Expansion joint sealing in Lewes, done properly
A movement joint only works while its seal does. Once it fails, water, grit and debris get in. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. Site teams most often ask us about arrises breaking up along floor joints and car park joints leaking onto vehicles below, across cladding panel joints, precast concrete panel joints and podiums and floor movement joints. Searching for sealant specialists in Lewes? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Car parks and yards in towns like Lewes take tyre loads and, in winter, de-icing salt. Catching a joint before its edges break is the simpler route.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Parking and loading for town-centre jobs in Lewes are worth mentioning when you send details. Industrial and business units typically have yard or car park space.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability, 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.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Tell us what induction or permit system the site runs
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

What else we do in Lewes
How the quote is worked out
We price every job individually. The main factors are:
- Site requirements such as inductions and permits
- How much existing material needs removing
- How much there is to seal
- Working within restricted access windows
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Send us:
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- The postcode of the building
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send details through our quote form.
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
What the job involves on each surface
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Close-up photos help us judge the joints or a site visit fills the gaps.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces priming where the maker calls for it.
Your questions answered
Will you take on work at estates like Riverside Industrial Estate, close to Lewes?
Yes, sites like Riverside Industrial Estate are within our area, along with the rest of Lewes. 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.
Does a site in Lewes have to shut while its joints are sealed?
Normally not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
What guarantee do you give on joint sealing?
The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.
Slabs, ramps and loading bays in Lewes
The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint. Lewes has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.
A campus such as University of Sussex (4 miles west of Lewes) has long runs of movement joint in its buildings, decks and paving. On industrial estates such as Riverside Industrial Estate, under half a mile to the east of Lewes, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Phasing is what makes joint work possible on busy sites such as Phoenix Industrial Estate (under half a mile east of Lewes): one bay, aisle or car park row at a time.
Lewes is about 7 miles north-east of Brighton, in East Sussex. Our applicators travel to Lewes for work on movement joints. We work across 308 places in East Sussex, from busy centres to rural villages. Brighton is covered too, around 7 miles from Lewes.
Anyone looking for expansion joint sealing in BN7, BN8, BN6 and RH15 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. For a building on Market Lane, Market Street and High Street or nearby, we can quote for movement joints. Main routes into Lewes include the A26 and A275. If your building is just outside Lewes, we cover South Malling (1 mile north-east), Southover (1 mile south-east), Cliffe (1 mile east), Offham (1 mile north-west) and Hamsey (1 mile north). Nearby towns on our patch include Eastbourne (14 miles south-east), Seaford (8 miles south-east), Hailsham (11 miles east), Crowborough (14 miles north-east), Uckfield (8 miles north-east) and Newhaven (6 miles south). Lewes ranks among the main centres of East Sussex, with offices, shops, schools and other public and commercial buildings.
Landmarks near Lewes
In Lewes, that means premises near Priory School, St Pancras Catholic Primary School and Railway Land and the streets around them. For rail, the closest station is Lewes station, roughly 0.6 miles south-east of the centre. Well-known places in the area include Lewes Victoria Hospital (0.5 miles west) and Museum of Agricultural Bygones (3.9 miles east). Green spaces nearby include Offham Hill and Malling Down.
After the work
A few simple habits keep the new joints working:
- Record the sealant used and the date in the O&M file
- Keep stones and debris out of open joint lines
- Treat a small split as a warning, not a cosmetic issue
- Inspect movement joints alongside other routine building checks
Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors, well after the seal first opened. Catching it early keeps the water outside.
Why deal with it now?
Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. Full removal and preparation is in every quote. In a town such as Lewes, a lot of buildings are older and have been altered over time, and joints where old meets new tend to fail first. Renewing them before water gets in protects the fabric.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
