Sealant applicators in Cross in Hand

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. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). If you’re dealing with smeared sealant across finishes from a rushed job and greasy, split joints in a kitchen or tea point, we can put it right. A specialist sealant contractor works differently from a general builder: in Cross in Hand, that means joint design, primers and backing rod as standard.

We price commercial jobs in Cross in Hand from photographs, drawings or a site visit, with the scope listed so everyone knows what’s included.

Work in smaller places such as Cross in Hand tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

On site: what to expect

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, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Cross in Hand, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. First, details come to us: photographs, drawings or a schedule of the areas, or we arrange a site visit.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Why deal with it now?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. Often the fitting is sound and the joint is the only thing letting it down. A careful reseal is a far smaller undertaking than replacement. Around Cross in Hand, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why appoint us

  • One phone line for London, the South East and Scotland
  • CHAS accredited
  • Standard and matched colours in many product ranges
  • Colour agreed before work starts

Take a look at what affects the cost or our accreditations.

Commercial clients in Cross in Hand

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Surface by surface

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.

Shop fronts and retail fit-outs

Shop fits put sealant right in front of clients. Joints around counters, displays and shopfront frames have to look tidy as well as seal. Colour options are confirmed with the quote.

Questions about Cross in Hand

Will you take on work at estates like Station Road Industrial Estate, close to Cross in Hand?

Yes, sites like Station Road Industrial Estate are within our area, along with the rest of Cross in Hand. Photos and a short description are enough for a first look.

Can you match sealant colours for premises in Cross in Hand?

Yes, we can normally get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Can you take on work for an FM or managing agent?

Yes. A large share of our work comes through facilities managers, managing agents and landlords as well as contractors. Tell us how you issue work and we will fit in.

Is the old sealant taken out first?

Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.

How long does a typical visit take?

That varies with the scale of the job, but the work typically takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we’ll set out a timescale with the quote.

Could the old sealant in an older building contain asbestos?

Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested.

What sets the cost

What shapes the price:

  • The site’s rules and procedures
  • The product specified
  • Joint width, depth and condition
  • Quantities, in metres or numbers

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Asbestos survey details if the building is older
  • The site address and postcode
  • A wide shot and a close-up of the area
  • How the joints are reached, and at what height

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, call 01277 525 020 or send photos by email.

When to call us in Cross in Hand

Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.

Any of the following is a good reason to get the joints checked over:

  • A top-up bead over failed sealant, now lifting
  • Sanitary sealant that has gone black and patchy
  • Water staining near frames, panels or ceilings
  • Shrunken sealant along kitchen worktops and splashbacks

Occupiers with premises at both Station Road Industrial Estate and Ghyll Road Industrial Estate could have the sealant at each handled under one quote.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • How they’ll work around occupants
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Do they follow the manufacturer’s priming guidance?
