External mastic in Best Beech Hill
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We work on brickwork movement joints, concrete & block and joints between brick and frames, and common reasons people get in touch are rain getting behind render or cladding at a joint and hard, crazed mastic that has stopped moving.
External sealant needs dry, clean surfaces, so work around Best Beech Hill is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Best Beech Hill buildings and the weather
With historic houses such as Wadhurst Castle (about 1.4 miles east) nearby, there’s older building stock in the area around Best Beech Hill as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Wadhurst Castle, about 1.4 miles east, is one of the historic houses in the wider area around Best Beech Hill. Rented homes near Wadhurst station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Uplands Community College, its movement joints, gutters and trims need looking after like any other building’s.

Best Beech Hill: your questions answered
Is Best Beech Hill in your area for external mastic?
Yes. Our work covers London and the South East, and Best Beech Hill is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Wadhurst station?

Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
How long should I leave it?
Cure times vary by product. Before we leave, we’ll tell you the cure time.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

What affects the quote in Best Beech Hill
Jobs vary more than people expect. The main factors:
- Which sealant suits the joint
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- The size of the job
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

If you’re in Best Beech Hill and need external mastic, call 0345 464 0079 or send us an email. Tell us what the problem is and where, and you’ll get a clear quote before we start.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Best Beech Hill, 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.
- Old sealant and any debris are cut and raked out.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Clear items away from the joints we’re working on

Related advice
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. In a small place like Best Beech Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email.

What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
