Surface by surface
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
Podium joints
Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.
Where floor joints take the most wear near Danesfield
Two named trading, business or retail sites lie within about 3 miles of Danesfield. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Danesfield sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and gritting in cold spells finds its way into open joints.
Hospitals like Marlow Community Hospital, 2.5 miles north-east of Danesfield, have multi-storey or surface car parks whose joints carry vehicles round the clock. Phasing is what makes joint work possible on busy sites such as Rashleighs Business Centre (2.9 miles south-east of Danesfield): one bay, aisle or car park row at a time.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
Not sure which it is? You can call 01277 525 020 or email the details over and we will tell you honestly before you book.

Why it’s worth doing now in Danesfield
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. Tell us what has to stay open and we will plan around it. Converted and older buildings near places like Danesfield tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Looking after the joints
To get the most from the new sealant:
- Treat a small split as a warning, not a cosmetic issue
- Avoid parking heavy plant or pallets on joint lines
- Inspect exposed joints once the cold weather has passed
- Clear dirt from joint lines during routine cleaning
Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.
On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. That water often carries de-icing salts with it. Resealing early limits the damage.
FAQs: Danesfield
Does your area include sites such as Globe Business Park, near Danesfield?
Yes, sites like Globe Business Park are within our area, along with the rest of Danesfield. Photos and a short description are enough for a first look.
Is hospital work, at somewhere like Marlow Community Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a quote.
Can you seal joints in cold or wet weather?
A wet joint can’t be sealed properly. The work is simply moved to the next suitable day.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
What causes movement joint sealant to fail?
Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.
Do you offer coloured sealant?
It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
When to call us in Danesfield
The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.
Typical triggers for a call:
- Spalled or broken joint edges in floors and decks
- Movement joints with split or torn sealant
- Damp inside where a wall movement joint has failed
- Car park joints leaking onto vehicles below
Schools such as Danesfield School have movement joints in their walls and floors that are easy to overlook.

Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. For a building around Danesfield, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Let us know about inductions and permits
- Make sure the joints can be reached
- Agree which areas must stay open
