Mastic sealing in Fleet Marston, done properly
Older blocks and commercial buildings can have mastic that contains 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. If you are dealing with occupiers reporting cold air round windows and water getting in round frames after rain, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Fleet Marston, that means joint design, primers and backing rod as standard.
Rural conversions near places like Fleet Marston often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Questions we are asked in Fleet Marston
Is Fleet Marston too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
We manage a building near Aylesbury Vale Parkway station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What paperwork can you provide?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area.

However big the job, these details speed things up:
- Rough lengths or quantities, or drawings if you have them

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email drawings and photos.
Mastic sealing in Fleet Marston: the local picture
Fleet Marston is in the South East, one of the UK’s drier regions. 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. Two care or nursing homes sit less than 2 miles from Fleet Marston. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
For agents with blocks near Aylesbury Vale Parkway station, which lies east of Fleet Marston, a block-wide mastic programme deals with frames, balconies and entrances in one go. Landlords with units on estates such as Bicester Road Industrial Estate (1.3 miles south-east of Fleet Marston) can bring frame, door and external mastic across several units into one programme.
Fleet Marston is about 2 miles north-west of Aylesbury, in Buckinghamshire. Any commercial site in Fleet Marston is covered, for single jobs and planned programmes alike. We work across 308 places in Buckinghamshire, large and small. For work in that direction, see our Oxford page (17 miles or so).

When to call us in Fleet Marston
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
What tends to prompt an enquiry:
- Damaged joints in communal entrances and corridors
- Complaints coming in block by block
- A mix of products and colours from past repairs
- Open joints in brickwork or panels
Student blocks close to universities like University Campus Aylesbury Vale (2.8 miles south-east of Fleet Marston) are easiest to work on between tenancies.
Questions to ask before you book
- Is the sealant right for the movement and the substrate?
- Will CSCS-carded applicators be on site?
- How joint depth will be controlled
- Whether old or failed sealant will be cut out, not overlaid
Different surfaces, different methods
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.
Why it’s worth doing now in Fleet Marston
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Halls, stores and units around places like Fleet Marston may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What you get with us
