Floor joint sealing for homes and businesses in Tufnell Park
Good floor joints come down to the right product and clean, prepared edges. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We work on skirting boards, thresholds and commercial floors, and the jobs we see most are gaps between floors and kitchen plinths and rigid edge joints in tiled floors.
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.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Why it’s worth doing now in Tufnell Park
Dirt builds up in open joints and makes the floor look worn. Sealed joints are easier to keep clean. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Tufnell Park, the repair is bigger than a sealant job.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Tufnell Park questions
Is Tufnell Park in your area for floor joint sealing?
Yes. Our work covers London and the South East, and Tufnell Park is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Is parking a problem for a job in Tufnell Park?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
How much does floor joint sealing cost in Tufnell Park?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Will I be able to paint over the new joint?
Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone isn’t made to be painted, so it’s kept for wet areas and unpainted joints.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A DIY attempt does not rule out a professional job. We cut it out and start again.
What affects the quote in Tufnell Park
The price is agreed before any work begins. It takes into account:
- How many rooms, windows or areas are involved
- The type of sealant required
- The size of the job
- How easy the joints are to reach
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work and give you a clear price.
When to call us in Tufnell Park
New floors settle once they’re in use. Gaps at the edges appear in the first year or so and anything rigid cracks.
Keep an eye out for any of the following:
- Skirting that has pulled away from the floor
- Chipped and open joints in warehouse floors
- Threshold joints that have opened or worn
- Grout cracking in a straight line across a floor
If you let a flat or house near Upper Holloway station, gaps at skirtings and thresholds are worth sealing between tenancies.
What to look for in a quote
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
- Who turns up on the day
- What the cure time is
How the visit works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for most rooms, longer for large commercial floors, depending on how much there is to do. In Tufnell Park, 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.
- We apply the sealant in a colour that suits the floor.
- The joint is tooled neatly and the cure time explained.
Before we arrive
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Floor joint sealing around Tufnell Park
Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
If you look after a church, hall or community building such as Church of St Benet and All Saints, joints in its floors, skirtings and thresholds need resealing as they wear. Schools such as Eleanor Palmer Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
