External mastic in Filmore Hill, done properly
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we do not skip that step. If you have rain getting behind render or cladding at a joint and moss and dirt in joints with no sealant left, we can put it right, whatever the surface.
In a village or hamlet like Filmore Hill, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Each job carries a 12-month guarantee.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Outside joints around Filmore Hill
With historic houses such as Hinton Ampner House (about 4.2 miles west) nearby, there’s older building stock in the area around Filmore Hill 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Holy Trinity Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. In and around Filmore Hill, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Leave the joints unpainted unless we have said otherwise
- Look over the joints every year, ideally after winter
- Wash walls gently around the sealant
- Act on the first splits you see
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Adding movement joints to masonry that has none
- Subsidence or other structural problems
- Render that’s blown, hollow or coming away
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.

How the visit works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. For a village or hamlet like Filmore Hill, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- The joint faces are cleaned and primed where the sealant needs it.
- 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
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

Jobs vary more than people expect. What affects the quote:
- When we can work, for business premises
- How many areas need sealing
- The size of the job
- Mould in or behind the old joints
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
What to tell us when you ask for a quote:
- The rough size of the job

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. A flexible sealant bridges the two.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out.
Common questions in Filmore Hill
Do you cover Filmore Hill for external mastic?
Yes, Filmore Hill is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Filmore Hill?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
How do you reach high-level joints?
It depends on the building. Send us pictures and a rough idea of the height.
Do you have insurance?
Yes. We are fully insured.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
Leave it or put it right?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a small place like Filmore Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
