Surface by surface
Brickwork and blockwork joints
Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies before the bead goes in.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.
Our process
Working in a building that stays open takes some planning. 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. Rural sites near Astwood may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
Getting the site ready
- Warn occupants and staff about the work
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space

Advice
When to call us in Astwood
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.
Things that normally lead to an enquiry:
- Spalled or broken joint edges in floors and decks
- Sealant peeling off one face of the joint
- Water getting into the wall through a failed joint
- Expansion joints filled with dirt and stones
Hospitals like Bedford Hospital, 5.9 miles to the east of Astwood, have multi-storey or surface car parks whose joints carry vehicles round the clock.
Before you book anyone

- Will failed sealant be removed rather than covered?
- Do they follow the manufacturer’s priming guidance?

Traffic, movement and joints around Astwood
Astwood is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint. Astwood is about 48 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.
University campuses such as Cranfield University (3.2 miles south of Astwood) have car parks, paved walkways and building elevations with movement joints.

Leave it or put it right?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. Halls, stores and units around places like Astwood may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Looking after the joints
To get the most from the new sealant:
- Keep product details with the building records for the next reseal
- Inspect movement joints alongside other routine building checks
- Avoid parking heavy plant or pallets on joint lines
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.

What else we do in Astwood
Doing it in-house
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Questions we are asked in Astwood
Is a smaller place like Astwood outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Must our site in Astwood stop work while the joints are done?
Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.
How long does movement joint sealing take?
It usually takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, with phasing where areas must stay open. We will confirm when each area can be used again.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Can you work on car park ramps and decks?
Yes. Tell us how the car park is used and which areas must stay open and we’ll plan around them.
