Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

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 usually costs more in the end than doing them right.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Quoting for work in Prestonville

Each job is priced on its own details. The main factors are:

  • Travel to remote or island sites
  • Joint width, depth and condition
  • Any access equipment needed
  • The product specified

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Whether an asbestos survey exists
  • Any specification or named product
  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or email a schedule or drawings with what you know.

FAQs: Prestonville

Is Prestonville too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Centenary Industrial Estate, by Prestonville?

Yes. Estates, retail parks and business parks around Prestonville, Centenary Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Do you do internal caulk as well as external mastic?

Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens, all priced as one package.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you use the sealant named in the specification?

The specification decides the product. Product standards such as BS EN 15651 are often named in specifications.

How much does the work cost?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

Different surfaces, different methods

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.

Window and door perimeters

Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified, and colour-matched products can be used where the frame is on show.

Why it’s worth doing now in Prestonville

It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Leave it late and they turn up on the snag list. For buildings in places like Prestonville, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

  • Colours chosen to suit frames, cladding or finishes where possible
