About our facade sealing in Chinbrook

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 cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on window and door perimeters, stone and brick facade joints and cladding panel joints, and the usual reasons a site gets in touch are old perimeter mastic that has dried out and patch repairs that keep failing. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Chinbrook it comes down to the same thing: the right product in a properly prepared joint.

Every London site, Chinbrook included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites normally need booked deliveries and a plan for where materials go.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Quoting for work in Chinbrook

Each job is priced on its own details. The main factors are:

  • How much existing material needs removing
  • Site requirements such as inductions and permits
  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • Any dates the work must fit around
  • Whether an asbestos survey exists
  • The site address and postcode
  • Anything awkward about access or site hours

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email the details over.

Why act early in Chinbrook

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, saving a second set-up. Failed sealant in a building in Chinbrook can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Why us?

  • Clear, fixed quotes
  • One contact handling all your sites
  • Public liability insurance in place
  • Coloured sealants to suit the setting, where available

FAQs: Chinbrook

Can you take on a job at a hospital such as Eltham Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Green Lane Business Park, near Chinbrook, within your area?

Yes. We cover Chinbrook and the area around it, including industrial estates, business parks and retail parks such as Green Lane Business Park. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

How much does the work cost?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or use the quote form.

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.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Do you use silicone for external joints?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.

How long before the joints can be used?

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

On site: what to expect

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. In Chinbrook, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

What we need from you

  • Warn occupants and staff about the work
  • Flag any permit to work we’ll need
  • Send any specification or drawings in advance

When to call us in Chinbrook

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

If one of these sounds familiar, it’s time for a closer look:

  • Damp patches beside frames after rain
  • New sealant peeling off old mastic
  • Staining on stone next to old sealant
  • Old perimeter mastic that has dried out

For contractors at a college like Hadlow College (0.6 miles north of Chinbrook), perimeters and internal sealant are timed for the holidays.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • How the joint faces will be prepared and primed
  • How long is the guarantee, and what does it include?
  • How joint depth will be controlled

Facade sealing around Chinbrook: what changes locally

Site traffic in Chinbrook falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are several hotels within about 2 miles of Chinbrook. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.

Hotel extensions and refits, at places such as Baring Hall Hotel, 0.5 miles west of Chinbrook, normally run between busy periods, so the sealing is squeezed into short windows. On a campus such as University of Greenwich - Avery Hill, which lies north-east of Chinbrook, new teaching buildings and residences are typically built and refurbished around the academic year.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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

What the job involves on each surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.

Cladding panel joints

On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them to the correct depth.
