Facade sealing in Sidley, done properly

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. Site teams most often ask us about previous reseals run over old sealant and weathered joints at frame-to-structure perimeters, on shopfront frames, window and door perimeters and cladding panel joints. Facilities teams, main contractors and managing agents in Sidley tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

On a small site around Sidley, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Render or concrete edges that have broken away
  • Movement beyond what any sealant can handle
  • Water getting in through cracked render or porous masonry

If you are not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer.

Surfaces we seal

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

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Why deal with it now?

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once, saving a second set-up. For buildings in places like Sidley, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What you get with us

  • A Constructionline member, so easy to vet
  • Specification-led, product-correct work
  • RAL and finish matching where the product range allows
  • Colour agreed before work starts

New build and refits around Sidley

Sidley is within about 2 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

Projects at schools like All Saints Church of England Primary School work to term dates, so mastic is programmed tightly. For contractors refurbishing units at places like Elva Business Centre, which lies south of Sidley, the mastic covers cladding panels, roller-door and window perimeters. Extensions at sites like Bexhill Hospital, 0.7 miles to the south of Sidley, normally sit beside working departments, and the mastic follows strict access rules.

Sidley is about 1 mile north of Bexhill-on-Sea, in East Sussex. Sidley sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 308 places across East Sussex fall within our area, including Sidley. We also cover Brighton, around 26 miles from Sidley.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Any access equipment needed
  • Distance, for remote addresses
  • Which sealant the job calls for
  • Removal of failed or old sealant

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • The site address and postcode
  • The asbestos register, for older buildings
  • When you need the work done
  • Specification clauses that apply

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Questions we’re asked in Sidley

Will you plan work around the academic year at somewhere like Bexhill 6th Form College?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Does a coastal location like Sidley affect which sealant is used?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

Do you replace failed glazing units?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Should we check old sealant for asbestos?

In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. What matters most for a job in Sidley is a clear list of what needs doing, so send photographs of each area. You’ll then get a fixed price for the work.

  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. Failed beads are removed in full and the joint faces cleaned.
  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.

Getting the site ready

  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs

Different surfaces, different methods

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
