How we handle mastic sealing in Bucks Green

Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. If you are dealing with water getting in round frames after rain and worn sealant at communal door frames, we can help, on external wall and movement joints, balcony and threshold joints and shopfronts below residential blocks alike. A single leaking joint is often how a building in Bucks Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Bucks Green, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Blocks and managed buildings in Bucks Green

At about 33 miles from central London, Bucks Green is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide. Bucks Green is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.

If your remit includes a building such as Pennthorpe School, frame and door mastic can be programmed for the holidays. Churches, halls and community buildings such as St John the Baptist are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Bucks Green is about 6 miles west of Horsham, in West Sussex. We cover commercial sites throughout Bucks Green, whether it’s a single job or part of a planned programme. Our West Sussex coverage takes in 373 places. There’s a separate page for Brighton, about 23 miles away.

Anyone looking for mastic sealing in RH12 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

After the work

After handover, these steps help:

  • Make it easy for occupiers to report draughts
  • Make mastic part of routine maintenance checks
  • Avoid piecemeal callouts where you can
  • Mention RAMS, insurance or CSCS requirements up front

Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.

Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Building owners, agents and FMs in Bucks Green

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Bucks Green can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Warn occupants and staff about the work

Bucks Green: questions and answers

Does your area include sites such as The Old Brickworks Industrial Estate, near Bucks Green?

Yes. We cover Bucks Green and the area around it, including industrial estates, business parks and retail parks such as The Old Brickworks Industrial Estate. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Will you take on a block within reach of Christs Hospital station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

How do you reach windows on upper floors?

We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.

Can you reseal a whole block or estate?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Do you check for asbestos in old sealant?

Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How the quote is worked out

Quotes vary with the job. Expect it to depend on:

  • Distance, for remote addresses
  • How much existing material needs removing
  • Joint width, depth and condition
  • Induction, permit and paperwork requirements

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

We can often quote from photos and a few details. It helps to include:

  • Whether an asbestos survey exists
  • Your programme or deadline
  • A wide shot and a close-up of the area
  • Where the site is, with the postcode

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Common problems we fix in Bucks Green

Many failed joints were sealed without backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and splits as the building moves.

Look out for the following:

  • Complaints coming in block by block
  • Communal area joints that look neglected
  • Open joints in brickwork or panels
  • Draughts at frames across a block

For agents with blocks near Christs Hospital station, which lies south-east of Bucks Green, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Before you book anyone

  • What site paperwork they can supply
  • Their plan for phasing and protecting the area
  • Whether primer will be used where the manufacturer specifies it
  • Will CSCS-carded applicators be on site?
