Floor joint sealing for homes and businesses in Ninewells
Every floor moves a little, so its edges need a joint that can flex. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed. We work on skirting boards, concrete floor joints and wet room & bathroom floors, and people most often call us about perimeter joints in tiled floors filled with grout and failed joint filler in concrete floors.
Older tenement flats generally have timber floors on joists, so skirting joints open and close through the year. In Ninewells, a flexible sealant suits those joints better than filler.
All of our work is guaranteed for twelve months, in Ninewells and everywhere else we cover.

What happens on the day
Before we leave, we go over the finished joints with you. The visit itself usually takes a morning or an afternoon for most homes, depending on the size of the job. In a city area like Ninewells, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children

What we’re called out for in Ninewells
New floors settle once they’re in use. The edges pull away from the skirting and anything rigid cracks.
It’s worth asking for a quote if you see:
- Rigid edge joints in tiled floors
- Dirt and water collecting in open floor joints
- Grout cracking in a straight line across a floor
- Cracked caulk along skirting in bathrooms and kitchens
Schools such as Menzieshill High School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
How we quote for floor joint sealing
For a quick quote, just ask. What matters most is:

The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

What to tell us when you ask for a quote:
- How we’d reach the joints
- Any previous sealing or DIY work

Questions from Ninewells
Is Ninewells in your area for floor joint sealing?
Yes, Ninewells is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Is there a guarantee on floor joint sealing in Ninewells?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
How long before the joint can take traffic?
Follow the cure time we give you. Feet are generally fine first, then mopping, then heavy wheels in most cases.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Can grout be replaced with sealant on a tiled floor?
Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
New homes and floors in Ninewells
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. Across Dundee, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal.
For landlords with property near Invergowrie station, gaps at skirtings and thresholds are worth sealing between tenancies.

What happens if it’s left?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant stretches instead and keeps the joint sealed. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Ninewells, damp can travel a long way before it shows.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Do not paint over silicone
- Mark off resealed joints in warehouses
- Check skirting joints after the heating season
- Get cracks along tile grout lines looked at early
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up early on.
Small gaps are quick to seal. Left alone, they collect dirt and widen.
When it is not the sealant
Before you book, it’s worth knowing the limits:
- Large cracks that need a surveyor
- Cracked or broken concrete slabs
- Floors that are uneven or need levelling
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.
