Mastic sealing across East Ashling

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Aftercare for building managers

Once the work is signed off, these steps help:

  • Log resealing dates block by block
  • Make mastic part of routine maintenance checks
  • Start inspections with the most exposed faces
  • Share the asbestos register when you send details

Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.

One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Mastic sealing in East Ashling, done properly

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. If you have no planned programme for sealant and leaks at window and door perimeters, we can help. Whoever orders the work in East Ashling, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like East Ashling, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

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

Common questions from East Ashling clients

Is East Ashling off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is Polthooks Farm Industrial Estate., near East Ashling, within your area?

Yes. Our area takes in East Ashling and its surroundings, with estates and business parks such as Polthooks Farm Industrial Estate. Included. Photos and a short description are enough for a first look.

Do you work for managing agents and housing associations?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Will residents or tenants be disturbed?

The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call the office on 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.

Do you check for asbestos in old sealant?

We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

When to call us in East Ashling

UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.

Look out for the following:

  • Damaged joints in communal entrances and corridors
  • Leaks at window and door perimeters
  • Window mastic that has split and shrunk
  • No planned programme for sealant

Churches, halls and community buildings such as Church of St Andrew are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • How they handle RAMS and site documents
  • How joint depth will be controlled
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

Why deal with it now?

Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. One visit to deal with every failing joint makes more sense than several trips to a place like East Ashling. Send photos of each area and we’ll quote for the lot.

Access often affects the price as much as the sealing: 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.
