Expansion joint sealing for commercial buildings in Coley Park
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Coley Park. We work on precast concrete panel joints, podiums and floor movement joints and cladding panel joints, and what we are called in for most is spalled or broken joint edges in floors and decks and rain penetration at brick or block movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Coley Park it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Coley Park, most floor and movement joint jobs are single buildings or yards. That way the right materials come on the day and the job is done in one visit where possible.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When to call us in Coley Park
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.
What tends to prompt an enquiry:
- Water getting into the wall through a failed joint
- Previous reseals laid over old sealant
- Car park joints leaking onto vehicles below
- Sealant peeling off one face of the joint
A healthcare site such as Berkshire Independent Hospital (less than half a mile west of Coley Park) depends on car parks, ramps and service yards whose joints take traffic all day.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. For a site in Coley Park, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- 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.
Preparing the site
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits

Advice
Surface by surface
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability, and we’ll confirm the colours available for the specified product.

Questions about Coley Park
Is Reading Link Retail Park, near Coley Park, within your area?
Yes. We cover Coley Park and the area around it, including industrial estates, business parks and retail parks such as Reading Link Retail Park. A few photos and the unit address let us price the work.
Is a hospital such as Berkshire Independent Hospital somewhere you can work?
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.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Can you work on car park ramps and decks?
Yes. Let us know the opening hours and which levels or bays have to stay available, and we will plan the phasing around it.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
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.
Slabs, ramps and loading bays in Coley Park
At least three named trading, business or retail sites lie within about 3 miles of Coley Park. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Coley Park sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
At places like Nimrod Industrial Estate, 0.7 miles east of Coley Park, joints are sealed a section at a time so operations carry on. Schools such as St Mary & All Saints Church of England Primary School have movement joints in their walls and floors that are easy to overlook.

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
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
- Proprietary pre-formed expansion joint systems
- Leaks coming from the membrane rather than the joint seal
If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer before you book.
