Remedial sealant in Bonnyrigg
Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you have black mould underneath the bead and kitchen joints letting water behind the worktop, we can put it right, whatever the surface.
Around Bonnyrigg, we see everything from older flats to family homes on newer estates. The jobs are much the same in all of them: mouldy beads, gaps where a bath has moved and grout that is cracked or stained.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

Bonnyrigg questions
Is there a guarantee on remedial sealant in Bonnyrigg?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Bonnyrigg for remedial sealant?
Yes, Bonnyrigg is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Where do you work from?
Mr Mastic is based in Crawley. We cover Bonnyrigg and the rest of Midlothian, along with the rest of our area.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.

What we do, step by step
We keep the work tidy and contained to the area we’re working on. Expect the work to take a few hours for a typical bath or shower, longer where several layers have been applied, and we tell you how long to leave it before we go. For a job in Bonnyrigg, tell us where the work is, how to get in and where to park. Outdoor jobs need a dry day, so they can move if the weather turns.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
How to get a quote

Bathrooms and kitchens in Bonnyrigg
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. Mould is another matter: a bathroom that stays damp still turns sealant and grout black. Private landlords in Scotland must be registered and 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.
Managing a site like Lasswade High School Centre? Then we reseal washrooms and kitchens in schools and businesses as well as homes. If you live in an older home near Bonnyrigg Parish Church, older homes can move a little, which is hard on rigid grout and tired sealant.

When to call us in Bonnyrigg
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:
- Kitchen joints letting water behind the worktop
- A shower that leaks however often it’s resealed
- Sealant that came away because the surface wasn’t prepared
- Smears and lumps from a botched reseal
For landlords with property near Eskbank station, a joint that keeps failing is best fixed properly while the property is empty.

When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- A bath, tray or worktop that moves until it’s properly fixed
- A tray or bath that is cracked
- Plumbing leaks behind walls or under trays
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Failed movement joints

Surface by surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. We strip it back so we can see the joint.
What affects the quote in Bonnyrigg
Call for a quick quote. What matters most is:
- Access and height
- Working hours on commercial sites
- How much there is to do
- Mould in or behind the old joints
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- Any previous sealing or DIY work
- Roughly how big the job is
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Why it’s worth doing now in Bonnyrigg
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Scottish weather finds any gap, and in a town like Bonnyrigg, failed outside joints soon let damp into walls. Indoors, failed sealant lets water into floors and ceilings.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Why us?
- Anti-fungal sanitary silicone in wet areas
- Quality sealants from Arbo and Everbuild
- ARBOMaster approved applicator
- We leave the area clean and tidy
See our cost guide or what customers say.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
