Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Work in places the size of East Preston is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- Send any specification or drawings in advance
- Let building users know which areas are affected
- Move anything stored against the joints

Advice
Expansion joint sealing in East Preston, done properly
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. Site teams most often ask us about weathered movement joint sealant that no longer flexes and damp inside where a wall movement joint has failed, on cladding panel joints, car park decks and ramps and podiums and floor movement joints. Searching for sealant specialists in East Preston? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Small units near places like East Preston are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

Expansion joint sealing in East Preston: the local picture
With the shore within about 1 mile, East Preston counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. The 3 miles around East Preston take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Across sites such as The Vinery Industrial Estate, which lies north-west of East Preston, floor and movement joints can be sealed in phases so units keep working. For a school such as East Preston Infant School, playground and building joints can be done in the holidays.

Do you need expansion joint sealing in East Preston?
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Look out for the following:
- Sealant pulling off the joint face
- Hardened, cracked sealant on exposed facades
- Torn sealant in brick or block movement joints
- Damp inside where a wall movement joint has failed
If you manage units on an estate such as Rustington Trading Estate, which lies north-west of East Preston, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Common questions from East Preston clients
Can you work at a site such as Rustington Trading Estate, by East Preston?
Yes. Estates, retail parks and business parks around East Preston, Rustington Trading Estate among them, are all within reach. Photos and a short description are enough for a first look.
Our building in East Preston is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
What sealant do you use in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane, and the specification has the final say.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Cracking or settlement that calls for an engineer’s assessment
If you’re not sure, just call 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Surfaces we seal
- Precast concrete panel joints
- Car park decks and ramps
- Cladding panel joints
- Blockwork control joints
- Brickwork movement joints
- Podiums and floor movement joints
After the work
Keep the joints in good shape with a few simple steps:
- Inspect exposed joints once the cold weather has passed
- Report split or peeling joint sealant early
- Note which joints were done, when, and with what
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint. Barriers left in place until then protect the finish.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.
Why it’s worth doing now in East Preston
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we’ll tell you honestly. For buildings in places like East Preston, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
