Sites and facades in and around Stonor
Rainfall across the South East, Stonor included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Stonor is about 37 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
With historic properties like Stonor Park (0.5 miles south-east of Stonor) in the area, refurbishment work often meets old masonry that needs compatible sealants.

How we handle facade sealing in Stonor
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on commercial buildings in Stonor. Coping and flashing joints are included where sealant is the specified fix. If you have weathered joints at frame-to-structure perimeters and staining on stone next to old sealant, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Stonor is the same: the right product in a properly prepared joint.
Sites around smaller places like Stonor can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Add perimeter sealant to planned maintenance checks
- Clear debris that holds water against joints
- Confirm the survey covers external sealants in older buildings
- Avoid patch repairs on failed facade joints
Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down and cuts time on site.
What we are called out for in Stonor
Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.
Common reasons buildings call us in:
- Hard, chalky sealant that no longer flexes
- Cold air coming in at window perimeters
- Leaks at window and door perimeters
- Failed seals around shopfront and entrance frames
On any site in or around Stonor, the mastic follows the specification and the programme.

Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Stonor can form part of a wider programme across Oxfordshire.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Stonor can be grouped with others nearby. You’ll have a fixed quote before work starts.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Before we start on site
- Send any specification or drawings in advance
- Send your site hours and access windows

FAQs: Stonor
What paperwork can you provide for a job in Stonor?
RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Can you keep pace with our programme in Stonor?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
How long do sealant joints last?
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.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you fit around our working hours?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Can you look at water coming in around a frame?
Yes. Photos help, and you can phone 01277 525 020 or email us to arrange a visit. Many frame leaks are sealant failures, though not all, and we will be honest about which it is.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Providing access systems for the work
- Water getting in through cracked render or porous masonry
- Cracked or spalling substrates that need repair before sealing
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly.
