Floor joint sealing in Lake End, done properly
It isn’t only heavy industry. Retail units, showrooms and trade counters have slab joints crossed by trolleys, footfall and cleaning machines, and an open, grimy joint line looks poor as well as catching wheels. A neat, flush fill makes the floor easier to clean and look after. We work on forklift and pallet-truck routes, joints along racking aisles and saw-cut induced joints, and the failures we’re asked to look at most are flexible sealant torn out by wheels and a gap opening alongside old joint filler. Most enquiries from Lake End start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
In and around smaller places like Lake End, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

After the work
After handover, a little attention goes a long way:
- Expect fillers on young slabs to need a top-up
- Put loading bays at the top of the list
- Check joint lines on busy aisles regularly
- Respect the cure time before traffic returns
On younger slabs, a fine line can open down one side of a filled joint as the concrete keeps shrinking. It is a known trait of new floors and a later top-up deals with it in most cases.
Joints are easiest to look after when someone checks them regularly. We can quote a programme that starts with the busiest areas so nothing is left to fail.
What happens if it’s left?
Broken joints shake trucks, stock and operators alike. Wheels and bearings wear faster and loads can shift, which nobody budgets for. A filled joint takes most of that out. One visit to deal with every failing joint makes more sense than several trips to a place like Lake End, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Questions about Lake End
Is hospital work, at somewhere like Upton Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Lake End too small for you to travel to?
No. Places such as Lake End are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.
Can you fill joints where the arrises have spalled?
We check the edges as part of the survey. Damaged edges are flagged up front, so nothing is filled that won’t hold.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What sets the cost
A fixed quote reflects the actual work. It allows for:
- The product specified
- The size and state of each joint
- Any access equipment needed
- Removal of failed or old sealant
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- The site address and postcode
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- Clear photos of the problem areas
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or send photos by email.
Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Our process
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Lake End can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- A fixed quote follows, listing the treatment for each area and the order of work.
- We remove failed material and packed debris until sound concrete is exposed on both faces.
- Dust is extracted from the joint and primer applied where the manufacturer specifies it.
- The chosen product is placed to its specified depth and trimmed level with the floor.
- We tell you when each zone can carry trucks again and move on to the next.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Let us know about inductions and permits
- Point out parking and an unloading spot

Joints near dock doors see colder air, rain blown in and water off vehicles, as well as the tightest turning loads. They are often the first on a site to break down.
If one of these sounds familiar, it’s time for a closer look:
- Joint fill separating from the concrete
- Soft sealant dragged out of trafficked joints
- Drivers complaining about joints on a route
- Cracked and crumbling joint fill
For buildings at a park such as Bray Business Centre (1.1 miles west of Lake End), brick and panel movement joints are easy to forget until one leaks.
