About our mastic sealing in Beggar's Bush

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. Site teams most often ask us about open joints in brickwork or panels and occupiers reporting cold air round windows, across balcony and threshold joints, communal kitchens and washrooms and external wall and movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Beggar's Bush is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Beggar's Bush, 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 ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Signs you need mastic sealing in Beggar's Bush

Buildings move with temperature and moisture, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

Typical triggers for a call:

  • Old repairs sealed over failed mastic
  • Damaged joints in communal entrances and corridors
  • Brittle perimeter mastic across a building
  • Open joints in brickwork or panels

Older community buildings, Church of St Michael and All Angels among them, often have frames of mixed ages whose mastic varies.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • Whether primer will be used where the manufacturer specifies it
  • How they handle RAMS and site documents
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Owners, agents and contractors

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

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’ll confirm with the quote.

What the job involves on each surface

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and spreads the work.

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Questions about Beggar's Bush

Is Beggar's Bush too small for you to travel to?

No. Places such as Beggar's Bush are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you work for managing agents with blocks near Sunningdale station?

Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.

How do you handle work on occupied blocks?

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

How long does a job like this take?

It depends on the scope, but the work typically takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Doing it in-house

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Leaks through the frame itself rather than the perimeter
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Substrate edges that need repairing first

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
