Need commercial sealant contractors in Queen's Park?

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

Keeping the joints sound

A few simple habits keep the new joints working:

  • Check sealant as part of routine building inspections
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Have extract fans checked so wet areas dry out
  • Keep barriers up until the new sealant has cured

Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces.

Once sealant fails in a movement joint, grit and debris get in. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.

Commercial sealant contractors in Queen's Park

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested, and we don’t remove asbestos-containing materials ourselves. If you have earlier reseals applied straight onto the failed bead and frame mastic that has hardened and come away from the wall, we can help, whatever the surface. Looking for mastic applicators who cover Queen's Park? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

On a typical commercial building in Queen's Park, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.

Buildings in a London area such as Queen's Park rarely close for maintenance: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us, and where a brand finish matters, the sealant colour is agreed first.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Surface by surface

Movement joints in walls and floors

Movement joints in walls and floors let the structure expand and contract. When the seal fails, debris gets in and the joint stops working. The new sealant is chosen for the movement and, on floors, the traffic.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Water from a services leak rather than a joint
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly.

Where we work in Queen's Park

  • Window and door perimeters
  • Washrooms and tea points
  • External facade joints
  • Kitchen worktops and splashbacks
  • Floor and threshold joints
  • Movement joints in walls and floors

Quoting for work in Queen's Park

Your fixed quote is built from the real scope. It takes account of:

  • The site’s rules and procedures
  • How much there is to seal
  • Joint width, depth and condition
  • How much existing material needs removing

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Details that help us quote

A few photos plus some basic facts will normally do. Please tell us:

  • The site address and postcode
  • Rough lengths or quantities, or drawings if you have them
  • Whether the building will be occupied during the work
  • Access details, including height

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email us.

Queen's Park: questions and answers

Must a hotel around Queen's Park close while you work?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Do you cover business parks and estates near Queen's Park, such as The Quadrant Business Centre?

Yes. We cover Queen's Park and the area around it, including industrial estates, business parks and retail parks such as The Quadrant Business Centre. Photos and a short description are enough for a first look.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is the old sealant taken out first?

Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Will you just go over the old sealant?

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.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. In Queen's Park, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Share your working hours and any access restrictions
  • Make sure the joints can be reached
  • Have the specification and drawings to hand

Sealant on show in Queen's Park’s commercial buildings

Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We work within them, one zone at a time. Queen's Park has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.

On a business park such as The Quadrant Business Centre, 0.5 miles north-west of Queen's Park, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. Sites a few miles apart, such as The Quadrant Business Centre and Mitre Bridge Industrial Estate, can share one programme and one point of contact. In a retail centre such as O2 Centre, which lies north-east of Queen's Park, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.

Queen's Park is about 2 miles south-west of Hampstead, in Greater London. If you are looking for commercial sealant contractors in Queen's Park, we can help. Across Greater London, 764 places are covered, Queen's Park among them.

If your building is just outside Queen's Park, we cover Kilburn (1 mile north), Kensal Rise (1 mile west), Kensal Town (1 mile south-west), Brondesbury (1 mile north) and Kensal Green (1 mile west). A short drive away, we cover London (5 miles south-east), City of Westminster (3 miles south-east), Marylebone (3 miles south-east), St Pancras (4 miles east), Shoreditch (5 miles east) and Walthamstow (9 miles north-east).
