How we handle facade sealing in Headington Hill
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. We work on perimeter joints where frames meet the structure, coping and flashing joints and stone and brick facade joints, and the failures we’re asked to look at most are hard, chalky sealant that no longer flexes and draughts around frames and panels. One point of contact handles commercial sealant work in Headington Hill from the first photographs to the final walk-round, whether it’s one building or several.
In a smaller place such as Headington Hill, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When to call us in Headington Hill
Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.
These are often picked up first by site or facilities staff:
- Perimeter joints where frames meet the structure
- Staining on stone next to old sealant
- Damp patches beside frames after rain
- Cladding panel joints that have opened up
For contractors at a college like Oxford Sixth Form College, 1.3 miles to the west of Headington Hill, perimeters and internal sealant are timed for the holidays.

- Their pre-qualification and accreditations
- Who will actually carry out the work
- Proof of insurance
Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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.
From enquiry to sign-off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. What matters most for a job in Headington Hill is a clear list of what needs doing. You will then get a fixed price for the work.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- 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
- Tell us your opening times and when work is allowed
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements

When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Render or concrete edges that have broken away
- Work on the window or framing system itself
- Joints too narrow for the movement they take, which need redesign
If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think.
What we seal
- Stone and brick facade joints
- Window and door perimeters
- Coping and flashing joints
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Shopfront frames
After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Avoid patch repairs on failed facade joints
- Plan facade sealing alongside redecoration
- Record the product and colour used on each elevation
- Don’t wait for a second leak before calling
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade instead of soaking the joints.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Are you CHAS accredited?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
