Your questions about floor joint sealing in Custom House
Is parking an issue for floor joint sealing in Custom House?
Parking in Custom House, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can you help a landlord with a rental near Custom House station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do you work in Custom House?
Yes. We’re based in Crawley and work across South East England, London and Scotland, Custom House included.
Why does the gap under my skirting keep coming back?
Generally it’s movement: timber drying in winter, floors settling, or caulk that cannot stretch. A flexible sealant stays closed as the floor moves.
Is there a guarantee?
Yes. Every job comes with our 12-month guarantee.
Floor joint sealing for homes and businesses in Custom House
Where skirting is painted, we can use a flexible sealant that takes paint. For bathrooms and kitchens, silicone is usually the better choice, which isn’t made to be painted. If you’re dealing with concrete floor joints that have broken down and rigid edge joints in tiled floors, we can help, on skirting boards, commercial floors and wet room & bathroom floors alike.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Vacuum floor joints regularly to stop grit building up
- Check the sealant is paintable before decorating
- Look at floor joints each spring
- Use a well-wrung mop rather than flooding the floor
Avoid flooding the floor when you clean. Less water at the edges helps the joints last.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
Work for landlords, hotels and businesses

The process
When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a morning or an afternoon for most homes. In Custom House, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First, the floor type, the gap and the traffic are checked.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

What floor joint sealing looks like in Custom House
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. The joint at the skirting or threshold has to allow for that.
For landlords with property near Custom House station, a tidy floor and skirting joint helps a rental look ready for the next tenant. Community buildings like St Matthew's Church are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. Custom House is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What happens if it’s left?
Not every floor joint takes the same sealant: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. In a flat in Custom House, failed sealant seldom stays inside your own four walls: 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 each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
