Facade sealing in Yelsted

We don’t install glazing systems or replace glass. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. We work on window and door perimeters, cladding panel joints and shopfront frames, and the failures we are asked to look at most are leaks at window and door perimeters and new sealant peeling off old mastic. Searching for sealant specialists in Yelsted? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

For a site near Yelsted, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we will quote to suit.

Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or send details through our quote form and we will come back to it.

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Don’t wait for a second leak before calling
  • Add perimeter sealant to planned maintenance checks
  • Plan facade sealing alongside redecoration
  • Check the asbestos register before old mastic is disturbed

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

What sealant work can’t fix

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

  • Replacing glass or failed glazing units
  • Damp caused by condensation inside the building
  • Cracked or spalling substrates that need repair before sealing

If in doubt, phone 01277 525 020 or use the quote form and we will say what we think before you book.

Joints and surfaces we work on

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

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near Yelsted need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  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. 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.

Getting the site ready

  • Send any specification or drawings in advance
  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000

Questions we’re asked in Yelsted

Can you take on a job at a hospital such as KIMS hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Yelsted too small for you to travel to?

Not at all. Yelsted is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Who decides which product is used?

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.

Can you quote from photos?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.

How do I request a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Is it okay to overlay old mastic?

No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. Nothing else gives a bond that lasts.

Why it’s worth doing now in Yelsted

Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Older rural buildings around Yelsted move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

How the quote is worked out

Before we quote, we look at:

  • The size and state of each joint
  • How accessible the joints are
  • Working within restricted access windows
  • How much existing material needs removing

A quote for facade joints depends on how many there are, their condition and the access. Call for a quote.

Sending details for a quote

There’s no need for a formal survey. These details are enough to start:

  • Access details, including height
  • Where the site is, with the postcode
  • Approximate linear metres or a joint schedule
  • What the building is and how it’s used

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or email the details over.

Contractors’ notes for Yelsted

Yelsted is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Yelsted is about 33 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.

New wings at hospitals like KIMS hospital (to the south-west of Yelsted) bring long runs of window and panel joints to seal. New units and refits on sites such as Parkwood Shopping Centre (1.5 miles north-west of Yelsted) need their panel and perimeter joints sealed to the specification. School extensions, at buildings such as St Augustine of Canterbury Catholic Primary School, usually run to the summer holidays, mastic included.

Yelsted is about 3 miles south-east of Gillingham, in Kent. Anywhere in ME9, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 931 places in Kent, large and small. There’s a separate page for London, roughly 33 miles from Yelsted.
