How we handle floor joint sealing in Hainault
Across Hainault, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, since that decides which sealant suits. If you are dealing with chipped and open joints in warehouse floors and dirt and water collecting in open floor joints, we can put it right. Mr Mastic is a specialist sealant company, not a general handyman, so floor joint sealing in Hainault is done by someone who does this every day.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover, in Hainault and beyond.
Every job is covered by a 12-month guarantee.

How we quote for floor joint sealing
We quote each job individually. These are the things that affect it:
- How many rooms, windows or areas are involved
- Which sealant suits the joint

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 07833 053749 or email us and we’ll give you an honest view and a quote.

How the job changes by surface
Thresholds
Threshold joints get a lot of feet, so the sealant has to be tough as well as flexible and tool it flush.
Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. They’re resealed with a product chosen for what runs over them.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most rooms, longer for large commercial floors. For a job in Hainault, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First we check the joint and the floor and agree which sealant suits it.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
How to prepare
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on

Questions from Hainault
Can you do floor joint sealing in Hainault?
Yes. We work across London and the South East, and Hainault is part of that. Just call 07833 053749 or send us an email with a few details of the job, and we’ll send you a clear quote.
Can parking be tricky for a visit in Hainault?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you work on commercial floors?
Yes. We clean out the joints and reseal them with a product suited to the floor. Tell us what runs over the floor and we’ll quote.
Can grout be replaced with sealant on a tiled floor?
Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit, giving the floor room to move.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before we start.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Why act early in Hainault
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, but the movement soon cracks it. A flexible sealant moves with the floor, so the joint stays closed. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

What floor joint sealing looks like in Hainault
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. 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.
If you look after a church, hall or community building such as St Francis of Assisi, joints in its floors, skirtings and thresholds need resealing as they wear. Managing a site like Limes Farm Junior School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. As a London address, Hainault can be tricky for parking: let us know about parking bays, permits or a driveway.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Have a cracking tiled floor checked before tiles break
- Keep dirt out of the joints
- Use furniture pads near skirting
- Walk round the room once a year and look at the edges
Lift furniture rather than sliding it over sealed joints. Sharp edges can cut the sealant.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
