How we handle expansion joint sealing in Rusper
Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic, and we’ll confirm the choice in the quote. If you are dealing with expansion joints filled with dirt and stones and new sealant over old, now failing, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Rusper is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a site near Rusper, measurements and photos up front mean one trip where possible. Note joint widths and the traffic that uses them, and we’ll take it from there.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Common questions from Rusper clients
Can you work at a site such as Holmbush Potteries Industrial Estate, by Rusper?
Yes. We cover Rusper and the area around it, including industrial estates, business parks and retail parks such as Holmbush Potteries Industrial Estate. Photos and a short description are enough for a first look.
Would you work within a site like Crawley Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Can the building stay open while you work?
In the majority of cases, yes. Phased work can be planned so areas stay in use.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Slabs, ramps and loading bays in Rusper
Rusper has two named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment. Rusper 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 where de-icing salt is spread in winter, open joints let it in.
For an estate such as Crawley Hospital, which lies east of Rusper, the joints in ramps, decks and long building elevations all need attention over time. For a school such as Rusper Primary School, playground and building joints can be done in the holidays.

After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Plan racking layouts so feet don’t land on a joint
- Note which joints were done, when, and with what
- Check joints after long freezing spells
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file, so the next reseal starts with the facts.
On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
When to call us in Rusper
Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.
Look out for the following:
- Sealant pulling off the joint face
- Arrises breaking up along floor joints
- Joints packed with grit and debris
- Damp inside where a wall movement joint has failed
Phasing is what makes joint work possible on busy sites such as New House Business Centre (2.5 miles south of Rusper): one bay, aisle or car park row at a time.

From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. Jobs in and around smaller places like Rusper are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements
- Flag any permit to work we will need

What the job involves on each surface
Joints between different materials
Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces, with primer where specified.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.
