Mastic sealing in Great Hampden
Across Great Hampden and the rest of Buckinghamshire, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. Most enquiries involve damp patches beside frames and draughts at frames across a block, across balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells. Whether you call it commercial sealant work, mastic application or joint sealing, in Great Hampden it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Great Hampden, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Why deal with it now?
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. One visit to deal with every failing joint makes more sense than several trips to a place like Great Hampden, rather than one at a time. Photos of every joint help us quote for the whole job.
Pricing mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Great Hampden need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Send any specification or drawings in advance
- Share your working hours and any access restrictions

Keeping the joints sound
To get the most from the new sealant:
- Keep bins and bikes away from communal door frames
- Avoid piecemeal callouts where you can
- Ask residents or tenants to report leaks and draughts early
- Look at the sunniest and most exposed elevations first
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
What affects the price in Great Hampden
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Whether the work must be split into stages
- How much there is to seal
- Site requirements such as inductions and permits
- Removal of failed or old sealant
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
A few photographs plus some basic facts will normally do. Please tell us:
- Where the site is, with the postcode
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
- Any dates the work must fit around
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call 01277 525 020 or email drawings and photos if you’d rather talk the job through.

- Glazing that needs replacing

Blocks and managed buildings in Great Hampden
At about 32 miles from central London, Great Hampden is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Great Hampden sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
Churches, halls and community buildings such as Church of St Mary Magdalene are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Historic properties like Hughenden Manor (to the south of Great Hampden) show the age of some local stock, where frame mastic must suit soft brick or stone. Blocks of flats and mixed-use buildings often cluster around stations such as Great Missenden station (2.6 miles east of Great Hampden) and their window and balcony mastic tends to age at the same rate across a building.
Great Hampden is about 5 miles north of High Wycombe, in Buckinghamshire. Commercial clients in Great Hampden use us for work on mastic joints, as part of our coverage of Buckinghamshire.

What the job involves on each surface
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Planned maintenance
We can work into your cyclical maintenance plan, building by building.
Your questions answered
We manage a building near Great Missenden station. Can you help?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Crownfield Industrial Estate, near Great Hampden, within your area?
Yes. Estates, retail parks and business parks around Great Hampden, Crownfield Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
