Facade sealing near West Street

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle facade sealing in West Street

Facade sealants sit in the sun, rain and frost every day, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. If you are dealing with perimeter sealant that has split or peeled away and cold air coming in at window perimeters, we can put it right, on shopfront frames, window and door perimeters and cladding panel joints alike. Facilities teams, main contractors and managing agents in West Street tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For a site near West Street, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered

Can you work around term dates at a campus such as Canterbury Christ Church University?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Does your area include sites such as Roebuck Business Park, near West Street?

Yes. We cover West Street and the area around it, including industrial estates, business parks and retail parks such as Roebuck Business Park. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

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’ll confirm the curing time on the day.

Can you work in cold or wet weather?

Rain and frost can pause external sealing. We plan for weather and keep you updated.

How long does a typical visit take?

That varies with the scale of the job, but the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we’ll set out a timescale with the quote.

How the job changes by surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and we’ll mention any edges that need repair.

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Joints too narrow for the movement they take, which need redesign
  • Render or concrete edges that have broken away
  • Replacing glass or failed glazing units

If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

What we seal

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

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. Rural sites near West Street may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Tell staff and tenants when we will be in
  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand

Advice

Facades, frames and programmes in West Street

Central London is about 39 miles from West Street. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. West Street 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.

Projects at schools like The Lenham School work to term dates, so mastic is programmed tightly. With historic properties like Leeds Castle (to the west of West Street) in the area, refurbishment work often meets old masonry that needs compatible sealants.

West Street is about 6 miles south of Sittingbourne, in Kent. Across the ME17 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • How much existing material needs removing
  • Location, for remote and island sites
  • How much there is to seal
  • Whether the work must be split into stages

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Details that help us quote

We can often quote from photographs and a few details. It helps to include:

  • How the joints are reached, and at what height
  • Specification clauses that apply
  • The postcode of the building
  • Photos of the joints, close up and from further back

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or send details through our quote form.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Building owners and managing agents use us on everything from one building to a spread of sites around West Street. One quote can cover more than one site, which keeps the paperwork simple.

Signs you need facade sealing in West Street

When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.

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

  • Weathered joints at frame-to-structure perimeters
  • Perimeter sealant that has split or peeled away
  • Water coming in around window frames
  • Hard, chalky sealant that no longer flexes

On a campus such as Canterbury Christ Church University, which lies north-west of West Street, new teaching buildings and residences are normally built and refurbished around the academic year.
