Run the fan after every shower
- Find out why the sealant failed first
- Keep an eye on the ceiling below the bathroom
- Act on a lifting corner right away
Keep the room ventilated: use the extractor or open a window after showering.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
What remedial sealant looks like in Newbigging
Newbigging is within about 3 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Dundee has plenty of sandstone tenements, where a failed bath or shower seal can reach the flat below.
In the older streets around Newbigging Parish Church And War Memorial, older homes can move a little, which is hard on rigid grout and tired sealant.

What else we do in Newbigging
Leave it or put it right?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. Around Newbigging, water from a failed joint in an older stone home can soak into timber and plaster.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
