Floor joint sealing for homes and businesses in Copnor
Wet-area floor joints keep water out of the gap behind skirting and plinths. We seal them with a flexible, water-resistant sealant. If you have gaps between floors and kitchen plinths and rigid edge joints in tiled floors, we can help, whatever the surface.
Where new homes go up in smaller places like Copnor, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What floor joint sealing looks like in Copnor
Floors around Portsmouth run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
Community buildings like Church of St Alban are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. If you let a flat or house near Fratton station, gaps at skirtings and thresholds are worth sealing between tenancies.

Common questions in Copnor
Do you cover Copnor for floor joint sealing?
Yes. Our work covers London and the South East, and Copnor is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is Copnor within the area you cover?
Yes. Copnor is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
How soon can the floor be mopped?
You’ll get the times before we go. That depends on the product, and walking on it generally comes before mopping or wheeled traffic.
Can sealant along the skirting be painted?
On joints you want to paint, yes. Silicone does not take paint.
Why has a gap opened under my skirting?
Floors and walls move a little with the seasons, and new floors settle. We close it with a flexible sealant that moves with the floor.
Is caulk good enough for skirting?
Caulk can’t cope with movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
What happens on the day
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most rooms, longer for large commercial floors for a typical job. For a job in Copnor, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- We take out any old caulk, sealant or grout along the line.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Preparing for the visit
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

Advice
Landlord and commercial work in Copnor
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
Why act early in Copnor
Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. In a smaller place like Copnor, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Do you need floor joint sealing in Copnor?
Floors and walls move a little with the seasons. In winter, with the heating on, timber dries and gaps open, then close again in damper months.
Signs it’s time to call us include:
- Grout used at the floor edge instead of sealant
- Failed seals where bathroom floors meet baths and panels
- Caulk that has cracked where the floor moves
- Open joints that fill with dirt
For site and facilities teams at buildings such as Westover Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
