Signs you need facade sealing in Chambers' Green

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead.

These are often picked up first by site or facilities staff:

  • Staining on stone next to old sealant
  • Sealant pulling away from frames or panels
  • Failed sealant on precast panel joints
  • Air leaks through failed facade joints

With historic properties like Godinton House, 3.7 miles east of Chambers' Green, in the area, refurbishment work often meets old masonry that needs compatible sealants.

How we handle facade sealing in Chambers' Green

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. If you are dealing with air leaks through failed facade joints and staining on stone next to old sealant, we can put it right. Most enquiries from Chambers' Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In the countryside around places like Chambers' Green, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What happens if it’s left?

Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Halls, stores and units around places like Chambers' Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What you get with us

  • Matching to RAL references, product permitting
  • Public liability insurance in place
  • Standard and matched colours in many product ranges
  • 12-month guarantee on workmanship

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites around Chambers' Green. Several sites can go on one quote, which keeps the paperwork simple.

On site: what to expect

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. For work around Chambers' Green, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  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. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Tell us which areas need to stay in use
  • Send your site hours and access windows

New build and refits around Chambers' Green

At about 43 miles from central London, Chambers' Green is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Chambers' Green is in the South East, one of the UK’s drier regions. 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.

School extensions, at buildings such as Pluckley Church of England Primary School, typically run to the summer holidays, mastic included.

Chambers' Green is about 5 miles west of Ashford, in Kent. Commercial clients in Chambers' Green can call on us for facade joints, as part of our coverage of Kent. Our Kent coverage takes in 931 places. Sites around London have their own page, roughly 43 miles from Chambers' Green.

How the quote is worked out

What shapes the price:

  • Distance, for remote addresses
  • Induction, permit and paperwork requirements
  • Removal of failed or old sealant
  • The total length or number of joints

A quote for facade joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

What to include in your enquiry

Good information means a firmer quote. When you get in touch, include:

  • The postcode of the building
  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or send details through our quote form.

What we can’t put right

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

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Installing or repairing glazing systems
  • Joints too narrow for the movement they take, which need redesign

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Surfaces we seal

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

Common questions from Chambers' Green clients

Is Chambers' Green too far out for you?

Not at all. Chambers' Green is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Can you keep pace with our programme in Chambers' Green?

Yes. The mastic is planned around your key stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.

Can you find out why a window is leaking?

Yes. We look at the perimeter sealant and tell you whether it has failed. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.
