Common questions from Stocker's Head clients

Is Stocker's Head off your patch?

Not at all. Stocker's Head is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

What documents will you need to give us for a job in Stocker's Head?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What guarantee do you give on resealing?

A 12-month guarantee covers the workmanship. Keeping joints clean and inspected helps them last well beyond that.

Is failed sealant stripped out, or sealed over?

The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.

Do you check for asbestos before removing sealant?

It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.

How long does a job like this take?

That varies with the scale of the job, though a typical visit typically takes anything from part of a day on a short run of joints to several weeks on a large phased package. For bigger or phased jobs, we’ll set out a timescale with the quote.

Sealant applicators in Stocker's Head

Getting a price for commercial sealant contractors in Stocker's Head doesn’t need to be drawn out. Our quote form takes photographs, drawings or a schedule of the areas; you can also phone 01277 525 020 or email us with the details. Where the photographs don’t tell the full story, we arrange a site visit. If you have movement joints packed with grit and debris and frame sealant that has cracked, shrunk or pulled away, we can put it right, on external facade joints, washrooms and tea points and kitchen worktops and splashbacks alike. A single leaking joint is often how a building in Stocker's Head first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In Stocker's Head, as anywhere, the first joints to go are normally the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Business units in the countryside around places like Stocker's Head are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Why act early in Stocker's Head

Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after. Where it helps, we quote a patch and a full reseal side by side. Older rural buildings around Stocker's Head move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing sealant joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Why us?

  • One number for every site we cover
  • Health and safety: CHAS accredited
  • Fixed quotes based on photos, drawings or a visit
  • 12 months’ guarantee on every job

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Stocker's Head, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

How the job changes by surface

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. 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.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Put external and wet-area joints on a regular inspection round
  • Keep a record of which joints were resealed and when
  • Keep barriers up until the new sealant has cured
  • On pre-2000 buildings, share the asbestos information before work starts

Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. If anything looks wrong, call the office on 01277 525 020 or send details through our quote form with a photo.

Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.

What sets the cost

These are the things that shape the price:

  • The total length or number of joints
  • Location, for remote and island sites
  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • Your programme or deadline
  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or use the quote form.
