Construction mastic in Combe
Mastic tends to be one of the final packages before handover, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers on schemes in Combe. Site teams most often ask us about early adhesion failures on new external joints and frame perimeters left unsealed or poorly sealed, on cladding and panel joints, internal decorators’ caulk and brick and block movement joints. One point of contact handles commercial sealant work in Combe from the first photographs to the final walk-round, whether it’s one building or several.
For a site near Combe, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we’ll quote to suit.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What happens if it’s left?
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. We cut out and redo the joint properly. For buildings around smaller places like Combe, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
A quote for mastic packages depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Common problems we fix in Combe
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 typically get in touch after noticing one or more of the following:
- Early adhesion failures on new external joints
- Failed sealant in an existing building being refurbished
- Different trades sealing to different standards
- Missed perimeter joints on a new elevation
With historic properties like Blenheim Palace (to the east of Combe) in the area, refurbishment work often meets old masonry that needs compatible sealants.
Questions to ask before you book
- How joint depth will be controlled
- Whether their applicators hold CSCS cards
- How the joint faces will be prepared and primed
- Health and safety accreditation such as CHAS
Mastic packages on Combe sites
Combe sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. At about 61 miles from central London, Combe is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
School extensions, at buildings such as Combe CofE Primary School, typically run to the summer holidays, mastic included. When units on a site such as Wroslyn Road Industrial Estate (1.5 miles south of Combe) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Combe is about 5 miles north-east of Witney, in Oxfordshire. Anywhere in OX29, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 423 places across Oxfordshire fall within our area, including Combe. There’s a separate page for Oxford, about 10 miles away.

- The site’s rules and procedures
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

From enquiry to sign-off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Combe need work, visits can be combined. A fixed quote is given before anything starts.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Preparing the site
- Flag any permit to work we’ll need
- Confirm the product named in the specification
- Share the asbestos register for older buildings

Related advice
Combe: questions and answers
Is a smaller place like Combe outside your area?
Not at all. Combe is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work to our programme on a site in or near Combe?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
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.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Will you stick to the specified products?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
