How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Charlbury, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.

Advice
How we handle facade sealing in Charlbury
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear. We work on window and door perimeters, coping and flashing joints and stone and brick facade joints, and the usual reasons a site gets in touch are sealant pulling away from frames or panels and old perimeter mastic that has dried out. One point of contact handles commercial sealant work in Charlbury from the first photographs to the final walk-round, whether it’s one building or several.
Conversions around smaller places like Charlbury often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
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.

How the quote is worked out
We price every job individually. The things that drive the figure:
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
- Removal of failed or old sealant
- Joint width, depth and condition
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:
- Any specification or named product
- Where the site is, with the postcode
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Confirm the survey covers external sealants in older buildings
- Share access with other external trades
- Clear debris that holds water against joints
- Add perimeter sealant to planned maintenance checks
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Questions about Charlbury
Can you work to our programme on a site in or near Charlbury?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Charlbury off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Is it okay to overlay old mastic?
No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
Leave it or put it right?
Topping up a failed joint normally buys very little time. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Different surfaces, different methods
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them to the correct depth.
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in.

New build and refits around Charlbury
At about 65 miles from central London, Charlbury is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Charlbury is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
Projects at schools like Charlbury Primary School work to term dates, so mastic is programmed tightly. For contractors refurbishing units at places like Southill Business Park, which lies south of Charlbury, the mastic covers cladding panels, roller-door and window perimeters. Hotel extensions and refits, at places such as Bell Hotel, less than half a mile to the west of Charlbury, typically run between busy periods, so the sealing is squeezed into short windows.
