Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme, and we clear our waste as we work. Rural sites near High Cogges may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Before we start on site
- Arrange parking or a loading space
- Send any specification or drawings in advance
- Make sure the joints can be reached

Construction mastic in High Cogges
Mastic is often where a new building first shows its quality to the client. Untidy or missed joints are among the commonest snag items and clearing them late eats into the handover window. We seal so the snag list stays short, area by area through the programme. If you’re dealing with internal caulk splitting as the building dries out and oversized or tapered gaps around new frames, we can help, on brick and block movement joints, window and door perimeters and internal decorators’ caulk alike. Facilities teams, main contractors and managing agents in High Cogges tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as High Cogges 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.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Rework caused by others damaging completed areas
- Specifying the product where the designer hasn’t
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly before you book.
Surfaces we seal
- Window and door perimeters
- Floor and skirting junctions
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Brick and block movement joints
- Cladding and panel joints
Common problems we fix in High Cogges
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.
Clients normally get in touch after noticing one or more of the following:
- Frame perimeters left unsealed or poorly sealed
- A mastic package split between trades with no clear owner
- Snag items on joints that need redoing before handover
- Early adhesion failures on new external joints
Further education sites such as Abingdon & Witney College: Witney Campus (1.5 miles west of High Cogges) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Mastic packages on High Cogges sites
At about 61 miles from central London, High Cogges is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. High Cogges sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
For a contractor working at a hospital such as Witney Community Hospital, 1.6 miles to the west of High Cogges, perimeter and facade sealing is planned around patients and deliveries. When units on a site such as Wessex Industrial Estate (to the west of High Cogges) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
High Cogges is about 2 miles east of Witney, in Oxfordshire. We cover commercial sites throughout High Cogges, for single jobs and planned programmes alike. Our Oxfordshire coverage takes in 423 places, large and small. There’s a separate page for Oxford, roughly 10 miles from High Cogges.

Cost factors for mastic packages
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Backing rod, priming and other preparation
- The total length or number of joints
- The site’s rules and procedures
- Whether the work must be split into stages
Pricing mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.
What to include in your enquiry
A few photos plus some basic facts will normally do. Please tell us:
- Any dates the work must fit around

- Whether an asbestos survey exists
- What the building is and how it’s used
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
FAQs: High Cogges
Is Wessex Industrial Estate, near High Cogges, within your area?
Yes, sites like Wessex Industrial Estate are within our area, along with the rest of High Cogges. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.
Do you take on work at healthcare sites like Witney Community Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you use the sealant named in the specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
