Facade sealing in Fair Oak
Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Site teams most often ask us about facade joints cracked through the middle and staining on stone next to old sealant, on shopfront frames, stone and brick facade joints and coping and flashing joints.

For a contractor on a smaller site near Fair Oak, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
Our workmanship is guaranteed for 12 months, in Fair Oak as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered
Does your area include sites such as Deer Park Farm Industrial Estate, near Fair Oak?
Yes, sites like Deer Park Farm Industrial Estate are within our area, along with the rest of Fair Oak. A few photographs and the unit address let us price the work.
Can you work around term dates at a campus such as Eastleigh College - Desborough Campus?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Do you replace windows or glass?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
How is access to upper-level joints handled?
We agree access with the client at the start. Tell us about access: existing scaffold, what you’re arranging and any site restrictions.
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Facades, frames and programmes in Fair Oak
Rainfall across the South East, Fair Oak 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 external mastic is timed for workable conditions and agreed with the site manager. Fair Oak lies roughly 64 miles out from central London. 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.
For a contractor working at a hospital such as Moorgreen Hospital, which lies south-west of Fair Oak, perimeter and facade sealing is planned around patients and deliveries. For contractors at a school such as Fair Oak Junior School, sealing has to be finished before term starts. For contractors refurbishing units at places like Deer Park Farm Industrial Estate, which lies east of Fair Oak, the mastic covers cladding panels, roller-door and window perimeters.

How the job changes by surface
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint rather than the system it surrounds.
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.
When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Installing or repairing glazing systems
- Water getting in through cracked render or porous masonry
- Specialist high-level access methods
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
What we seal
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Stone and brick facade joints
- Cladding panel joints
- Shopfront frames
- Window and door perimeters
After the work
Keep the joints in good shape with a few simple steps:
- Confirm the survey covers external sealants in older buildings
- Share access with other external trades
- Clear debris that holds water against joints
- Insist on a full cut-out when joints are renewed
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and our waste is bagged and taken away as we go. For a job in Fair Oak, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Point out any areas we must not close
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits
