What floor joint sealing looks like in Blackheath
Across Surrey, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
Community buildings like Church of St Martin are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. Schools such as Chilworth CofE (Aided) Infant School are buildings too, and entrance and corridor floor joints take a lot of traffic.

About our floor joint sealing in Blackheath
Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. We seal skirting gaps, tiled floor movement joints and concrete floor joints using a product that suits the floor. If you’re dealing with tiled floors with no room to move and grout used at the floor edge instead of sealant, we can help, on wet room & bathroom floors, concrete floor joints and skirting boards alike.
In a village or hamlet like Blackheath, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Avoid sloshing water against skirting
- Don’t slide heavy items over sealed joints
- Cone off fresh joints until they’re ready
- Have a cracking tiled floor checked before tiles break
Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
What we’re called out for in Blackheath
Caulk is the usual filler for skirting. In a joint that moves or gets wet, it splits, which is why so many skirting joints look broken.
The most common problems we see are:
- Floor edges that trap water and grime
- Perimeter joints in tiled floors filled with grout
- Skirting that has pulled away from the floor
- Gaps between floors and kitchen plinths
If you let a flat or house near Chilworth station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.
What your quote should include
- How hidden problems are handled
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- How much experience the applicator has
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes a few hours, depending on the length of joint. For a village or hamlet like Blackheath, 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.
- Any old caulk, grout or sealant is raked or cut out.
- The joint is vacuumed clean and backing fitted where needed.
- The chosen sealant goes in, coloured to suit the floor.
- The joint is tooled neatly and the cure time explained.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Advice
Also in Blackheath
Why deal with it now?
Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant moves with the floor. Older cottages and farmhouses around Blackheath can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Surface by surface
Thresholds
A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.
Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. They’re resealed with a product chosen for what runs over them.
What affects the cost of floor joint sealing
For a quick quote, just ask. What matters most is:
- Access and height
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- The product the joint needs
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
When you call or email, these details help:
- If someone has resealed it before
- The type of property
- The rough size of the job
- What’s wrong with the joints now

Blackheath questions
I let a flat near Chilworth station. Can you help?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Blackheath?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is the work guaranteed?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Can you use decorators’ caulk instead?
Caulk can’t cope with movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.
What sealant work cannot fix
It helps to know what we can’t do:
- Leaks from a failed tanking system
- Large cracks that need a surveyor
- Cracked or broken concrete slabs
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.
