Clothall Floor Joint Sealing
Our applicators work in Clothall on sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Failed joint filler in concrete floors
- Floor edges that trap water and grime
- Grout used at the floor edge instead of sealant
Floor joint sealing in Clothall
A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors so the joint stays neat. Common call-outs are for threshold joints that have opened or worn and gaps opening between the floor and skirting, on commercial floors, tiled floors and skirting boards.
Older homes in small places like Clothall often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Common problems we fix in Clothall
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges.
The most common problems we see are:
- Worn sealant at door thresholds
- Cracked grout where a tiled floor needs a movement joint
- Cracked caulk along skirting in bathrooms and kitchens
- Gaps between floors and kitchen plinths
For buildings such as Church of St Mary, floor and skirting joints in halls and kitchens wear like any others.
What your quote should include
- The length of the guarantee
- Is VAT in the price?
- Whether they seal over old material or remove it
- How much experience the applicator has
New homes and floors in Clothall
Floors around Hertfordshire 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.
If you let a flat or house near Baldock station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. Managing a site like Weston Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
Clothall is about 3 miles east of Letchworth, in Hertfordshire. Jobs in Clothall get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Our Hertfordshire coverage runs to 381 places, Clothall among them. We also work in Chelmsford, about 32 miles from Clothall.

What the job involves on each surface
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. We rake out any grout there and reseal.
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. Where water is involved, silicone is the better choice.
Why act early in Clothall
Left open, concrete joints break down under traffic. A sealed joint supports the edges and keeps the damage down. Older cottages and farmhouses around Clothall can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What you get with us
- Sealant colour chosen to suit

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Get cracks along tile grout lines looked at early
- Walk round the room once a year and look at the edges
- Ask before painting over a sealed joint
- Keep floor cleaning water to a minimum at the edges
Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead before it has fully cured.
Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.
Clothall questions
Is Clothall in your area for floor joint sealing?
Yes, Clothall is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Will you come out to Clothall?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Is caulk good enough for skirting?
Caulk is fine for dry joints that don’t move, but it cracks where there’s movement or water. For most floor joints, we use a flexible sealant.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Should I try it myself first?
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.
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.
