Cost factors for mastic packages
Each job is priced on its own details. The main factors are:
- Working within restricted access windows
- Location, for remote and island sites
- How accessible the joints are
- Joint width, depth and condition
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- The type of building and who uses it
- Photos of the joints, close up and from further back
- Your programme or deadline
- Whether an asbestos survey exists
To get a fixed quote, give us a call on 01277 525 020 or email the details over. Our quote form is another easy route.
Construction mastic in Eynsham, done properly
Most of the packages we price run well beyond frames: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. We work on cladding and panel joints, floor and skirting junctions and sanitary and kitchen joints, and what we’re called in for most is caulk cracking where joints are moving more than expected and different trades sealing to different standards. Facilities teams, main contractors and managing agents in Eynsham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
On a small site around Eynsham, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common questions from Eynsham clients
Can you take on a job at a hospital such as Radcliffe Infirmary?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Eynsham too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What happens if the weather stops external sealing?
Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Will you stick to the specified products?
We follow the specified sealant. Specifications often reference BS EN 15651 or BS 6213.
Surface by surface
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit.
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. We follow the specification and seal to a smooth, cleanable finish.

Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Work in places the size of Eynsham is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- 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.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Let us know about inductions and permits
- Warn occupants and staff about the work
- Move anything stored against the joints
Request a quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email the details over with what you know.
Related advice
Maintenance after handover
For the best life from the joints:
- Use the product the specification names
- Don’t schedule sealing before decorators and flooring are done
- Note which sealant went where at handover
- Ask cleaners to use soft cloths around fresh sealant
Expect some settlement in the first months. The right product in each joint copes with that while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating. A check of every frame before decorators start is worth the time.
Construction mastic around Eynsham: points for this area
Eynsham is about 58 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. Eynsham sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
Work at a hotel such as The Red Lion Hotel (to the south-east of Eynsham) tends to be programmed around bookings, mastic included. Hospital estates such as Radcliffe Infirmary, 5.1 miles to the east of Eynsham, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. School extensions, at buildings such as Bartholomew School, typically run to the summer holidays, mastic included.
