Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Treat a small split as a warning, not a cosmetic issue
- Include every elevation and deck joint in periodic inspections
- Keep stones and debris out of open joint lines
- Check joints after long freezing spells
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.
Expansion joint sealing in Agar Town, done properly
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors. If you are dealing with hardened, cracked sealant on exposed facades and water dripping through deck or ramp joints, we can help, on blockwork control joints, brickwork movement joints and car park decks and ramps alike. For commercial sealant work in Agar Town, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Agar Town means thinking about access, loading times and the ULEZ as well as the joints.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What else we do in Agar Town
Traffic, movement and joints around Agar Town
Basement car parks and service yards in London tend to be in use all working day, so joints are sealed in sections with each area handed back once cured. Agar Town has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
At places like Hannover Industrial Estate, which lies north-east of Agar Town, joints are sealed a section at a time so operations carry on. Hospital campuses such as St. Pancras Hospital, under half a mile to the south of Agar Town, grow in stages, leaving movement joints wherever new blocks meet old. Retail centres such as Brunswick Centre, 1.1 miles to the south of Agar Town, have floors, service yards and car parks with joints under constant traffic.

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Changing the joint layout or spacing of a structure
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly.

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. In Agar Town, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Share the asbestos register for older buildings
- Confirm the product named in the specification

Why act early in Agar Town
Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open without shutting the whole car park. Tell us what has to stay open and we’ll plan around it. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
A quote for movement joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
Why appoint us
- Standard and matched colours in many product ranges
- Specification-led, product-correct work
- A Constructionline member, so easy to vet
- 12-month guarantee on workmanship

Common questions from Agar Town clients
Can you work at a site such as Roman Way Industrial Estate, by Agar Town?
Yes. Our area takes in Agar Town and its surroundings, with estates and business parks such as Roman Way Industrial Estate included. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
