Warehouse floors and decks around Nob's Crook
The 3 miles around Nob's Crook take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Nob's Crook sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
At a retail site such as Cannons Retail Park, 2.7 miles to the south-west of Nob's Crook, trolleys, cages and cars run over floor and slab joints all day. Schools like Colden Common Primary School often have long brick elevations with movement joints that age quietly.

About our expansion joint sealing in Nob's Crook
Brickwork and blockwork walls have vertical movement joints at intervals. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. The enquiries we see most involve expansion joints split through the centre of the bead and layers of sealant in a movement joint, across car park decks and ramps, blockwork control joints and podiums and floor movement joints. Most enquiries from Nob's Crook start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Nob's Crook, 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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Cost factors for movement joints
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Joint width, depth and condition
- How much there is to seal
- How accessible the joints are
- Phasing around occupants
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Sending details for a quote
However big the job, these details speed things up:
- The postcode of the building
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
For a fixed quote, call the office on 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. Our quote form is another easy route.
Common questions from Nob's Crook clients
Would you work within a site like Wessex Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you work at a site such as Wessex Business Park, by Nob's Crook?
Yes, sites like Wessex Business Park are within our area, along with the rest of Nob's Crook. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you reseal car park expansion joints?
Yes. Tell us how the car park is used and which areas must stay open.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure.
Signs you need expansion joint sealing in Nob's Crook
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch.
Clients usually get in touch after noticing something like this:
- Chipped joint edges on forklift routes
- Expansion joints split through the centre of the bead
- Joints where the bead has lost adhesion
- Car park joints leaking onto vehicles below
A healthcare site such as Wessex Hospital (to the west of Nob's Crook) depends on car parks, ramps and service yards whose joints take traffic all day.

Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Nob's Crook, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- 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.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000
- Point out parking and an unloading spot

Related advice
Why it’s worth doing now in Nob's Crook
A torn seal left alone usually gets worse. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. One visit to deal with every failing joint makes more sense than several trips to a place like Nob's Crook, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Why choose Mastic Doctor in Nob's Crook

What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Leaks coming from the membrane rather than the joint seal
- Crumbling edges that would give a new bead nothing sound to grip
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If you’re not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.

When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
