Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating

How we handle floor joint sealing in Hunsdon
Across Hunsdon, we seal floor and skirting joints in homes and businesses. Each job starts with looking at the floor and the gap, since that decides which sealant suits. Typical jobs include skirting that has pulled away from the floor and open joints that fill with dirt, across tiled floors, wet room & bathroom floors and commercial floors.
For a small place like Hunsdon, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Hunsdon questions
Can you help a landlord with a rental near Roydon station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Hunsdon?
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.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Are you insured?
Yes. Full insurance covers our work.
How soon can the floor be mopped?
That varies with the sealant and the room. Before we leave, we tell you when it can be walked on, mopped and driven over so there’s no guesswork.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
Will I be able to paint over the new joint?
Where you plan to paint, we do. Silicone doesn’t take paint.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for most rooms, longer for large commercial floors.

- Old material is removed from the joint.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor and tooled.
- Finally, we check the work and talk you through aftercare.
Getting ready for the visit

Keeping the joints in good condition
Looking after new joints is easy:
- Lift furniture rather than dragging it across joints
- Use a well-wrung mop rather than flooding the floor
- Avoid caulk in bathrooms and kitchens
- Cone off fresh joints until they’re ready
Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.
A gap under the skirting collects dust and lets draughts through. Sealing it early keeps the room cleaner and the edges sound.

Leave it or put it right?
Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant moves with the floor, so the joint stays closed. Where a wall is exposed, as many are in small places like Hunsdon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
New homes and floors in Hunsdon
Across Hertfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.
Letting a property close to Roydon station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant. Schools such as Hunsdon Junior Mixed and Infant School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early. For buildings such as St Francis Chapel, floor and skirting joints in halls and kitchens wear like any others.
