About our construction mastic in Aston
Mastic tends to be one of the final packages before handover, 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. We work on internal decorators’ caulk, brick and block movement joints and cladding and panel joints, and the usual reasons a site gets in touch are a long mastic snag list close to completion and missed perimeter joints on a new elevation. Most enquiries from Aston start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Sites around smaller places like Aston can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we’ll quote to suit.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Aston may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Warn occupants and staff about the work
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints

FAQs: Aston
Does your area include sites such as Bampton Business Centre North, near Aston?
Yes, sites like Bampton Business Centre North are within our area, along with the rest of Aston. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Is hospital work, at somewhere like Longworth Hospital, something you do?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
Can staff carry on working while you’re here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Mastic packages on Aston sites
Aston is about 62 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Aston is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.
New wings at hospitals like Longworth Hospital (5.7 miles south-west of Aston) bring long runs of window and panel joints to seal. Recladding or extending a unit at a site like Bampton Business Centre North (2 miles south-west of Aston) brings panel joints and frame perimeters into the programme.
Aston is about 4 miles south of Witney, in Oxfordshire. Any commercial site in Aston is covered, for single jobs and planned programmes alike. 423 places across Oxfordshire fall within our area, including Aston. Our Oxford page has more on work in that area (12 miles or so).
Commercial sites across OX18 are covered for mastic packages. If your site is on Cote Road, Saxel Close and Woodbridge Close or close by, we can quote for mastic packages.

Surface by surface
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone, with backing rod in deeper gaps.
What else we do in Aston
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Quoting for work in Aston
Each job is priced on its own details. The main factors are:
- Any access equipment needed
- The site’s rules and procedures
- Location, for remote and island sites
- Whether the work must be split into stages
There’s no price list, since every building and every scope is different. Call for a quote.
Details that help us quote
A good diagnosis starts with the right details. Let us know:
- The asbestos register, for older buildings
- When you need the work done
- The type of building and who uses it
- Where the site is, with the postcode
To get a fixed quote, phone 01277 525 020 or email drawings and photos with the site address and an outline of the work. You can also send details through our quote form.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Faulty frames rather than failed sealant
- Joint design decisions that belong to the architect or engineer
- Approving fire stopping as compliant
If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think before you book.
Surfaces we seal
- Sanitary and kitchen joints
- Cladding and panel joints
- Internal decorators’ caulk
- Brick and block movement joints
- Window and door perimeters
- Floor and skirting junctions
When to call us in Aston
On construction sites, joints usually fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.
Common reasons buildings call us in:
- Cracks opening in caulked internal joints
- Oversized or tapered gaps around new frames
- A mastic package split between trades with no clear owner
- Frame perimeters left unsealed or poorly sealed
With historic properties like Longworth House, 3.4 miles to the south-east of Aston, in the area, refurbishment work often meets old masonry that needs compatible sealants.
