Sealant applicators in Headington Quarry

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 (removing asbestos-containing materials isn’t something we do). We work on washrooms and tea points, floor and threshold joints and external facade joints, and the failures we’re asked to look at most are mouldy silicone around WCs, urinals and vanity tops and movement joints packed with grit and debris. Searching for sealant specialists in Headington Quarry? We have been sealing commercial buildings since 2005.

Occupied buildings in Headington Quarry need the work phased: we agree the order with you and hand back each area with its cure time.

Places like Headington Quarry tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. Each job is modest, yet a joint in a small café needs the same cutting out, cleaning and sealing as one in a city office.

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.

Cost factors for sealant joints

The price varies from site to site. It mainly depends on:

  • Phasing around occupants
  • Joint width, depth and condition
  • The total length or number of joints
  • Removal of failed or old sealant

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • The product your specification calls for
  • Any dates the work must fit around

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Common questions from Headington Quarry clients

Is Headington Quarry off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Will our hotel in Headington Quarry need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

What about asbestos in old mastic?

It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Which site documents can you send us?

We confirm documents at quote stage: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.

How is commercial sealant work priced?

Start with whatever information is to hand. Questions or a site visit follow where needed, then a fixed quote.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Work in places the size of Headington Quarry is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  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. A final walk-round, then the 12-month guarantee applies.

Getting the site ready

  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Why it’s worth doing now in Headington Quarry

Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Act on the first lifting edges rather than waiting
  • Note dates and locations of sealant work for future planning
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Look at the sealant around anything that has been moved or replaced

Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces.

Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Different surfaces, different methods

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price, and we will confirm the colours available for the specified product.

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant.
