How we handle mastic sealing in Steeple Claydon

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. Site teams most often ask us about estate-wide sealant that is simply worn out and damaged joints in communal entrances and corridors, across communal entrances and stairwells, external wall and movement joints 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: in Steeple Claydon, that means joint design, primers and backing rod as standard.

Older buildings and conversions around places like Steeple Claydon mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Substrate edges that need repairing first
  • Broken glass or failed sealed units
  • Materials that need asbestos testing before work

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think before you book.

Surfaces we seal

  • Window and door perimeters on blocks
  • Shopfronts below residential blocks
  • Communal kitchens and washrooms
  • Communal entrances and stairwells
  • Balcony and threshold joints
  • External wall and movement joints

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If neighbouring businesses or buildings around Steeple Claydon need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Preparing the site

Advice

Mastic sealing around Steeple Claydon: how the place shapes the job

Central London is about 49 miles from Steeple Claydon. Managed blocks of flats are a big part of commuter-belt property. Steeple Claydon is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.

For owners of several units at places like Three Bridge Mill Industrial Park, 1.6 miles to the west of Steeple Claydon, one programme can deal with frame and external mastic across the lot. With historic buildings such as Claydon House, 1.6 miles to the south-east of Steeple Claydon, in the wider area, owners of older properties around Steeple Claydon should expect mastic to need a product that suits old masonry.

Different surfaces, different methods

Planned maintenance

Resealing can be scheduled alongside other planned works on a timetable you set.

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.

Common problems we fix in Steeple Claydon

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Regular cleaning wears them further.

Look out for the following:

  • A mix of products and colours from past repairs
  • No planned programme for sealant
  • Damaged joints in communal entrances and corridors
  • The same joint failures repeated across a portfolio

Owners of student blocks near University of Buckingham (to the north of Steeple Claydon) can schedule frame and external mastic for the summer vacation.

How to choose a sealant contractor

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Aftercare for building managers

For the best life from the joints:

  • Mention RAMS, insurance or CSCS requirements up front
  • Track which buildings were done and when
  • Keep bins and bikes away from communal door frames
  • Have the asbestos survey to hand for older buildings

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. Resealing when cracking first shows avoids water damage and the complaints that come with it.
