Floor joint sealing for homes and businesses in Selmeston
Floor joint sealing is mostly about choosing the right product and preparing the joint. We remove what’s there first, the joint is cleaned and backed where needed, then the new sealant goes in. Typical jobs include skirting that has pulled away from the floor and failed seals where bathroom floors meet baths and panels, across commercial floors, thresholds and tiled floors.
Somewhere as small as Selmeston, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
All our work is covered by a 12-month guarantee.

For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
What affects the quote in Selmeston
The price is agreed before any work begins. It’s based on:
- Whether the work is at height
- The number of rooms or windows
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What we need to know
Photos help, but a description is a good start. Please mention:
- If it’s domestic, commercial or a hotel
- The rough size of the job
- The address or postcode of the job
- Photos by email, if that is easy
Every job is quoted individually. Simply call 0345 464 0079 or send us an email and describe the job.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Loose, hollow or cracked tiles, which need a tiler
- Water getting under the tiles from elsewhere
- Bouncy or failing floorboards
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.

What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you reseal concrete floor joints in an industrial unit?
Yes. We clean out the joints and reseal them with a product suited to the floor. Let us know about the traffic when you ask for a quote.
How long before the joint can take traffic?
We’ll tell you before we leave. It depends on the sealant, and walking on it normally comes before mopping or wheeled traffic.
How it works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for most rooms, longer for large commercial floors from start to finish. Somewhere as small as Selmeston, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor.
- Finally, we check the work and talk you through aftercare.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

When to call us in Selmeston
Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away and the joint gets wider.
The most common problems we see are:
- Grout used at the floor edge instead of sealant
- Cracked caulk along skirting in bathrooms and kitchens
- Concrete floor joints that have broken down
- Cracked grout where a tiled floor needs a movement joint
If you let a flat or house near Berwick (Sussex) station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

Floor joint sealing in Selmeston: local notes
Across East Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.
Community buildings like The Parish Church of St Mary are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Why act early in Selmeston
Dirt builds up in open joints. A neat sealed joint is easier to clean and finishes the floor. In a small place like Selmeston, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.

Surface by surface
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. We rake out that line and seal it where it suits the floor.
Concrete floor joints
Hard wheels break down the edges of open joints. Sealing them supports the edges and stops debris collecting.
