Construction mastic in Cocking Causeway, done properly

A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place. We work on brick and block movement joints, internal decorators’ caulk and window and door perimeters, and the failures we’re asked to look at most are failed sealant in an existing building being refurbished and mastic snags holding up handover. One point of contact handles commercial sealant work in Cocking Causeway from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Around smaller places like Cocking Causeway, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • Frames fitted out of tolerance
  • Deciding which fire-stopping product a penetration needs
  • Rework caused by others damaging completed areas

Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly.

What we seal

  • Internal decorators’ caulk
  • Window and door perimeters
  • Cladding and panel joints
  • Brick and block movement joints
  • Floor and skirting junctions
  • Sanitary and kitchen joints

Your questions answered

Is Cocking Causeway off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Does your area include sites such as Holmbush Industrial Estate, near Cocking Causeway?

Yes. We cover Cocking Causeway and the area around it, including industrial estates, business parks and retail parks such as Holmbush Industrial Estate. A few photos and the unit address let us price the work.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Do you offer coloured sealant?

That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Do you do fire-rated sealing on new builds?

Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.

What joints do you seal on a new build?

The scope comes from the specification and drawings, but frames, sanitary, kitchens, caulk where specified and snagging are typical.

Our process

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For work around Cocking Causeway, 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. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Explain the parking and delivery arrangements

How the quote is worked out

Before we quote, we look at:

  • How accessible the joints are
  • The product specified
  • Joint width, depth and condition
  • Site requirements such as inductions and permits

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

However big the job, the same details help:

  • Drawings or a marked-up plan, if available
  • The product your specification calls for
  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to call 01277 525 020 or use the quote form.

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Flag uneven or tapered frame gaps early
  • Get the mastic subcontractor involved early in the programme
  • Brief following trades on areas that have been sealed
  • Stick to the specified sealant rather than a generic substitute

Record which products went where in the handover file. That helps the building owner maintain the joints later. Tell us what records you need and we’ll confirm with the quote.

Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short, and avoids a rush.

New build and refits around Cocking Causeway

Central London is about 46 miles from Cocking Causeway. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. A number of hotels sit less than 2 miles from Cocking Causeway. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

For contractors at a school such as Midhurst CofE Primary School, sealing has to be finished before term starts. New units and refits on sites such as Holmbush Industrial Estate, 0.5 miles to the north-west of Cocking Causeway, need their panel and perimeter joints sealed to the specification. With historic properties like Cowdray House, 1.2 miles north of Cocking Causeway, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Why it’s worth doing now in Cocking Causeway

Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. For buildings around smaller places like Cocking Causeway, 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.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
