How we handle external mastic in Finkley Down
On houses, flats and commercial buildings across Finkley Down, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Common call-outs are for rain getting behind render or cladding at a joint and weathered mastic that no longer stretches, across brickwork movement joints, concrete & block and copings & trims.
Somewhere as small as Finkley Down, 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- How much there is to do

Why it’s worth doing now in Finkley Down
Sealing over the top of old mastic does not hold for long. New sealant doesn’t bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around Finkley Down can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.
Why book with us
- Old sealant always removed completely
- White, clear, grey or coloured to suit, where the product allows
- Anti-fungal sanitary silicone in wet areas
- Colour agreed with you before we start

How it works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Finkley Down, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Get split or bare joints resealed while the damage is small
- Ask before painting over external sealant
- Look over the joints every year, ideally after winter
- Wash walls gently around the sealant
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Signs you need external mastic in Finkley Down
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
The most common problems we see are:
- Leaking joints around cladding and façade panels
- Weeds or debris growing in open joints
- Weathered mastic that no longer stretches
- Damp patches traced to an open external joint
For site and facilities teams at buildings such as Vigo Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Common questions in Finkley Down
Can you help a landlord with a rental near Andover station?

Will you come out to Finkley Down?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
How long will you be here?
That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on the building. We will tell you when we quote.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Outside joints around Finkley Down
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.
If you let a flat or house near Andover station, outside joints that have cracked can let damp into a rental, so check them between lets.
