What floor joint sealing looks like in Northumberland Park
Many of London’s new homes are flats in bigger 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.
As a London address, Northumberland Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Lea Valley Primary School, entrance and corridor floor joints take a lot of traffic.

Floor joint sealing in Northumberland Park
Good floor joints come down to the right product and clean, prepared edges. We remove what’s there first, the joint is cleaned and backed where needed, then the new sealant goes in. We work on tiled floors, concrete floor joints and thresholds, and the jobs we see most are cracked grout where a tiled floor needs a movement joint and gaps opening between the floor and skirting.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.

Surface by surface
Commercial floors
Floor joint work in businesses can be planned around your hours. Out-of-hours working can be arranged if the floor is busy.
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is usually better.
The process
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it 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.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- We clean and dry the edges of the joint.
- We apply a flexible sealant suited to the floor and tooled.
- We check the joints and explain the aftercare.
How to prepare
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask before painting over a sealed joint
- Keep floor cleaning water to a minimum at the edges
- Avoid caulk in bathrooms and kitchens
- Look at floor joints each spring
Don’t paint over silicone. If you plan to paint, we will use a paintable product.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
Why act early in Northumberland Park
Dirt builds up in open joints and makes the floor look worn. Sealed joints are easier to keep clean and finishes the floor. In a flat in Northumberland Park, 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.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

My floor grout keeps cracking in a line. Can you help?
Usually, yes. A crack along a grout line often means the floor needs room to move. We replace that grout with a flexible joint.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
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.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
