Your questions answered
Is a smaller place like Great Missenden outside your area?
No. Small places get the same service as large ones. 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 Great Missenden station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can you reseal a whole block or estate?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Mastic sealing in Great Missenden: the local picture
Great Missenden sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building typically need attention first. Great Missenden lies roughly 30 miles out from central London. Managed blocks of flats are a big part of commuter-belt property.
Older community buildings, Church of Saints Peter and Paul among them, often have frames of mixed ages whose mastic varies. Owners of student blocks near Buckinghamshire New University (to the south-east of Great Missenden) can schedule frame and external mastic for the summer vacation. Blocks of flats and mixed-use buildings often cluster around stations such as Great Missenden station (under half a mile west of Great Missenden) and their window and balcony mastic tends to age at the same rate across a building.
Great Missenden is about 4 miles west of Chesham, in Buckinghamshire. We send applicators to Great Missenden for mastic joints, handled exactly as we handle every other area.

Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Great Missenden are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Tell us your opening times and when work is allowed
- Arrange parking or a loading space
- Tell staff and tenants when we’ll be in

What affects the price in Great Missenden
The price varies from site to site. Expect it to depend on:
- Working within restricted access windows
- Backing rod, priming and other preparation
- Access and working height
- Removal of failed or old sealant
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
What to include in your enquiry
A few photos plus some basic facts will normally do. Please tell us:
- The asbestos register, for older buildings
- The type of building and who uses it
- Approximate linear metres or a joint schedule
- When you need the work done
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Different surfaces, different methods
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
