Facade sealing near Conyer

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What happens if it’s left?

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once, saving a second set-up. Older rural buildings around Conyer move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

About our facade sealing in Conyer

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Site teams most often ask us about unsightly perimeter sealant on a visible elevation and facade joints cracked through the middle, across stone and brick facade joints, shopfront frames and window and door perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, in Conyer it comes down to the same thing: the right product in a properly prepared joint.

Around smaller places like Conyer, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

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.

What we can’t put right

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Movement beyond what any sealant can handle
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Damaged frames that need replacing

Not sure which it is? You can phone 01277 525 020 or send photos by email and we will tell you honestly before you book.

Joints and surfaces we work on

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

Questions about Conyer

Does the sea air around Conyer change the choice of sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is a smaller place like Conyer outside your area?

No. Small places get the same service as large ones. 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.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you replace windows or glass?

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

Is it okay to overlay old mastic?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Conyer, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Photos, drawings or a visit tell us about the joints and the 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 is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work

Advice

Common problems we fix in Conyer

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.

Look out for the following:

  • Gaps between rainscreen or cladding panels
  • Patch repairs that keep failing
  • Draughts around frames and panels
  • Hard, chalky sealant that no longer flexes

For contractors building in or near Conyer, we seal to the drawings, the specification and the programme.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • The named product and why it was chosen
  • Proof of insurance
  • The terms of the workmanship guarantee

How to choose a sealant contractor

Should maintenance staff do it?

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. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Building owners, agents and FMs in Conyer

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Conyer can form part of a wider programme.

Building and refurbishing in Conyer

Conyer lies within about 1 mile of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Conyer lies roughly 41 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.

For contractors at a college like KITE College (3 miles west of Conyer), perimeters and internal sealant are timed for the holidays.
