About our mastic sealing in Bircholt Forstal

Across Bircholt Forstal and the rest of Kent, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. The enquiries we see most involve water getting in round frames after rain and repeated reactive repairs to the same buildings, on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints. Most enquiries from Bircholt Forstal start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Bircholt Forstal, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered

Is Bircholt Forstal too far out for you?

Not at all. Bircholt Forstal is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on a block within reach of Westenhanger station?

Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

Can you work to our specification?

Yes. Send it with your enquiry, and we will price the work to it.

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 communal access is kept open.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Commercial clients in Bircholt Forstal

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For a building around Bircholt Forstal, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Preparing the site

Mastic sealing in Bircholt Forstal: the local picture

Bircholt Forstal lies roughly 53 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Bircholt Forstal included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.

For a school such as Brabourne Church of England Primary School, perimeter mastic on windows and doors is a holiday job. Older buildings near Bircholt Forstal, from historic houses such as Westenhanger Castle (to the south-east of Bircholt Forstal) to more modest stock, need compatible products when frames are resealed.

Bircholt Forstal is about 5 miles east of Ashford, in Kent. Across the TN25 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

Common problems we fix in Bircholt Forstal

Occasionally the substrate fails, not the sealant for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.

Clients usually get in touch after noticing one or more of the following:

  • A mix of products and colours from past repairs
  • Draughts at frames across a block
  • Movement joints with sealant missing
  • No planned programme for sealant

If you look after a block within reach of Westenhanger station, which lies south-east of Bircholt Forstal, frame and balcony mastic can be renewed on one programme.

Questions to ask before you book

  • Proof of insurance
  • How joint depth will be controlled
  • Will CSCS-carded applicators be on site?
  • How long is the guarantee, and what does it include?

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
