Expansion joint sealing in Gerrards Cross, done properly
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. 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. If you are dealing with weathered movement joint sealant that no longer flexes and arrises breaking up along floor joints, we can help. For commercial sealant work in Gerrards Cross, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around places the size of Gerrards Cross, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Check joints after long freezing spells
- Keep stones and debris out of open joint lines
- Avoid parking heavy plant or pallets on joint lines
- Leave barriers in place until fresh joint sealant has cured
Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We’ll tell you which movement joints need doing now and which can wait.
Doing it in-house
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.
Putting right a botched joint often costs more than sealing it well at the start, 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.
What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Crumbling edges that would give a new bead nothing sound to grip
- Movement on a scale no sealant is meant to absorb
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Common questions from Gerrards Cross clients
Will our site in Gerrards Cross have to close for joint sealing?
Rarely. Work is phased around your operations. The phasing plan comes with the quote.
Can you work on a hospital site such as Spire Thames Valley Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What will the job cost?
There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Does the weather affect joint sealing?
Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Internal floor joints are far less affected.
What we are called out for in Gerrards Cross
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.
Common reasons buildings call us in:
- Torn sealant in brick or block movement joints
- Layers of sealant in a movement joint
- Water getting into the wall through a failed joint
- Water dripping through deck or ramp joints
For estates staff at a university like Buckinghamshire New University (3.8 miles south-east of Gerrards Cross), building and paving joints are part of the planned maintenance list.

How a job runs
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Work in places the size of Gerrards Cross is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed
- Arrange parking or a loading space
