Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
General trades versus a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Mastic sealing for commercial buildings in Middleton Stoney
Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. If you’re dealing with open joints in brickwork or panels and the same joint failures repeated across a portfolio, we can put it right. Most enquiries from Middleton Stoney start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Rural conversions near places like Middleton Stoney often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
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.

What we’re called out for in Middleton Stoney
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone and the repair soon fails.
Most enquiries start with one or more of the following:
- Failed external movement joints
- Draughts at frames across a block
- Complaints coming in block by block
- Window mastic that has split and shrunk
For owners of several units at places like Bicester Shopping Park (2.9 miles south-east of Middleton Stoney), one programme can deal with frame and external mastic across the lot.
What your quote should include
- What level of public liability insurance do they hold?
- Are they CHAS accredited or on Constructionline?
- Their plan for phasing and protecting the area
- Whether old or failed sealant will be cut out, not overlaid

What sets the cost
We price every job individually. The things that drive the figure:
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
- Joint width, depth and condition
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- Access details, including height
- Drawings or a marked-up plan, if available
- The postcode of the building
- Any dates the work must fit around
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Frames, entrances and external joints in Middleton Stoney
Middleton Stoney lies roughly 56 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Middleton Stoney is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
Churches, halls and community buildings such as Church of All Saints are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Blocks of flats and mixed-use buildings often cluster around stations such as Heyford station, 3.2 miles west of Middleton Stoney, and their window and balcony mastic tends to age at the same rate across a building.

- Broken glass or failed sealed units
