About our mastic sealing in North Oxford
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you have patchy repairs in mismatched sealant and damaged joints in communal entrances and corridors, we can help, on window and door perimeters on blocks, external wall and movement joints and communal entrances and stairwells alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in North Oxford is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Owners with buildings around smaller places like North Oxford often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- The size and state of each joint
- Access and working height
- The product specified
- Quantities, in metres or numbers
Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Specification clauses that apply
- Anything awkward about access or site hours
- When you need the work done
- Drawings or a marked-up plan, if available
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Mastic sealing in North Oxford: the local picture
North Oxford is about 54 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. North Oxford is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building usually need attention first.
Buildings close to stations like Oxford station, 1.4 miles to the south of North Oxford, are often flats over shops, with frame mastic to keep sound. Student blocks close to universities like University of Oxford (to the south of North Oxford) are easiest to work on between tenancies.
North Oxford is about 2 miles north-west of Oxford, in Oxfordshire. Commercial clients in North Oxford can call on us for mastic joints. Across Oxfordshire, 423 places are covered, including North Oxford.

What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Misted or failed double-glazed units
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Asbestos-containing sealant, which we don’t remove
Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly before you book.
Joints and surfaces we work on
- Balcony and threshold joints
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- External wall and movement joints
- Shopfronts below residential blocks
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Group repairs into a planned programme
- Check the asbestos register before any old mastic is disturbed
- Reduce knocks to communal area joints
- Keep a record of when each building was resealed
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
When to call us in North Oxford
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
These are often picked up first by site or facilities staff:
- Movement joints with sealant missing
- Patchy repairs in mismatched sealant
- No planned programme for sealant
- Worn sealant at communal door frames
Schools and community buildings such as Oxford Academy need frame and external mastic kept sound like any building.

FAQs: North Oxford
Do you cover business parks and estates near North Oxford, such as Jordan Hill Business Park?
Yes. Our area takes in North Oxford and its surroundings, with estates and business parks such as Jordan Hill Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Is North Oxford too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Does weather matter for sealant work?
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. Inside work is seldom held up.
