Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Joints too narrow for the movement, which need redesigning by the engineer
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Waterproofing layers buried beneath the sealant

Expansion joint sealing in Preston Crowmarsh
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors for buildings in Preston Crowmarsh. The enquiries we see most involve sealant peeling off one face of the joint and leaks through car park deck joints onto the level below, across podiums and floor movement joints, blockwork control joints and precast concrete panel joints. Whoever orders the work in Preston Crowmarsh, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a site near Preston Crowmarsh, measurements and photographs up front mean one trip where possible. Note joint widths and the traffic that uses them, and we’ll take it from there.
Every job we finish is backed by a 12-month workmanship guarantee, in Preston Crowmarsh as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the job changes by surface
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed, and we’ll tell you if any edges need repairing first.
Questions we’re asked in Preston Crowmarsh
Can you work at a site such as Hithercroft Industrial Estate, by Preston Crowmarsh?
Yes, sites like Hithercroft Industrial Estate are within our area, along with the rest of Preston Crowmarsh. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.
Is Preston Crowmarsh off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
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 so the same failure isn’t repeated.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Why act early in Preston Crowmarsh
Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme because damage continues. We can split the scope into urgent and planned. For buildings around smaller places like Preston Crowmarsh, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
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.

Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. If others near Preston Crowmarsh need work, visits can be combined. You will have a fixed quote before work starts.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Explain the parking and delivery arrangements
- Tell us what induction or permit system the site runs
- Let building users know which areas are affected

Related advice
After the work
Once the work is signed off, these steps help:
- Keep traffic off new joints until the cure time is up
- Raise snow-clearing blades over deck joints where possible
- Treat a small split as a warning, not a cosmetic issue
- Record the sealant used and the date in the O&M file
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We’ll tell you which movement joints need doing now and which can wait.
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
