External mastic in Hogpits Bottom
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 use one wherever it does. We work on brickwork movement joints, concrete & block and joints between brick and frames, and people most often call us about hard, crazed mastic that has stopped moving and gaps where render, brick and frames meet.
Somewhere as small as Hogpits Bottom, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Every job comes with our 12-month guarantee, wherever you are in Hertfordshire.

How the visit works
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. Somewhere as small as Hogpits Bottom, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Tell us if parking is tricky
- Mention if the joints have been sealed before

What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. Where one has been mortared, we cut it out and reseal it with sealant if the joint can be cleared.
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 getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
- Avoid pressure-washing directly into sealant joints
- Never let anyone fill a movement joint with mortar
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
Honest limits
To be straight with you, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

Hogpits Bottom buildings and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Chenies Manor House (about 2 miles south) are a reminder that the area around Hogpits Bottom has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around Church of St Mary Magdalene (Church of England), old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Chalfont & Latimer station? Then split movement joints are easy to miss on a rental until damp shows inside.

Why it’s worth doing now in Hogpits Bottom
Sealing over the top of old mastic does not hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Around Hogpits Bottom, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
