Expansion joint sealing in Freemantle
Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. If you have previous reseals laid over old sealant and weathered movement joint sealant that no longer flexes, we can put it right, on blockwork control joints, car park decks and ramps and brickwork movement joints alike. A specialist sealant contractor works differently from a general builder: in Freemantle, that means joint design, primers and backing rod as standard.
Small units near places like Freemantle are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Building owners, agents and FMs in Freemantle
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Freemantle can sit alongside others in a wider programme.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
After the work
Regular inspection catches problems early. In particular:
- Leave barriers in place until fresh joint sealant has cured
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Keep racking legs and heavy point loads off floor joints
- Report split or peeling joint sealant early
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file, so the next reseal starts with the facts.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one. We’ll tell you which movement joints need doing now and which can wait.
Different surfaces, different methods
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, typically low-modulus laid over backing rod at the correct depth.
Podium joints
Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.
How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Any access equipment needed
- Travel to remote or island sites
- The site’s rules and procedures
- How much existing material needs removing
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- The site address and postcode
- Photos of the joints, close up and from further back
- Whether the building will be occupied during the work
- The asbestos register, for older buildings
To get a fixed quote, give us a call on 01277 525 020 or use the quote form. Our quote form is another easy route.
Honest limits
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Damaged metal nosings or cover plates over a joint
- Crumbling edges that would give a new bead nothing sound to grip
- Leaks coming from the membrane rather than the joint seal
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Questions we’re asked in Freemantle
Can you work at a site such as Liners Industrial Estate, by Freemantle?
Yes, sites like Liners Industrial Estate are within our area, along with the rest of Freemantle. Send details of the unit and the work through our quote form for a quick quote.
Is Freemantle off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
How much does the work cost?
There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. What matters most for a job in Freemantle is a clear list of what needs doing, so send photographs of each area. You’ll then get a fixed price for the work.
- We assess the joints on site or from photos, noting widths and how each has failed.
- 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.
What we need from you
- Agree which areas must stay open
- Have the specification and drawings to hand
- Flag any permit to work we will need

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email us.
