Facade sealing for businesses in Hurstpierpoint

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Cost factors for facade joints

The price varies from site to site. It mainly depends on:

  • Quantities, in metres or numbers
  • Joint width, depth and condition
  • Removal of failed or old sealant
  • Which sealant the job calls for

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What we need to price the job

However big the job, these details speed things up:

  • Whether an asbestos survey exists
  • Where the site is, with the postcode
  • Specification clauses that apply
  • When you need the work done

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or use the quote form.

Facade sealing in Hurstpierpoint

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on perimeter joints where frames meet the structure, stone and brick facade joints and window and door perimeters, and what we are called in for most is hard, chalky sealant that no longer flexes and sealant pulling away from frames or panels. A single leaking joint is often how a building in Hurstpierpoint first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a contractor on a smaller site near Hurstpierpoint, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.

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.

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. Work in places the size of Hurstpierpoint is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Agree which areas must stay open
  • Move anything stored against the joints

Building owners, agents and FMs in Hurstpierpoint

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Your questions answered

Does your area include sites such as Kings Business Centre, near Hurstpierpoint?

Yes. We cover Hurstpierpoint and the area around it, including industrial estates, business parks and retail parks such as Kings Business Centre. Send details of the unit and the work through our quote form for a quick quote.

Is a hospital such as The Dene Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you install glazing systems?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters across the facade.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Can you handle several sites?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

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

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Why deal with it now?

If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice. For buildings in places like Hurstpierpoint, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Cracked or spalling substrates that need repair before sealing
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints too narrow for the movement they take, which need redesign

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

Joints and surfaces we work on

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

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Confirm the survey covers external sealants in older buildings
  • Avoid patch repairs on failed facade joints
  • Inspect facade joints on a regular cycle
  • Don’t wait for a second leak before calling

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.

Sites and facades in and around Hurstpierpoint

Hurstpierpoint lies roughly 39 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Hurstpierpoint 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 the external programme keeps a little slack.

Projects at schools like St Lawrence CofE Primary School work to term dates, so mastic is programmed tightly. On a healthcare site such as The Dene Hospital, which lies north of Hurstpierpoint, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors refurbishing units at places like Kings Business Centre, which lies north-west of Hurstpierpoint, the mastic covers cladding panels, roller-door and window perimeters.
