Commercial sealant contractors for commercial buildings in Cocking Causeway

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). If you are dealing with water staining near frames, panels or ceilings and frame mastic that has hardened and come away from the wall, we can put it right, on washrooms and tea points, floor and threshold joints and movement joints in walls and floors alike. Looking for mastic applicators who cover Cocking Causeway? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

In Cocking Causeway, as anywhere, the first joints to go are typically the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.

Commercial sealant work around smaller places like Cocking Causeway tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

A 12-month guarantee applies to all our work in West Sussex. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we will arrange a return visit.

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Cocking Causeway need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
  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. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Before we start on site

  • Point out parking and an unloading spot
  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work

What we can’t put right

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

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Water from a services leak rather than a joint

If in doubt, ring 01277 525 020 or send photos by email and we will say what we think before you book.

Joints and surfaces we work on

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

When to call us in Cocking Causeway

Outside, sunlight and rain wear sealant down year after year. Sunny elevations dry the surface out and exposed ones take driving rain. A hardened bead can’t follow the building any more.

Look out for the following:

  • Window and door perimeter joints that have cracked open
  • Leaks that seem to come through a sealant line
  • Earlier reseals applied straight onto the failed bead
  • Movement joints packed with grit and debris

In hotels such as The Spread Eagle Hotel, 1 mile to the north of Cocking Causeway, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

What your quote should include

  • Proof of insurance
  • Whether primer will be used where the manufacturer specifies it
  • The named product and why it was chosen
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Access and working height
  • Which sealant the job calls for
  • Site requirements such as inductions and permits
  • Removal of failed or old sealant

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • The type of building and who uses it
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours
  • Any dates the work must fit around

To get a fixed quote, give us a call on 01277 525 020 or email drawings and photos. Our quote form is another easy route.

Leave it or put it right?

It can be tempting to hold sealant work back until the next refurbishment. That’s reasonable for internal joints that are just tired-looking, but a joint letting water in now keeps doing damage until the refurb arrives. Splitting the scope into now and later is often the sensible compromise. Older rural buildings around Cocking Causeway 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.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

What you get with us

  • Old sealant cut out, never sealed over
  • CSCS-carded applicators
  • Colours confirmed for the specified product
  • Sealing commercial buildings since 2005

Common questions from Cocking Causeway clients

Must a hotel around Cocking Causeway close while you work?

Do you cover business parks and estates near Cocking Causeway, such as Holmbush Industrial Estate?

Yes. We cover Cocking Causeway and the area around it, including industrial estates, business parks and retail parks such as Holmbush Industrial Estate. Photos and a short description are enough for a first look.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Can you handle sealant work across several sites?

Yes, we can. Give us the sites and the scope at each, and fixed prices follow, with a suggested sequence.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you work directly for building managers?

Yes. FMs, managing agents and landlords are among our regular clients. We can work to your instruction process and site rules.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
