Chart Sutton: questions and answers
Is a smaller place like Chart Sutton outside your area?
Not at all. Chart Sutton is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can you work on a hospital site such as KIMS 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.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Expansion joint sealing for commercial buildings in Chart Sutton
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. We work on precast concrete panel joints, podiums and floor movement joints and car park decks and ramps, and what we’re called in for most is joints where the bead has lost adhesion and water dripping through deck or ramp joints. Most enquiries from Chart Sutton start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a site near Chart Sutton, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to call us in Chart Sutton
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.
Common reasons buildings call us in:
- New sealant over old, now failing
- Water getting into the wall through a failed joint
- Water dripping through deck or ramp joints
- Brittle, chalky sealant on external joints
Estates like Orchard Industrial Estate, 0.9 miles north-west of Chart Sutton, combine warehouse slabs, yards and loading bays, all with joints under wheels.

How a job runs
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Chart Sutton may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We assess the joints on site or from photos, noting widths and how each has failed.
- 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.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Advice
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Any access equipment needed
- Travel to remote or island sites
- The size and state of each joint
- Which sealant the job calls for
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What to include in your enquiry
However big the job, the same details help:
- Approximate linear metres or a joint schedule
- The type of building and who uses it
- Clear photographs of the problem areas
- The product your specification calls for
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or send photos by email.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Changing the joint layout or spacing of a structure
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Crumbling edges that would give a new bead nothing sound to grip
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Blockwork control joints
- Brickwork movement joints
- Podiums and floor movement joints
- Car park decks and ramps
- Precast concrete panel joints
- Cladding panel joints
Leave it or put it right?
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Older rural buildings around Chart Sutton move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
