Gill's Green: questions and answers

Is Gill's Green too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Does your area include sites such as Hawkhurst Station Business Park, near Gill's Green?

Yes. We cover Gill's Green and the area around it, including industrial estates, business parks and retail parks such as Hawkhurst Station Business Park. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is asbestos a concern with old mastic?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.

Do you guarantee the mastic work?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Can you send RAMS and CSCS details before starting?

We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Will residents or tenants be disturbed?

We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.

About our mastic sealing in Gill's Green

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 and we quote and schedule each building in turn. We work on balcony and threshold joints, external wall and movement joints and shopfronts below residential blocks, and what we’re called in for most is water getting in round frames after rain and cracked, hardened mastic round windows on a block. For commercial sealant work in Gill's Green, you deal with one contact from quote to sign-off, whether it’s one building or several.

For owners with a single building near Gill's Green, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Look at the sunniest and most exposed elevations first
  • Share the asbestos register when you send details
  • Log resealing dates block by block
  • Protect low-level joints in entrances

Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.

Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.

Different surfaces, different methods

Commercial and mixed-use buildings

Commercial occupiers typically stay open during the work, so we plan around them.

Communal areas

We keep entrances and stairs open throughout. Work is planned in sections.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Masonry that has broken away beside the joint
  • Misted or failed double-glazed units
  • Materials that need asbestos testing before work

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

Surfaces we seal

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

Owners, agents and contractors

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Gill's Green can form part of a wider programme across Kent.

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.

Block-wide mastic in Gill's Green

Gill's Green sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. At about 40 miles from central London, Gill's Green is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.

If you own or manage units on a site such as Hawkhurst Station Business Park, which lies north of Gill's Green, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Older community buildings, Church of All Saints among them, often have frames of mixed ages whose mastic varies. Older buildings near Gill's Green, from historic houses such as Scotney Castle, 4.8 miles to the north-west of Gill's Green, to more modest stock, need compatible products when frames are resealed.
