Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Alkerton can sit alongside others in a wider programme across Oxfordshire.
About our construction mastic in Alkerton
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal sealing often fills those days. We work on window and door perimeters, brick and block movement joints and internal decorators’ caulk, and what we are called in for most is a long mastic snag list close to completion and external joints sealed in damp or cold conditions that are now failing. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Alkerton is the same: the right product in a properly prepared joint.
Construction in and around smaller places such as Alkerton is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Questions we’re asked in Alkerton
Can you work on a hospital site such as Horton General Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you cover business parks and estates near Alkerton, such as Alkerton Oaks Business Park?
Yes. Our area takes in Alkerton and its surroundings, with estates and business parks such as Alkerton Oaks Business Park included. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Do you install fire-rated sealant as part of a package?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. Fire-stopping design and sign-off sit with the designer and building control.
Can staff carry on working while you are here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Can you fit around our programme?
We follow the trades through the building. Areas are sealed as they’re released by the site team.
Quoting for work in Alkerton
Quotes vary with the job. Expect it to depend on:
- How accessible the joints are
- Whether old sealant has to be cut out first
- Working within restricted access windows
- Site requirements such as inductions and permits
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- Whether an asbestos survey exists
- The site address and postcode
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
How a job runs
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, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Alkerton, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- 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.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
- Tell staff and tenants when we’ll be in

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Surface by surface
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker and keeps the snag list down.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification and set the depth with backing where needed.
Should maintenance staff do it?
For most general trades, sealant is a sideline. 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.
Contractors’ notes for Alkerton
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
With historic properties like Upton House (1.9 miles north of Alkerton) in the area, refurbishment work often meets old masonry that needs compatible sealants. On a healthcare site such as Horton General Hospital, 5.2 miles east of Alkerton, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. School extensions, at buildings such as Shenington Church of England Primary School, normally run to the summer holidays, mastic included.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Joint design decisions that belong to the architect or engineer
- Joints damaged after sign-off by following trades
- Frames fitted out of tolerance
