How we handle floor joint sealing in Swaythling
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 using a product that suits the floor. If you’re dealing with skirting that has pulled away from the floor and cracked grout where a tiled floor needs a movement joint, we can help.
For a new home in or near Swaythling, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the cost of floor joint sealing
For a quick quote, just ask. The main things that affect it are:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- The address or postcode of the job
- Roughly how big the job is
- Photos by email, if that’s easy
There’s no standard price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or email us.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Large cracks that need a surveyor
- Floors that are uneven or need levelling
- Concrete repairs beyond the joint
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Why deal with it now?
Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. Around Swaythling, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Why us?
- We never seal over old sealant
- Sanitary silicone with an anti-fungal additive in wet areas
- White, clear, grey or coloured to suit, where the product allows
- 180+ five-star Google reviews

How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work normally takes a few hours for most rooms, longer for large commercial floors. In a smaller place like Swaythling, 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 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.
- 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.
Preparing for the visit
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Why does the gap under my skirting keep coming back?
Floors and walls move a little with the seasons, and new floors settle. A flexible sealant closes the gap without cracking like caulk.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Is caulk good enough for skirting?
Caulk is fine for dry joints that don’t move, but it cracks where there’s movement or water. For most floor joints, we use a flexible sealant.
Are you insured?
Yes. We are fully insured.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before any work starts.

New homes and floors in Swaythling
Across Southampton, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
Rented homes near Swaythling station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. If you look after a building such as Mansbridge Primary School, entrance and corridor floor joints take a lot of traffic.

Do you need floor joint sealing in Swaythling?
Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting.
Any of these means the joints need attention:
- Perimeter joints in tiled floors filled with grout
- Gaps opening between the floor and skirting
- Open joints that fill with dirt
- Cracked caulk along skirting in bathrooms and kitchens
Community buildings like St. Mary's Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Surface by surface
Wet room and bathroom floors
Bathroom floors meet baths, trays, panels and skirting. They’re sealed with a flexible, anti-fungal silicone that keeps water out.
Thresholds
Where a tiled floor meets timber or carpet, the joint takes movement from both sides. A flexible sealant bridges them.
