Why act early in Dunton Green
Water that gets past a floor joint can damage the floor beneath. Sealing them now keeps the problem at the surface. Around Dunton Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Different surfaces, different methods
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. Sealing them supports the edges and keeps dirt out.
Skirting boards
Skirting gaps are one of the most common floor joints we seal. The old caulk is removed first.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Common questions in Dunton Green
Is Dunton Green in your area for floor joint sealing?
Yes, Dunton Green is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Dunton Green station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will I be able to paint over the new joint?
Where you plan to paint, we do. Silicone in bathrooms and kitchens can’t be painted so mention it when you get a quote.
Why not just use caulk?
Caulk cannot cope with movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How long does floor joint sealing take?
Most jobs take a few hours, depending on the length of joint, including preparation and clearing up. We will confirm how long when we quote.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, wherever you are.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
