Mastic sealing for businesses in Monk's Hill

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Mastic sealing for commercial buildings in Monk's Hill

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. We work on shopfronts below residential blocks, communal kitchens and washrooms and external wall and movement joints, and the usual reasons a site gets in touch are open joints in brickwork or panels and a mix of products and colours from past repairs. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Monk's Hill it comes down to the same thing: the right product in a properly prepared joint.

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

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

Why deal with it now?

Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Converted and older buildings near places like Monk's Hill tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What you get with us

  • Fully insured
  • Colour options checked against the specified product
  • Commercial sealant work since 2005
  • RAL and finish matching where the product range allows

See how commercial sealant jobs are priced and our accreditations.

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Keep bins and bikes away from communal door frames
  • Share your contractor requirements early
  • Keep a record of when each building was resealed
  • Ask residents or tenants to report leaks and draughts early

Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Common problems we fix in Monk's Hill

Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified it comes away from one face.

Look out for the following:

  • Brittle perimeter mastic across a building
  • Old repairs sealed over failed mastic
  • The same joint failures repeated across a portfolio
  • Occupiers reporting cold air round windows

If your remit includes a building such as Smarden Primary School, frame and door mastic can be programmed for the holidays.

Our contractor checklist

General trades versus a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Block-wide mastic in Monk's Hill

Monk's Hill is about 41 miles from central London. Managed blocks of flats are a big part of commuter-belt property. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

Blocks of flats and mixed-use buildings often cluster around stations such as Headcorn station (2.5 miles north-west of Monk's Hill) and their window and balcony mastic tends to age at the same rate across a building. Churches, halls and community buildings such as Church of St Michael are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Questions about Monk's Hill

Can one quote cover a number of our buildings near Monk's Hill?

Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photographs and we’ll give a fixed quote.

Is a smaller place like Monk's Hill outside your area?

Not at all. Monk's Hill is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you work with property factors and landlords?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can you send RAMS and CSCS details before starting?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Monk's Hill can be grouped with others nearby. You’ll have a fixed quote before work starts.
