Construction mastic in Blue Town

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Leave it or put it right?

Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple, with the same standard on every plot. In a smaller place such as Blue Town, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why appoint us

  • One phone line for London, the South East and Scotland
  • Health and safety: CHAS accredited
  • Specification-led, product-correct work
  • Over 20 years of commercial sealing

How we handle construction mastic in Blue Town

Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas, so applicators arrive when areas are genuinely ready. Sealing too early only means coming back once others have damaged it. We work on window and door perimeters, internal decorators’ caulk and cladding and panel joints, and what we are called in for most is missed perimeter joints on a new elevation and perimeter gaps outside the sealant’s range. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Blue Town, preparation and product choice get the time they need.

For a contractor on a smaller site near Blue Town, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Damage to finishes by other trades after we have sealed
  • Approving fire stopping as compliant

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think.

Joints and surfaces we work on

  • Window and door perimeters
  • Sanitary and kitchen joints
  • Internal decorators’ caulk
  • Brick and block movement joints
  • Cladding and panel joints
  • Floor and skirting junctions

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. For a job in Blue Town, the main thing is a clear picture of the work. You will then get a fixed price for the work.

  1. Drawings, specification and programme come to us.
  2. Quantities are measured and a fixed price returned.
  3. We agree with the site team which areas come first.
  4. Each area is sealed when it’s released.
  5. Joints are prepared, backed and sealed to the specification.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Preparing the site

  • Tell staff and tenants when we will be in
  • Move anything stored against the joints
  • Share your working hours and any access restrictions

Building owners, agents and FMs in Blue Town

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, and each stage is agreed with your contact.

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.

Sites and facades in and around Blue Town

The sea is no more than about 1 mile from Blue Town. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. At about 37 miles from central London, Blue Town is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.

Work at a hotel such as The Royal Fountain Hotel, less than half a mile to the south-west of Blue Town, tends to be programmed around bookings, mastic included. Recladding or extending a unit at a site like Neats Court Retail Park, 2.2 miles to the south of Blue Town, brings panel joints and frame perimeters into the programme. Extensions at sites like Sheppey Community Hospital (2.6 miles south-east of Blue Town) usually sit beside working departments, and the mastic follows strict access rules.

Blue Town is about 3 miles north-west of Minster, in Kent. Blue Town sits inside our coverage and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

Surface by surface

External facade and movement joints

External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies.

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.

Quoting for work in Blue Town

The price varies from site to site. It mainly depends on:

  • Induction, permit and paperwork requirements
  • Working within restricted access windows
  • The total length or number of joints
  • The size and state of each joint

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Before you send an enquiry

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

  • The postcode of the building
  • Access details, including height
  • Drawings or a marked-up plan, if available
  • The type of building and who uses it

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or email a schedule or drawings.

Where it’s specified, yes to the tested detail. If the detail calls for collars, wraps or batts instead, we will tell you.

What does a mastic package typically include?

The scope comes from the specification and drawings, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
