Why it’s worth doing now in Boxgrove

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Around Boxgrove, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why us?

  • Constructionline member for supplier checks
  • Fully insured, including public liability cover
  • 12 months’ guarantee on every job
  • Failed material removed, not covered up

Facade sealing for commercial buildings in Boxgrove

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. We work on window and door perimeters, stone and brick facade joints and cladding panel joints, and the failures we are asked to look at most are failed sealant on precast panel joints and weathered facade joints that have lost their grip. Looking for mastic applicators who cover Boxgrove? We have been sealing commercial buildings since 2005.

In the countryside around places like Boxgrove, 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 typically what’s needed.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we will come back to it.

Boxgrove: questions and answers

Would you work within a site like St Richard's Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

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

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

How do we ask for a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we’ll price the work to it.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Is old mastic on our building likely to contain asbestos?

For older buildings, yes, check before work starts. The dutyholder holds the asbestos register. If asbestos is suspected, work stops until it is tested.

Contractors’ notes for Boxgrove

At about 52 miles from central London, Boxgrove is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. There are a number of hotels within about 2 miles of Boxgrove. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.

Building work at universities like University of Chichester (to the west of Boxgrove) is often timed for the summer, mastic included. Projects at schools like Boxgrove CofE Primary School work to term dates, so mastic is programmed tightly.

What the job involves on each surface

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Boxgrove are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Honest limits

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Replacing glass or failed glazing units
  • Render or concrete edges that have broken away
  • Joints too narrow for the movement they take, which need redesign

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

Joints and surfaces we work on

  • Perimeter joints where frames meet the structure
  • Shopfront frames
  • Coping and flashing joints
  • Cladding panel joints
  • Stone and brick facade joints
  • Window and door perimeters

Do you need facade sealing in Boxgrove?

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.

Common reasons buildings call us in:

  • Failed seals around shopfront and entrance frames
  • Patch repairs that keep failing
  • Discoloured or dirty facade joints
  • Draughts around frames and panels

Work at a hotel such as The Richmond Arms Hotel (to the north-west of Boxgrove) tends to be programmed around bookings, mastic included.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • Health and safety accreditation such as CHAS
  • Whether primer will be used where the manufacturer specifies it
  • Can the work be phased to keep areas open?
