Floor Joint Sealing in Gundleton
Sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints for homeowners, landlords and businesses in Gundleton. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Perimeter joints in tiled floors filled with grout
- Floor edges that trap water and grime
- Threshold joints that have opened or worn
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check the sealant is paintable before decorating
- Walk round the room once a year and look at the edges
- Keep floor cleaning water to a minimum at the edges
- Use furniture pads near skirting
Check the joints after the first winter. If anything has opened, it’s easy to reseal before they spread.
Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.
How we handle floor joint sealing in Gundleton
In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. Each is resealed with a floor-joint product suited to what runs over it. If you are dealing with cracked caulk along skirting in bathrooms and kitchens and tiled floors with no room to move, we can help.
Somewhere as small as Gundleton, new homes tend to be conversions, self-builds or a few houses rather than an 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 Gundleton and across Hampshire.

Leave it or put it right?
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. Older cottages and farmhouses around Gundleton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.

How the job changes by surface
Skirting boards
If the skirting is painted, a paintable flexible sealant works well. Where water is involved, silicone is the better choice.
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. They’re resealed with a flexible, water-resistant sealant.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most rooms, longer for large commercial floors. Somewhere as small as Gundleton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
How to prepare
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

Advice
Do you need floor joint sealing in Gundleton?
Caulk is the usual filler for skirting. It cracks where there’s movement or water.
Common reasons people contact us are:
- Dirt and water collecting in open floor joints
- Cracked grout where a tiled floor needs a movement joint
- Perimeter joints in tiled floors filled with grout
- Failed joint filler in concrete floors
If you look after a church, hall or community building such as Church of All Saints, joints in its floors, skirtings and thresholds need resealing as they wear.
What to look for in a quote
- Who does the work, and how experienced they are
- Which sealant they’ll use, and why
- How long to leave it before use
- What insurance they hold
When something else is needed
We’ll always be straight with you, so here’s what sealant can’t fix:
- Large cracks that need a surveyor
- Failed waterproofing under a wet room floor
- Concrete repairs beyond the joint
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before booking.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Floor joint sealing in Gundleton: local notes
Floors around Hampshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
Schools such as Perins School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early.
