Mastic sealing in Molash, done properly

For blocks and buildings in Molash and across Kent, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. Most enquiries involve a mix of products and colours from past repairs and occupiers reporting cold air round windows, on balcony and threshold joints, communal entrances and stairwells and window and door perimeters on blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Molash, preparation and product choice get the time they need.

Rural conversions near places like Molash often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Why deal with it now?

Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Around Molash, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

Looking after buildings in and around Molash

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. Molash is about 47 miles from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.

For agents with blocks near Wye station, 3.2 miles to the south of Molash, a block-wide mastic programme deals with frames, balconies and entrances in one go. If you’re responsible for a building such as Church of St Peter, frame and door mastic needs the same attention as any other property.

Molash is about 6 miles south of Faversham, in Kent. Looking for mastic sealing in Molash? We can help, as we do across Kent. Molash is one of 931 places we cover in Kent for mastic joints. London is covered too, some 47 miles away.

Your questions answered

Is Molash too small for you to travel to?

No. Places such as Molash are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you quote for mastic across several buildings in and around Molash?

Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Will residents or tenants be disturbed?

Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.

Is asbestos a concern with old mastic?

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.

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

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

How long does a typical visit take?

It depends on the scope, but the work 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.

What the job involves on each surface

Window and door perimeters on blocks

Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.

Do you need mastic sealing in Molash?

Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. We’ll tell you if the joint edges need repairing before resealing.

Look out for the following:

  • Mastic failing across several blocks on an estate
  • Repeated reactive repairs to the same buildings
  • Movement joints with sealant missing
  • Cracked, hardened mastic round windows on a block

Historic properties like Belmont House and Gardens (to the north-west of Molash) show the age of some local stock, where frame mastic must suit soft brick or stone.

What to look for in a quote

  • Are they CHAS accredited or on Constructionline?
  • How the existing material will be dealt with
  • Their approach to joint depth and backing
  • The named product and why it was chosen

Questions to ask before you appoint anyone

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Water coming in from the roof or rainwater goods
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Misted or failed double-glazed units

Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly before you book.
