Expansion joint sealing in Southgate
Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. If you are dealing with sealant pulling off the joint face and layers of sealant in a movement joint, we can help, on precast concrete panel joints, blockwork control joints and cladding panel joints alike. For commercial sealant work in Southgate, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Southgate, as everywhere in London, access, loading and the ULEZ all come into the plan.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

On site: what to expect
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Planning a London job such as one in Southgate starts with access. Give us the hours we can be on site and we will schedule to suit.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- 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.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- Share your working hours and any access restrictions
- Share the asbestos register for older buildings
- Tell us what induction or permit system the site runs

Related advice
Leave it or put it right?
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too, and a second visit means paying for access again. Where it helps, we quote both options. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Why us?
- Colours chosen to suit frames, cladding or finishes where possible
- A Constructionline member, so easy to vet
- Joints cleaned back to sound surfaces
- Workmanship guaranteed for 12 months

What affects the price in Southgate
The price varies from site to site. It mainly depends on:
- Quantities, in metres or numbers
- Location, for remote and island sites
- The size and state of each joint
- Whether old sealant has to be cut out first
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- The postcode of the building

Surface by surface
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it.
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement.
Honest limits
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- A joint that has to be widened or re-detailed before it can work
- Crumbling edges that would give a new bead nothing sound to grip
- Waterproofing layers buried beneath the sealant
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
Surfaces we seal
- Car park decks and ramps
- Precast concrete panel joints
- Blockwork control joints
- Podiums and floor movement joints
- Cladding panel joints
- Brickwork movement joints
Common problems we fix in Southgate
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
Typical triggers for a call:
- Arrises breaking up along floor joints
- Expansion joints filled with dirt and stones
- Car park joints leaking onto vehicles below
- New sealant over old, now failing
Hospitals like Priory Hospital, 0.7 miles to the north-east of Southgate, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Floors, slabs and movement joints in Southgate
Southgate has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Basement car parks and service yards in London tend to be in use all working day, so the work is broken into short sections agreed with the building manager.
For a school such as Ashmole Primary School, playground and building joints can be done in the holidays. If you manage units on an estate such as Brunswick Industrial Estate (0.7 miles south-west of Southgate), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Your questions answered
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for
Do you cover business parks and estates near Southgate, such as Brunswick Industrial Estate?
Yes. We cover Southgate and the area around it, including industrial estates, business parks and retail parks such as Brunswick Industrial Estate. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
What guarantee do you give on joint sealing?
A 12-month guarantee covers our workmanship. Regular sweeping and inspection help the joints last.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
