Floor joint sealing in Blackboys, 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 using a product that suits the floor. We work on thresholds, wet room & bathroom floors and skirting boards, and common reasons people get in touch are open joints around bathroom floor edges and perimeter joints in tiled floors filled with grout.
For a small place like Blackboys, the journey and access are planned in advance, and the work itself is the same as on any site.
Each job carries a 12-month guarantee, large or small.

New homes and floors in Blackboys

Different surfaces, different methods
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.
Skirting boards
Skirting-to-floor joints are a regular job for us. The old caulk is removed first so the new sealant bonds.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Use furniture pads near skirting
- Vacuum floor joints regularly to stop grit building up
- Check skirting joints after the heating season
- Check the sealant is paintable before decorating
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed while it cures.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and the edges sound.
Blackboys: your questions answered
Can you help a landlord with a rental near Buxted station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Blackboys?
Yes. Blackboys is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where are you based?
Mr Mastic is based in Crawley. We cover Blackboys and the rest of East Sussex.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Why not just use caulk?
Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
What we can’t put right
It helps to know what we can’t do too:
- Concrete repairs beyond the joint
- Bouncy or failing floorboards
- Tiles that have lifted or broken
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.

What affects the cost of floor joint sealing
We don’t publish a price list. What we look at:
- The old material and how stubborn it is
- Working hours on commercial sites
- Whether there’s mould to deal with
- Access and height
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
What we need to know
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- Roughly how big the job is
- A few pictures by email, if you can
We quote each job on its own, so start by telling us what you need. Simply call 0345 464 0079 or drop us an email and describe the job.
What happens if it’s left?
Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. Where a wall is exposed, as many are in small places like Blackboys, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.
What you get with us
- Trusted Arbo and Everbuild sealants
- Any old sealant cut out fully, not covered over
- Sanitary silicone with an anti-fungal additive in wet areas
- We are fully insured
Common problems we fix in Blackboys
When a tiled floor has no movement joints, the grout takes the strain. You will see a crack running along the grout, showing where a movement joint was needed.
Keep an eye out for these signs:
- Skirting caulk that keeps splitting
- Open joints around bathroom floor edges
- Grout cracking in a straight line across a floor
- Chipped and open joints in warehouse floors
If you look after a building such as Blackboys Church of England Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.
What to look for in a quote
- How long the guarantee is
- How much experience the applicator has
- How long to leave it before use
- How the colour is chosen
The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours, depending on the length of joint. For a village or hamlet like Blackboys, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Getting ready for the visit
- Clear the area around the work
- Mention any tricky access
- Let us know about earlier repairs to the joints
