Common problems we fix in Selsdon
A floor laid tight to the walls has no room to move. As it expands, the edges lift or crack and joints fail.
Any of these means the joints need attention:
- Rigid edge joints in tiled floors
- Gaps opening between the floor and skirting
- Open joints that fill with dirt
- Cracked grout where a tiled floor needs a movement joint
Community buildings like St Francis are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Floor joint sealing for homes and businesses in Selsdon
Every floor moves a little, so its edges need a joint that can flex. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed with a sealant suited to the movement and traffic. We work on skirting boards, wet room & bathroom floors and commercial floors, and people most often call us about gaps between floors and kitchen plinths and tiled floors with no room to move. Whether you’re looking for a local mastic man, a sealant applicator or a sealant contractor in Selsdon, Mr Mastic can help.
New flats are going up across London, many of them 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.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for most rooms, longer for large commercial floors. In a London area like Selsdon, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied and smooth it.
- Finally, we check the work and talk you through aftercare.
How to prepare
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Selsdon questions
Do you cover Selsdon for floor joint sealing?
Yes. We work across London and the South East, and Selsdon is part of that. You can ring 07833 053749 or email us and tell us what needs doing.
Can parking be tricky for a visit in Selsdon?
Parking in Selsdon, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is it messy?
We keep the work tidy. Nearby surfaces are protected.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can you seal where the floor meets the bath panel?
Yes. Wet-area floor joints are sealed with a flexible, water-resistant silicone to keep mop water out.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Different surfaces, different methods
Thresholds
Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.
Skirting boards
Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing so the new sealant bonds.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Cracked or broken concrete slabs
- Water getting under the tiles from elsewhere
- A tiled floor that needs relaying
Not sure which it is? You can call 07833 053749 or drop us an email and we will tell you honestly before booking.

Quotes for floor joint sealing in Selsdon
We do not publish a price list, because no two jobs are the same. What we look at:
- The type of sealant required
- The number of rooms or windows
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- A few photos by email, if you can
- Roughly how big the job is
- What’s wrong with the joints now
- The address or postcode of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Walk round the room once a year and look at the edges
- Cone off fresh joints until they’re ready
- Get cracks along tile grout lines looked at early
- Use furniture pads near skirting
Silicone sealant isn’t made to take paint. If you plan to paint, we will use a paintable product.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
If you manage several properties in or around Selsdon, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Joints and finishes in Selsdon homes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. 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’s why the skirting and threshold joints need a flexible seal.
Letting a property close to Sanderstead station? Then gaps at skirtings and thresholds are worth sealing between tenancies. Managing a site like Selsdon Primary and Nursery School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
