About our expansion joint sealing in Trotton
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’re dealing with water dripping through deck or ramp joints and brittle, chalky sealant on external joints, we can help. A single leaking joint is often how a building in Trotton first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Trotton, 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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Your questions answered
Does your area include sites such as Midhurst Business Centre, near Trotton?
Yes. Our area takes in Trotton and its surroundings, with estates and business parks such as Midhurst Business Centre included. Photos and a short description are enough for a first look.
Can you take on a job at a hospital such as Midhurst Community Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Why has the sealant in our expansion joints split?
Typically the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
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. Hybrid or MS polymer products suit some mixed-material joints.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Can you seal car park deck joints?
Yes, we do. These joints take wheels, salt and water, so product choice matters.
What the job involves on each surface
Car park decks and ramps
Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again.
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 in a colour confirmed for that product.

Site staff or a sealant specialist?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Proprietary pre-formed expansion joint systems
- Joints too narrow for the movement, which need redesigning by the engineer
- Leaks coming from the membrane rather than the joint seal
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.
Surfaces we seal
- Precast concrete panel joints
- Cladding panel joints
- Car park decks and ramps
- Podiums and floor movement joints
- Blockwork control joints
- Brickwork movement joints
When to call us in Trotton
Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch.
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
- Sealant peeling off one face of the joint
- Torn sealant in brick or block movement joints
For a school such as Stedham Primary School, playground and building joints can be done in the holidays.
What to look for in a quote
- The named product and why it was chosen
- How the existing material will be dealt with
- Proof of insurance
- Do they follow the manufacturer’s priming guidance?
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Trotton may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Share the asbestos register for older buildings
- Point out any areas we must not close
- Tell us what induction or permit system the site runs

Advice
What sets the cost
Before we quote, we look at:
- Site requirements such as inductions and permits
- How much existing material needs removing
- Access and working height
- Joint width, depth and condition
A quote for movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
What to include in your enquiry
We can often quote from photos and a few details. Please tell us:
- Any dates the work must fit around
- The type of building and who uses it
- The postcode of the building
- Clear photographs of the problem areas

Where floor joints take the most wear near Trotton
Trotton is in the South East, one of the UK’s drier regions. 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. The 3 miles around Trotton take in two named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Office parks like Midhurst Business Centre (to the east of Trotton) have decks, ramps and clad elevations whose joints take movement every day. Another example is Holmbush Industrial Estate, which lies south-east of Trotton, where floors and yards would be done in stages around the occupiers.
