Construction mastic across Clavering

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

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • 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

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think.

Where we work in Clavering

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

How we handle construction mastic in Clavering

Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. After that, the joints are prepared and sealed to the specification. If you are dealing with frame gaps too wide for sealant alone and a long mastic snag list close to completion, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Clavering tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Sites around smaller places like Clavering can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

New build and refits around Clavering

At about 34 miles from central London, Clavering is within reach of the capital. 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. Clavering is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

Units on estates such as Funstons Commercial Centre (0.8 miles north-east of Clavering) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. School extensions, at buildings such as Clavering Primary School, normally run to the summer holidays, mastic included.

Clavering is about 6 miles south-west of Saffron Walden, in Essex. Our applicators travel to Clavering for work on mastic packages, handled exactly as we handle every other area. Our Essex coverage takes in 644 places, large and small. For work in that direction, see our London page, about 34 miles away.

Commercial sites across CB11 are covered for mastic packages. For a building on High Street, Skeins Way and Chapel Close or nearby, send details and we will quote for mastic packages. Close to Clavering, our area also takes in Hill Green (1 mile north-east), Starling's Green (1 mile west), Berden (1 mile south), Wicken Bonhunt (2 miles north-east) and Arkesden (2 miles north-east).

Clavering: questions and answers

Does your area include sites such as Funstons Commercial Centre, near Clavering?

Yes. Estates, retail parks and business parks around Clavering, Funstons Commercial Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can you work to our programme on a site in or near Clavering?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

What guarantee comes with a mastic package?

It carries a 12-month guarantee on our workmanship. We’re also fully insured for public liability.

What do you charge?

Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email us.

Does weather affect external mastic work?

Outside, the joint has to be dry and the temperature within the product’s limits. Damp, frost or condensation on frames can stop work, so internal areas are often done on those days.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Doing it in-house

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Get the mastic subcontractor involved early in the programme
  • Stick to the specified sealant rather than a generic substitute
  • Release areas for mastic once other trades have finished in them
  • Brief following trades on areas that have been sealed

At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. We can confirm the handover information you need when we quote.

Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Clavering, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We price from the drawings, specification and programme you send.
  2. We return a fixed quote that ties the mastic package to your programme.
  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. We close out snagging and hand over with a 12-month guarantee.

Preparing the site

  • Arrange parking or a loading space
