Expansion joint sealing in Merton Park, done properly
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we’ll say so before sealing, and phased work keeps areas in use. Site teams most often ask us about water dripping through deck or ramp joints and joints where the bead has lost adhesion, across blockwork control joints, car park decks and ramps and brickwork movement joints. For commercial sealant work in Merton Park, you deal with one contact from quote to sign-off, whether it’s one building or several.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. A failed joint lets water and debris in, and the edges soon spall.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Signs you need expansion joint sealing in Merton Park
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.
Common reasons buildings call us in:
- Water dripping through deck or ramp joints
- Arrises breaking up along floor joints
- Joints packed with grit and debris
- Expansion joints split through the centre of the bead
A healthcare site such as St George's Hospital (to the north-east of Merton Park) depends on car parks, ramps and service yards whose joints take traffic all day.
What your quote should include
- The terms of the workmanship guarantee
- Will failed sealant be removed rather than covered?
- The named product and why it was chosen
- Will RAMS and insurance details be available?

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
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.

What sets the cost
Quotes vary with the job. It mainly depends on:
- The total length or number of joints
- Distance, for remote addresses
- Removal of failed or old sealant
- How accessible the joints are
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- How the joints are reached, and at what height
- The product your specification calls for
- Drawings or a marked-up plan, if available
- Any dates the work must fit around
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

FAQs: Merton Park
Do you take on jobs in Merton Park where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.
Is a hospital such as St George's Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Can you work on car park ramps and decks?
Yes. We use a sealant designed for wheel loads and the expected movement.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Are expansion joints and movement joints the same thing?
The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.
Different surfaces, different methods
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
Car park decks and ramps
Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed.
Our process
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and 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. Planning a London job such as one in Merton Park starts with access. Give us the hours we can be on site and we will schedule to suit.
- 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.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- 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
- Tell us which areas need to stay in use
- For older buildings, check the asbestos register before work
- Share your working hours and any access restrictions
