Facade sealing for businesses in Eastwood

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing in Eastwood

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. We work on perimeter joints where frames meet the structure, shopfront frames and coping and flashing joints, and the failures we are asked to look at most are perimeter joints where frames meet the structure and damp patches beside frames after rain. For commercial sealant work in Eastwood, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Conversions of older rural buildings near smaller places such as Eastwood bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How a job runs

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in and around smaller places like Eastwood are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  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. We walk the finished joints with you before handing over.

Preparing the site

  • Move anything stored against the joints
  • Send any specification or drawings in advance
  • Let us know about inductions and permits

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Investigate damp beside windows promptly
  • Combine resealing with other works that need access
  • Add perimeter sealant to planned maintenance checks
  • Record the product and colour used on each elevation

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly using a matching sealant.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down and limits disruption.

Signs you need facade sealing in Eastwood

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

Typical triggers for a call:

  • Weathered facade joints that have lost their grip
  • Staining on stone next to old sealant
  • Leaks at window and door perimeters
  • Failed seals around shopfront and entrance frames

For contractors on a campus like Canterbury Christ Church University, which lies north of Eastwood, facade and perimeter sealing has to fit around students and term dates.

What your quote should include

  • Who will actually carry out the work
  • Their plan for phasing and protecting the area
  • Do they follow the manufacturer’s priming guidance?
  • How joint depth will be controlled

Choosing a commercial sealant contractor

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

New build and refits around Eastwood

Eastwood is about 38 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Eastwood sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

For contractors refurbishing units at places like Roebuck Business Park, 2.6 miles north of Eastwood, the mastic covers cladding panels, roller-door and window perimeters. Older buildings in the area around Eastwood, such as Leeds Castle, 3.4 miles to the north-west of Eastwood, need care when sealed: the product has to suit soft or historic materials.

Eastwood is about 7 miles south-east of Maidstone, in Kent. If you are looking for facade sealing in Eastwood, we can help, as we do across Kent. Across Kent, 931 places are covered, including Eastwood. Our London page has more on work in that area.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Providing access systems for the work
  • Joints whose design needs changing by the specifier

If you’re not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer.

Surfaces we seal

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

Common questions from Eastwood clients

Could you schedule work at a campus like Canterbury Christ Church University for the vacation?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you cover business parks and estates near Eastwood, such as Roebuck Business Park?

Yes. Estates, retail parks and business parks around Eastwood, Roebuck Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

Do you offer coloured sealant?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed. Removal of asbestos isn’t something we do.

Can you work to our specification?

Yes. Send it with your enquiry, and we’ll price the work to it.

Are you fully insured?
