Floors, slabs and movement joints in Long Sutton
Long Sutton lies roughly 41 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Long Sutton sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.
Sites like Alton Community Hospital, 5.8 miles to the south of Long Sutton, carry ambulances, deliveries and visitors’ cars over their road and deck joints. For a school such as Long Sutton Church of England Primary School, playground and building joints can be done in the holidays.

Expansion joint sealing in Long Sutton, done properly
Mastic Doctor has sealed movement joints since 2005. Our applicators are CSCS-carded, we are 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 car park decks and ramps, podiums and floor movement joints and blockwork control joints, and the usual reasons a site gets in touch are expansion joints split through the centre of the bead and car park joints leaking onto vehicles below. Whether you call it commercial sealant work, mastic application or joint sealing, in Long Sutton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Jobs around smaller places like Long Sutton are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Keeping the joints sound
After handover, these steps help:
- Keep product details with the building records for the next reseal
- Report split or peeling joint sealant early
- Keep stones and debris out of open joint lines
- Reopen bays and walkways only after the stated cure time
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check. Should you spot a problem, you can give us a call on 01277 525 020 or send photos by email and send a picture.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.
Why act early in Long Sutton
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. We can split the scope into urgent and planned. Converted and older buildings near places like Long Sutton tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
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’ll put a fixed figure on it.
Why choose Mastic Doctor in Long Sutton

- RAL and finish matching where the product range allows

Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Long Sutton are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Share the asbestos register for older buildings
- Flag any permit to work we’ll need

Common questions from Long Sutton clients
Does a site in Long Sutton have to shut while its joints are sealed?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.
Is Long Sutton off your patch?
No. Places such as Long Sutton are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
What’s the difference between an expansion joint and a movement joint?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Why do our movement joints keep failing?
The way it has failed usually tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Concrete or masonry repairs along the arrises
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.
