Floor joint sealing for homes and businesses in Southampton
Wet-area floor joints keep water out of the gap behind skirting and plinths. A flexible silicone seal keeps it out and stops dirt collecting. We work on commercial floors, wet room & bathroom floors and concrete floor joints, and people most often call us about worn sealant at door thresholds and tiled floors with no room to move.
Plenty of homes in Southampton are on estates built in the last few decades, where the original builder’s sealant around baths, frames and skirtings may be past its best. Snagging and second-fix sealing are part of what we do for developers and new-home owners alike.
Each job carries a 12-month guarantee.

Signs you need floor joint sealing in Southampton
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges until the joint widens.
The most common problems we see are:
- Floor edges that trap water and grime
- Grout used at the floor edge instead of sealant
- Cracked caulk along skirting in bathrooms and kitchens
- Failed seals where bathroom floors meet baths and panels
Rented homes near St Denys station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.
Questions to ask before you book
- How much experience the applicator has
- The length of the guarantee
- Is VAT in the price?
- Whether you can choose the colour
Why act early in Southampton
Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. For landlords in Southampton, failed sealant soon turns into tenant complaints about mould, damp or draughts. It’s simpler to sort between tenants than in the middle of a let.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Surface by surface
Skirting boards
Skirting-to-floor joints are a regular job for us. We take out any cracked caulk before sealing.
Concrete floor joints
We clean concrete joints out thoroughly before sealing, vacuuming them clean. We fit backing where needed.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Avoid sloshing water against skirting
- Sweep along the edges of the floor
- Look at floor joints each spring
- Avoid caulk in bathrooms and kitchens
Follow the cure time before walking on or cleaning the joint. Light foot traffic is normally fine sooner than wet cleaning or wheels so we will give you each time.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. Resealing early keeps it out.

Southampton: your questions answered
Is there a guarantee on floor joint sealing in Southampton?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
I let a flat near St Denys station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Do you have insurance?
Yes. We’re fully insured.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a morning or an afternoon for most homes. For homes and businesses in busier parts of Southampton, parking needs a little planning. Let us know about stairs, lifts or shared entrances too.
- First we check the joint and the floor and agree which sealant suits it.
- Old caulk, grout or sealant is removed from the joint.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
How to prepare
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or drop us an email.
Advice
Joints and finishes in Southampton homes
Across Southampton, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
For buildings such as Saint Mary's, floor and skirting joints in halls and kitchens wear like any others. Managing a site like Bevois Town Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
