Mastic sealing for commercial buildings in Rough Common

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. The enquiries we see most involve occupiers reporting cold air round windows and no planned programme for sealant, across balcony and threshold joints, shopfronts below residential blocks and communal entrances and stairwells. Whoever orders the work in Rough Common, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places like Rough Common, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Our workmanship is guaranteed for 12 months, in Rough Common as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Signs you need mastic sealing in Rough Common

Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

Look out for the following:

  • Patchy repairs in mismatched sealant
  • Mastic failing across several blocks on an estate
  • Brittle perimeter mastic across a building
  • Complaints coming in block by block

Older community buildings, Church of St. Gabriel among them, often have frames of mixed ages whose mastic varies.

What your quote should include

  • How joint depth will be controlled
  • Their public liability cover
  • Do they follow the manufacturer’s priming guidance?
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone

What sets the cost

To price the job, we consider:

  • Working within restricted access windows
  • Travel to remote or island sites
  • Removal of failed or old sealant
  • Backing rod, priming and other preparation

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • The asbestos register, for older buildings
  • Approximate linear metres or a joint schedule
  • The site address and postcode
  • Photos of the joints, close up and from further back

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email a schedule or drawings.

Mastic sealing in Rough Common: the local picture

There are three care or nursing homes within about 2 miles of Rough Common. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. Rough Common sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.

Schools and community buildings such as Blean Primary School need frame and external mastic kept sound like any building. Property owners at sites such as Wincheap Industrial Estate, 1.6 miles south-east of Rough Common, can have mastic renewed between lettings.

Rough Common is about 2 miles north-west of Canterbury, in Kent. We send applicators to Rough Common for mastic joints. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, roughly 51 miles from Rough Common.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Protect low-level joints in entrances
  • Share your contractor requirements early
  • Avoid piecemeal callouts where you can
  • Include mastic in your cyclical inspections

If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it.

Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.

Building owners, agents and FMs in Rough Common

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Questions about Rough Common

Do you cover business parks and estates near Rough Common, such as Wincheap Industrial Estate?

Yes. Estates, retail parks and business parks around Rough Common, Wincheap Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Do you work in occupied care homes around Rough Common?

Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.

Will you just go over the old 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.

Can you take on resealing for a block portfolio?

Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

What do you charge?

Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or send details through our quote form with a description of the work.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Rough Common may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Move anything stored against the joints
  • Flag any permit to work we’ll need

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
