Construction mastic in Didcot
Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. If you are dealing with external joints sealed in damp or cold conditions that are now failing and caulk cracking where joints are moving more than expected, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Didcot, that means joint design, primers and backing rod as standard.
For contractors on site in a town like Didcot, the mastic has to fit the programme: sealing as scaffold comes down or as each floor is decorated, and snagging before handover. Send drawings and the programme and we’ll price to suit.
Our workmanship is guaranteed for 12 months, in Didcot as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Contractors’ notes for Didcot
Rainfall across the South East, Didcot included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Didcot lies roughly 50 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
Hospital estates such as Didcot Hospital, 0.7 miles to the south-west of Didcot, 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. Units on estates such as Market Place Shopping Centre, under half a mile to the south-east of Didcot, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Projects at schools like Manor Primary School work to term dates, so mastic is programmed tightly.
Didcot is about 10 miles south of Oxford, in Oxfordshire.

Advice
What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Oversized gaps that need packing or adjustment by others
- Faulty frames rather than failed sealant
- Rework caused by others damaging completed areas
Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly.
Where we work in Didcot

Questions about Didcot
Can you keep pace with our programme in Didcot?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you take on a job at a hospital such as Didcot Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do you work in Didcot?
Yes. Sites across Didcot are covered.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Public liability insurance is in place.
Can you clear a mastic snag list before handover?
Yes. Send the snag list or photos and we’ll price it.
Should maintenance staff do it?
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Rough lengths or quantities, or drawings if you have them
- The product your specification calls for
- When you need the work done
- Where the site is, with the postcode

Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Didcot can sit alongside others in a wider programme.
How the job changes by surface
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. Joints are sealed smooth so they’re easy to clean.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly.
