How we handle floor joint sealing in Seven Sisters
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. Common call-outs are for skirting caulk that keeps splitting and gaps at thresholds between rooms, across skirting boards, tiled floors and concrete floor joints.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in Seven Sisters and beyond.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Quotes for floor joint sealing in Seven Sisters
For a quick quote, just ask. What matters most is:
- Access and height
- Mould in or behind the old joints
- The type of sealant required
- The old material and how stubborn it is
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- The address or postcode of the job

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Honest limits
New sealant can’t fix everything, and we’ll tell you before we start. It won’t solve:
- Bouncy or failing floorboards
- Structural movement or subsidence
- Water getting under the tiles from elsewhere
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.
Joints and surfaces we work on
- Skirting boards
- Wet room & bathroom floors
- Commercial floors
- Tiled floors
- Thresholds
- Concrete floor joints
Leave it or put it right?
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In a flat in Seven Sisters, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

New homes and floors in Seven Sisters
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. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
For landlords with property near Seven Sisters station, gaps at skirtings and thresholds are worth sealing between tenancies. For site and facilities teams at buildings such as Earlsmead Primary School, entrance and corridor floor joints take a lot of traffic. If you look after a church, hall or community building such as Church of Holy Trinity, floor and skirting joints in halls and kitchens wear like any others.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Seven Sisters: your questions answered
Is parking an issue for floor joint sealing in Seven Sisters?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.

Why has a gap opened under my skirting?
Timber floors and skirting shrink and swell through the year. We close it with a flexible sealant that moves with the floor.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is caulk good enough for skirting?
Because caulk cracks where there’s movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Get cracks along tile grout lines looked at early
- Check the sealant is paintable before decorating
- Avoid caulk in bathrooms and kitchens
- Look at floor joints each spring
Keep off the joint for the time we give you. Feet are normally fine before mopping or wheeled traffic, and we will tell you both.
Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.
