Your questions about floor joint sealing in Long Sutton
Do you cover Long Sutton for floor joint sealing?
Yes. Our work covers London and the South East, and Long Sutton is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Is Long Sutton within the area you cover?
Yes, Long Sutton is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What causes gaps between the floor and skirting?
It’s normally the floor moving: heating drying the timber, or a filler that’s too rigid. A flexible bead keeps up with the movement.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
How long does floor joint sealing take?
As a guide, most jobs take a few hours for most rooms, longer for large commercial floors. Bigger jobs take longer.
Floor joint sealing for homes and businesses in Long Sutton
The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk generally cracks where there’s movement, so we close it with a flexible sealant instead. If you’re dealing with grout cracking in a straight line across a floor and rigid edge joints in tiled floors, we can help, whatever the surface.
In a village or hamlet like Long Sutton, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Whatever the size of the job, it’s backed by our one-year guarantee in Long Sutton and across Hampshire.

What affects the cost of floor joint sealing
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating
- The number of rooms or windows
- Access and height
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

How the job changes by surface
Thresholds
Thresholds take daily traffic, so the sealant has to be tough as well as flexible and tool it flush.
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. They’re resealed with a flexible, water-resistant sealant.
Should I try it myself first?
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on the length of joint. For a village or hamlet like Long Sutton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

Advice
Why act early in Long Sutton
Regrouting a cracked line in a tiled floor rarely fixes it. The movement is still there, so the grout fails again. A flexible movement joint is the fix. Where a wall is exposed, as many are in small places like Long Sutton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Floor joint sealing in Long Sutton: local notes
Floors around Hampshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
Community buildings like Church of All Saints are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. Letting a property close to Bentley (Hampshire) station? Then gaps at skirtings and thresholds are worth sealing between tenancies.

Common problems we fix in Long Sutton
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting.
The most common problems we see are:
- Perimeter joints in tiled floors filled with grout
- Gaps opening between the floor and skirting
- Tiled floors with no room to move
- Gaps between floors and kitchen plinths
For site and facilities teams at buildings such as Long Sutton Church of England Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
Questions to ask before you book
- What happens if the job turns out different
- How long to leave it before use
- Whether they seal over old material or remove it
- Whether you can choose the colour
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Use furniture pads near skirting
- Keep caulk for dry, still joints only
- Avoid sloshing water against skirting
- Cone off fresh joints until they’re ready
Keep heavy furniture from dragging across the joints. Dragging can tear the bead especially in the first few days.
Small gaps are quick to seal. Left alone, they collect dirt and widen.
