How we handle mastic sealing in Broad Oak

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. We work on shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells, and the failures we are asked to look at most are estate-wide sealant that is simply worn out and movement joints with sealant missing. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Broad Oak, preparation and product choice get the time they need.

For buildings around smaller places like Broad Oak, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Should maintenance staff do it?

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.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Questions we are asked in Broad Oak

Is Broad Oak off your patch?

Not at all. Broad Oak is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Do you work for managing agents with blocks near Winchfield station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How do you handle work on occupied blocks?

Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Share your contractor requirements early
  • Group repairs into a planned programme
  • Keep a record of when each building was resealed
  • Start inspections with the most exposed faces

Where a paintable product was specified, it can be painted after curing. Silicone normally can’t be painted, so keep decorators off it unless told otherwise.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

Different surfaces, different methods

Communal areas

Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.

Estate-wide resealing programmes

An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Broad Oak can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we look at the mastic on each building and note what needs replacing.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints

Ask for a quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Advice

Block-wide mastic in Broad Oak

Broad Oak lies roughly 39 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Schools and community buildings such as Mayhill Junior School need frame and external mastic kept sound like any building. Landlords with units on estates such as Murrell Green Business Park (2.1 miles north of Broad Oak) can bring frame, door and external mastic across several units into one programme. Churches, halls and community buildings such as All Saints Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
