How the job changes by surface
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing and flag any joint that seems undersized.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
Expansion joint sealing for commercial buildings in Selmeston
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. Site teams most often ask us about previous reseals laid over old sealant and damp inside where a wall movement joint has failed, on precast concrete panel joints, car park decks and ramps and podiums and floor movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Selmeston is the same: the right product in a properly prepared joint.
In and around smaller places like Selmeston, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What else we do in Selmeston
When to bring in a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Putting right a botched joint often costs more than sealing it well at the start, 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.
After the work
After handover, a little attention goes a long way:
- Keep stones and debris out of open joint lines
- Avoid parking heavy plant or pallets on joint lines
- Treat a small split as a warning, not a cosmetic issue
- Look over external and deck joints after a hard winter
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Resealing early limits the damage.
Common questions from Selmeston clients
Is Berwick Court Farm Business Park, near Selmeston, within your area?
Yes. Our area takes in Selmeston and its surroundings, with estates and business parks such as Berwick Court Farm Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Selmeston outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Can a joint be sealed if the edges are broken?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we will say so when we quote.
Do you use silicone or polyurethane in movement joints?
We choose a sealant with a movement capability that suits the joint. Where two different materials meet, a hybrid sealant can be the better choice.
Can you work on car park ramps and decks?
Yes, we do. These joints take wheels, salt and water, so product choice matters, and we’ll tell you if any edges need repairing first.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Joints that move: notes for Selmeston
At about 47 miles from central London, Selmeston is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors. Selmeston sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.
Business parks such as Berwick Court Farm Business Park (to the south-east of Selmeston) have car parks, paved areas and long brick and panel elevations, all with movement joints. A healthcare site such as Chailey Heritage Marine Hospital, 5.3 miles to the south-west of Selmeston, depends on car parks, ramps and service yards whose joints take traffic all day.
Selmeston is about 5 miles north of Seaford, in East Sussex. If you are looking for expansion joint sealing in Selmeston, we can help, as we do across East Sussex. We work across 308 places in East Sussex, from busy centres to rural villages. We also cover Brighton, some 12 miles away.
We take on movement joints across the BN26 postcode area, whatever the building. Buildings on The Street and Lewes Road are within our area. We also cover Alciston (1 mile south), Berwick (1 mile east), Ripe (2 miles north), Winton (2 miles south) and Wickstreet (2 miles north-east). Bigger towns within reach include Eastbourne (7 miles south-east), Bexhill-on-Sea (14 miles east), Seaford (5 miles south), Lewes (6 miles west), Hailsham (5 miles east) and Crowborough (14 miles north).
Around Selmeston
Around Selmeston, our work takes us to commercial buildings near The Barley Mow pub and the streets around them. The nearest railway station is Berwick (Sussex) station, roughly 1 mile east of the centre. A little further out are Drusillas Museum (1.8 miles south-east) and Chailey Heritage Marine Hospital (5.3 miles south-west). For a walk, there’s Firle Beacon.
Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- A joint that has to be widened or re-detailed before it can work
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Crumbling edges that would give a new bead nothing sound to grip
If you are not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer.
Joints and surfaces we work on

Common problems we fix in Selmeston
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.
Most enquiries start with one or more of the following:
- Joints packed with grit and debris
- Sealant peeling off one face of the joint
- Previous reseals laid over old sealant
- Spalled or broken joint edges in floors and decks
University campuses such as University of Brighton, 4.1 miles south-west of Selmeston, have car parks, paved walkways and building elevations with movement joints.

Diagnose, treat, sign off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. Rural sites near Selmeston may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.

- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Move anything stored against the joints
