How we handle construction mastic in The Hythe

Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Most enquiries involve early adhesion failures on new external joints and sealant knocked or painted over by other trades, on floor and skirting junctions, sanitary and kitchen joints and brick and block movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in The Hythe is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Building work in places the size of The Hythe is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or send photos by email and we’ll come back to it.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a job in The Hythe, the main thing is a clear picture of the work. A fixed quote follows.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  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

  • Make sure the joints can be reached
  • Flag any permit to work we’ll need
  • Explain the parking and delivery arrangements

Related advice

Why deal with it now?

Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area normally clears more for less disruption. Snagging can be priced as a separate stage. For buildings in places like The Hythe, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why choose Mastic Doctor in The Hythe

The Hythe: questions and answers

Is The Hythe too far out for you?

Not at all. The Hythe is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

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

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you seal external joints in wet or cold weather?

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.

What does a mastic package normally include?

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

Can you fit around our programme?

The programme sets the job. Tell us the sequence and we’ll plan applicators around it, sealing as areas become ready.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Common problems we fix in The Hythe

Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.

If one of these sounds familiar, it’s time for a closer look:

  • New external sealant already peeling away
  • Caulk cracking where joints are moving more than expected
  • Window and door perimeters that won’t pass inspection
  • Perimeter gaps outside the sealant’s range

When units on a site such as Port Lane Industrial Estate, less than half a mile to the south-west of The Hythe, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

How to choose a sealant contractor

How the job changes by surface

Bathrooms, en suites and washrooms

Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent, plot by plot or floor by floor.

Snagging before handover

Snags usually come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit.

Site staff or a sealant specialist?

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 where general trades tend to cut corners.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Mastic packages on The Hythe sites

A 2-mile radius around The Hythe takes in a good number of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. The Hythe is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

Hospital estates such as Oaks Hospital (to the north-west of The Hythe) 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. Further education sites such as The Sixth Form College Colchester, 1.5 miles north-west of The Hythe, are extended and refurbished from time to time, with mastic often programmed into the summer break.

The Hythe is about 1 mile south-east of Colchester, in Essex. Businesses, contractors and managing agents in The Hythe can call on us for mastic packages. Across Essex, 644 places are covered, The Hythe among them. London is covered too, some 51 miles away.
