About our external mastic in Hatford
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. Typical jobs include joints pointed up with cement by mistake and leaking joints around cladding and façade panels, across façade panels, copings & trims and render & cladding joints.
In a village or hamlet like Hatford, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What affects the quote in Hatford
Every job gets its own quote. This is what makes a difference:
- Whether the work is at height
- The product the joint needs
- How much there is to do
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Photos by email, if that is easy
- The problem you’ve noticed
- Any previous sealing or DIY work
- Where the property is

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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.
Hatford: your questions answered
What guarantee comes with external mastic in Hatford?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Hatford?
Yes, Hatford is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What colours does the sealant come in?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before any work starts from the range available.
What does external mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels.
Common problems we fix in Hatford
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Common reasons people contact us are:
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
- Cracked joints where brick meets render or frames
- Failed sealant between panels on a façade
If you live in an older home near Holy Trinity Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- How hidden problems are handled
- How the joint is cleaned and prepared
- How long to leave it before use
- What insurance they hold
How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Send us any details you have about the façade.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the building. Somewhere as small as Hatford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Keeping the joints in good condition
Aftercare is simple:
- Wash walls gently around the sealant
- Never let anyone fill a movement joint with mortar
- Tell anyone working on the walls about the movement joints
- Look over the joints every year, ideally after winter
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
Walls and rooflines in Hatford
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Longworth House (about 3.9 miles north-east) nearby, there’s older building stock in the area around Hatford as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Stanford in the Vale Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

When something else is needed
To be straight with you, some problems need a different trade:
- Rising or penetrating damp from elsewhere in the wall
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
