Questions we are asked in Grahame Park
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly.
Does your area include sites such as Mill Hill Industrial Estate, near Grahame Park?
Yes. Estates, retail parks and business parks around Grahame Park, Mill Hill Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can you work on car park ramps and decks?
Yes. Tell us how the car park is used and which areas must stay open, and we will plan the phasing around it.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Do you need to see the site first?
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.
Expansion joint sealing in Grahame Park, done properly
Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. We work on cladding panel joints, brickwork movement joints and podiums and floor movement joints, and the usual reasons a site gets in touch are chipped joint edges on forklift routes and joints where the bead has lost adhesion. Most enquiries from Grahame Park start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Grahame Park, as everywhere in London, access, loading and the ULEZ all come into the plan.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in Grahame Park
Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. A sealant that isn’t trafficable won’t last there.
Site and facilities staff are often the first to spot these:
- Movement joints with split or torn sealant
- Layers of sealant in a movement joint
- Hardened, cracked sealant on exposed facades
- Water dripping through deck or ramp joints
For an estate such as BMI Hendon Hospital, 0.9 miles to the south-east of Grahame Park, the joints in ramps, decks and long building elevations all need attention over time.
What your quote should include
- How they handle RAMS and site documents
- The named product and why it was chosen
- Will CSCS-carded applicators be on site?
- Can the work be phased to keep areas open?
When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Cracking or settlement that calls for an engineer’s assessment
- 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 in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think before you book.
What we seal
- Brickwork movement joints
- Blockwork control joints
- Precast concrete panel joints
- Podiums and floor movement joints
- Car park decks and ramps
- Cladding panel joints
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Leave barriers in place until fresh joint sealant has cured
- Put movement joints on the planned maintenance inspection round
- Note which joints were done, when, and with what
- Keep stones and debris out of open joint lines
Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can give us a call on 01277 525 020 or use the quote form and send a picture.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
What happens if it’s left?
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. Getting scaffold, permits or access booked in Grahame Park takes effort, so it makes sense to deal with every failing joint while access is in place.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

For estates staff at a university like Middlesex University, less than half a mile south of Grahame Park, building and paving joints are part of the planned maintenance list.

How a job runs
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- 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
- Let us know about inductions and permits
- Clear stock, furniture or equipment away from the joints
- Share your working hours and any access restrictions
