Mastic sealing for commercial buildings in Ashdon

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. We work on window and door perimeters on blocks, communal entrances and stairwells and external wall and movement joints, and the failures we’re asked to look at most are leaks at window and door perimeters and brittle perimeter mastic across a building. A single leaking joint is often how a building in Ashdon 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.

Rural conversions near places like Ashdon 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.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Why it’s worth doing now in Ashdon

Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Older rural buildings around Ashdon move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why appoint us

  • Fixed quotes based on photographs, drawings or a visit
  • Old sealant cut out, never sealed over
  • Commercial sealant work since 2005
  • One number for every site we cover

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. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking one or more days per building, depending on the joint lengths and the access. For a building around Ashdon, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

What we need from you

  • Point out any areas we must not close
  • Move anything stored against the joints
  • Share your working hours and any access restrictions

Planned mastic for Ashdon portfolios

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 normally where frame mastic ages first. Ashdon is about 42 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.

Older community buildings, Church of All Saints among them, often have frames of mixed ages whose mastic varies. Schools and community buildings such as Ashdon Primary School need frame and external mastic kept sound like any building. With historic buildings such as Audley End House (4.7 miles south-west of Ashdon) in the wider area, owners of older properties around Ashdon should expect mastic to need a product that suits old masonry.

Ashdon is about 4 miles north-east of Saffron Walden, in Essex. Our applicators travel to Ashdon for work on mastic joints. We work across 644 places in Essex. For work in that direction, see our London page, about 42 miles away.

What affects the price in Ashdon

To price the job, we consider:

  • Distance, for remote addresses
  • Removal of failed or old sealant
  • The total length or number of joints
  • Working within restricted access windows

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • The site address and postcode
  • Anything awkward about access or site hours
  • Your programme or deadline
  • The type of building and who uses it

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, ring 01277 525 020 or use the quote form.

What we can’t put right

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Glazing that needs replacing
  • Substrate edges that need repairing first
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

How do you reach windows on upper floors?

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
