Mastic sealing for commercial buildings in Hazlemere
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. The enquiries we see most involve cracked, hardened mastic round windows on a block and complaints coming in block by block, on shopfronts below residential blocks, communal kitchens and washrooms and window and door perimeters on blocks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hazlemere it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Places the size of Hazlemere normally have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.
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.

Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Share the asbestos register when you send details
- Group repairs into a planned programme
- Make mastic part of routine maintenance checks
- Keep bins and bikes away from communal door frames
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.

When to call us in Hazlemere
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Site and facilities staff are often the first to spot these:
- Patchy repairs in mismatched sealant
- Brittle perimeter mastic across a building
- Draughts at frames across a block
- Communal area joints that look neglected
If you look after a block within reach of High Wycombe station (2.1 miles south-west of Hazlemere), frame and balcony mastic can be renewed on one programme.

Block-wide mastic in Hazlemere
Hazlemere lies roughly 28 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide. Hazlemere is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Churches, halls and community buildings such as Holy Trinity Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If your remit includes a building such as Sir William Ramsay School, frame and door mastic can be programmed for the holidays.

What happens if it’s left?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Pricing mastic joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
