Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Damp caused by condensation inside the building
  • Damaged frames that need replacing
  • Work on the window or framing system itself

Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Where we work in South Stour

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

Facade sealing for commercial buildings in South Stour

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters. Most enquiries involve cladding panel joints that have opened up and patch repairs that keep failing, across cladding panel joints, perimeter joints where frames meet the structure and window and door perimeters. Facilities teams, main contractors and managing agents in South Stour tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Sites around smaller places like South Stour 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’ll quote to suit.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • How accessible the joints are
  • The total length or number of joints
  • Backing rod, priming and other preparation
  • How much existing material needs removing

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Details that help us quote

A few photos plus some basic facts will normally do. It helps to include:

  • The product your specification calls for
  • The postcode of the building
  • Any dates the work must fit around
  • Asbestos survey details if the building is older

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send photos by email.

Signs you need facade sealing in South Stour

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.

Look out for the following:

  • Old perimeter mastic that has dried out
  • Staining on stone next to old sealant
  • New sealant peeling off old mastic
  • Perimeter sealant that has split or peeled away

School extensions, at buildings such as Finberry Primary School, typically run to the summer holidays, mastic included.

How to choose a sealant contractor

What happens if it’s left?

Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. Older rural buildings around South Stour move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • Clear, fixed quotes
  • Failed material removed, not covered up
  • Our applicators hold CSCS cards
  • A Constructionline member, so easy to vet

When to bring in a specialist

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.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. Rural sites near South Stour may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  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.

Preparing the site

  • Warn occupants and staff about the work
  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification

South Stour: questions and answers

Is a smaller place like South Stour outside your area?

No. Places such as South Stour are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you work around term dates at a campus such as Ashford College?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Can you work in cold or wet weather?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Building and refurbishing in South Stour

South Stour lies roughly 51 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. The South East is one of the drier 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.

On a healthcare site such as William Harvey Hospital (Ashford), which lies north of South Stour, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Units on estates such as Bliby Business Centre (to the south-west of South Stour) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

South Stour is about 3 miles south-east of Ashford, in Kent. Looking for facade sealing in South Stour? We can help, as we do across Kent. South Stour is one of 931 places we cover in Kent for facade joints. Sites around Brighton have their own page, roughly 49 miles from South Stour.
