About our expansion joint sealing in Merton Abbey
We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic and we name it in the quote. If you have expansion joints filled with dirt and stones and leaks through car park deck joints onto the level below, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Merton Abbey from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around Merton Abbey, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up, so it pays to act early.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally 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. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- 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.
Before we start on site
- Let building users know which areas are affected
- Tell us which areas need to stay in use
- Make sure the joints can be reached

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Include every elevation and deck joint in periodic inspections
- Raise snow-clearing blades over deck joints where possible
- Avoid parking heavy plant or pallets on joint lines
- Inspect exposed joints once the cold weather has passed
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint and we will tell you when each bay or area can reopen. Barriers left in place until then protect the finish.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
Joints that move: notes for Merton Abbey
Less than 3 miles from Merton Abbey there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures.
Another example is Chelsea Fields Industrial Estate, which lies east of Merton Abbey, where floors and yards would be done in stages around the occupiers. Places like Priory Retail Park (to the north of Merton Abbey) put trolleys over floor joints inside and cars over slab joints outside.

Why deal with it now?
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. 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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Surface by surface
Joints between different materials
Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement flagging broken arrises before sealing.
Do you need expansion joint sealing in Merton Abbey?
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.
It’s worth sending us details if you spot any of the following:
- Joints where the bead has lost adhesion
- Expansion joints filled with dirt and stones
- Chipped joint edges on forklift routes
- Torn sealant in brick or block movement joints
Hospitals like St George's Hospital, 1 mile north of Merton Abbey, have multi-storey or surface car parks whose joints carry vehicles round the clock.

FAQs: Merton Abbey
Is a hospital such as St George's Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do you cover business parks and estates near Merton Abbey, such as Priory Retail Park?
Yes, sites like Priory Retail Park are within our area, along with the rest of Merton Abbey. A few photos and the unit address let us price the work.
What do you charge?
Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or email us.
Can a joint be sealed if the edges are broken?
Spalled edges need repairing before a new seal will last. A bead on a broken edge soon lets go.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
