Commercial sealant contractors for commercial buildings in Jacob's Post

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. If you have water staining near frames, panels or ceilings and window and door perimeter joints that have cracked open, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Jacob's Post from the first photographs to the final walk-round, whether it’s one building or several.

A lot of what we do in Jacob's Post is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Rural business units near smaller places such as Jacob's Post are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

Our workmanship is guaranteed for 12 months, in Jacob's Post as everywhere else we work. If our installation lets you down in that time, we return and fix it.

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near Jacob's Post need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Preparing the site

  • Warn occupants and staff about the work
  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work

Quoting for work in Jacob's Post

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Working within restricted access windows
  • The total length or number of joints
  • Joint width, depth and condition
  • Location, for remote and island sites

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.

Details that help us quote

We can often quote from photos and a few details. Please tell us:

  • Clear photographs of the problem areas
  • The type of building and who uses it
  • Where the site is, with the postcode
  • How the joints are reached, and at what height

A good quote starts with a clear picture: 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.

Questions about Jacob's Post

Is Jacob's Post too far out for you?

Not at all. Jacob's Post is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is Ashwyn Business Centre, near Jacob's Post, within your area?

Yes, sites like Ashwyn Business Centre are within our area, along with the rest of Jacob's Post. A few photos and the unit address let us price the work.

Does commercial sealant work come with a guarantee?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

Can areas stay open during the work?

That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Let us know what can’t close and we’ll work around it.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What about asbestos in old mastic?

We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder and removing it isn’t something we do.

Do you work directly for building managers?

Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process.

General trades versus a specialist

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 where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Commercial premises in Jacob's Post

Jacob's Post has two care or nursing homes no more than 2 miles away. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean, often in colours that suit the décor. The 3 miles around Jacob's Post take in at least three named trading estates, business parks or retail parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen.

For tenants and agents on sites such as Ashwyn Business Centre (0.5 miles north of Jacob's Post), office fit-outs, reception joints and window perimeters are the usual sealant work. Offices and shops close to stations such as Burgess Hill station (0.7 miles south-east of Jacob's Post) tend to be busy all day, so sealant work is planned around opening hours.

Jacob's Post is about 1 mile west of Burgess Hill, in West Sussex. Anywhere in RH15, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

What happens if it’s left?

On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings. You notice the difference years later, not on the day. For buildings around smaller places like Jacob's Post, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Why us?

  • Work carried out by CSCS-carded applicators
  • A Constructionline member, so easy to vet
  • Old sealant cut out, never sealed over
  • Standard and matched colours in many product ranges

What the job involves on each surface

Shop fronts and retail fit-outs

In retail, sealant is on show. Joints around counters, displays and shopfront frames have to look tidy as well as seal. We will confirm the colours available for the specified product.

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. Failed seals let grit and water in, and the edges start to suffer. The joints are resealed using a sealant matched to the movement and any traffic.

Common problems we fix in Jacob's Post

Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once.

Things that usually lead to an enquiry:

  • Frame mastic that has hardened and come away from the wall
  • Movement joints packed with grit and debris
  • Greasy, split joints in a kitchen or tea point
  • Layers of sealant, all of them failing

Sites a few miles apart, such as Ashwyn Business Centre and Sheddingdean Business Centre, can share one programme and one point of contact.

What your quote should include

  • What the guarantee covers, and for how long
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Health and safety accreditation such as CHAS
  • Proof of insurance
