How we handle expansion joint sealing in Chinnor
A movement joint only works while its seal does. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. Site teams most often ask us about joints packed with grit and debris and water getting into the wall through a failed joint, across brickwork movement joints, precast concrete panel joints and podiums and floor movement joints. Searching for sealant specialists in Chinnor? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Rural business units around smaller places such as Chinnor often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Expansion joint sealing around Chinnor: points for this area
At about 38 miles from central London, Chinnor is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London. Rainfall across the South East, Chinnor included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
Sites like Thame Community Hospital, 4 miles to the north-west of Chinnor, carry ambulances, deliveries and visitors’ cars over their road and deck joints. For a school such as St Andrew's Church of England Primary School, playground and building joints can be done in the holidays. Estates like Junction 5 Bates Industrial Estate, 2.9 miles south of Chinnor, combine warehouse slabs, yards and loading bays, all with joints under wheels.

Commercial clients in Chinnor
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Cost factors for movement joints
Your fixed quote is built from the real scope. It allows for:
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
- Site requirements such as inductions and permits
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- How the joints are reached, and at what height
- The product your specification calls for
- Where the site is, with the postcode
- Your programme or deadline
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or send photos by email.

What else we do in Chinnor
What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Damaged metal nosings or cover plates over a joint
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
Surfaces we seal
- Blockwork control joints
- Brickwork movement joints
- Podiums and floor movement joints
- Car park decks and ramps
- Precast concrete panel joints
- Cladding panel joints
Aftercare for building managers
A few simple habits keep the new joints working:
- Leave barriers in place until fresh joint sealant has cured
- Keep scrapers and ploughs from dragging across joint sealant
- Record the sealant used and the date in the O&M file
- Check joints after long freezing spells
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. A sound seal keeps the joint working.

Several jobs near Chinnor can be grouped on one trip. Tell us your site hours and we will plan around them.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.

- Each joint is inspected and handed over with our 12-month guarantee.

Related advice
Leave it or put it right?
Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now, as damage continues meanwhile. We can split the scope into urgent and planned. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Questions about Chinnor
Do you cover business parks and estates near Chinnor, such as Junction 5 Bates Industrial Estate?
Yes, sites like Junction 5 Bates Industrial Estate are within our area, along with the rest of Chinnor. Photos and a short description are enough for a first look.
Can you work on a hospital site such as Thame Community Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long will the joint resealing take?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.
Do you use silicone or polyurethane in movement joints?
We choose a sealant with a movement capability that suits the joint as set out in BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
Can the sealant be colour-matched?
It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
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.
