Mastic sealing for commercial buildings in Clanfield
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. If you’re dealing with leaks at window and door perimeters and damaged joints in communal entrances and corridors, we can help. Searching for sealant specialists in Clanfield? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Leave it or put it right?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Around Clanfield, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Why appoint us
- One number for every site we cover
- Public liability insurance in place
- Products installed to the manufacturer’s instructions
- 12 months’ guarantee on every job

- Location, for remote and island sites

Mastic sealing in Clanfield: the local picture
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Clanfield is about 66 miles from central London. Managed blocks of flats are a big part of commuter-belt property.
Trustees of buildings like Church of St Stephen can bring frame and external mastic into a planned maintenance list. Historic properties like Kelmscott Manor, 2.7 miles to the south-west of Clanfield, show the age of some local stock, where frame mastic must suit soft brick or stone.

FAQs: Clanfield
Does your area include sites such as Bampton Business Centre (South), near Clanfield?
Yes. Our area takes in Clanfield and its surroundings, with estates and business parks such as Bampton Business Centre (South) included. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
Do you take on block-wide or estate-wide mastic work in Clanfield?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Common problems we fix in Clanfield
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
What tends to prompt an enquiry:
- Repeated reactive repairs to the same buildings
- Water getting in round frames after rain
- Worn sealant at communal door frames
- Open joints in brickwork or panels
For a school such as Clanfield CofE Primary School, perimeter mastic on windows and doors is a holiday job.
Before you book anyone
- Proof of insurance
- Their approach to joint depth and backing
- Can the work be phased to keep areas open?
- Is the sealant right for the movement and the substrate?
What the job involves on each surface
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we will plan around them.
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.

After the work
A few simple habits keep the new joints working:
- Keep a record of when each building was resealed
- Check sealant joints during planned building inspections
- Ask residents or tenants to report leaks and draughts early
- Start inspections with the most exposed faces
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
How a job runs
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.

- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
