The process
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a morning or an afternoon for most homes in most cases. Parking around Rownhams is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First we check the joint and the floor and agree which sealant suits it.
- Old caulk, grout or sealant is removed from the joint.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- The sealant goes in, chosen for the floor and coloured to suit it.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about any water getting in
- Mention if the joints have been sealed before

About our floor joint sealing in Rownhams
Good floor joints come down to the right product and clean, prepared edges. We remove what’s there first, then clean, back and seal the joint. Typical jobs include rigid edge joints in tiled floors and threshold joints that have opened or worn, on thresholds, concrete floor joints and skirting boards.
In smaller places like Rownhams, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Questions from Rownhams
Can you help a landlord with a rental near Redbridge station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can you do floor joint sealing in Rownhams?
Yes. Our work covers London and the South East, and Rownhams is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Can grout be replaced with sealant on a tiled floor?
Normally, yes. A crack along a grout line often means the floor needs room to move. We replace that grout with a flexible joint.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Common problems we fix in Rownhams
Caulk is the usual filler for skirting. It cracks where there’s movement or water.
Common reasons people contact us include:
- Chipped and open joints in warehouse floors
- Skirting that has pulled away from the floor
- Failed seals where bathroom floors meet baths and panels
- Caulk that has cracked where the floor moves
Letting a property close to Redbridge station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.

What else we do in Rownhams
For landlords and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
Floor joints left open collect dirt that is hard to clean out and makes the floor look worn. Sealed joints are easier to keep clean. Homes in smaller places like Rownhams can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Colour picked to suit the job
- A choice of colours where the product allows
- A 12-month guarantee on all work

How the job changes by surface
Tiled floors
Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.
Thresholds
Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.
What floor joint sealing looks like in Rownhams
Across Southampton, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal.
If you look after a church, hall or community building such as Church of St John, floor and skirting joints in halls and kitchens wear like any others. If you look after a building such as Rownhams St John's Church of England Primary School, entrance and corridor floor joints take a lot of traffic.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
