Expansion joint sealing near Handcross
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Doing it in-house
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 usually costs more in the end than doing them right.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Expansion joint sealing in Handcross, done properly
We’ve been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on brickwork movement joints, car park decks and ramps and precast concrete panel joints, and the usual reasons a site gets in touch are previous reseals laid over old sealant and arrises breaking up along floor joints. Searching for sealant specialists in Handcross? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Smaller community and commercial buildings around Handcross have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions about Handcross
Is Tilgate Forest Business Centre, near Handcross, within your area?
Yes, sites like Tilgate Forest Business Centre are within our area, along with the rest of Handcross. Send details of the unit and the work through our quote form for a quick quote.
Is a hospital such as Crawley Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do the joint edges need to be sound before sealing?
The edges have to be sound. If they’re damaged, we will say so before any sealing, so the new seal has something to grip.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Handcross, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- 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.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Send any specification or drawings in advance
- Tell staff and tenants when we’ll be in
- Make sure the joints can be reached
Getting a fixed quote
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 will arrange a site visit if anything is unclear.
Advice
Why it’s worth doing now in Handcross
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed, and we will say so before quoting. Around Handcross, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
Why appoint us
- CSCS-carded applicators
- RAL and finish matching where the product range allows
- Products installed to the manufacturer’s instructions
- Public liability insurance in place

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Signs you need expansion joint sealing in Handcross
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Most enquiries start with one or more of the following:
- Damp inside where a wall movement joint has failed
- Leaks through car park deck joints onto the level below
- Layers of sealant in a movement joint
- Sealant peeling off one face of the joint
On a site such as Tilgate Forest Business Centre, which lies north of Handcross, the movement joints are in car park slabs, paving and building elevations.

- Is depth set with backing rod, or bond-breaker tape in shallow joints?

Different surfaces, different methods
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
