About our construction mastic in Fleet Marston
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. We work on brick and block movement joints, cladding and panel joints and floor and skirting junctions, and what we’re called in for most is bath and shower joints scraped during the final clean and a long mastic snag list close to completion. A single leaking joint is often how a building in Fleet Marston first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Fleet Marston, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Contractors’ notes for Fleet Marston
Fleet Marston lies roughly 40 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Fleet Marston included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
For a contractor working at a hospital such as Royal Buckinghamshire Hospital (2.3 miles east of Fleet Marston), perimeter and facade sealing is planned around patients and deliveries. When a school such as Green Ridge Primary Academy is extended or refurbished, the mastic package is often squeezed into the holidays. Building work at universities like University Campus Aylesbury Vale, 2.8 miles to the south-east of Fleet Marston, is often timed for the summer, mastic included.
Fleet Marston is about 2 miles north-west of Aylesbury, in Buckinghamshire. Looking for construction mastic in Fleet Marston? We can help. Across Buckinghamshire, 308 places are covered, including Fleet Marston. For work in that direction, see our Oxford page (17 miles or so).

Surface by surface
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker and reduces snags.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.

How the quote is worked out
Each job is priced on its own details. The main factors are:
- The site’s rules and procedures
- Whether old sealant has to be cut out first
- Distance, for remote addresses
- The total length or number of joints
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 to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- Specification clauses that apply
- What the building is and how it’s used
- Any dates the work must fit around
- A wide shot and a close-up of the area
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Why deal with it now?
Patching snags as they appear can feel quicker than a proper close-out. But one planned snagging pass through each area usually clears more for less disruption. Snagging can be priced as a separate stage. Older rural buildings around Fleet Marston move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
A quote for mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Questions we’re asked in Fleet Marston
Do you cover business parks and estates near Fleet Marston, such as Bicester Road Industrial Estate?
Yes. Estates, retail parks and business parks around Fleet Marston, Bicester Road Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.
Is a hospital such as Royal Buckinghamshire Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
How long does a job like this take?
That varies with the scale of the job, though a typical visit typically takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you install fire-rated sealant as part of a package?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Tell us what records you need and we will confirm with the quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Looking after the joints
For the best life from the joints:
- Don’t schedule sealing before decorators and flooring are done
- Flag uneven or tapered frame gaps early
- Put any product change through the designer first
- Keep product details for future maintenance
After we’ve sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work, so we plan external work with that in mind.
When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Approving fire stopping as compliant
- Joint design decisions that belong to the architect or engineer
- Frame gaps too wide for sealant, which the installer needs to correct
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer.
