Expansion joint sealing in Steyning
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Steyning. The enquiries we see most involve hardened, cracked sealant on exposed facades and joints packed with grit and debris, across podiums and floor movement joints, car park decks and ramps and cladding panel joints. Searching for sealant specialists in Steyning? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In a smaller place such as Steyning, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.
We sign every job 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.

Expansion joint sealing around Steyning: points for this area
At about 44 miles from central London, Steyning is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Steyning sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, while winter salting gets into any joint left open.
Estates like Mackley Industrial Estate (2.5 miles east of Steyning) combine warehouse slabs, yards and loading bays, all with joints under wheels. Hospitals like Southlands Hospital, 4.4 miles south-east of Steyning, have multi-storey or surface car parks whose joints carry vehicles round the clock.
Steyning is about 4 miles north-west of Shoreham-by-Sea, in West Sussex. Steyning sits inside our coverage and the rest of West Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in 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. For a site in Steyning, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- We start with photos, 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.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.

Your questions answered
Is Steyning off your patch?
No. Places such as Steyning are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Is Mackley Industrial Estate, near Steyning, within your area?
Yes, sites like Mackley Industrial Estate are within our area, along with the rest of Steyning. Send details of the unit and the work through our quote form for a quick quote.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
What hours do you work?
We are 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.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks typically need a polyurethane, and the specification has the final say.

What the job involves on each surface
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 flagging broken edges along the way.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement, and tell you if edges need repairing first.
Quoting for work in Steyning
The price varies from site to site. Expect it to depend on:
- The total length or number of joints
- Which sealant the job calls for
- Any access equipment needed
- Removal of failed or old sealant
Pricing movement joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.
Before you send an enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- Your programme or deadline
- Any specification or named product
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
For a fixed quote, give us a call on 01277 525 020 or send details through our quote form with the site address and an outline of the work. You can also send details through our quote form.
What happens if it’s left?
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed. In a smaller place such as Steyning, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Damaged metal nosings or cover plates over a joint
- Movement on a scale no sealant is meant to absorb
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think.
Surfaces we seal
- Precast concrete panel joints
- Car park decks and ramps
