How we handle floor joint sealing in Walworth
We seal floor joints in homes, offices and commercial buildings across Walworth. Each job starts with looking at the floor and the gap, because the right sealant depends on both. We work on tiled floors, skirting boards and commercial floors, and common reasons people get in touch are skirting caulk that keeps splitting and failed seals where bathroom floors meet baths and panels.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.
Every job is covered by our 12-month guarantee.

Why deal with it now?
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job in most rooms. In a flat in Walworth, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

What else we do in Walworth
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 work takes a few hours for most rooms, longer for large commercial floors for a typical job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- 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 cleaned, vacuumed and backed where depth needs controlling.
- The sealant goes in, chosen for the floor and coloured to suit it.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Questions from Walworth
Is parking a problem for a job in Walworth?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you work for landlords with property near Elephant & Castle station?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What causes gaps between the floor and skirting?
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 does not.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or drop us an email.
Do you seal kitchen plinths to the floor?
Yes. Wet-area floor joints are sealed with a flexible, water-resistant silicone.
What affects the cost of floor joint sealing
Every job gets its own quote. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- Access and height
- Any working-time requirements on site
- How many rooms, windows or areas are involved
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Helping us quote
To help us quote quickly, let us know:
- Access, such as stairs, a lift or height

- The address or postcode of the job
- Photos by email, if that’s easy

Landlords, agents and businesses in Walworth
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Get cracks along tile grout lines looked at early
- Avoid sloshing water against skirting
- Cone off fresh joints until they’re ready
- Do not slide heavy items over sealed joints
Don’t paint over silicone. If you plan to paint, we will use a paintable product.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier.
How the job changes by surface
Thresholds
A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.
Tiled floors
Large or heated tiled floors need room to move. Where needed, a line of grout is replaced with flexible sealant in a matching colour.
Floor joint sealing around Walworth
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Floors around Greater London 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.
As a London address, Walworth can be tricky for parking: let us know about parking bays, permits or a driveway. If you let a flat or house near Elephant & Castle station, gaps at skirtings and thresholds are worth sealing between tenancies. For site and facilities teams at buildings such as Robert Browning Primary School, entrance and corridor floor joints take a lot of traffic.
