About our expansion joint sealing in Barford St John
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. Site teams most often ask us about expansion joints split through the centre of the bead and expansion joints filled with dirt and stones, on precast concrete panel joints, cladding panel joints and brickwork movement joints. Facilities teams, main contractors and managing agents in Barford St John tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Smaller community and commercial buildings around Barford St John have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Different surfaces, different methods
Joints between different materials
Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed, and we’ll tell you if any edges need repairing first.
Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Questions about Barford St John
Do you take on work at healthcare sites like Horton General Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Barford St John outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. If others near Barford St John need work, visits can be combined. A fixed quote is given before anything starts.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints

Advice
What sets the cost
Your fixed quote is built from the real scope. It allows for:
- The site’s rules and procedures
- Removal of failed or old sealant
- Phasing around occupants
- Which sealant the job calls for
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Specification clauses that apply
- Approximate linear metres or a joint schedule
- Clear photographs of the problem areas
- Any dates the work must fit around
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- A joint that has to be widened or re-detailed before it can work
- Cracking or settlement that calls for an engineer’s assessment
- Leaks coming from the membrane rather than the joint seal
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly.
What we seal

Signs you need expansion joint sealing in Barford St John
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.
Common reasons buildings call us in:
- Joints packed with grit and debris
- Rain penetration at brick or block movement joints
- Expansion joints split through the centre of the bead
- Arrises breaking up along floor joints
