Joints that move: notes for Platt
Platt sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in. Central London is about 23 miles from Platt. The roads out of London are lined with trade parks and distribution sheds.
At places like Invicta Business Park (1.2 miles north of Platt), joints are sealed a section at a time so operations carry on. Parks like Bourne Enterprise Centre (0.8 miles west of Platt) combine paved areas, car parks and building elevations, each with joints that move. In a school such as Platt Church of England Voluntary Aided Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

About our expansion joint sealing in Platt
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. If you are dealing with debris jammed in movement joints and water getting into the wall through a failed joint, we can put it right, on brickwork movement joints, podiums and floor movement joints and precast concrete panel joints alike. Most enquiries from Platt start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Platt, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Building owners, agents and FMs in Platt
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Why it’s worth doing now in Platt
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now, as damage continues meanwhile. We can split the scope into urgent and planned. Converted and older buildings near places like Platt tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Diagnose, treat, sign off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. Smaller jobs around Platt can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
Getting the site ready
- Agree which areas must stay open
- Flag any permit to work we will need

Questions about Platt
Is Platt too far out for you?
No. Places such as Platt are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does your area include sites such as Bourne Enterprise Centre, near Platt?
Yes. Estates, retail parks and business parks around Platt, Bourne Enterprise Centre among them, are all within reach. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
How long will the joint resealing take?
The metres of joint, the access and the amount of removal decide it. Typically it takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Do the joint edges need to be sound before sealing?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
What else we do in Platt
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Removal of failed or old sealant
- The total length or number of joints
- Joint width, depth and condition
- Any access equipment needed
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- The postcode of the building
- Clear photos of the problem areas
- Anything awkward about access or site hours
- The product your specification calls for
To get a fixed quote, speak to us on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.
Doing it in-house
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, which is what makes a joint last.
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.
Honest limits
Honesty saves time and money. New sealant won’t cure:
- Crumbling edges that would give a new bead nothing sound to grip
- Leaks coming from the membrane rather than the joint seal
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If you are not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.
