Construction mastic in Cattawade

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Construction mastic in Cattawade

Mastic tends to be one of the final packages before handover. We work as a mastic subcontractor to main contractors and developers with projects in Cattawade, sealing plot by plot or floor by floor as areas are released. We work on brick and block movement joints, internal decorators’ caulk and window and door perimeters, and what we are called in for most is a long mastic snag list close to completion and cracks opening in caulked internal joints. Facilities teams, main contractors and managing agents in Cattawade tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Construction in and around smaller places such as Cattawade is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Joint design decisions that belong to the architect or engineer
  • Rework caused by others damaging completed areas

If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Surfaces we seal

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

What happens if it’s left?

Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. Around Cattawade, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why us?

  • One phone line for London, the South East and Scotland
  • Colour options checked against the specified product
  • Products installed to the manufacturer’s instructions
  • Health and safety: CHAS accredited

When to call us in Cattawade

Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.

Look out for the following:

  • Bath and shower joints scraped during the final clean
  • A long mastic snag list close to completion
  • Cracks opening in caulked internal joints
  • Missed perimeter joints on a new elevation

With historic properties like Castle House (to the west of Cattawade) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • Is the sealant right for the movement and the substrate?
  • Their pre-qualification and accreditations
  • Their public liability cover

How to choose a sealant contractor

Keeping the joints sound

For the best life from the joints:

  • Keep scrapers and abrasive pads off new beads
  • Release areas for mastic once other trades have finished in them
  • Brief following trades on areas that have been sealed
  • Ask for joint and product checks before the package is urgent

A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.

Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out.

Questions we are asked in Cattawade

Is Cattawade too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can being near the sea in Cattawade affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Do you offer coloured sealant?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

What if there’s asbestos in the old mastic?

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 if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Do you install fire-rated sealant as part of a package?

Fire-rated sealing at service penetrations and linear gaps can be included where specified. Tell us what records you need and we’ll confirm with the quote.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Smaller jobs around Cattawade can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. Final snagging is completed and the 12-month guarantee applies.

Sites and facades in and around Cattawade

With the shore within about 1 mile, Cattawade counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. A 2-mile radius around Cattawade takes in several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

When a school such as Brooklands Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. New units and refits on sites such as Brantham Mill Industrial Estate (to the west of Cattawade) need their panel and perimeter joints sealed to the specification.
