About our mastic sealing in Drayton St Leonard

Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. Site teams most often ask us about old repairs sealed over failed mastic and draught complaints from residents or tenants, on window and door perimeters on blocks, external wall and movement joints and balcony and threshold joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Drayton St Leonard is the same: the right product in a properly prepared joint.

For buildings around smaller places like Drayton St Leonard, we group work so one trip covers it. Send photographs of the frames and joints and we’ll give a fixed quote.

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.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Drayton St Leonard can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Getting the site ready

  • Flag any permit to work we will need
  • Have the specification and drawings to hand
  • Point out any areas we must not close

Advice

Building owners, agents and FMs in Drayton St Leonard

For main contractors, we work as the 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.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Drayton St Leonard can sit alongside others in a wider programme.

Aftercare for building managers

To get the most from the new sealant:

  • Protect low-level joints in entrances
  • Keep a record of when each building was resealed
  • Mention RAMS, insurance or CSCS requirements up front
  • Look at the sunniest and most exposed elevations first

Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.

One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.

What the job involves on each surface

Commercial and mixed-use buildings

Commercial occupiers typically stay open during the work so the work is phased.

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler and easier to manage.

Drayton St Leonard: questions and answers

Will you price a mastic programme across our Drayton St Leonard portfolio?

Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.

Is Drayton St Leonard off your patch?

No. Places such as Drayton St Leonard are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you supply RAMS and insurance details?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Do you work for managing agents and housing associations?

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

Do you check for asbestos in old sealant?

Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.

What guarantee do you give on resealing?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

How do you reach windows on upper floors?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.

What sealant work can’t fix

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

  • Failed window or door frames, which need a window contractor
  • 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 give us a call on 01277 525 020 or email us and we will tell you honestly.

Surfaces we seal

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

Planned mastic for Drayton St Leonard portfolios

Drayton St Leonard lies roughly 46 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

Historic properties like Clifton Hampden Manor (3.1 miles west of Drayton St Leonard) show the age of some local stock, where frame mastic must suit soft brick or stone. Buildings close to stations like Culham station, 4.3 miles to the west of Drayton St Leonard, are often flats over shops, with frame mastic to keep sound. Churches, halls and community buildings such as Church of St Leonard are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
