Looking after buildings in and around Boughton Malherbe

Boughton Malherbe is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first. Central London is about 39 miles from Boughton Malherbe. 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.

Student blocks close to universities like Canterbury Christ Church University (to the north of Boughton Malherbe) are easiest to work on between tenancies. Property owners at sites such as Roebuck Business Park (2.1 miles north-west of Boughton Malherbe) can have mastic renewed between lettings.

Mastic sealing in Boughton Malherbe

In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you are dealing with leaks at window and door perimeters and cracked, hardened mastic round windows on a block, we can help, on shopfronts below residential blocks, balcony and threshold joints and window and door perimeters on blocks alike. A single leaking joint is often how a building in Boughton Malherbe first comes to us: we look at the rest while we’re there and tell you what we find.

In and around smaller places like Boughton Malherbe, 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.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, call the office on 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Surface by surface

External movement joints

Joint size and product are matched to the expected movement with the width-to-depth ratio set as the manufacturer advises.

Tenement and older buildings

Natural stone can be marked by the wrong sealant and we choose accordingly.

What we’re called out for in Boughton Malherbe

Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Cleaning products add to the wear.

Clients usually get in touch after noticing one or more of the following:

  • Occupiers reporting cold air round windows
  • Damaged joints in communal entrances and corridors
  • Estate-wide sealant that is simply worn out
  • Patchy repairs in mismatched sealant

If you’re responsible for a building such as Church of St Nicholas, frame and door mastic needs the same attention as any other property.

Comparing quotes

  • Health and safety accreditation such as CHAS
  • Do they follow the manufacturer’s priming guidance?
  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

What affects the price in Boughton Malherbe

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

  • Access and working height
  • The size and state of each joint
  • Whether old sealant has to be cut out first
  • Working within restricted access windows

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • The postcode of the building
  • When you need the work done
  • Clear photographs of the problem areas
  • How the joints are reached, and at what height

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Masonry that has broken away beside the joint
  • Leaks from above rather than through a joint
  • Failed window or door frames, which need a window contractor

If you’re not sure, just call 01277 525 020 or email us and we’ll give you a straight answer before you book.

Advice

Questions we are asked in Boughton Malherbe

Does your area include sites such as Roebuck Business Park, near Boughton Malherbe?

Yes. Estates, retail parks and business parks around Boughton Malherbe, Roebuck Business Park among them, are all within reach. Photos and a short description are enough for a first look.

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

Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

How long does a job like this take?

That varies with the scale of the job, though a typical visit normally takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Is Boughton Malherbe in your area?

Yes. Boughton Malherbe is in our area and the rest of Kent. For a quote, give us a call on 01277 525 020 or send details through our quote form.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What if the old mastic contains asbestos?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.

Why act early in Boughton Malherbe

Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee. Halls, stores and units around places like Boughton Malherbe may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Why choose Mastic Doctor in Boughton Malherbe

  • Colours chosen to suit frames, cladding or finishes where possible
  • A range of standard colours, depending on the product
  • Public liability insurance in place
  • A fixed quote before work starts
