Northfield: your questions answered
Do you work for hotels and guest houses in Northfield?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
I let a flat near Brunstane station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Does remedial work come with a guarantee?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
Can you take off two layers of silicone?
Yes. We remove every layer; over-sealing fails because silicone will not bond to silicone.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Remedial sealant in Northfield
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We work on expansion joints, failed movement joints and mouldy bath & shower sealant, and common reasons people get in touch are beads that never stuck properly and leaks that keep coming back after resealing.
Stone-built tenements are part of every Scottish city, alongside suburban houses and modern blocks. With flats above and below, a leak from a tired seal can reach the flat underneath, and that is as true in Northfield as anywhere in the city.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Quotes for remedial sealant in Northfield
We don’t publish a price list, because jobs vary so much. What we look at:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- Any mould that needs treating
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- The rough size of the job
- The type of property
- The address or postcode of the job
- What’s wrong with the joints now
For remedial sealant in Northfield, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep the room well ventilated
- Use a soft cloth, not a scourer, on silicone
- Keep an eye on the ceiling below the bathroom
- Do not wait for a small gap to become a leak
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old, so the old bead should always come out first.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.
Landlord and commercial work in Northfield
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Cracks in the fitting rather than the joint
- Movement from fittings that are not supported
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.

How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for most joints, depending on how much old sealant has to come out. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Northfield, it helps to know the floor, the door entry arrangements and the nearest parking.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
Ask for a quote
Getting a quote is simple: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll take it from there.
Advice
What the job involves on each surface
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out so the new sealant starts clean.
Remedial sealant in Northfield: local notes
Northfield is within about 2 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. 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.
If you look after a building such as Portobello High School, 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. Rented homes near Brunstane station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. In the older streets around Willowbrae Parish Church, older homes can move a little, which is hard on rigid grout and tired sealant.
