Remedial sealant in Dolphinton, done properly
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you drop us a line at info@mrmastic.co.uk, and say how long ago it was last done. We’re often asked to deal with sealant that came away because the surface wasn’t prepared and floor or wall movement joints that have failed, on shrunken worktop sealant, expansion joints and mouldy bath & shower sealant.
Being further from a city does not change the work: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. We just plan the journey and access beforehand.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Aftercare tips
Looking after new joints is easy:
- Ask why a joint failed before redoing it
- Always have old sealant cut out, not covered
- Clean sealant with mild products only
- Keep the room well ventilated
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
What the job involves on each surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. We rake that out where it can be removed and seal with a flexible product.
Windows & doors
Some leaks around windows come from the wall or the window itself. If the frame joint isn’t the cause, we will say so.
The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- 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.
Before we arrive
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

Advice
Dolphinton questions
Do you cover smaller places like Dolphinton?
Yes. Dolphinton is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is remedial sealant in Dolphinton guaranteed?
All our work, in Dolphinton and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
How much does remedial sealant cost in Dolphinton?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
How long will it take to strip and reseal the joint?
Allow a few hours for most joints, depending on how much old sealant has to come out. You will know the timing when we quote.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
How we quote for remedial sealant
Call for a quick quote. The main things that affect it are:
- How many areas need sealing
- When we can work, for business premises
- How easy the joints are to reach
- Mould in or behind the old joints
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The address or postcode of the job
- Any access issues, like height or stairs
- If someone has resealed it before
- How many joints, rooms or windows are involved
We quote each job on its own, so start by telling us what you need. Simply drop us a line at info@mrmastic.co.uk and describe the job and send pictures if you have them.
When to call us in Dolphinton
Movement tears sealant that is not designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that’s too stiff or too thin.
Signs it’s time to call us include:
- Black mould underneath the bead
- Repeat leaks from the same joint
- Torn expansion joints
- Thick, messy sealant smeared over tiles
In and around Dolphinton, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.
Before you book anyone

- The length of the guarantee
- Which sealant they’ll use, and why
- Is the old sealant removed completely?
Remedial sealant around Dolphinton
Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that doesn’t dry out. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
Homes close to Dolphinton Parish Church And Churchyard include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In an older home around Dolphinton, damp from a failed joint can get into timber and plaster.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
