About our expansion joint sealing in Hersham
Brickwork and blockwork walls have vertical movement joints at intervals, 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 with primer where the maker calls for it. We work on car park decks and ramps, brickwork movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are water dripping through deck or ramp joints and water getting into the wall through a failed joint. Most enquiries from Hersham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Rural business units around smaller places such as Hersham often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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. That’s why many clients bring in a specialist from the beginning.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- A joint that has to be widened or re-detailed before it can work
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Do you need expansion joint sealing in Hersham?
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
Look out for the following:
- Rain penetration at brick or block movement joints
- Water dripping through deck or ramp joints
- Joints packed with grit and debris
- New sealant over old, now failing
University campuses such as Kingston University Penrhyn Road Campus, 4.9 miles north-east of Hersham, have car parks, paved walkways and building elevations with movement joints.
What your quote should include
- How the joint faces will be prepared and primed
- Their approach to joint depth and backing
- How they’ll work around occupants
- What level of public liability insurance do they hold?
Aftercare for building managers
Once the work is signed off, these steps help:
- Act on the first tear or lifting edge rather than waiting
- Keep scrapers and ploughs from dragging across joint sealant
- Include every elevation and deck joint in periodic inspections
- Note which joints were done, when, and with what
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’ll tell you when each bay or area can reopen. Barriers left in place until then protect the finish.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We will tell you which movement joints need doing now and which can wait.
Hersham: questions and answers
Is Hersham Place Technology Park, near Hersham, within your area?
Yes. We cover Hersham and the area around it, including industrial estates, business parks and retail parks such as Hersham Place Technology Park. To start, just speak to us on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is Hersham too small for you to travel to?
No. Places such as Hersham 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 the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Can you seal joints in cold or wet weather?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
Traffic, movement and joints around Hersham
Hersham has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Hersham sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.
Another example is Hersham Trading Estate (0.9 miles north-east of Hersham), where floors and yards would be done in stages around the occupiers. Business parks such as Hersham Place Technology Park, less than half a mile south-east of Hersham, have car parks, paved areas and long brick and panel elevations, all with movement joints.
