FAQs for Molehill Green
Do you work for landlords with property near Stansted Airport station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Can you do external mastic in Molehill Green?
Yes. We work across London and the South East, and Molehill Green is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before any work starts from the range available.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
How often do external joints need resealing?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
How we handle external mastic in Molehill Green
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. We work on joints between brick and frames, concrete & block and render & cladding joints, and people most often call us about joints with sealant missing in places and cracked joints where brick meets render or frames.
Somewhere as small as Molehill Green, homes and farm buildings often face open ground, 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.
There’s a 12-month guarantee on every job.

Quotes for external mastic in Molehill Green
Jobs vary more than people expect. The main factors:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Access and height
- Any mould that needs treating
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Helping us quote
To help us quote quickly, let us know:
- Whether it has been sealed before
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking

Different surfaces, different methods
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly.
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Outside joints around Molehill Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Horham Hall (about 3.2 miles north-east) are a reminder that the area around Molehill Green has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Stansted Airport station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Do you need external mastic in Molehill Green?
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Look out for any of the following:
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
- Damp patches traced to an open external joint
- Failed sealant between panels on a façade
Historic houses such as Horham Hall, about 3.2 miles north-east, show how far back building around Molehill Green goes.

Why deal with it now?
Resealing a run of joints in one go is generally better than patching one at a time. Joints of the same age tend to fail together. Around Molehill Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Render that’s blown, hollow or coming away
- Cracking across the wall rather than at a joint
- Subsidence or other structural problems
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.
What we seal
- Brickwork movement joints
- Copings & trims
- Façade panels
- Concrete & block
- Joints between brick and frames
- Render & cladding joints
How it works
Before we leave, we go over the finished joints with you. The visit itself normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. Somewhere as small as Molehill Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
