Floor joint sealing for homes and businesses in Shirley
Painted skirting can be sealed with a flexible product that can be painted over. In wet areas we’d normally use silicone. We work on skirting boards, thresholds and tiled floors, and common reasons people get in touch are grout cracking in a straight line across a floor and caulk that has cracked where the floor moves.
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, in Shirley as anywhere.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

DIY versus a professional finish
If you are 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 fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Leave it or put it right?
Floor joints left open collect dirt that is hard to clean out. A neat sealed joint is easier to clean. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Shirley, the repair is bigger than the sealant job would have been.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Why choose Mr Mastic in Shirley
- An ARBOMaster approved applicator
- We never seal over old sealant

- Sanitary silicone with an anti-fungal additive in wet areas
What the job involves on each surface
Thresholds
Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. Sealing them supports the edges.
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Damaged concrete that needs breaking out and repairing
- Subfloor problems that need a flooring contractor
- Leaks from a failed tanking system
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

Floor joint sealing in Shirley: local notes
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
Shirley is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Oasis Academy Shirley Park, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. For landlords with property near Elmers End station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

What happens on the day
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on the length of joint. 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.
- We look at the gap and the floor type and agree the right sealant.
- We take out any old caulk, sealant or grout along the line.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- The sealant goes in, chosen for the floor and coloured to suit it.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
