Expansion joint sealing for commercial buildings in Martin
Mastic Doctor has sealed movement joints since 2005. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on brickwork movement joints, podiums and floor movement joints and car park decks and ramps, and the usual reasons a site gets in touch are joints where the bead has lost adhesion and expansion joints filled with dirt and stones. A specialist sealant contractor works differently from a general builder: on jobs in Martin, preparation and product choice get the time they need.
Around smaller places such as Martin, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

FAQs: Martin
Can you work at a site such as White Cliffs Business Park, by Martin?
Yes, sites like White Cliffs Business Park are within our area, along with the rest of Martin. Send details of the unit and the work through our quote form for a quick quote.
Can you work on a hospital site such as Royal Victoria Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
What guarantee do you give on joint sealing?
It’s backed by our 12-month guarantee. If a joint we sealed fails inside the 12 months, let us know.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What exactly is a movement joint?
It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint.
More services for Martin
Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
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.
Do you need expansion joint sealing in Martin?
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.
Most enquiries start with something like this:
- Car park joints leaking onto vehicles below
- Sealant peeling off one face of the joint
- Layers of sealant in a movement joint
- Chipped joint edges on forklift routes
For a school such as Langdon Primary School, playground and building joints can be done in the holidays.
Questions to ask before you book

On site: what to expect
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a building around Martin, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Point out parking and an unloading spot
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints

Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Clear dirt from joint lines during routine cleaning
- Record the sealant used and the date in the O&M file
- Avoid parking heavy plant or pallets on joint lines
- Raise snow-clearing blades over deck joints where possible
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Floors, slabs and movement joints in Martin
The sea is no more than about 3 miles from Martin. Open joints in coastal car parks and yards let in salt-laden water as well as grit, which is why split joints are worth sealing before the edges deteriorate. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.
Business parks such as White Cliffs Business Park, 2.4 miles south-west of Martin, have car parks, paved areas and long brick and panel elevations, all with movement joints. Hospital campuses such as Royal Victoria Hospital, 3.6 miles south-west of Martin, grow in stages, leaving movement joints wherever new blocks meet old.
