Where floor joints take the most wear near South Norwood
Basement car parks and service yards in London tend to be in use all working day, which is why we work a few bays at a time. Less than 3 miles from South Norwood there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
Phasing is what makes joint work possible on busy sites such as Franklin Industrial Estate (1.2 miles north-east of South Norwood): one bay, aisle or car park row at a time. Hospitals like Shirley Oaks Hospital (to the south-east of South Norwood) have multi-storey or surface car parks whose joints carry vehicles round the clock. For estates staff at a university like King's College London, which lies north of South Norwood, building and paving joints are part of the planned maintenance list.

South Norwood: questions and answers
Do you cover business parks and estates near South Norwood, such as Chaffinch Business Park?
Yes. Our area takes in South Norwood and its surroundings, with estates and business parks such as Chaffinch Business Park included. Photos and a short description are enough for a first look.
Is hospital work, at somewhere like Shirley Oaks Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
When can forklifts run over new joint filler?
Each product has its own cure time and cooler floors take longer. We plan the phasing so that waiting time fits your operation.
Is colour matching possible?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Why act early in South Norwood
Tape, or whatever sealant is in the stores cupboard, may look like a fix for a while. Neither is made to carry wheels and traffic soon pulls it out. A product chosen for the traffic and movement does the job once. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
A quote for floor joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

How a job runs
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. All of Greater London is in the ULEZ, and kerbside space in South Norwood can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We look at joint widths, edge condition and the traffic on each route.
- A fixed quote follows, listing the treatment for each area and the order of work.
- Old filler, debris and contamination are cut or routed out back to clean concrete.
- Dust is extracted from the joint and primer applied where the manufacturer specifies it.
- The chosen product is placed to its specified depth and trimmed level with the floor.
- The area is handed back once it has cured enough to take traffic.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
- Make sure the joints can be reached
Ask for a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Surface by surface
Semi-rigid joint fillers
A semi-rigid filler is stiff enough to hold the arrises up when wheels cross. They tolerate little movement so timing matters on newer slabs.
Isolation joints at walls and columns
Perimeter and column joints get forgotten and fill up with dirt. We include them in the survey.
For managing agents and facilities managers
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Removal of failed or old sealant
- Location, for remote and island sites
- Induction, permit and paperwork requirements
- The size and state of each joint
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- The site address and postcode
- The type of building and who uses it
- When you need the work done
- Access details, including height
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call 01277 525 020 or email drawings and photos to discuss it first.

Should maintenance staff do it?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
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.
