What we’re called out for in Whiteleaf
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.
Common reasons buildings call us in:
- Window mastic that has split and shrunk
- Occupiers reporting cold air round windows
- No planned programme for sealant
- Open joints in brickwork or panels
Blocks of flats and mixed-use buildings often cluster around stations such as Monks Risborough station, 0.7 miles west of Whiteleaf, and their window and balcony mastic tends to age at the same rate across a building.
Before you book anyone
- The named product and why it was chosen

- Will RAMS and insurance details be available?

Your questions answered
Is Whiteleaf off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you work for managing agents with blocks near Monks Risborough station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Broken glass or failed sealed units
- Failed window or door frames, which need a window contractor
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think before you book.
Joints and surfaces we work on
- Communal entrances and stairwells
- External wall and movement joints

Planned mastic for Whiteleaf portfolios
The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 35 miles from Whiteleaf. 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.
Older community buildings, Church of St Dunstan among them, often have frames of mixed ages whose mastic varies. Site managers at schools like Monks Risborough CofE Primary School can fit frame mastic into the summer works.

What happens if it’s left?
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. Converted and older buildings near places like Whiteleaf tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

How the quote is worked out
We price every job individually. The things that drive the figure:
- How much there is to seal
- Working within restricted access windows
- Which sealant the job calls for
- The site’s rules and procedures
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Before you send an enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- What the building is and how it’s used
- Access details, including height
- The product your specification calls for
- Asbestos survey details if the building is older
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Plan resealing building by building rather than complaint by complaint
- Track which buildings were done and when
- Include mastic in your cyclical inspections
- List the paperwork your organisation requires when you send details
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Rural sites near Whiteleaf may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Arrange parking or a loading space
- Have the specification and drawings to hand
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
