How we handle construction mastic in Abbots Worthy

On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. If you have existing joints on a refurb that need cutting out and resealing and caulk cracking where joints are moving more than expected, we can help, on sanitary and kitchen joints, brick and block movement joints and internal decorators’ caulk alike. Whoever orders the work in Abbots Worthy, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Abbots Worthy, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

New build and refits around Abbots Worthy

Abbots Worthy sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 59 miles from Abbots Worthy. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

Projects at schools like Kings Worthy Primary School work to term dates, so mastic is programmed tightly. On a campus such as University of Winchester (2.7 miles south-west of Abbots Worthy), new teaching buildings and residences are normally built and refurbished around the academic year.

How the quote is worked out

These are the things that shape the price:

  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants
  • Any access equipment needed
  • Travel to remote or island sites

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

However big the job, the same details help:

  • Any specification or named product
  • Your programme or deadline
  • A wide shot and a close-up of the area
  • Access details, including height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Different surfaces, different methods

Fire-rated sealant where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control; we work to the specification and the manufacturer’s installation guidance.

External facade and movement joints

Many facade substrates need a primer before sealing. We prime where the manufacturer specifies and work only when conditions suit.

What we’re called out for in Abbots Worthy

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.

Typical triggers for a call:

  • Frame perimeters left unsealed or poorly sealed
  • Internal caulk splitting as the building dries out
  • Different trades sealing to different standards
  • Failed sealant in an existing building being refurbished

Further education sites such as Peter Symonds College (2.1 miles south-west of Abbots Worthy) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Our contractor checklist

When to bring in a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Common questions from Abbots Worthy clients

Will you plan work around the academic year at somewhere like University of Winchester?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Abbots Worthy off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you fit around our programme?

We work to your programme. Share the release dates and we will match our work to them, sealing as areas become ready.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Do you use the sealant named in the specification?

We work to the specification and the manufacturer’s installation guidance. Primers, backing and joint depth follow what the manufacturer sets out.

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Ask installers to correct oversized gaps first
  • Ask cleaners to use soft cloths around fresh sealant
  • Protect sealed areas from following trades
  • Allow flexibility for external sealing in damp or cold weather

Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead.

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 keeps handover on track.
