Construction mastic in Broom Street, done properly

Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place and gives you a consistent finish across the job. We work on brick and block movement joints, sanitary and kitchen joints and cladding and panel joints, and what we’re called in for most is a mastic package split between trades with no clear owner and frame perimeters left unsealed or poorly sealed. A specialist sealant contractor works differently from a general builder: in Broom Street, that means joint design, primers and backing rod as standard.

Around smaller places like Broom Street, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Broom Street, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we’ll be in
  • For older buildings, check the asbestos register before work

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Advice

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Rework caused by others damaging completed areas
  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)

If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Where we work in Broom Street

  • Cladding and panel joints

Sites and facades in and around Broom Street

Broom Street is within about 2 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. At about 46 miles from central London, Broom Street is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.

For contractors refurbishing units at places like Waterham Business Park, which lies east of Broom Street, the mastic covers cladding panels, roller-door and window perimeters. Projects at schools like Graveney Primary School work to term dates, so mastic is programmed tightly.

Broom Street is about 2 miles east of Faversham, in Kent. We cover Broom Street, with the same fixed quotes and 12-month guarantee as everywhere else. Broom Street is one of 931 places in Kent on our list for mastic packages. We also cover London, some 46 miles away.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Surface by surface

Window and door perimeters

Gaps around frames have to be within the sealant’s range. We check them during the first walk-round and flag any that need packing or adjusting.

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.

What we are called out for in Broom Street

Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Choosing the right product for each joint reduces that.

Typical triggers for a call:

  • Existing joints on a refurb that need cutting out and resealing
  • Snag items on joints that need redoing before handover
  • Cracks opening in caulked internal joints
  • New external sealant already peeling away

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

Before you book anyone

  • Their pre-qualification and accreditations
  • Will failed sealant be removed rather than covered?
  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards

Questions to ask before you appoint anyone

Your questions answered

Do you cover business parks and estates near Broom Street, such as Waterham Business Park?

Yes, sites like Waterham Business Park are within our area, along with the rest of Broom Street. A few photographs and the unit address let us price the work.

Our building in Broom Street is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Is Broom Street in your area?

Yes. Broom Street falls within our area, and you can call the office on 01277 525 020 or email drawings and photos to get started.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

How many days will you need on site?

It depends on the scope, though a typical visit typically takes whatever the programme allows, since the work follows the trades as areas are released. Larger or phased jobs take longer, and we will give you a timescale with the quote.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • How much existing material needs removing
  • Which sealant the job calls for
  • Distance, for remote addresses
  • How accessible the joints are

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Details that help us quote

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

  • Access details, including height
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or send photos by email.
