Floor joint sealing in Northend, done properly
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. If you’re dealing with cracked grout where a tiled floor needs a movement joint and cracked caulk along skirting in bathrooms and kitchens, we can put it right, whatever the surface.
Around Northend, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Questions from Northend
Is Northend in your area for floor joint sealing?
Yes. We work across London and the South East, and Northend is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.
Will you come out to Northend?

Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Can you use decorators’ caulk instead?
Caulk is fine for dry joints that don’t move, but it splits where the joint moves or gets wet. We use a flexible sealant for most skirting and floor joints.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.

Why it’s worth doing now in Northend
Left open, concrete joints break down under traffic. Resealing it early protects the edges. Where a wall is exposed, as many are in small places like Northend, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Different surfaces, different methods
Tiled floors
When grout cracks along a straight line, the floor is telling you it needs to move. That line is converted to a flexible joint where it suits the floor.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. Sealing them supports the edges and keeps dirt out.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most rooms, longer for large commercial floors. In a small place like Northend, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor and tooled.
- Finally, we check the work and talk you through aftercare.
How to prepare
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
