Expansion joint sealing for businesses in Somers Town

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing in Somers Town

If you need expansion joint sealing in Somers Town, start with photos and joint lengths. Send them through our quote form, and we will arrange a site visit if needed before issuing a fixed quote. To discuss the joints first, call the office on 01277 525 020 or email the details over. Site teams most often ask us about debris jammed in movement joints and car park joints leaking onto vehicles below, on cladding panel joints, precast concrete panel joints and blockwork control joints. A specialist sealant contractor works differently from a general builder: on jobs in Somers Town, preparation and product choice get the time they need.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Somers Town means thinking about access, loading times and the ULEZ as well as the joints.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Expansion joint sealing in Somers Town: the local picture

Somers 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. Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured.

For estates staff at a university like University College London (less than half a mile south of Somers Town), building and paving joints are part of the planned maintenance list. On industrial estates such as Roman Way Industrial Estate, 1.1 miles north-east of Somers Town, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Somers Town is about 1 mile north-west of St Pancras, in Greater London. We send applicators to Somers Town for movement joints. 764 places across Greater London fall within our area, including Somers Town.

Questions we’re asked in Somers Town

Will you take on work at estates like Roman Way Industrial Estate, close to Somers Town?

Yes. Estates, retail parks and business parks around Somers Town, Roman Way Industrial Estate among them, are all within reach. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

Can you take on a job at a hospital such as St. Pancras Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

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.

How do I request a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email the details over. Include photos or drawings if you have them.

What we are called out for in Somers Town

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it.

These are often picked up first by site or facilities staff:

  • Leaks through car park deck joints onto the level below
  • Hardened, cracked sealant on exposed facades
  • Joints where the bead has lost adhesion
  • Rain penetration at brick or block movement joints

Hospitals like St. Pancras Hospital (to the north of Somers Town) have multi-storey or surface car parks whose joints carry vehicles round the clock.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • Health and safety accreditation such as CHAS
  • What the guarantee covers, and for how long
  • Their plan for phasing and protecting the area

Our contractor checklist

What the job involves on each surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.

Car park decks and ramps

Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again, and we will tell you if any edges need repairing first.

What we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Changing the joint layout or spacing of a structure
  • Movement on a scale no sealant is meant to absorb

If you are not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.

Surfaces we seal

  • Cladding panel joints
  • Podiums and floor movement joints
  • Car park decks and ramps
  • Blockwork control joints
  • Brickwork movement joints
  • Precast concrete panel joints

Maintenance after handover

To get the most from the new sealant:

  • Include every elevation and deck joint in periodic inspections
  • Look over external and deck joints after a hard winter
  • Keep product details with the building records for the next reseal
  • Leave barriers in place until fresh joint sealant has cured

Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth and we will tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Sealing early protects the edges.

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on 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. All of Greater London is in the ULEZ, and kerbside space in Somers Town can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Getting the site ready

  • Confirm the product named in the specification
  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed
