Construction mastic in Bashley

Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Bashley, send drawings and the specification through our quote form. We work on sanitary and kitchen joints, window and door perimeters and cladding and panel joints, and what we are called in for most is snag items on joints that need redoing before handover and a mastic package split between trades with no clear owner. A specialist sealant contractor works differently from a general builder: in Bashley, that means joint design, primers and backing rod as standard.

In the countryside around places like Bashley, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we are called out for in Bashley

Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.

Clients normally get in touch after noticing one or more of the following:

  • Existing joints on a refurb that need cutting out and resealing
  • Cracks opening in caulked internal joints
  • New external sealant already peeling away
  • Frame perimeters left unsealed or poorly sealed

School extensions, at buildings such as Ballard School, normally run to the summer holidays, mastic included.

What to look for in a quote

  • The terms of the workmanship guarantee
  • What site paperwork they can supply
  • Can the work be phased to keep areas open?
  • Whether old or failed sealant will be cut out, not overlaid

Choosing a commercial sealant contractor

Cost factors for mastic packages

Your fixed quote is built from the real scope. It allows for:

  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Any access equipment needed
  • Phasing around occupants

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Where the site is, with the postcode
  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email a schedule or drawings.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Rework caused by others damaging completed areas
  • Glazing units that are cracked or misted
  • Deciding which fire-stopping product a penetration needs

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think before you book.

Joints and surfaces we work on

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

Questions about Bashley

Is a smaller place like Bashley outside your area?

Not at all. Bashley is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is a hospital such as Lymington New Forest Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.

Can you come in just for snagging?

Yes, we can. Send the snag list or photographs and we’ll price it.

Do you guarantee new-build sealant work?

Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we have finished isn’t covered.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Construction mastic in Bashley: the local picture

Bashley sits close to the coast, within about 3 miles. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Bashley included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.

When units on a site such as Gore Road Industrial Estate, 1.6 miles south of Bashley, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hospital estates such as Lymington New Forest Hospital (to the east of Bashley) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Snagging before handover

Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit, depending on what suits the programme.

Kitchens and utility areas

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used, food-safe where food contact is possible.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Keep scrapers and abrasive pads off new beads
  • Ask for joint and product checks before the package is urgent
  • Stick to the specified sealant rather than a generic substitute
  • Allow flexibility for external sealing in damp or cold weather

After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby.

One unsealed frame can let water into finished internal areas. That typically means redoing finishes in a completed area. Checking perimeters before internal finishes go on avoids it.
