Floor joint sealing in Northam, done properly
Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints. Common call-outs are for chipped and open joints in warehouse floors and floor edges that trap water and grime, on wet room & bathroom floors, tiled floors and concrete floor joints.
Homes around Northam range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

What the job involves on each surface
Thresholds
Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. That line is converted to a flexible joint where it suits the floor.
New homes and floors in Northam
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. That is why the skirting and threshold joints need a flexible seal.
Managing a site like Bitterne Manor Primary School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early. Rented homes near Bitterne station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.

Common problems we fix in Northam
Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack, and the sealant or grout breaks.
Signs it’s time to call us include:
- Open joints around bathroom floor edges
- Gaps opening between the floor and skirting
- Threshold joints that have opened or worn
- Grout used at the floor edge instead of sealant
Community buildings like Church of St Augustine are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

What affects the cost of floor joint sealing
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- Any mould that needs treating
- Whether the work is at height
- The amount of work
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- How many joints, rooms or windows are involved
- Where the property is
- Whether it’s a home or a business
- A few pictures by email, if you can
If you are in Northam and need floor joint sealing, ring 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Looking after it afterwards
To keep the joints looking good and working properly:
- Lift furniture rather than dragging it across joints
- Ask before painting over a sealed joint
- Get cracks along tile grout lines looked at early
- Mark off resealed joints in warehouses
Don’t paint over silicone. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and the edges sound.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Loose, hollow or cracked tiles, which need a tiler
- Water getting under the tiles from elsewhere
- Subfloor problems that need a flooring contractor
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Tiled floors
- Wet room & bathroom floors
- Concrete floor joints
- Skirting boards
- Commercial floors
- Thresholds
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a morning or an afternoon for most homes. For a job in Northam, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we check the joint and the floor and agree which sealant suits it.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- 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.
How to prepare
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before

Questions from Northam
Can you help a landlord with a rental near Bitterne station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can you do floor joint sealing in Northam?
Yes. We work across London and the South East, and Northam is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Can grout be replaced with sealant on a tiled floor?
Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit so the floor can move.
Why does the gap under my skirting keep coming back?
Floors shrink and settle, especially in the first year or two and through the heating season opens the gap. Caulk tends to crack; a flexible sealant doesn’t.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Why not just use caulk?
Because caulk cracks where there’s movement or water. Floor edges move through the year, so a flexible sealant suits them better.
Are you fully insured?
Yes. We are fully insured.
