FAQs: Rusper

Will you take on work at estates like Holmbush Potteries Industrial Estate, close to Rusper?

Yes. Our area takes in Rusper and its surroundings, with estates and business parks such as Holmbush Potteries Industrial Estate included. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is Rusper too small for you to travel to?

No. Places such as Rusper are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Which sealant do you use on facades?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Facade sealing for commercial buildings in Rusper

We don’t install glazing systems or replace glass. 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 shopfront frames, cladding panel joints and stone and brick facade joints, and what we are called in for most is sealant pulling away from frames or panels and failed sealant on precast panel joints. Whoever orders the work in Rusper, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

In the countryside around places like Rusper, 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.

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.

When to call us in Rusper

Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

These are often picked up first by site or facilities staff:

  • Hard, chalky sealant that no longer flexes
  • Discoloured or dirty facade joints
  • Sealant pulling away from frames or panels
  • Gaps between rainscreen or cladding panels

For contractors at a school such as Rusper Primary School, sealing has to be finished before term starts.

What to look for in a quote

  • Whether old or failed sealant will be cut out, not overlaid
  • Their pre-qualification and accreditations
  • What site paperwork they can supply
  • Their approach to joint depth and backing

Choosing a commercial sealant contractor

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Specialist high-level access methods
  • Damp caused by condensation inside the building
  • Damaged frames that need replacing

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

Where we work in Rusper

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

When to bring in a specialist

Some joints are best left to specialists: for instance 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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Building and refurbishing in Rusper

Rusper is about 27 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. 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.

For a contractor working at a hospital such as Crawley Hospital (3.6 miles east of Rusper), perimeter and facade sealing is planned around patients and deliveries. Units on estates such as Holmbush Potteries Industrial Estate, 2.4 miles to the south-east of Rusper, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Rusper is about 4 miles west of Crawley, in West Sussex. Commercial clients in Rusper can call on us for facade joints, as part of our coverage of West Sussex.

Maintenance after handover

For the best life from the joints:

  • Never let anyone seal over old sealant
  • Add perimeter sealant to planned maintenance checks
  • Combine resealing with other works that need access
  • Check the asbestos register before old mastic is disturbed

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.

Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.

From enquiry to sign-off

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 move on in phases so staff and visitors can carry on around us. For work around Rusper, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Explain the parking and delivery arrangements
  • Send your site hours and access windows
  • Have the specification and drawings to hand
