Your questions answered

Is Farleigh Wallop too small for you to travel to?

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

Could you schedule work at a campus like Queen Mary's College for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Construction mastic in Farleigh Wallop

External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal areas can typically carry on while the outside waits. If you have internal caulk splitting as the building dries out and different trades sealing to different standards, we can put it right. Looking for mastic applicators who cover Farleigh Wallop? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around smaller places like Farleigh Wallop, building work normally 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.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Jobs in and around smaller places like Farleigh Wallop are normally planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  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.

What we need from you

  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work
  • Tell us what induction or permit system the site runs

Ask for a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email the details over.

When it isn’t the sealant

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Frame gaps too wide for sealant, which the installer needs to correct
  • Specifying the product where the designer hasn’t

If you are not sure, just call 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

What we seal

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

Construction mastic in Farleigh Wallop: the local picture

Rainfall across the South East, Farleigh Wallop included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. At about 48 miles from central London, Farleigh Wallop is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

School extensions, at buildings such as Brighton Hill Community School, typically run to the summer holidays, mastic included. With historic properties like Hall Place, 5 miles south-east of Farleigh Wallop, in the area, refurbishment work often meets old masonry that needs compatible sealants. For a contractor working at a hospital such as Basingstoke and North Hampshire Hospital (4.4 miles north of Farleigh Wallop), perimeter and facade sealing is planned around patients and deliveries.

Farleigh Wallop is about 3 miles south of Basingstoke, in Hampshire. Anywhere in RG25, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Hampshire coverage takes in 723 places, large and small. Reading is covered too, some 17 miles away.

Anyone looking for construction mastic in RG25 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

After the work

To get the most from the new sealant:

  • Keep scrapers and abrasive pads off new beads
  • Put any product change through the designer first
  • Don’t force external sealing on a damp or frosty day
  • Brief following trades on areas that have been sealed

Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead so keep them off the joints.

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.

Why it’s worth doing now in Farleigh Wallop

It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification. Called in at the end, the same issues surface during handover. Around Farleigh Wallop, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

What affects the price in Farleigh Wallop

What shapes the price:

  • Backing rod, priming and other preparation
  • The site’s rules and procedures
  • How accessible the joints are
  • How much there is to seal

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • A wide shot and a close-up of the area
