How we handle facade sealing in West Hill

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. We work on window and door perimeters, cladding panel joints and shopfront frames, and the failures we are asked to look at most are perimeter joints where frames meet the structure and old perimeter mastic that has dried out. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in West Hill is the same: the right product in a properly prepared joint.

Around places like West Hill, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Commercial clients in West Hill

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Site staff or a sealant specialist?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Surface by surface

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair before sealing.

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and we clear our waste as we work. For a job in West Hill, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  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.

Before we start on site

  • Let building users know which areas are affected
  • Point out parking and an unloading spot
  • Make sure the joints can be reached

Advice

Mastic packages on West Hill sites

West Hill sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Rainfall across the South East, West Hill 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, which is why external dates are agreed with the site manager.

Further education sites such as Waterbear College Brighton, under half a mile south-east of West Hill, are extended and refurbished from time to time, with mastic often programmed into the summer break. Units on estates such as Centenary Industrial Estate (to the north-east of West Hill) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

West Hill is about 1 mile west of Brighton, in Brighton and Hove. Businesses, contractors and managing agents in West Hill can call on us for facade joints, as part of our coverage of Brighton and Hove. Across Brighton and Hove, 29 places are covered, West Hill among them.

West Hill: questions and answers

Is West Hill off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work around term dates at a campus such as University of Brighton Moulesecoomb Campus?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day.

Can one quote cover more than one building?

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

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Common problems we fix in West Hill

Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone.

If one of these sounds familiar, it’s time for a closer look:

  • Old perimeter mastic that has dried out
  • Failed seals around shopfront and entrance frames
  • Cold air coming in at window perimeters
  • Patch repairs that keep failing

Work at a hotel such as Britannia Study Hotel, under half a mile to the south-west of West Hill, tends to be programmed around bookings, mastic included.

What to look for in a quote

  • How long is the guarantee, and what does it include?
  • Health and safety accreditation such as CHAS
  • What site paperwork they can supply
  • Is the sealant right for the movement and the substrate?

Our contractor checklist

Why deal with it now?

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 early costs far less than repairing what the water reaches. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
