Construction mastic in Turnford

Mastic tends to be one of the final packages before handover, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers with projects in Turnford. If you have external joints sealed in damp or cold conditions that are now failing and a long mastic snag list close to completion, we can put it right, on window and door perimeters, brick and block movement joints and floor and skirting junctions alike. For commercial sealant work in Turnford, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Building work in places the size of Turnford is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Turnford can form part of a wider programme.

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.

Turnford: questions and answers

Can work at a site such as Hertford College: Broxbourne Campus fit around teaching?

Yes. Education sites normally 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 Turnford too small for you to travel to?

Not at all. Turnford is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Are you CHAS accredited?

Our applicators hold CSCS cards, and we are CHAS accredited and a Constructionline member. Public liability insurance of five million pounds is in place too.

Can you quote from photos?

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

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Will you quote for a small job?

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

How long does a typical visit take?

It depends on the scope, but the work typically takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Sites and facades in and around Turnford

Turnford is about 16 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Rainfall across the South East, Turnford included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.

When units on a site such as Brookfield Retail Park, 0.6 miles to the west of Turnford, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. When a school such as Longlands Primary School and Nursery is extended or refurbished, the mastic package is often squeezed into the holidays.

Turnford is about 1 mile north-east of Cheshunt, in Hertfordshire. Commercial clients in Turnford can call on us for mastic packages. Our Hertfordshire coverage takes in 371 places, from busy centres to rural villages. For work in that direction, see our London page.

Commercial sites across EN10 and EN8 are covered for mastic packages. If your site is on Groom Road, Yukon Road and Huron Road or close by, send details and we’ll quote for mastic packages. We also cover Wormley (1 mile north), Cheshunt (1 mile south-west), Holyfield (2 miles south-east), Churchgate (2 miles south-west) and Broxbourne (2 miles north). Bigger towns within reach include Stevenage (15 miles north-west), St Albans (13 miles west), Bishop's Stortford (13 miles north-east), Welwyn Garden City (9 miles north-west), Harpenden (15 miles north-west) and Hatfield (9 miles west).

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme, and we clear our waste as we work. Several jobs near Turnford can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. A fixed quote sets out the scope, the products and the sequence.
  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. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

Preparing the site

  • Flag any permit to work we will need
  • Move anything stored against the joints
  • Confirm the product named in the specification

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

Quoting for work in Turnford

Each job is priced on its own details. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • How much there is to seal
  • Which sealant the job calls for
  • Phasing around occupants

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • Anything awkward about access or site hours
  • The asbestos register, for older buildings
  • When you need the work done
  • The type of building and who uses it

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, call 01277 525 020 or email the details over.

Looking after the joints

To get the most from the new sealant:

  • Note which sealant went where at handover
  • Flag uneven or tapered frame gaps early
  • Ask cleaners to use soft cloths around fresh sealant
  • Use the product the specification names

Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead.

Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We raise them during our first walk of the area.

Common problems we fix in Turnford

Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.

Look out for the following:

  • Inconsistent sealant finishes from plot to plot
  • Frame perimeters left unsealed or poorly sealed
  • Failed sealant in an existing building being refurbished
  • Oversized or tapered gaps around new frames

For contractors at a college like Hertford College: Broxbourne Campus, which lies north of Turnford, perimeters and internal sealant are timed for the holidays.

Before you book anyone

  • Can the work be phased to keep areas open?
  • How the joint faces will be prepared and primed
  • What the guarantee covers, and for how long
  • Their pre-qualification and accreditations

How to choose a sealant contractor

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Oversized gaps that need packing or adjustment by others
  • Joint design decisions that belong to the architect or engineer
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)

If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.
