For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Facade sealing in Birchington

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We build that into the programme and tell you if the forecast changes the plan. If you have gaps between rainscreen or cladding panels and weathered joints at frame-to-structure perimeters, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Birchington from the first photographs to the final walk-round, whether it’s one building or several.

Building work in places the size of Birchington is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in Birchington, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  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

  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints

FAQs: Birchington

Does your area include sites such as Manston Business Park, near Birchington?

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

Do you take on work at healthcare sites like Queen Elizabeth the Queen Mother Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

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 faces are cleaned before resealing. Nothing else gives a bond that lasts.

Leave it or put it right?

Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Building and refurbishing in Birchington

Birchington is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Birchington sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

For contractors at a school such as Birchington Church of England Primary School, sealing has to be finished before term starts. When units on a site such as Manston Business Park (1.9 miles south of Birchington) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For a contractor at a hotel such as Waterside Private Hotel, 1.4 miles east of Birchington, the mastic often has to be finished before a reopening date.

What sets the cost

What shapes the price:

  • Whether the work must be split into stages
  • Quantities, in metres or numbers
  • Removal of failed or old sealant
  • Joint width, depth and condition

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Access details, including height
  • Clear photos of the problem areas
  • What the building is and how it’s used
  • Specification clauses that apply

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, call 01277 525 020 or use the quote form.

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.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When it isn’t the sealant

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:

  • Providing access systems for the work
  • Cracked or spalling substrates that need repair before sealing
  • Joints too narrow for the movement they take, which need redesign

Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly.
