Honest limits

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

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Installing or repairing glazing systems
  • Joints whose design needs changing by the specifier

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly.

What we seal

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

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Facade sealing around Broom Street: how the place shapes the job

Broom Street lies within about 2 miles of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Broom Street is about 46 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

When a school such as Graveney Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. When units on a site such as Waterham Business Park (to the east of Broom Street) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Broom Street is about 2 miles east of Faversham, in Kent. We send applicators to Broom Street for facade joints. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, roughly 46 miles from Broom Street.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically 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. For a building around Broom Street, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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 and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

  • Send any specification or drawings in advance
  • Send asbestos survey details if the building is pre-2000
  • Tell us which areas need to stay in use

Broom Street: questions and answers

Would you work within a site like Whitstable and Tankerton Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will you take on work at estates like Waterham Business Park, close to Broom Street?

Yes. Estates, retail parks and business parks around Broom Street, Waterham Business Park among them, are all within reach. A few photos and the unit address let us price the work.

Can you find out why a window is leaking?

Yes. Photos help, and you can phone 01277 525 020 or send photos by email to arrange a visit. Many frame leaks are sealant failures, though not all, and we’ll be honest about which it is.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.

How do I request a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or send photos by email. Include photographs or drawings if you have them.

Do we need an asbestos check before resealing?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. Suspect material is left alone until it has been tested.

How the job changes by surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Precast concrete panels

Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

When to call us in Broom Street

When the sealant tears down its centre, it has typically been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

It’s worth sending us details if you spot any of the following:

  • Failed seals around shopfront and entrance frames
  • Unsightly perimeter sealant on a visible elevation
  • Water coming in around window frames
  • Old perimeter mastic that has dried out

New wings at hospitals like Whitstable and Tankerton Hospital, 5.6 miles to the north-east of Broom Street, bring long runs of window and panel joints to seal.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • The terms of the workmanship guarantee
  • Their pre-qualification and accreditations
  • Which product they’ll use, and why it suits the joint
