Mastic sealing for Fencott sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Why deal with it now?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and normally fails within a short time. Full removal and proper preparation is what lasts. Around Fencott, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

About our mastic sealing in Fencott
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. The enquiries we see most involve complaints coming in block by block and open joints in brickwork or panels, on communal kitchens and washrooms, window and door perimeters on blocks and balcony and threshold joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Fencott it comes down to the same thing: the right product in a properly prepared joint.
Owners and agents with buildings around smaller places such as Fencott tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Cost factors for mastic joints
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Distance, for remote addresses
- Whether old sealant has to be cut out first
- Working within restricted access windows
- Backing rod, priming and other preparation
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Clear photos of the problem areas
- Approximate linear metres or a joint schedule
- When you need the work done
- Access details, including height
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Mastic sealing in Fencott: the local picture
Central London is about 52 miles from Fencott. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
Schools and community buildings such as Charlton-on-Otmoor Church of England Primary School need frame and external mastic kept sound like any building. Buildings close to stations like Islip station (3.2 miles west of Fencott) are often flats over shops, with frame mastic to keep sound.
Fencott is about 4 miles south of Bicester, in Oxfordshire. We cover commercial sites throughout Fencott, for single jobs and planned programmes alike.

When something else is needed

FAQs: Fencott
Do you take on block-wide or estate-wide mastic work in Fencott?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photographs and we will give a fixed quote.
Can you quote for a block close to Islip station?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
How do you handle work on occupied blocks?
We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
When is resealing likely to be due?
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.
Doing it in-house
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.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Fencott, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- Each block or building is walked and the failed joints recorded with the likely cause.
