Mastic sealing in Charndon
Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. If you’re dealing with the same joint failures repeated across a portfolio and communal area joints that look neglected, we can help, on balcony and threshold joints, shopfronts below residential blocks and external wall and movement joints alike. One point of contact handles commercial sealant work in Charndon from the first photos to the final walk-round, whether it’s one building or several.
Owners and agents with buildings around smaller places such as Charndon tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
A 12-month guarantee applies to all our work in Buckinghamshire. If an installation problem shows up, speak to us on 01277 525 020 or email the details over and we’ll arrange a return visit.

For owners and agents in Charndon
Rainfall across the South East, Charndon included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first. Central London is about 49 miles from Charndon. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
With historic buildings such as Claydon House (3 miles east of Charndon) in the wider area, owners of older properties around Charndon should expect mastic to need a product that suits old masonry. If you are responsible for a building such as Church of St Michael, frame and door mastic needs the same attention as any other property.

How the job changes by surface
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.
Tenement and older buildings
Stone needs a neutral-cure product and we choose accordingly.
Cost factors for mastic joints
Quotes vary with the job. It mainly depends on:
- Induction, permit and paperwork requirements
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
- Working within restricted access windows
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- Your programme or deadline
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
- Asbestos survey details if the building is older
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email a schedule or drawings.
Honest limits
Some faults sit outside our scope, and we say so rather than covering them up:
- Broken glass or failed sealed units
- Leaks through the frame itself rather than the perimeter
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer before you book.
Surfaces we seal
- Communal entrances and stairwells
- Balcony and threshold joints

How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Jobs in and around smaller places like Charndon are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
- Tell us which areas need to stay in use
