How we handle expansion joint sealing in Colnbrook
Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on podiums and floor movement joints, blockwork control joints and brickwork movement joints, and the usual reasons a site gets in touch are expansion joints split through the centre of the bead and new sealant over old, now failing. A specialist sealant contractor works differently from a general builder: in Colnbrook, that means joint design, primers and backing rod as standard.
Halls, schools and small commercial buildings near places like Colnbrook have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface
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.
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies.

Some faults sit outside our scope, and we say so rather than covering them up:

- Waterproofing layers buried beneath the sealant
- Damaged metal nosings or cover plates over a joint
If in doubt, call 01277 525 020 or email us and we will say what we think before you book.

Advice
Common problems we fix in Colnbrook
Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way unless width and product are reviewed.
Common reasons buildings call us in:
- Joints where the bead has lost adhesion
- Damp inside where a wall movement joint has failed
- Expansion joints filled with dirt and stones
- Hardened, cracked sealant on exposed facades
For an estate such as Upton Hospital, which lies north-west of Colnbrook, the joints in ramps, decks and long building elevations all need attention over time.

FAQs: Colnbrook
Is a hospital such as Upton Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Is Colnbrook too far out for you?
No. Places such as Colnbrook are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can you seal joints in cold or wet weather?
Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Indoor joints can normally carry on regardless.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
What will the job cost?
Every job gets its own fixed quote. To get one, phone 01277 525 020 or use the quote form with a description of the work.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Redoing a failed joint usually 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.
