What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Cracking or settlement that calls for an engineer’s assessment
- A joint that has to be widened or re-detailed before it can work
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
Surfaces we seal
- Podiums and floor movement joints
- Car park decks and ramps
- Precast concrete panel joints
- Cladding panel joints
- Blockwork control joints
- Brickwork movement joints
How we handle expansion joint sealing in Horn Park
Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. Most enquiries involve weathered movement joint sealant that no longer flexes and previous reseals laid over old sealant, across car park decks and ramps, blockwork control joints and cladding panel joints. Most enquiries from Horn Park start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Areas such as a loading bay or car park deck in Horn Park normally have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Owners, agents and contractors
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Horn Park can form part of a wider programme.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
What happens if it’s left?
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we’ll tell you honestly. Failed sealant in a building in Horn Park can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What else we do in Horn Park
What the job involves on each surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
From enquiry to sign-off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Flag any permit to work we will need
- Arrange parking or a loading space
- Send asbestos survey details if the building is pre-2000

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Your questions answered
Is hospital work, at somewhere like Eltham Community Hospital, something you do?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Floors, slabs and movement joints in Horn Park
Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured. The 3 miles around Horn Park take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
At places like Green Lane Business Park (1.7 miles south-east of Horn Park), joints are sealed a section at a time so operations carry on. If you manage units on an estate such as Chiltonian Industrial Estate (0.7 miles west of Horn Park), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Hospital campuses such as Eltham Community Hospital, 1.2 miles east of Horn Park, grow in stages, leaving movement joints wherever new blocks meet old.
