Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Coombe can form part of a wider programme across Greater London.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
How we handle floor joint sealing in Coombe
A working floor can rarely be closed for days on end, so the work is split into zones and treated one area at a time. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. Site teams most often ask us about joint fill separating from the concrete and cracked and crumbling joint fill, on saw-cut induced joints, construction joints and forklift and pallet-truck routes. Searching for sealant specialists in Coombe? We’ve been sealing commercial buildings since 2005.
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. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What happens if it’s left?
Some runs only need partial renewal or topping up. If old material is sound on one face and only a fine gap has opened, it may not all have to come out and the quote shows which approach suits each run. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Our process
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Planning a London job such as one in Coombe starts with access. Give us the hours we can be on site and we will schedule to suit.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- A fixed quote follows, listing the treatment for each area and the order of work.
- Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
- Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
- Filler or sealant goes in to the right depth and is finished flush with the slab.
- The area is handed back once it has cured enough to take traffic.
Preparing the site
- Agree which areas must stay open
- Flag any permit to work we’ll need
- Send asbestos survey details if the building is pre-2000

What else we do in Coombe
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Floor joint sealing in Coombe: the local picture
Few London car parks or loading bays can be taken out of use for more than a short spell, which is why we work a few bays at a time. Coombe has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
A healthcare site such as Shirley Oaks Hospital (1.4 miles north-east of Coombe) depends on car parks, ramps and service yards whose joints take traffic all day. Retail centres such as Whitgift Centre (1.6 miles north-west of Coombe) have floors, service yards and car parks with joints under constant traffic. On a site such as Twin Bridges Business Park, 1.2 miles south-west of Coombe, the movement joints are in car park slabs, paving and building elevations.
Coombe is about 1 mile east of Croydon, in Greater London. Any commercial site in Coombe is covered, for single jobs and planned programmes alike. Coombe is one of 764 places we cover in Greater London. Our London page has more on work in that area, about 9 miles away.

Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Hold traffic back until the product has cured
- Clear packed debris from open joints regularly
- Photograph any joint that starts to chip
- Allow for topping up joints as a new slab settles
On younger slabs, a fine line can open down one side of a filled joint as the concrete keeps shrinking. It is a known trait of new floors and a later top-up deals with it in most cases.
Every vehicle on a busy aisle hits a damaged joint. Early treatment protects wheels, loads and drivers as much as the floor.
Coombe: questions and answers
Do you take on jobs in Coombe where loading and access are tightly controlled?
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
