How we handle floor joint sealing in Donkey Street
In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. We reseal them with a product chosen for the movement and the traffic. We are often asked to deal with grout cracking in a straight line across a floor and perimeter joints in tiled floors filled with grout, across wet room & bathroom floors, thresholds and tiled floors.
For a small place like Donkey Street, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Do you need floor joint sealing in Donkey Street?
Floors and walls move a little with the seasons. In winter, with the heating on, timber dries and gaps open.
Most people get in touch after spotting something like this:
- Cracked grout where a tiled floor needs a movement joint
- Gaps at thresholds between rooms
- Skirting that has pulled away from the floor
- Grout used at the floor edge instead of sealant
Rented homes near Westenhanger station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.
Before you book anyone
- Is VAT in the price?
- Which colour the sealant will be
- Which sealant they’ll use, and why
- How much experience the applicator has

What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for most rooms, longer for large commercial floors in most cases. In a small place like Donkey Street, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in

Donkey Street: your questions answered
Is Donkey Street in your area for floor joint sealing?
Yes. We work across London and the South East, and Donkey Street is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Will you come out to Donkey Street?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What happens if it’s left?
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In a small place like Donkey Street, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Surface by surface
Commercial floors
Commercial washrooms and kitchens have floor joints that get wet constantly. They’re resealed with a flexible, water-resistant sealant.
Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. We reseal them with a floor-joint product suited to the traffic.
Joints and finishes in Donkey Street homes
Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.
If you look after a church, hall or community building such as Church of All Saints, joints in its floors, skirtings and thresholds need resealing as they wear.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Ask before painting over a sealed joint
- Mark off resealed joints in warehouses
- Keep floor cleaning water to a minimum at the edges
- Do not slide heavy items over sealed joints
Silicone sealant is not made to take paint. If you plan to paint, we will use a paintable product.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner.
