Expansion joint sealing for commercial buildings in Crowmarsh Gifford
Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. If you have expansion joints filled with dirt and stones and brittle, chalky sealant on external joints, we can help, on cladding panel joints, blockwork control joints and precast concrete panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Crowmarsh Gifford, preparation and product choice get the time they need.
Jobs around smaller places like Crowmarsh Gifford are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. If others near Crowmarsh Gifford need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close
Getting a fixed quote

Related advice
Signs you need expansion joint sealing in Crowmarsh Gifford
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again.
Most enquiries start with something like this:
- Water getting into the wall through a failed joint
- Movement joints with split or torn sealant
- Sealant pulling off the joint face
- Previous reseals laid over old sealant
For a school such as Crowmarsh Gifford Church of England School, playground and building joints can be done in the holidays.
Questions to ask before you book
- How they handle RAMS and site documents
- Can the work be phased to keep areas open?
- Health and safety accreditation such as CHAS
- Is the sealant right for the movement and the substrate?
Questions about Crowmarsh Gifford
Does your area include sites such as Hithercroft Industrial Estate, near Crowmarsh Gifford?
Yes. We cover Crowmarsh Gifford and the area around it, including industrial estates, business parks and retail parks such as Hithercroft Industrial Estate. A few photographs and the unit address let us price the work.
Is Crowmarsh Gifford too far out for you?
Not at all. Crowmarsh Gifford is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Can you seal joints in cold or wet weather?
Weather matters for any external joint. Indoor joints can usually carry on regardless.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Act on the first tear or lifting edge rather than waiting
- Raise snow-clearing blades over deck joints where possible
- Plan racking layouts so feet don’t land on a joint
- Keep product details with the building records for the next reseal
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.
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. A sound seal keeps the joint working.
Owners, agents and contractors
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Floors, slabs and movement joints in Crowmarsh Gifford

The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.
Hospitals like Wallingford Community Hospital, 0.9 miles west of Crowmarsh Gifford, have multi-storey or surface car parks whose joints carry vehicles round the clock. Warehouse floors on estates like Hithercroft Industrial Estate (to the west of Crowmarsh Gifford) carry pallet trucks and forklifts over every saw-cut joint.

Why deal with it now?
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we’ll tell you honestly. One visit to deal with every failing joint makes more sense than several trips to a place like Crowmarsh Gifford, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
