Construction mastic for businesses in Row Green

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

Different surfaces, different methods

Window and door perimeters

Internal perimeters are typically sealed with a paintable product where decorating follows. The specification decides which.

Fire-rated sealant where specified

Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control and we install what’s specified.

About our construction mastic in Row Green

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. That keeps the work right first time and saves rework. We work on internal decorators’ caulk, window and door perimeters and brick and block movement joints, and the usual reasons a site gets in touch are cracks opening in caulked internal joints and window and door perimeters that won’t pass inspection. Most enquiries from Row Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Conversions of older rural buildings near smaller places such as Row Green bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Row Green need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First we take quantities off the drawings and read through the specification.
  2. You receive a fixed quote listing scope, products and phasing.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

Getting the site ready

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • Agree which areas must stay open

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Advice

Why deal with it now?

On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. We’ll say so if a frame itself is the problem. Halls, stores and units around places like Row Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Questions we are asked in Row Green

Will you plan work around the academic year at somewhere like Braintree College?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is hospital work, at somewhere like Braintree Community Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Can you fit around our programme?

We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start and adjusted as things change.

Do you do internal caulk as well as external mastic?

External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging in one fixed quote.

Can you come in just for snagging?

Yes. We clear snags by redoing joints rather than patching them.

When it isn’t the sealant

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
  • Damage to finishes by other trades after we’ve sealed
  • Joint design decisions that belong to the architect or engineer

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think.

Joints and surfaces we work on

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

Contractors’ notes for Row Green

Row Green is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 37 miles from Row Green. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

Hospital estates such as Braintree Community Hospital (to the north of Row Green) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. For contractors refurbishing units at places like Concord Farm Business Centre, which lies west of Row Green, the mastic covers cladding panels, roller-door and window perimeters.

Row Green is about 2 miles south-west of Braintree, in Essex. Our applicators travel to Row Green for work on mastic packages, handled exactly as we handle every other area. Row Green is one of 644 places in Essex on our list for mastic packages. For work in that direction, see our London page.

What sets the cost

To price the job, we consider:

  • The product specified
  • Distance, for remote addresses
  • How accessible the joints are
  • Whether the work must be split into stages

Pricing mastic packages depends on quantities, condition and access, and any specification that applies. Call for a quote.

Details that help us quote

However big the job, the same details help:

  • The site address and postcode
  • Asbestos survey details if the building is older
  • The type of building and who uses it
  • Photos of the joints, close up and from further back

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email a schedule or drawings.

Do you need construction mastic in Row Green?

Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.

Look out for the following:

  • Mastic snags holding up handover
  • Bath and shower joints scraped during the final clean
  • Cracks opening in caulked internal joints
  • Old sealant on a refurbishment that needs stripping before new work

For contractors at a school such as White Court School, sealing has to be finished before term starts.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Will CSCS-carded applicators be on site?
  • Their pre-qualification and accreditations
  • Do they follow the manufacturer’s priming guidance?
