Facade sealing across Throwley

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Facade sealing in Throwley, done properly

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we’ll fit the work around it. We work on stone and brick facade joints, cladding panel joints and window and door perimeters, and what we are called in for most is perimeter joints where frames meet the structure and leaks at window and door perimeters. One point of contact handles commercial sealant work in Throwley from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Conversions of older rural buildings near smaller places such as Throwley 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 normally what’s needed.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Throwley can form part of a wider programme.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Throwley, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  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. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Let us know about inductions and permits
  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Related advice

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Keep sills, gutters and drainage paths clear
  • Avoid patch repairs on failed facade joints
  • Don’t wait for a second leak before calling
  • Ask about asbestos in pre-2000 mastic

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos.

Your questions answered

Is Throwley too far out for you?

No. Places such as Throwley are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

What paperwork can you provide for a job in Throwley?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is colour matching possible?

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

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Will rain stop the work?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Do you replace windows or glass?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.

Common problems we fix in Throwley

When the sealant tears down its centre, it has usually been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Any of the following is a good reason to get the joints checked over:

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

Historic houses such as Belmont House and Gardens (0.6 miles north-west of Throwley) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

What your quote should include

  • Whether primer will be used where the manufacturer specifies it
  • Proof of insurance
  • How they’ll work around occupants
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Mastic packages on Throwley sites

Rainfall across the South East, Throwley included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Throwley is about 44 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.

Sites around Throwley get mastic sealed to the drawings and the programme, nothing improvised.

Throwley is about 4 miles south of Faversham, in Kent. Our applicators travel to Throwley for work on facade joints. Throwley is one of 931 places in Kent on our list for facade joints. London is covered too, around 44 miles from Throwley.

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What sets the cost

To price the job, we consider:

  • The total length or number of joints
  • Whether old sealant has to be cut out first
  • Which sealant the job calls for
  • Whether the work must be split into stages

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • Specification clauses that apply
  • Where the site is, with the postcode
  • Clear photos of the problem areas
  • Asbestos survey details if the building is older

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or email us.
