Facade sealing in Hellingly

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Confirm the survey covers external sealants in older buildings
  • Note when each elevation was last resealed
  • Report water ingress at frames as soon as it shows
  • Avoid harsh cleaners on facade sealant

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal across the elevation.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Facade sealing for commercial buildings in Hellingly

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. We work on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure, and the failures we’re asked to look at most are unsightly perimeter sealant on a visible elevation and old perimeter mastic that has dried out. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hellingly is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around places like Hellingly, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Cost factors for facade joints

Your fixed quote is built from the real scope. It takes account of:

  • Location, for remote and island sites
  • How much there is to seal
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

  • Whether the building will be occupied during the work
  • Your programme or deadline
  • A wide shot and a close-up of the area
  • Access details, including height

To get a fixed quote, ring 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. You can also send details through our quote form.

Doing it in-house

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.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

When to call us in Hellingly

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building, then it splits or peels.

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

  • Failed seals around shopfront and entrance frames
  • Facade joints cracked through the middle
  • Unsightly perimeter sealant on a visible elevation
  • Old perimeter mastic that has dried out

For a contractor working at a hospital such as Amberstone Hospital, which lies east of Hellingly, perimeter and facade sealing is planned around patients and deliveries.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Diagnose, treat, sign off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a job in Hellingly, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Let building users know which areas are affected
  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Advice

Common questions from Hellingly clients

Is Hellingly too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Do you take on work at healthcare sites like Amberstone 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.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Is colour matching possible?

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 confirm what’s available for the specified product when we quote.

Is your workmanship covered by a guarantee?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

New build and refits around Hellingly

Hellingly sits in one of the drier corners of the country, the South East. 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. The area within 2 miles of Hellingly holds a number of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

Projects at schools like Hawkes Farm Academy work to term dates, so mastic is programmed tightly. Units on estates such as Crown Close Industrial Estate, 1.6 miles south of Hellingly, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Hellingly is about 1 mile north of Hailsham, in East Sussex. We cover Hellingly and the rest of East Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.
