Floor & skirting joints in Kennington, Oxfordshire
We cover Kennington for sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Skirting caulk that keeps splitting
- Concrete floor joints that have broken down
- Perimeter joints in tiled floors filled with grout
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Floor joint sealing in Kennington, done properly
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out and stops dirt collecting. We work on tiled floors, skirting boards and commercial floors, and the jobs we see most are open joints around bathroom floor edges and concrete floor joints that have broken down.
In and around Kennington, floors range from older timber boards to tiles and newer finishes, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

What else we do in Kennington
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most rooms, longer for large commercial floors. Parking around Kennington is normally easier than in a town centre, but mention any lanes, gates or long drives. 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.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- 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.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Getting ready for the visit
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work

Advice
Why act early in Kennington
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. Homes in smaller places like Kennington can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

What floor joint sealing looks like in Kennington
Floors around Oxfordshire run from suspended timber in older homes to concrete in newer houses and 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 Radley station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a church, hall or community building such as St Swithun's Church, floor and skirting joints in halls and kitchens wear like any others. For site and facilities teams at buildings such as St Swithun's CofE Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Kennington: your questions answered
Is Kennington in your area for floor joint sealing?
Yes. We work across London and the South East, and Kennington is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.

Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Are you insured?
Yes. Mr Mastic is fully insured.
Can sealant along the skirting be painted?
Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone is not made to be painted, so we use it where the joint stays unpainted.
How long does floor joint sealing take?
A typical job takes a few hours, depending on the length of joint, including preparation and clearing up. We will confirm how long when we quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Vacuum floor joints regularly to stop grit building up
- Avoid caulk in bathrooms and kitchens
- Get cracks along tile grout lines looked at early
- Check the sealant is paintable before decorating
Keep heavy furniture from dragging across the joints. Dragging can tear the bead especially in the first few days.
Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen and are harder to clean out.
How we quote for floor joint sealing
Some jobs are bigger than they look, and some smaller. The main factors:
- The amount of work
- Whether there’s mould to deal with
- Working hours on commercial sites
- Which sealant suits the joint
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
- Where the job is, and your postcode
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved and send you a clear quote.
What the job involves on each surface
Skirting boards
Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing.
Concrete floor joints
We clean concrete joints out thoroughly before sealing first. Backing goes in where the depth needs controlling.
