Owners, agents and contractors
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
About our expansion joint sealing in Northumberland Park
We have been sealing expansion and movement joints for over 20 years. Our applicators are CSCS-carded, we are CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. The enquiries we see most involve rain penetration at brick or block movement joints and joints where the bead has lost adhesion, across blockwork control joints, podiums and floor movement joints and precast concrete panel joints. A single leaking joint is often how a building in Northumberland Park first comes to us: we look at the rest while we are there and tell you what we find.
Around Northumberland Park, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Changing the joint layout or spacing of a structure
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.
Joints and surfaces we work on

Where floor joints take the most wear near Northumberland Park
Few London car parks or loading bays can be taken out of use for more than a short spell, which is why we work a few bays at a time. Less than 3 miles from Northumberland Park there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.
At a retail site such as Ravenside Retail Park, 0.8 miles north-east of Northumberland Park, trolleys, cages and cars run over floor and slab joints all day. Hospitals like North Middlesex University Hospital (to the north-west of Northumberland Park) have multi-storey or surface car parks whose joints carry vehicles round the clock. Campuses like University of Portsmouth Walthamstow Campus (2.3 miles south-east of Northumberland Park) mix old and new buildings, with movement joints wherever they meet.
Northumberland Park is about 1 mile north-east of Tottenham, in Greater London. We send applicators to Northumberland Park for movement joints. Our Greater London coverage takes in 764 places. Sites around London have their own page, roughly 7 miles from Northumberland Park.

What else we do in Northumberland Park
Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Brief car park operatives to protect joint lines during winter clearance
- Leave barriers in place until fresh joint sealant has cured
- Inspect movement joints alongside other routine building checks
- Treat a small split as a warning, not a cosmetic issue
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Point out any areas we must not close
- Send your site hours and access windows
- Point out parking and an unloading spot

Advice
Questions we are asked in Northumberland Park
Will you take on work at estates like Compass West Industrial Estate, close to Northumberland Park?
Yes. Estates, retail parks and business parks around Northumberland Park, Compass West Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Can you take on a job at a hospital such as North Middlesex University Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
How long does movement joint sealing take?
Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Timings are set out in the quote, including any phasing.
Are expansion joints and movement joints the same thing?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load while the sealant stops grit and water getting in.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Quoting for work in Northumberland Park
A fixed quote reflects the actual work. It takes account of:
- Access and working height
- Phasing around occupants
- Which sealant the job calls for
- The site’s rules and procedures
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Details that help us quote
It doesn’t need to be a full survey. These details are enough to start:
- Asbestos survey details if the building is older
- What the building is and how it’s used

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or send photos by email.
