Construction mastic in Boars Hill
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you have frame perimeters left unsealed or poorly sealed and a mastic package split between trades with no clear owner, we can put it right, whatever the surface. Most enquiries from Boars Hill start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Conversions of older rural buildings near smaller places such as Boars Hill 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.
A 12-month guarantee applies to all our work in Oxfordshire. If an installation problem shows up, ring 01277 525 020 or use the quote form and we will arrange a return visit.

Construction mastic around Boars Hill: how the place shapes the job
Central London is about 53 miles from Boars Hill. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, Boars Hill included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
Projects at schools like Wootton St Peter's Church of England Primary School work to term dates, so mastic is programmed tightly. New wings at hospitals like Littlemore Hospital (2.8 miles east of Boars Hill) bring long runs of window and panel joints to seal.

When to call us in Boars Hill
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.
These are often picked up first by site or facilities staff:
- A long mastic snag list close to completion
- External joints sealed in damp or cold conditions that are now failing
- Old sealant on a refurbishment that needs stripping before new work
- A mastic package split between trades with no clear owner
For contractors refurbishing units at places like Wootton Business Park, 1.3 miles west of Boars Hill, the mastic covers cladding panels, roller-door and window perimeters.
What your quote should include
- How joint depth will be controlled
- Who will actually carry out the work
- How long is the guarantee, and what does it include?
- Do they follow the manufacturer’s priming guidance?
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Keeping the joints sound
To get the most from the new sealant:
- Keep product details for future maintenance
- Protect sealed areas from following trades
- Don’t force external sealing on a damp or frosty day
- Ask installers to correct oversized gaps first
A new structure shifts as it loses construction moisture. The right product in each joint copes with that while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks.
What the job involves on each surface
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification and set the depth with backing where needed.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. Joints are sealed smooth so they’re easy to clean.
Leave it or put it right?
Sealing over damaged or contaminated new joints might save a day. 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. Halls, stores and units around places like Boars Hill may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why us?
- RAL and finish matching where the product range allows
- Commercial sealant work since 2005
- Clear, fixed quotes
- Colours confirmed for the specified product

Your questions answered
Would you work within a site like Littlemore Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Boars Hill outside your area?
Not at all. Boars Hill is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Is the mastic package guaranteed?
It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Can the sealant be colour-matched?
It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
