Why it’s worth doing now in Penicuik
Regrouting a cracked line in a tiled floor rarely fixes it. The movement is still there, so the grout fails again. Replacing that line with flexible sealant gives it somewhere to go. If you live in a flat in Penicuik, failed sealant can send water to the neighbours below, and that is much harder to put right.

Floor joint sealing for homes and businesses in Penicuik
Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant coloured to suit the grout. We work on thresholds, tiled floors and skirting boards, and common reasons people get in touch are open joints that fill with dirt and failed seals where bathroom floors meet baths and panels.
Around Penicuik, shops and business units have floor joints that break down under traffic. Sealing them before the edges break up saves a bigger repair.
Your job is guaranteed for a year, as with all our work.

Joints and finishes in Penicuik homes
Floors around Midlothian run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
Schools such as Beeslack Community High School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. In and around Penicuik, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint.

How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for most rooms, longer for large commercial floors. Parking around Penicuik is rarely difficult, though older streets in the centre can be tight. For flats, mention the shared stair or door entry system.
- We look at the gap and the floor type and agree the right sealant.
- Old caulk, grout or sealant is removed from the joint.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- The sealant goes in, chosen for the floor and coloured to suit it.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Advice
What affects the cost of floor joint sealing
We don’t publish a price list, because jobs vary so much. The quote depends on:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- The amount of work
- Working hours on commercial sites
Doing several joints on one visit is generally more efficient than separate visits. We will give you a clear quote for the lot.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The type of property
- Where the property is
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Penicuik questions
What guarantee comes with floor joint sealing in Penicuik?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
How do I get a quote for floor joint sealing in Penicuik?
The easiest way is to drop us a line at info@mrmastic.co.uk with a few details of the job. We will give you a clear price, with a fixed price before we start.
Can sealant along the skirting be painted?
For painted skirting, we use a flexible product that can be painted. Silicone isn’t made to be painted, so it’s kept for wet areas and unpainted joints.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Can you add a movement joint to a tiled floor?
Often, yes. Straight cracks in grout often show where a movement joint was needed. We rake out that line and seal it with flexible sealant.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Honest limits
A few problems are outside what sealant work can do:
- Movement too big for a sealant joint
- Concrete repairs beyond the joint
- Water getting under the tiles from elsewhere
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
Joints and surfaces we work on
- Wet room & bathroom floors
- Concrete floor joints
- Thresholds
- Commercial floors
- Tiled floors
- Skirting boards
What the job involves on each surface
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. They’re resealed with a flexible, water-resistant sealant.
Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. They’re resealed with a product chosen for what runs over them.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Use a well-wrung mop rather than flooding the floor
- Walk round the room once a year and look at the edges
- Check the sealant is paintable before decorating
- Keep caulk for dry, still joints only
Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead especially in the first few days.
Small gaps are quick to seal. Ignored, they fill with dirt and open further and are harder to clean out.
