General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

About our facade sealing in Chillenden

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on commercial buildings in Chillenden. Where sealant is the specified fix, we also take on coping and flashing joints. If you have draughts around frames and panels and gaps between rainscreen or cladding panels, we can put it right, whatever the surface. Whoever orders the work in Chillenden, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Sites around smaller places like Chillenden can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Arranging specialist high-level access, which is planned with the client
  • Installing or repairing glazing systems
  • Cracked or spalling substrates that need repair before sealing

If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Joints and surfaces we work on

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

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Chillenden, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  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. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  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

  • Point out any areas we must not close
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

FAQs: Chillenden

Is Chillenden too small for you to travel to?

Not at all. Chillenden is within our area. 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.

Do you cover business parks and estates near Chillenden, such as Pike Road Industrial Estate?

Yes. Our area takes in Chillenden and its surroundings, with estates and business parks such as Pike Road Industrial Estate included. Photos and a short description are enough for a first look.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months on every job.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Do you need facade sealing in Chillenden?

Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.

Look out for the following:

  • New sealant peeling off old mastic
  • Leaks at window and door perimeters
  • Cladding panel joints that have opened up
  • Sealant pulling away from frames or panels

When a school such as Goodnestone Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

  • Will RAMS and insurance details be available?
  • Their public liability cover
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

Facade sealing in Chillenden: the local picture

Rainfall across the South East, Chillenden included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Chillenden is about 61 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

Historic houses such as Goodnestone Park, 1.2 miles to the north-west of Chillenden, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. For contractors refurbishing units at places like Pike Road Industrial Estate, 2.3 miles to the south-east of Chillenden, the mastic covers cladding panels, roller-door and window perimeters.

Why deal with it now?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Halls, stores and units around places like Chillenden may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Pricing facade joints depends on quantities, condition and access. Call for a quote.
