Construction mastic across Churchgate

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What sets the cost

Before we quote, we look at:

  • Whether the work must be split into stages
  • The size and state of each joint
  • The total length or number of joints
  • Whether old sealant has to be cut out first

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • The postcode of the building
  • When you need the work done
  • Photos of the joints, close up and from further back
  • Approximate linear metres or a joint schedule

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email the details over.

Construction mastic in Churchgate

We work to the specification and the programme rather than whatever product is to hand. Where the specification names a product, we use it. Backing, primer and depth follow what the sealant maker sets out. We work on window and door perimeters, floor and skirting junctions and internal decorators’ caulk, and the usual reasons a site gets in touch are external joints sealed in damp or cold conditions that are now failing and perimeter gaps outside the sealant’s range. For commercial sealant work in Churchgate, you deal with one contact from quote to sign-off, whether it’s one building or several.

On a small site around Churchgate, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Building and refurbishing in Churchgate

Several hotels sit less than 2 miles from Churchgate. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Churchgate is about 14 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

Historic houses such as Forty Hall, 2.5 miles to the south of Churchgate, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. School extensions, at buildings such as Dewhurst St Mary CofE Primary School, normally run to the summer holidays, mastic included. For contractors refurbishing units at places like Theobalds Enterprise Centre (0.6 miles south of Churchgate), the mastic covers cladding panels, roller-door and window perimeters.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking a day or two on a small fit-out and several weeks on a large multi-storey package. Several jobs near Churchgate can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We start with the drawings, specification and programme.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Plots or floors are sealed as they’re handed over.
  5. Joints are prepared, backed and sealed to the specification.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Point out parking and an unloading spot
  • Move anything stored against the joints

What sealant work can’t fix

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Joints damaged after sign-off by following trades
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Defective windows, doors or glazing units (the supplier or installer’s job)

If in doubt, call 01277 525 020 or email the details over and we’ll say what we think before you book.

Where we work in Churchgate

Questions we’re asked in Churchgate

Is Theobalds Enterprise Centre, near Churchgate, within your area?

Yes. Estates, retail parks and business parks around Churchgate, Theobalds Enterprise Centre among them, are all within reach. A few photos and the unit address let us price the work.

Do you take on work at healthcare sites like Cheshunt Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

How much does the work cost?

Each job is quoted on its own details. To get one, ring 01277 525 020 or email the details over with a description of the work.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

What the job involves on each surface

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.

External facade and movement joints

Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
