How we handle facade sealing in Eastry

Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. Site teams most often ask us about discoloured or dirty facade joints and cladding panel joints that have opened up, on coping and flashing joints, stone and brick facade joints and perimeter joints where frames meet the structure. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Eastry is the same: the right product in a properly prepared joint.

Conversions around smaller places like Eastry often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to call us in Eastry

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Site and facilities staff are often the first to spot these:

  • Failed sealant on precast panel joints
  • Failed seals around shopfront and entrance frames
  • Old perimeter mastic that has dried out
  • Damp patches beside frames after rain

For contractors at a school such as Eastry Church of England Primary School, sealing has to be finished before term starts.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • Do they follow the manufacturer’s priming guidance?
  • Their plan for phasing and protecting the area
  • Which product they’ll use, and why it suits the joint

Our contractor checklist

Leave it or put it right?

Topping up a failed joint normally buys very little time. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. In a smaller place such as Eastry, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

What you get with us

  • CHAS accredited contractor
  • 12 months’ guarantee on every job
  • RAL and finish matching where the product range allows
  • Fully insured, including public liability cover

Building owners, agents and FMs in Eastry

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Cracked or spalling substrates that need repair before sealing
  • Joints too narrow for the movement they take, which need redesign
  • Providing access systems for the work

If you are not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer.

Where we work in Eastry

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

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. For a job in Eastry, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.

  1. We look at the joints, the drawings and the access before pricing.
  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.

Getting the site ready

  • Send any specification or drawings in advance
  • Agree which areas must stay open
  • For older buildings, check the asbestos register before work

Mastic packages on Eastry sites

Eastry lies roughly 63 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme. Eastry sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

Units on estates such as Birnham Farm Business Centre (1.2 miles north-west of Eastry) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Older buildings in the area around Eastry, such as Goodnestone Park, 3.4 miles west of Eastry, need care when sealed: the product has to suit soft or historic materials.

Eastry is about 4 miles north-west of Deal, in Kent. We send applicators to Eastry for facade joints. Our Kent coverage takes in 931 places, from busy centres to rural villages. Our London page has more on work in that area (63 miles or so).

Streets here include High Street, Swaynes Way and Wheelwrights Way, and sites on any of them can send details for a fixed quote.

Your questions answered

Is a smaller place like Eastry outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is Birnham Farm Business Centre, near Eastry, within your area?

Yes, sites like Birnham Farm Business Centre are within our area, along with the rest of Eastry. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you take on multi-site work?

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

Do you seal facades in winter?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start, and we build that into the programme.

How do I request a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
