Look out for the following:

- Worn sealant at communal door frames

- Damp patches beside frames
If your remit includes a building such as Monks Risborough CofE Primary School, frame and door mastic can be programmed for the holidays.

Planned mastic for Askett portfolios
Central London is about 35 miles from Askett. Managed blocks of flats are a big part of commuter-belt property. Rainfall across the South East, Askett included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
For agents with blocks near Monks Risborough station, 0.5 miles south-west of Askett, a block-wide mastic programme deals with frames, balconies and entrances in one go. Older community buildings, Church of St Dunstan among them, often have frames of mixed ages whose mastic varies.

Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Substrate edges that need repairing first
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Balcony and threshold joints
- External wall and movement joints
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Communal kitchens and washrooms

Questions about Askett
Can one quote cover a number of our buildings near Askett?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photographs and we’ll give a fixed quote.
We manage a building near Monks Risborough station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.
Can you send RAMS and CSCS details before starting?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Is asbestos a concern with old mastic?
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.
Why it’s worth doing now in Askett
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. One visit to deal with every failing joint makes more sense than several trips to a place like Askett, rather than one at a time. Send photos of each area and we’ll quote for the lot.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why us?
- CSCS-carded applicators
- Colour agreed before work starts
- Specification-led, product-correct work
- CHAS accredited contractor
