How we handle construction mastic in St. Ebbes
On a new build, the mastic package is one of the last trades through each area, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers, following the trades through the building as rooms and elevations become ready. If you are dealing with external joints sealed in damp or cold conditions that are now failing and internal caulk splitting as the building dries out, we can help, on brick and block movement joints, window and door perimeters and floor and skirting junctions alike. Whoever orders the work in St. Ebbes, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Conversions around smaller places like St. Ebbes often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Check frame gaps are within the sealant’s range before sealing
- Don’t force external sealing on a damp or frosty day
- Bring the mastic contractor in after the last trades are through
- Stick to the specified sealant rather than a generic substitute
Record which products went where in the handover file. Future maintenance is easier when the products are known, and tells you what to reseal with. We can confirm the handover information you need when we quote.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks, so we plan external work with that in mind.
Different surfaces, different methods
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.
Your questions answered
Can you work around term dates at a campus such as University of Oxford?
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.
Does your area include sites such as Osney Mead Industrial Estate, near St. Ebbes?
Yes. Estates, retail parks and business parks around St. Ebbes, Osney Mead Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Can you clear a mastic snag list before handover?
Yes. Snag-only work is something we take on, cutting out damaged or poor joints and resealing them.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
What we are called out for in St. Ebbes
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.
Things that typically lead to an enquiry:
- Bath and shower joints scraped during the final clean
- Cracks opening in caulked internal joints
- Window and door perimeters that won’t pass inspection
- Early adhesion failures on new external joints
For a contractor at a hotel such as Malmaison Hotel, under half a mile west of St. Ebbes, the mastic often has to be finished before a reopening date.
What to look for in a quote
- How the joint faces will be prepared and primed
- How the existing material will be dealt with
- Whether their applicators hold CSCS cards
- How long is the guarantee, and what does it include?

Other services in St. Ebbes
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Facades, frames and programmes in St. Ebbes
St. Ebbes is about 53 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. St. Ebbes sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
University estates such as University of Oxford, under half a mile north-east of St. Ebbes, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When a college such as City of Oxford College, under half a mile west of St. Ebbes, builds or refurbishes, the mastic package normally has to fit around students and staff.
