Remedial sealant for homes and businesses in Penicuik
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we’ll tell you rather than reseal something that won’t fix it. If you have leaks that keep coming back after resealing and worktop sealant that has shrunk and split, we can help.
Around Penicuik, we see everything from older flats to family homes on newer estates. In every one, the usual problems are mould in the bead, gaps where things have moved and tired grout.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

What remedial sealant looks like in Penicuik
There are hotels and other places to stay in and around Penicuik. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out.
Around Penicuik, as everywhere, remedial sealant is only as good as the preparation behind it.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
What we can’t put right
It helps to know what we can’t do too:
- Tiles that have come away from the wall
- A cracked shower tray or bath (that needs repair or replacing)
- A tray or worktop that needs refixing first
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.
Surfaces we seal
- Expansion joints
- Failed movement joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Shrunken worktop sealant
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours for most joints, depending on how much old sealant has to come out. In a Scottish town like Penicuik, parking is usually straightforward, though older centres can be tighter. For flats, mention the shared stair or door entry system.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
How to prepare
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

Do you need remedial sealant in Penicuik?
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.
Most people get in touch when they notice one of these:
- A shower that leaks however often it’s resealed
- Floor or wall movement joints that have failed
- Sealant applied over old sealant that has lifted
- Caulk or the wrong sealant used in a wet area
Managing a site like Beeslack Community High School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
What your quote should include

How we quote for remedial sealant
Every job gets its own quote. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- When we can work, for business premises
- The type of sealant required
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Whether it’s a home or a business
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
Why it’s worth doing now in Penicuik
Another bead over the top will not fix a failed joint. It does not grip the old layer, so the leak carries on and there’s now more to remove. In Penicuik, wind and rain soon get through failed outside joints. Indoors, failed sealant lets water into floors and ceilings.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.
