How we handle facade sealing in Ashford

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. If you are dealing with failed seals around shopfront and entrance frames and previous reseals run over old sealant, we can help. Searching for sealant specialists in Ashford? We have been sealing commercial buildings since 2005.

In the countryside around places like Ashford, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Different surfaces, different methods

Window and door perimeters

Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus neutral-cure product, chosen for the frame and wall, goes in, tooled to shed water.

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.

Facade sealing around Ashford: points for this area

The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

For contractors at a school such as Fordingbridge Junior School, sealing has to be finished before term starts. On a healthcare site such as Fordingbridge Hospital (0.6 miles east of Ashford), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

When to call us in Ashford

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

What tends to prompt an enquiry:

  • Facade joints cracked through the middle
  • Damp patches beside frames after rain
  • Draughts around frames and panels
  • Unsightly perimeter sealant on a visible elevation

Historic houses such as Breamore House (3 miles north of Ashford) 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

  • Their approach to joint depth and backing
  • What the guarantee covers, and for how long
  • Will CSCS-carded applicators be on site?
  • Can the work be phased to keep areas open?

Our contractor checklist

Questions we are asked in Ashford

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

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Ashford off your patch?

No. Places such as Ashford are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can the building stay open while you work?

In the majority of cases, yes. We phase the work so most of the building stays in use.

Can the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Do you use silicone for external joints?

The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

When something else is needed

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Joints whose design needs changing by the specifier
  • Cracked or spalling substrates that need repair before sealing
  • Damp caused by condensation inside the building

Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly.

Where we work in Ashford

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

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. If others near Ashford need work, visits can be combined. A fixed quote is given before anything starts.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for 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.

What we need from you

  • Send any specification or drawings in advance
  • Explain the parking and delivery arrangements
  • Share the asbestos register for older buildings

Cost factors for facade joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Which sealant the job calls for
  • How much existing material needs removing
  • Any access equipment needed
  • Induction, permit and paperwork requirements

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • The product your specification calls for
  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings

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, give us a call on 01277 525 020 or email a schedule or drawings.
