Mastic sealing for businesses in Stubb's Cross

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

How we handle mastic sealing in Stubb's Cross

Managing agents and housing associations typically need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. If you have water getting in round frames after rain and the same joint failures repeated across a portfolio, we can put it right, on communal entrances and stairwells, shopfronts below residential blocks and balcony and threshold joints alike. Looking for mastic applicators who cover Stubb's Cross? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Rural conversions near places like Stubb's Cross often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Plan resealing building by building rather than complaint by complaint
  • Ask residents or tenants to report leaks and draughts early
  • Share the asbestos register when you send details
  • Check sealant joints during planned building inspections

Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.

Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.

Why deal with it now?

Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Older rural buildings around Stubb's Cross move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Planned mastic for Stubb's Cross portfolios

Central London is about 48 miles from Stubb's Cross. Managed blocks of flats are a big part of commuter-belt property. Stubb's Cross is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

Blocks of flats and mixed-use buildings often cluster around stations such as Ashford International station, 2.6 miles to the north-east of Stubb's Cross, and their window and balcony mastic tends to age at the same rate across a building. Historic properties like Godinton House, 3.3 miles to the north of Stubb's Cross, show the age of some local stock, where frame mastic must suit soft brick or stone. Property owners at sites such as Ellingham Industrial Estate, 1.4 miles to the north-east of Stubb's Cross, can have mastic renewed between lettings.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Broken glass or failed sealed units
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think before you book.

What we seal

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