Mastic sealing across Ashendon
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Looking after the joints
Regular inspection catches problems early. In particular:
- Look at the sunniest and most exposed elevations first
- Have the asbestos survey to hand for older buildings
- Make it easy for occupiers to report draughts
- List the paperwork your organisation requires when you send details
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Mastic sealing in Ashendon, done properly
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. We work on balcony and threshold joints, external wall and movement joints and communal entrances and stairwells, and what we are called in for most is communal area joints that look neglected and failed external movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ashendon, that means joint design, primers and backing rod as standard.
Owners and agents with buildings around smaller places such as Ashendon tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Why deal with it now?
Draughts round window perimeters cost occupiers comfort and the windows usually get the blame. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Around Ashendon, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Why us?
- Colours confirmed for the specified product
- Public liability insurance in place
- Sealing commercial buildings since 2005
- Coloured sealants to suit the setting, where available

Common questions from Ashendon clients
Is a smaller place like Ashendon outside your area?
Not at all. Ashendon is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
We manage a building near Haddenham & Thame Parkway station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Can you reseal a whole block or estate?
We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Frames that are rotten, warped or broken
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Glazing that needs replacing
Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly.
What we seal
- Communal kitchens and washrooms
- Communal entrances and stairwells
- External wall and movement joints
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks

Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. 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.
Cost factors for mastic joints
Each job is priced on its own details. The things that drive the figure:
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Working within restricted access windows
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Sending details for a quote
However big the job, these details speed things up:
- How the joints are reached, and at what height
- Any dates the work must fit around
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
To get a fixed quote, call 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
Frames, entrances and external joints in Ashendon
Ashendon lies roughly 44 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Blocks of flats and mixed-use buildings often cluster around stations such as Haddenham & Thame Parkway station (to the south-east of Ashendon) and their window and balcony mastic tends to age at the same rate across a building. If you own or manage units on a site such as Rushbeds Industrial Estate, 2.5 miles to the west of Ashendon, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Trustees of buildings like Parish Church of St Mary the Virgin can bring frame and external mastic into a planned maintenance list.
