Remedial sealant in Greosabhagh
The wrong product in the wrong joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We work on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints, and people most often call us about products that weren’t meant for the joint and floor or wall movement joints that have failed.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
Big or small, it’s backed by our one-year guarantee.

Bathrooms and kitchens in Greosabhagh
Greosabhagh is within about 1 mile 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. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
Whether the job is in Greosabhagh itself or nearby, the right material for each joint matters as much as a neat finish.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours, depending on how many layers have to come out. Outdoor work around Greosabhagh depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- 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.
- You get the cure time and our view on why the joint failed.
How to prepare
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Advice
Do you need remedial sealant in Greosabhagh?
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould. At that point it has to come out.
It’s worth asking for a quote if you see:
- Dark patches showing through the sealant
- Thick, messy sealant smeared over tiles
- Sealant peeling off a dusty or damp surface
- Kitchen joints letting water behind the worktop
In and around Greosabhagh, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Can failed expansion joints be resealed?

Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
How much does remedial sealant cost in Greosabhagh?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.

Can I do it myself?
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 does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What the job involves on each surface
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we will say so.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Check ceilings under showers for marks
- Use a soft cloth, not a scourer, on silicone
- Never fill a movement joint with mortar or grout
- Don’t add new sealant on top of old
If the joint ever needs renewing, have it cut out, not sealed over. New silicone does not bond to old.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into floors, walls or ceilings. Early action keeps it to a sealant job.
