Why it’s worth doing now in Sandwich
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open without shutting the whole car park. Tell us what has to stay open and we’ll plan around it. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
There’s no price list, since every building and every scope is different. Call for a quote.

- Old sealant cut out, never sealed over

Expansion joint sealing in Sandwich
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. If you have movement joints with split or torn sealant and water dripping through deck or ramp joints, we can help. Searching for sealant specialists in Sandwich? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around places the size of Sandwich, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Keeping the joints sound
A few simple habits keep the new joints working:
- Treat a small split as a warning, not a cosmetic issue
- Brief car park operatives to protect joint lines during winter clearance
- Keep racking legs and heavy point loads off floor joints
- Include every elevation and deck joint in periodic inspections
Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. If anything looks wrong, speak to us on 01277 525 020 or send details through our quote form with photos.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.

What affects the price in Sandwich
To price the job, we consider:
- The site’s rules and procedures
- The total length or number of joints
- Joint width, depth and condition
- How accessible the joints are
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- When you need the work done
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours
- Whether the building will be occupied during the work
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Site staff or a sealant specialist?
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
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 easy to get wrong without experience.
How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. If neighbouring businesses or buildings around Sandwich need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- 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.
- Every joint is cleared of the failed seal and any grit packed into it.
- 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.
Before we start on site
- Share the asbestos register for older buildings
- Tell staff and tenants when we will be in
- Confirm the product named in the specification
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
Advice
When to call us in Sandwich
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.
These are often picked up first by site or facilities staff:
- Damp inside where a wall movement joint has failed
- Car park joints leaking onto vehicles below
- Hardened, cracked sealant on exposed facades
- Sealant pulling off the joint face
Business parks such as Birnham Farm Business Centre (2.2 miles south-west of Sandwich) have car parks, paved areas and long brick and panel elevations, all with movement joints.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- Can the work be phased to keep areas open?
- Their approach to joint depth and backing
- Proof of insurance
Where floor joints take the most wear near Sandwich
The sea is no more than about 3 miles from Sandwich. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, and edges left open tend to break up faster. Central London is about 64 miles from Sandwich. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.
Large sites such as Ramsgate General Hospital, 5 miles north-east of Sandwich, have car parks, service roads and long elevations with movement joints in brick and panels. Schools such as Sandwich Infant School have movement joints in their walls and floors that are easy to overlook.

Questions we’re asked in Sandwich
Is a smaller place like Sandwich outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you take on a job at a hospital such as Ramsgate General Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What sealant do you use in movement joints?
We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.
Do you guarantee expansion joint work?
Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.
What’s the difference between an expansion joint and a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint and both need a flexible seal.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
How much does the work cost?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
