External Mastic in Huntercombe
External mastic in Huntercombe from a team with over 20 years’ experience. 180+ five-star Google reviews and a 4.9 rating.
- Cracked joints where brick meets render or frames
- Moss and dirt in joints with no sealant left
- Weathered mastic that no longer stretches
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Get split or bare joints resealed while the damage is small
- Check external joints each spring
- Fix overflowing gutters above sealed joints
- Keep movement joints as flexible joints, not mortar
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
How we handle external mastic in Huntercombe
For buildings in Huntercombe, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Common call-outs are for leaking joints around cladding and façade panels and gaps where render, brick and frames meet, across render & cladding joints, façade panels and concrete & block.
Around Huntercombe, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
A 12-month guarantee comes as standard.

What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours to a few days, depending on the length of joint and the access. Parking around Huntercombe is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Your questions about external mastic in Huntercombe
I let a flat near Burnham station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you cover smaller places like Huntercombe?
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.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Larger jobs naturally take longer, and we will say how long yours will take.
What is a movement joint?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Do you guarantee your work?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Walls that need new movement joints cut into them
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Surfaces we seal

For landlords and businesses
Landlords and agents in Huntercombe can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What we’re called out for in Huntercombe
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
The most common problems we see are:
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
- Plants rooting in failed movement joints
If you look after a building such as Cippenham Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Walls and rooflines in Huntercombe
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. With historic houses such as Dorney Court (about 1.4 miles south-west) nearby, there’s older building stock in the area around Huntercombe 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.
Homes close to St. Andrew's Shared Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Burnham station? Then split movement joints are easy to miss on a rental until damp shows inside.
