About our floor joint sealing in Calshot
Floor joint sealing is mostly about choosing the right product and preparing the joint. We remove what’s there first, then clean, back and seal the joint. If you have cracked grout where a tiled floor needs a movement joint and concrete floor joints that have broken down, we can help, on wet room & bathroom floors, tiled floors and commercial floors alike.
Around Calshot, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not 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 questions in Calshot
Is Calshot within the area you cover?
Yes. Calshot is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Hamble station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Can you add a movement joint to a tiled floor?
Often, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Housing providers, facilities teams and property managers book us too in Calshot and across Hampshire. We can quote a run of properties together, and we are fully insured.

Leave it or put it right?
Leaving skirting gaps until the next decorating job lets dirt and draughts in. It’s a quick job to seal them now. In a small place like Calshot, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

How the job changes by surface
Concrete floor joints
Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.
Thresholds
Two different floors meeting at a threshold move differently. A flexible sealant bridges them.
Do you need floor joint sealing in Calshot?
A new floor or screed shrinks and settles as it dries. Gaps at the edges appear in the first year or so.
Any of these means the joints need attention:
- Gaps between floors and kitchen plinths
- Dirt and water collecting in open floor joints
- Cracked caulk along skirting in bathrooms and kitchens
- Tiled floors with no room to move
If you look after a church, hall or community building such as St George, joints in its floors, skirtings and thresholds need resealing as they wear.
What to look for in a quote
- How long to leave it before use
- How hidden problems are handled
- Whether they’re fully insured
- Whether all the old sealant comes out first
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for most rooms, longer for large commercial floors, including the tidy-up. Somewhere as small as Calshot, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- 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.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Mention any parking rules near the property

Advice
What sealant work cannot fix
