Floor joint sealing in Hackney Wick
Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. If you have threshold joints that have opened or worn and grout cracking in a straight line across a floor, we can put it right, on skirting boards, wet room & bathroom floors and thresholds alike.
New flats are going up across London, many of them 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.
Each job carries a 12-month guarantee, large or small.

Surface by surface
Skirting boards
Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking in a colour to suit.
Concrete floor joints
Hard wheels break down the edges of open joints. Sealing them supports the edges and stops debris collecting.
Floor joint sealing in Hackney Wick: local notes
Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
Rented homes near Hackney Wick station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. Managing a site like Mossbourne Riverside Academy? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.

Why deal with it now?
Putting new grout into a crack that keeps reappearing does not last. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most rooms, longer for large commercial floors. 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.
- First we check the joint and the floor and agree which sealant suits it.
- We take out any old caulk, sealant or grout along the line.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- The sealant goes in, chosen for the floor and coloured to suit it.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

When to call us in Hackney Wick
Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting, then close again in damper months.
The problems people normally mention when they call include:
- Floor edges that trap water and grime
- Gaps opening between the floor and skirting
- Grout used at the floor edge instead of sealant
- Failed seals where bathroom floors meet baths and panels
If you look after a church, hall or community building such as St Mary of Eton, joints in its floors, skirtings and thresholds need resealing as they wear.
What your quote should include
- What the cure time is
- Whether you can choose the colour
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
DIY sealant or a professional job?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Is parking an issue for floor joint sealing in Hackney Wick?
Parking in Hackney Wick, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
How do I get a quote for floor joint sealing in Hackney Wick?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or email us and let us know what needs doing and where.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Why does the gap under my skirting keep coming back?
Floors shrink and settle, especially in the first year or two and through the heating season. Caulk tends to crack; a flexible sealant does not.
Do you work in Hackney Wick?
Yes. We work in Hackney Wick and the rest of Greater London. For a quote, ring 0345 464 0079 or drop us an email.
How long does floor joint sealing take?
It depends on the size of the job, but as a guide it takes a morning or an afternoon for most homes. We’ll tell you when we quote.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
