Mastic sealing around Long Marston: points for this area
Long Marston is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Long Marston lies roughly 35 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
For owners of several units at places like Old Airfield Industrial Estate (1.1 miles east of Long Marston), one programme can deal with frame and external mastic across the lot. If you manage student housing near a university such as University Campus Aylesbury Vale, 4.8 miles to the west of Long Marston, the summer turnaround is the time for mastic. Trustees of buildings like Church of All Saints (Church of England) can bring frame and external mastic into a planned maintenance list.

Why act early in Long Marston
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Full removal and proper preparation is what lasts. Older rural buildings around Long Marston move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

What the job involves on each surface
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.
Tenement and older buildings
Older mastic can contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
Commercial clients in Long Marston
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Diagnose, treat, sign off
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Long Marston need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Share your working hours and any access restrictions

Advice
Long Marston: questions and answers
Will you take on a block within reach of Cheddington station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Do you cover business parks and estates near Long Marston, such as Old Airfield Industrial Estate?
Yes. We cover Long Marston and the area around it, including industrial estates, business parks and retail parks such as Old Airfield Industrial Estate. A few photographs and the unit address let us price the work.
Can you take on resealing for a block portfolio?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
How long does a job like this take?
It depends on the scope, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Leaks from above rather than through a joint
- Broken glass or failed sealed units
- Materials that need asbestos testing before work
If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
What we seal
- Balcony and threshold joints
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Communal entrances and stairwells
Site staff or a sealant specialist?
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.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
