Great Missenden: questions and answers
Will you plan work around the academic year at somewhere like Buckinghamshire New University?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Great Missenden too far out for you?
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.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you just add new sealant on top?
No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
Facade sealing in Great Missenden
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have hard, chalky sealant that no longer flexes and perimeter sealant that has split or peeled away, we can put it right, on stone and brick facade joints, shopfront frames and coping and flashing joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Great Missenden it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Conversions of older rural buildings near smaller places such as Great Missenden bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Replacing glass or failed glazing units
- Cracked or spalling substrates that need repair before sealing
- Water getting in through cracked render or porous masonry
If you’re not sure, just call 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
Surfaces we seal
- Stone and brick facade joints
- Shopfront frames
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Cladding panel joints
- Window and door perimeters
After the work
Once the work is signed off, a little attention goes a long way:
- Avoid harsh cleaners on facade sealant
- Add perimeter sealant to planned maintenance checks
- Confirm the survey covers external sealants in older buildings
- Insist on a full cut-out when joints are renewed
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards using a matching sealant.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
When to call us in Great Missenden
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.
Site and facilities staff are often the first to spot these:
- Unsightly perimeter sealant on a visible elevation
- Leaks at window and door perimeters
- Weathered facade joints that have lost their grip
- Gaps between rainscreen or cladding panels
For contractors on a campus like Buckinghamshire New University, 3 miles south-east of Great Missenden, facade and perimeter sealing has to fit around students and term dates.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether old or failed sealant will be cut out, not overlaid
- How long is the guarantee, and what does it include?

What else we do in Great Missenden
Surface by surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod, primed where the maker specifies.
Facade sealing in Great Missenden: the local picture
Great Missenden is about 30 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Great Missenden is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
For a contractor working at a hospital such as The Chiltern Hospital (1.1 miles south-east of Great Missenden), perimeter and facade sealing is planned around patients and deliveries. With historic properties like Hughenden Manor, 4.2 miles south-west of Great Missenden, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Cost factors for facade joints
We price every job individually. The things that drive the figure:
- Location, for remote and island sites
- The product specified
- Induction, permit and paperwork requirements
- How much existing material needs removing
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
