Floor Joint Sealing in Felbridge

Surface by surface
Thresholds
Thresholds take daily traffic, so we choose a hard-wearing, flexible product.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. A sealed joint protects the edges.
Floor joint sealing in Felbridge, done properly
Concrete floors in warehouses and units have joints that take heavy wear. Each is resealed with a floor-joint product suited to what runs over it. If you’re dealing with tiled floors with no room to move and open gaps along the bottom of skirting boards, we can put it right, whatever the surface.
Older homes in small places like Felbridge often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work comes with a 12-month guarantee, wherever you are in West Sussex.

When to call us in Felbridge
An open floor joint fills with dirt and water. In kitchens and bathrooms, mop water gets into the gap and behind skirting and plinths.
It’s worth asking for a quote if you see:
- Cracked grout where a tiled floor needs a movement joint
- Gaps opening between the floor and skirting
- Rigid edge joints in tiled floors
- Threshold joints that have opened or worn
For site and facilities teams at buildings such as Felbridge Primary School, entrance and corridor floor joints take a lot of traffic.
What your quote should include
- The length of the guarantee
- Whether VAT is included
- How hidden problems are handled
- Whether you can choose the colour
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
FAQs for Felbridge
Will you come out to Felbridge?
Yes, we do. We work across 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 Felbridge in your area for floor joint sealing?
Yes, Felbridge is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.
Why has a gap opened under my skirting?
Floors and walls move a little with the seasons, and new floors settle. We close it with a flexible sealant that moves with the floor.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Can you reseal concrete floor joints in an industrial unit?
Yes. We reseal concrete floor joints in commercial and industrial units. The product is chosen for the traffic the floor takes.
Do you seal floor joints in bathrooms and kitchens?
Yes. These joints get wet every time the floor is cleaned, so a flexible silicone is the right choice.
Can grout be replaced with sealant on a tiled floor?
Generally, yes. A crack along a grout line often means the floor needs room to move. We replace that grout with a flexible joint.

How the visit works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take a morning or an afternoon for most homes. Somewhere like Felbridge needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we check the joint and the floor and agree which sealant suits it.
- Old caulk, grout or sealant is removed from the joint.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

What happens if it’s left?
Putting new grout into a crack that keeps reappearing does not last. The movement is still there, so the grout fails again. A flexible movement joint is the fix. Older cottages and farmhouses around Felbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
