FAQs for Southborough
Is parking a problem for a job in Southborough?
Parking in Southborough, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Is Southborough in your area for floor joint sealing?
Yes. Our work covers London and the South East, and Southborough is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Where is Mr Mastic based?
We work from Crawley. We cover Southborough and the rest of Greater London.
Do you use a paintable sealant?
Where you plan to paint, we do. Silicone in bathrooms and kitchens can’t be painted, so tell us your plans.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Floor joint sealing in Southborough
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 work on tiled floors, wet room & bathroom floors and concrete floor joints, and common reasons people get in touch are cracked grout where a tiled floor needs a movement joint and threshold joints that have opened or worn.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Different surfaces, different methods
Commercial floors
Commercial washrooms and kitchens have floor joints that get wet constantly. We reseal them with a sealant suited to wet areas.
Thresholds
Two different floors meeting at a threshold move differently. A flexible sealant bridges them.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Do not slide heavy items over sealed joints
- Check the sealant is paintable before decorating
- Walk round the room once a year and look at the edges
- Avoid caulk in bathrooms and kitchens
Keep off the joint for the time we give you. Light foot traffic is usually fine sooner than wet cleaning or wheels.
Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.
Joints and finishes in Southborough homes
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
Managing a site like Southborough Primary School? Then entrance and corridor floor joints take a lot of traffic. If you look after a church, hall or community building such as St Augustine's Church, joints in its floors, skirtings and thresholds need resealing as they wear. Southborough is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What affects the cost of floor joint sealing
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- Working hours on commercial sites
- Whether the work is at height
- The number of rooms or windows
What you pay reflects the work, not guesswork. That is why we ask about the job first.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we will come back to you with a quote.
Why act early in Southborough
Water that gets past a floor joint can damage the floor beneath. Sealing them now keeps the problem at the surface. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

What happens on the day
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. The work usually takes a morning or an afternoon for most homes. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we check the joint and the floor and agree which sealant suits it.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- 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.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
