How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Arrange parking or a loading space
- Warn occupants and staff about the work
- Point out any areas we must not close

Why it’s worth doing now in Balham
Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. In Balham, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
A quote for movement joints depends on quantities, condition and access. Call for a quote.

Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Your questions answered
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Can you take on a job at a hospital such as Springfield University Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you seal joints in cold or wet weather?
A wet joint can’t be sealed properly so we’d rather rearrange than seal in the rain. We agree a revised date with you.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you work while the building is occupied?
Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Avoid parking heavy plant or pallets on joint lines
- Treat a small split as a warning, not a cosmetic issue
- Inspect exposed joints once the cold weather has passed
- Keep stones and debris out of open joint lines
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
