Construction mastic across Phoenix Green

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

Cost factors for mastic packages

Before we quote, we look at:

  • Joint width, depth and condition
  • Whether the work must be split into stages
  • Which sealant the job calls for
  • How accessible the joints are

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

Details that help us quote

A few photographs plus some basic facts will normally do. It helps to include:

  • What the building is and how it’s used
  • The site address and postcode
  • The product your specification calls for
  • Drawings or a marked-up plan, if available

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

How we handle construction mastic in Phoenix Green

Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal areas can typically carry on while the outside waits. We work on window and door perimeters, cladding and panel joints and brick and block movement joints, and the failures we are asked to look at most are window and door perimeters that won’t pass inspection and a mastic package split between trades with no clear owner. Whoever orders the work in Phoenix Green, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Construction in and around smaller places such as Phoenix Green is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Leave it or put it right?

A quick bead over a damaged joint can get an area past inspection. Sealant can’t grip a contaminated or existing bead, and the defect comes back after handover. Damaged joints are removed and resealed from clean faces. Converted and older buildings near places like Phoenix Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Why us?

  • Standard and matched colours in many product ranges
  • Workmanship guaranteed for 12 months
  • Failed material removed, not covered up
  • One number for every site we cover

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Phoenix Green are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We walk the site or review drawings to understand the package.
  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. Any frame gaps or issues outside our scope are flagged to the site team.
  6. Final snagging is completed and the 12-month guarantee applies.

Preparing the site

  • Warn occupants and staff about the work
  • Move anything stored against the joints
  • Point out any areas we must not close

Getting a fixed quote

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or use the quote form to discuss it first.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Release areas for mastic once other trades have finished in them
  • Plan external elevations with the weather in mind
  • Record the products used in the O&M file
  • Keep scrapers and abrasive pads off new beads

A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.

External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Frame gaps too wide for sealant, which the installer needs to correct
  • Faulty frames rather than failed sealant
  • Damage to finishes by other trades after we’ve sealed

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.

Where we work in Phoenix Green

  • Sanitary and kitchen joints
  • Window and door perimeters

Construction mastic around Phoenix Green: points for this area

Phoenix Green is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. The area within 2 miles of Phoenix Green holds several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

For a contractor working at a hospital such as Fleet Community Hospital (2.7 miles east of Phoenix Green), perimeter and facade sealing is planned around patients and deliveries. When units on a site such as Winkworth Business Park, 0.6 miles west of Phoenix Green, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For contractors at a school such as Greenfields Junior School, sealing has to be finished before term starts.
