Why it’s worth doing now in Portsea
Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. In an older home around Portsea, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

About our floor joint sealing in Portsea
Every floor moves a little, so its edges need a joint that can flex. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed. We work on skirting boards, thresholds and commercial floors, and people most often call us about gaps between floors and kitchen plinths and floor edges that trap water and grime.
In smaller places like Portsea, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What we do, step by step
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours, depending on the length of joint for a typical job. In a smaller place like Portsea, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor and smooth it.
- We check the joints and explain the aftercare.
How to prepare
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

Advice
Keeping the joints in good condition
So the new joints stay in good condition:
- Act on grout cracks that run in a straight line
- Keep dirt out of the joints
- Keep caulk for dry, still joints only
- Use a well-wrung mop rather than flooding the floor
Follow the cure time before walking on or cleaning the joint. Light foot traffic is generally fine sooner than wet cleaning or wheels so we will give you each time.
A gap under the skirting collects dust and lets draughts through. Sealing it early keeps the room cleaner.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What affects the quote in Portsea
The quote reflects the job in front of us. We look at:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- The size of the job
- How many rooms, windows or areas are involved
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- The rough size of the job
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- The address or postcode of the job
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
Signs you need floor joint sealing in Portsea
Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack and joints fail.
These are the problems we’re asked about most:
- Chipped and open joints in warehouse floors
- Open gaps along the bottom of skirting boards
- Open joints that fill with dirt
- Cracked caulk along skirting in bathrooms and kitchens
For buildings such as St Ann's Church, floor and skirting joints in halls and kitchens wear like any others.
What to look for in a quote

Yes. We work across London and the South East, and Portsea is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Why does the gap under my skirting keep coming back?
Timber floors and skirting shrink and swell through the year. We close it with a flexible sealant that moves with the floor.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours for most rooms, longer for large commercial floors. We’ll give you a better idea when we quote.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you use decorators’ caulk instead?
Only on dry joints that do not move. It splits once the floor shifts and the gap reopens. A flexible sealant is the better choice.
