How we handle expansion joint sealing in Chithurst
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors on sites in Chithurst. If you’re dealing with car park joints leaking onto vehicles below and new sealant over old, now failing, we can help, on precast concrete panel joints, cladding panel joints and brickwork movement joints alike. Whoever orders the work in Chithurst, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Halls, schools and small commercial buildings near places like Chithurst have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

What the job involves on each surface
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler.

When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Leaks coming from the membrane rather than the joint seal
- Crumbling edges that would give a new bead nothing sound to grip
- Cracking or settlement that calls for an engineer’s assessment
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Surfaces we seal
- Cladding panel joints
- Blockwork control joints
- Car park decks and ramps
- Brickwork movement joints
- Precast concrete panel joints
- Podiums and floor movement joints
Aftercare for building managers
For the best life from the joints:
- Leave barriers in place until fresh joint sealant has cured
- Put movement joints on the planned maintenance inspection round
- Plan racking layouts so feet don’t land on a joint
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one so you can prioritise and budget. We can suggest an order, worst joints first.
On site: what to expect
On arrival, 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 normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Rural sites near Chithurst may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- The failed seal is removed and both faces are cleaned until sound and dry.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- 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.
Getting the site ready
- Agree which areas must stay open
- Warn occupants and staff about the work
- Arrange parking or a loading space

Expansion joint sealing around Chithurst: how the place shapes the job
Chithurst sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. Chithurst lies roughly 46 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London.
Across sites such as Holmbush Industrial Estate, which lies south-east of Chithurst, floor and movement joints can be sealed in phases so units keep working. Hospitals like Midhurst Community Hospital (to the east of Chithurst) have multi-storey or surface car parks whose joints carry vehicles round the clock.
Chithurst is about 6 miles east of Petersfield, in West Sussex. Our applicators travel to Chithurst for work on movement joints. Our West Sussex coverage takes in 373 places. There’s a separate page for Portsmouth, roughly 18 miles from Chithurst.
Commercial sites across GU31 are covered. Just outside Chithurst, we also work in Trotton Marsh (1 mile north-west), Borden (1 mile north-west), Rogate (2 miles west), Milland (2 miles north) and Rake (4 miles north-west). Nearby towns on our patch include Bognor Regis (15 miles south), Chichester (11 miles south), Billingshurst (15 miles east), Portfield (11 miles south), Yapton (15 miles south-east) and Midhurst (3 miles south-east).

Well-known places in the area include Midhurst Museum (2.9 miles east) and Midhurst Community Hospital (2.9 miles east). For a walk, there’s Wheeler's Down and Iping and Stedham Commons.
Why act early in Chithurst
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use without shutting the whole car park. Tell us what has to stay open and we’ll plan around it. For buildings around smaller places like Chithurst, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Common questions from Chithurst clients
Is a hospital such as Midhurst Community Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Chithurst too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Can you work on car park ramps and decks?
Yes. Let us know the opening hours and which levels or bays have to stay available, and we’ll plan the phasing around it.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long does movement joint sealing take?
Expect a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, with phasing where areas must stay open. Cure time before reopening is confirmed on the day.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact.
Signs you need expansion joint sealing in Chithurst
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. The product has to be suited to the traffic.
Clients typically get in touch after noticing one or more of the following:
- Previous reseals laid over old sealant
- Leaks through car park deck joints onto the level below
