What we’re called out for in Crosspost
Wheels crossing an unfilled concrete joint chip its edges. Hard wheels damage the joint edges.
If you can see any of these, it’s time to have the joints looked at:
- Open joints around bathroom floor edges
- Cracked grout where a tiled floor needs a movement joint
- Floor edges that trap water and grime
- Grout used at the floor edge instead of sealant
If you look after a church, hall or community building such as St Mary Magdalene's Church, joints in its floors, skirtings and thresholds need resealing as they wear.

How we handle floor joint sealing in Crosspost
We seal floor joints in homes, offices and commercial buildings across Crosspost. We start by checking the floor type and the joint, since that decides which sealant suits. We work on tiled floors, commercial floors and thresholds, and people most often call us about threshold joints that have opened or worn and open gaps along the bottom of skirting boards.
Older homes in small places like Crosspost often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Surface by surface
Tiled floors
When grout cracks along a straight line, the floor is telling you it needs to move. That line is converted to a flexible joint if it’s in the right place.
Concrete floor joints
Sawn joints in concrete floors control where it cracks. They’re resealed with a product chosen for what runs over them.
What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a morning or an afternoon for most homes. Somewhere like Crosspost needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can

What floor joint sealing looks like in Crosspost
Floors around West Sussex 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.
Managing a site like Bolney CofE Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Rented homes near Wivelsfield station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Use furniture pads near skirting
- Avoid caulk in bathrooms and kitchens
- Get cracks along tile grout lines looked at early
- Do not paint over silicone
Avoid flooding the floor when you clean. Less water at the edges helps the joints last.
A gap under the skirting collects dust and lets draughts through. Sealing it early keeps the room cleaner.
Common questions in Crosspost
Is Crosspost within the area you cover?
Yes, Crosspost is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do floor joint sealing in Crosspost?
Yes. Our work covers London and the South East, and Crosspost is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
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.
How do I get a quote for floor joint sealing in Crosspost?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or email us with a short description of the job.
Do you seal floor joints in bathrooms and kitchens?
Yes. Floor edges in bathrooms and kitchens get wet at every clean, so a flexible silicone is the right choice.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can sealant along the skirting be painted?
If you tell us beforehand, yes. We use a paintable flexible sealant on joints you plan to paint and wet areas get silicone.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What affects the cost of floor joint sealing
We don’t publish a price list, because jobs vary so much. What we look at:
- Any mould that needs treating
- The product the joint needs
- The size of the job
- The number of rooms or windows
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Whether it has been sealed before
- Pictures of the joints, sent by email
- Roughly how big the job is
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Why act early in Crosspost
Putting new grout into a crack that keeps reappearing does not last. The movement is still there, so the grout fails again. Replacing that line with flexible sealant gives it somewhere to go. Where a wall is exposed, as many are in small places like Crosspost, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Anti-fungal silicone where joints get wet
- Neat joints and a tidy finish
- White, clear, grey or another colour, product permitting
- An ARBOMaster approved applicator
