FAQs for Noak Hill
Is parking an issue for external mastic in Noak Hill?
Parking in Noak Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near Harold Wood station?
Yes, we work for landlords and letting agents. You can phone 07833 053749 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Are you insured?
Yes, we are fully insured.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away and have them redone then.
External mastic for homes and businesses in Noak Hill
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. We’re often asked to deal with weathered mastic that no longer stretches and damp patches traced to an open external joint, on copings & trims, brickwork movement joints and render & cladding joints. Whether you are looking for a mastic man, a sealant applicator or a sealant company in Noak Hill, Mr Mastic can help.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. In a converted house in Noak Hill, it’s worth checking who is responsible for the outside before booking.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Surface by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
How we quote for external mastic
Your quote is based on your job. We take into account:
- The size of the job
- Any mould that needs treating
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.
What to tell us for a quote
To help us quote quickly, let us know:
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- The address or postcode of the job
We quote each job on its own. Simply phone 07833 053749 or email us and describe the job and send pictures if you have them.
Why it’s worth doing now in Noak Hill
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear quote before any work starts.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Outside joints around Noak Hill
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
Rented homes near Harold Wood station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Church of St Thomas, old and new materials meet at the roofline and walls, which is where sealant earns its keep. As a London address, Noak Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

What we do, step by step

It normally takes a few hours to a few days, depending on the length of joint and the access. In Noak Hill, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- Mention any tricky access
- Let us know about earlier repairs to the joints
