How we handle mastic sealing in Charlbury
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you have occupiers reporting cold air round windows and repeated reactive repairs to the same buildings, we can put it right. One point of contact handles commercial sealant work in Charlbury from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Converted and older buildings in and around Charlbury often put modern windows into old walls. The mastic there needs to suit both surfaces.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered
Is Southill Business Park, near Charlbury, within your area?
Yes. Estates, retail parks and business parks around Charlbury, Southill Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Will you take on a block within reach of Charlbury station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Can you take on resealing for a block portfolio?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
How long does a typical visit take?
It depends on the scope, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
What sets the cost
Each job is priced on its own details. The main factors are:
- How much there is to seal
- Joint width, depth and condition
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
There’s no need for a formal survey. A few details are enough to get going:
- When you need the work done
- Specification clauses that apply
- Photos of the joints, close up and from further back
- Access details, including height
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, speak to us on 01277 525 020 or email a schedule or drawings.
Commercial clients in Charlbury
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Charlbury. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Keeping the joints sound
Once the work is signed off, these steps help:
- Check sealant joints during planned building inspections
- Mention RAMS, insurance or CSCS requirements up front
- Plan resealing building by building rather than complaint by complaint
- Keep bins and bikes away from communal door frames
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Frames, entrances and external joints in Charlbury
Charlbury sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Charlbury is about 65 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
If your remit includes a building such as Charlbury Primary School, frame and door mastic can be programmed for the holidays. If you are responsible for a building such as St Mary's Church, frame and door mastic needs the same attention as any other property. For agents with blocks near Charlbury station (0.5 miles west of Charlbury), a block-wide mastic programme deals with frames, balconies and entrances in one go.

What happens if it’s left?
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work and less choice about when. For buildings in places like Charlbury, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
