Expansion joint sealing in Britwell
Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. If you have chipped joint edges on forklift routes and new sealant over old, now failing, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Britwell tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Small units near places like Britwell are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

How the job changes by surface
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Work in places the size of Britwell is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- 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 tell you if the design looks wrong for the movement.
- 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.
- 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
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed
- Point out any areas we must not close

Your questions answered
Is Britwell off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Is Slough Trading Estate, near Britwell, within your area?
Yes, sites like Slough Trading Estate are within our area, along with the rest of Britwell. A few photos and the unit address let us price the work.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Why has the sealant in our expansion joints split?
Typically the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.

General trades versus a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Floors, slabs and movement joints in Britwell

Aftercare for building managers
Regular inspection catches problems early. In particular:
- Reopen bays and walkways only after the stated cure time
- Plan racking layouts so feet don’t land on a joint
- Include every elevation and deck joint in periodic inspections
- Check joints after long freezing spells
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.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.
Do you need expansion joint sealing in Britwell?
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.
Any of the following is a good reason to get the joints checked over:
- Expansion joints filled with dirt and stones
- Spalled or broken joint edges in floors and decks
- Damp inside where a wall movement joint has failed
- Sealant peeling off one face of the joint
Estates like Slough Trading Estate (1 mile south of Britwell) combine warehouse slabs, yards and loading bays, all with joints under wheels.
What your quote should include
- Can the work be phased to keep areas open?
- How the existing material will be dealt with
- The terms of the workmanship guarantee
- Whether their applicators hold CSCS cards
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Damaged metal nosings or cover plates over a joint
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
