In and around smaller places like Donkey Street, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

How the job changes by surface
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors, with a flexible sealant where movement is larger.
Expansion joint sealing around Donkey Street: points for this area

Central London is about 57 miles from Donkey Street. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.
In and around Donkey Street, the right filler or sealant for each joint depends on the traffic and the movement it takes.

On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and our waste is bagged and taken away as we go. Rural sites near Donkey Street may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Point out parking and an unloading spot
- Flag any permit to work we’ll need

Questions we are asked in Donkey Street
Is Donkey Street too small for you to travel to?
No. Places such as Donkey Street are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Our building in Donkey Street is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
What if the joint edges are damaged?
Broken arrises have to be put right before resealing and we’ll flag every length affected. Sealing over them leads to early failure.
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Leave barriers in place until fresh joint sealant has cured
- Avoid parking heavy plant or pallets on joint lines
- Treat a small split as a warning, not a cosmetic issue
- Include every elevation and deck joint in periodic inspections
Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.
Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall. Keeping the seal sound avoids all of that.
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Leaks coming from the membrane rather than the joint seal
- Concrete or masonry repairs along the arrises
- A joint that has to be widened or re-detailed before it can work
If you’re not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer.
