Floor Joint Sealing in St Mary Hoo
Floor joints in St Mary Hoo need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Open joints that fill with dirt
- Gaps at thresholds between rooms
- Grout cracking in a straight line across a floor
Surface by surface
Skirting boards
If the skirting is painted, a paintable flexible sealant works well. In wet rooms and kitchens, silicone is normally better.
Thresholds
A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.
Floor joint sealing for homes and businesses in St Mary Hoo
Good floor joints come down to the right product and clean, prepared edges. We remove what’s there first, the joint is cleaned and backed where needed, then the new sealant goes in. We work on commercial floors, concrete floor joints and tiled floors, and common reasons people get in touch are grout cracking in a straight line across a floor and skirting caulk that keeps splitting.
In a village or hamlet like St Mary Hoo, 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 there’s a problem with our work within the year, let us know and we will sort it.

For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Housing providers, facilities teams and property managers book us too in St Mary Hoo and across Medway. We can quote a run of properties together, and we are fully insured for the work.
Why deal with it now?
Floor joints left open collect dirt that is hard to clean out. A neat sealed joint is easier to clean and finishes the floor. Around St Mary Hoo, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Keep dirt out of the joints
- Keep heavy wheels off new concrete joints until cured
- Use furniture pads near skirting
- Keep caulk for dry, still joints only
Have a look at the joints once the heating season is over. If anything has opened, it’s easy to reseal before they spread.
A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.
What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a morning or an afternoon for most homes, depending on the size of the job. Somewhere like St Mary Hoo needs a little journey planning: 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 clear the edges of the floor so the joints are easy to reach.
- We take out the cracked caulk, grout or old sealant.
- We clean and dry the edges of the joint.
- We apply a flexible sealant suited to the floor and smooth it.
- We check the joints and explain the aftercare.
How to prepare
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
Getting a quote
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or drop us an email and describe the job.
Advice
Should I try it myself first?
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.
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.
Honest limits
It helps to know what we cannot do too:
- A tiled floor that needs relaying
- Failed waterproofing under a wet room floor
- Concrete repairs beyond the joint
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Floor joint sealing around St Mary Hoo
Across Medway, 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.
Around St Mary Hoo, as everywhere, floor joint sealing is only as good as the preparation behind it. If you look after a church, hall or community building such as Church of St Mary, joints in its floors, skirtings and thresholds need resealing as they wear.

FAQs for St Mary Hoo
Is there a guarantee on floor joint sealing in St Mary Hoo?
All our work, in St Mary Hoo and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like St Mary Hoo?
Yes, St Mary Hoo is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Are you fully insured?
Yes. We are fully insured for every job we do.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Do you use a paintable sealant?
For painted skirting, we use a flexible product that can be painted. Silicone won’t take paint, so it’s kept for wet areas and unpainted joints.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
How long will you be here?
Typically it takes a few hours for most rooms, longer for large commercial floors. Larger jobs naturally take longer, and we’ll say how long yours will take.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
