Surface by surface
Concrete floor joints
Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. They’re resealed with a flexible, water-resistant sealant.
Common problems we fix in Sydenham
Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting and they change again in summer.
Keep an eye out for these signs:
- Floor edges that trap water and grime
- Open gaps along the bottom of skirting boards
- Tiled floors with no room to move
- Gaps at thresholds between rooms
For landlords with property near Haddenham & Thame Parkway station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

Your questions about floor joint sealing in Sydenham
Is Sydenham within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Sydenham for floor joint sealing?
Yes, Sydenham is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
What causes gaps between the floor and skirting?
Timber floors and skirting shrink and swell through the year. A flexible sealant closes the gap without cracking like caulk.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Why not just use caulk?
Because caulk cracks where there’s movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.
Can I add another job to the visit?
Yes. Just list everything you need.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
For anyone letting property in or around Sydenham, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
What affects the cost of floor joint sealing
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- Whether the work is at height
- How much there is to do
- The number of rooms or windows
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
Every job is quoted individually, so start by telling us what you need. Simply phone 0345 464 0079 or email us and describe the job.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours, depending on the length of joint. Somewhere like Sydenham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided 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.
How to prepare
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Clear the area around the work

Floors around Oxfordshire 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.
For buildings such as Church of St Mary, floor and skirting joints in halls and kitchens wear like any others.
