About our expansion joint sealing in Fernhill
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 is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. If you’re dealing with spalled or broken joint edges in floors and decks and joints packed with grit and debris, we can help. A single leaking joint is often how a building in Fernhill first comes to us: we look at the rest while we’re there and tell you what we find.
Halls, schools and small commercial buildings near places like Fernhill have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Common questions from Fernhill clients
Is hospital work, at somewhere like Spire Gatwick Park Hospital (Private), something you do?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Is Fernhill off your patch?
No. Places such as Fernhill are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What will the job cost?
Each job is quoted on its own details. To get one, call 01277 525 020 or email us with a description of the work.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Fernhill are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Tell staff and tenants when we’ll be in
- Clear stock, furniture or equipment away from the joints
- Explain the parking and delivery arrangements

After the work
Once the work is signed off, these steps help:
- Avoid parking heavy plant or pallets on joint lines
- Record the sealant used and the date in the O&M file
- Keep traffic off new joints until the cure time is up
- Act on the first tear or lifting edge rather than waiting
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. Should you spot a problem, you can ring 01277 525 020 or email a schedule or drawings and send a picture.
Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.
Cost factors for movement joints
Before we quote, we look at:
- Access and working height
- Whether the work must be split into stages
- The size and state of each joint
- Removal of failed or old sealant
We don’t publish prices, since every building and every scope is different. Call for a quote.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- How the joints are reached, and at what height
- When you need the work done
- Approximate linear metres or a joint schedule
- Photos of the joints, close up and from further back
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.
Building owners, agents and FMs in Fernhill
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Fernhill can sit alongside others in a wider programme.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Changing the joint layout or spacing of a structure
- Leaks coming from the membrane rather than the joint seal
- Cracking or settlement that calls for an engineer’s assessment
If you are not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer before you book.

What happens if it’s left?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We will flag where edges need repair before sealing. Older rural buildings around Fernhill move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.
